Definitions

  • the present invention relates generally to advertising and, in particular, to a method and system for placing advertisements in a computer network, such as a wide area network or a metropolitan area network.
  • a number of information services are currently offered on wide area public networks, such as the Internet.
  • the basic model of these services is that a query is processed and a set of answers is returned.
  • a number of yellow page searchable directories have been developed in which users can query categories of products or services (e.g., new car dealers) and the system returns a set of vendors satisfying the query.
  • Public networks such as the Internet
  • search engines used in public networks are sponsored by a single vendor or company.
  • the sponsoring vendor or company will often have an advertisement displayed on a user's computer screen during use of the search engine.
  • Other search engines display randomly selected advertisements from a fixed set of advertisements.
  • WWW World Wide Web
  • advertisements are sometimes referred to as "banner” advertisements because they simulate a banner that the user sees as the user is traveling down a "road” on the computer network.
  • banner advertisements are typically tied to a particular search page that the user encounters during the search.
  • the current state of the art is such that when the user uses a search engine, a randomly selected advertisement is shown as if it is part of the search page.
  • the user may enter a search request to see a home page on cooking and, as a part of that page, the existing systems might display an advertisement about cars.
  • This is a problem, of course, because there is no connection made between the content of the advertisements or the message of the advertisements and what the user is actually searching.
  • Another problem with the current state of the art is that there is no guarantee associated with the advertisements that they will be shown a certain number of times or in a certain place on the page with respect to the other pieces of data on that page.
  • the existing systems for placing advertisements on computer networks, such as the Internet fail to take full advantage of the interactive/demand driven environment of the online medium.
  • the present invention provides a new process and system for online advertising. This new process will be referred to throughout this application as query-based advertising ("QBA") .
  • QBA query-based advertising
  • advertisements are primarily triggered by user queries.
  • User queries refer to requests from an information consumer for one or more pages of information from a computer network.
  • the query triggers advertisements.
  • a server containing a collection of advertisements is placed in electronic communication with a computer network.
  • the computer network is preferably a wide area network, such as the Internet, or a metropolitan area network.
  • the phrase "computer network" refers to any public or private data communications network.
  • the advertisements on the server are not tied to any particular page containing information on the computer network. Rather, the advertisements are contained on the server, distinct from the pages that may or may not later carry the advertisements.
  • the pages by themselves have no advertisements. Thus, the pages are analogous to a newspaper or magazine devoid of any advertisements.
  • the present invention upon receiving the user's request, retrieves advertisements that are related to the user's action, dynamically mixes the advertisements with the content of the pages according to a particular layout, and displays the pages with focused, targeted advertisements as a part of the page.
  • the advertisements can be made to satisfy a set of constraints requested by the advertiser, as well as the constraints of the publisher of the page, as further discussed below.
  • the advertisement triggering mechanism of the present invention is not random or coincidental, but rather, is prespecified in advance. This specification will be referred to in this application as a contract.
  • a contract specifies the marketing rules that link advertisements with specific queries.
  • a diet soft drink advertisement may be shown when a user asks for a page about exercising equipment.
  • These rules are specified by advertisers implementing the concept of "focus” or “relevance” of advertisements and help the advertisers to target a specific audience.
  • Owners of pages specify the focus content of their pages through special tags within a page. These tags are not displayed to the information consumer; the tags are used to decide what advertisement can be shown when the page is requested by a consumer.
  • the notion of a contract goes well beyond just marketing rules.
  • the advertising space on the online medium although technically unlimited, is severely restricted by the user's attention span. Placing advertisements on the first page which constitutes the answer to a query gives the advertisements much higher probability to be seen than on later pages of the answer.
  • Prime space will be used in this application to refer to limited advertising space on the first page of the answer to a query. Prime space is, in principle, as attractive as prime time television. Prime space, like prime time, is limited so it may be impossible to show all the relevant advertisements in prime space.
  • the present invention provides guarantees to advertisers through the use of contracts .
  • the contracts provide tools to specify such guarantees and to enforce them.
  • the present invention provides the following types of guarantees (or "contracts") to advertisers:
  • Ratio-based The ad will be shown in prime space no less than a certain percentage of the times a relevant query is made by a searcher.
  • Exclusive or Competitive Ad A is never to be shown in prime space when ad B is shown.
  • Dependent Ad A is to be shown with a predetermined probability when ad B is shown in prime space.
  • Story An ad consisting of several sub-ads will be shown in prime space in sequence to a consumer.
  • Frequency-based The ad will be shown in prime space a certain number of times in a given time period (e.g., 100 times per month) .
  • the contracts may also specify the type of layout used to mix ads together with the data. This may include the layout types, and so forth.
  • the present invention also provides means for determining whether there are any contracts that cannot be satisfied. For example, if the prime space is sufficient to hold only two ads, it is impossible to guarantee 100% ratio for more than two ads. Similarly, if ad A is never to be shown when ad B is shown and if both ad A and ad B are equally relevant according to focus matching, then it is impossible to guarantee ratios above 50% for both ads A and B.
  • the present invention uses algorithms to check for contract consistency to ensure that all contracts that are accepted can be properly satisfied.
  • An advertiser can ask for a certain contract (e.g., 5% relative coverage in prime space) and the present invention will determine whether that contract can be satisfied. If not, the system suggests what coverage it can provide. After the contract is determined to be consistent, the present invention will enforce the contract by displaying advertisements in accordance with the contract.
  • QBA Quality of Service
  • the query asks for a page that has a focus.
  • Ads that are resident in the system are checked to determine which ads can potentially be placed on the page in question. This decision is based on matching the focus of a page with the focus of the ad.
  • the contract enforcement feature of the present invention ensures that the ads that are placed on the page are consistent with the contracts signed by the system with the advertiser.
  • QBA Quality of Service
  • pages on the WWW have a fixed a priori agreed upon area on a page for advertising.
  • the present invention dynamically determines where an advertisement should be placed.
  • the present invention permits owners of pages to be free to organize the layouts of their pages.
  • the page owner makes the final determination of where an advertisement should or should not be placed.
  • the page owner can specify where an advertisement can be placed by placing a special tag ("ad space") on their page. Like the focus tag, this ad space tag is not visible to the consumer. It is a directive to the advertising system that the tag denotes space available for advertising, i.e., the tag can be thought of as a billboard stating "this space available for advertising."
  • the present invention also provides a download delay- time advertising feature.
  • the present invention uses the download delay-time to display ads to the consumer. This will be referred to as down-load delay time advertising.
  • the time that the consumer would have waited for a page to be downloaded is utilized to expose the consumer to ads.
  • the consumer does not experience a delay due to advertising by the present invention. Only the preexisting delay time is utilized by the advertising system.
  • the present invention provides a system and method for advertising on a computer network, comprising a server containing a plurality of advertisements, means for electronically connecting the server to a computer network, and means for selecting and retrieving an advertisement from the server in response to a query entered on the network.
  • the selecting means comprises means for ensuring that a selected advertisement is relevant to the query.
  • a mixer means is provided for combining a retrieved advertisement with a content page returned by the computer network in response to the query.
  • the mixer means comprises a layout manager means for computing an optimum layout of a combined page containing the retrieved advertisement and the content page.
  • the mixer means also comprises a typography manager means for detecting special tags and HTML rules in the content page and for determining which part of the content page the selected advertisement can be displayed on.
  • the content page is provided by a home page dispatcher, a search engine, or a generic HTML content provider in response to the query.
  • a transaction means is provided for permitting a user to make a transaction with the advertiser by interacting with the displayed advertisement.
  • a prime space manager means is provided for controlling when the advertisements contained on the server are selected by the selecting means, the control being based upon respective advertiser contracts associated with each of the advertisements.
  • An ad placement means is provided for placing new advertisements on the server, the ad placement means having means for entering an advertiser contract for each advertisement placed on the server and means for checking a new advertiser contract for consistency with existing advertiser contracts.
  • a local client means is provided for displaying a retrieved advertisement only during a download delay time period in which a user is waiting for a content page to be downloaded in response to the query.
  • a means for refreshing a displayed advertisement after a predetermined time period of inactivity by the user, and a means for replacing a displayed advertisement with a downloaded content page as soon as the content page is received by the client are also provided.
  • the system includes means for calculating a search time estimation for the query, and means for combining a page containing the search time estimation and a retrieved advertisement.
  • the system also includes means for determining a geographic location of a user, and means for selecting an advertisement based upon the user's geographic location.

  • the layout manager 10 is primarily responsible for the computation of the layout of a page to be displayed to a client. Other modules of the system compute the necessary data that is to be displayed, as described below. The layout manager 10 then accepts this data from the other modules and computes the optimum layout for the display.
  • the layout manager 10 uses two sub-components to determine the optimum layout; a rule base and a layout data base within the layout manager (collectively shown as the layout rules component 11 in Fig. 1) .
  • the layout data base contains a collection of templates that have been predefined and stored in the layout data base.
  • the rule base contains a collection of rules defined by the user or by the placer of the layout manager to ascertain which layout templates are best under what set of conditions.
  • the layout manager 10 receives the data to display, it invokes various rules in the layout rules to figure out which rule to trigger and, hence, decides on one layout as being the best under the present set of conditions.
  • the variables used in the rules are the amount of data that is to be displayed, the kind of data that is to be displayed, the amount of text, the amount of advertising material, and the size of the various maps and multi-media icons that are to be displayed. Based on these variables, the rules are checked and one or more rules are picked as delineating the best layout that can be found. The layout manager 10 then arbitrarily picks one of the rules that it thinks are the best and picks that layout, inserts the data given to it in the layout template, and gives the final product to the client to be displayed.
  • the variables that are expressed in the rules are based on a number of parameters including the size of the text, the amount of text, the size of the maps, the size of the images, and the size of the advertisement. In principle, there is no limit as to the number of parameters that one can achieve using the layout manager 10.
  • the rules are preferably expressed in a programming language general enough to take any other parameters that one may desire to furnish.
  • the layout rules are constructed based on various parameters.
  • the layout rules are then checked and used to pinpoint the exact template to be used for a certain kind of data situation.
  • the template is then filled in by the layout manager 10 to provide a display to the client.
  • the segmenter 12 will be described.
  • the segmenter 12 is responsible for analyzing an HTML page and for extracting the relevant data from the HTML page.
  • the purpose of the segmenter 12 is that, if the system is given a page constructed by another component or by some other content provider, the segmenter 12 will try to find reasonable places within that page where a certain advertisement could be inserted dynamically.
  • the segmenter 12 uses various rules for finding advertising space within a page, and for preventing the essential layout of the page from being disturbed.
  • the segmenter 12 looks for certain special tags inserted by the designer of the HTML page and replaces those special tags with advertisements or other types of information that it has been given. The segmenter 12 then looks at the page, decides where to insert ads, and provides that information to the layout manager 10.
  • the typography manager 14 is the main input device to the layout manager 10.
  • the typography manager 14 ' s role is to "render" the page. By rendering the page it is meant that the typography manager 14 takes various kinds of input that has to go on a page and decides which part of the information has to go on the page and which part of the information could in fact be deleted.
  • the typography manager 14 is similar in function to a typographer in a traditional publishing situation.
  • the typography manager 14 has the final say in what data gets sent to the layout manager 10.
  • the typography manager 14 also detects special tags and special HTML rules that tell it where the markups of the HTML page are supposed to happen.
  • the layout manager 10 and the typography manager 14 collaborate on coming up with a page. This page in its final form is then passed to the gate 15.
  • the gate 15 transfers a page from the system of the present invention to the client.
  • the gate 15, therefore, provides the gate between the client and the server.
  • the gate 15 gives the page that it wants to display to the WWW Daemon 16 and the Daemon interacts in turn with the client
  • a user requests a particular piece of information through one of the clients 17.
  • the user's request is given to the WWW Daemon 16, which passes the information to the gate 15.
  • the gate 15 decides what piece of information is being requested by the user and finds other relevant pieces of information that can be commingled with what the user has asked.
  • the user for example, might ask the system to see certain car dealers, to find a phone number of a car dealer, or to get a page of a particular magazine.
  • the gate 15 at this point gives the request to the matching rule engine 18 ("MRE") .
  • MRE matching rule engine 18
  • the purpose of the MRE 18 is to look at the content of the user's query and to find a category within its active index SIC 19 that matches the same type. If the user has asked for car dealers, the MRE
  • the MRE 18 at this point then returns to the gate 15 the category index of the user's query. If the user had asked about cars or about family sedans or about sports cars, at this point the MRE 18 would have figured out that the user's interest falls into a certain category. Based on the user's interest category, the system then retrieves the advertisements that are relevant to that category. Thus, the purpose of the MRE 18 is to figure out what the user requested, to place the user's request in a category of a classification system (i.e., the active index SIC 19) and, based on that classification, to retrieve relevant advertisements. At this point there may be several hundred related advertisements retrieved from the category containing the user's request.
  • a classification system i.e., the active index SIC 19
  • prime space manager 20 comes into play.
  • the purpose of the prime space manager 20 is to prioritize the advertisements that are to be shown to the user.
  • the system must determine which five of the ads to show.
  • the operation of the prime space manager 20 is based on a set of contracts that were accepted when the advertisers placed their advertisements with the system.
  • the system supports the following five basic types of contracts : 1.
  • Ad A is to be shown with a predetermined probability when ad B is shown in prime space.
  • Ad A is never to be shown in prime space when ad B is shown.
  • Story An ad consisting of several sub-ads will be shown in prime space in a particular sequence to a consumer.
  • Frequency-based The ad will be shown in prime space a certain number of times in a given time period (e.g., 100 times per month) . Additionally, the contracts may also specify the type of the layout used to mix ads together with the data. This includes the layout types, and so forth. The various contracts used by the system will now be discussed in more detail .
  • the ratio-based contracts are used where an advertiser wants the advertisement to be displayed a certain percentage of the time in prime space. In other words, when a query is received that is related to the business of the advertiser, the advertiser is guaranteed that its advertisement will be on the first screen of information displayed to the user a certain percentage of the time (e.g., 15% of the time) . This percentage is called the coverage guarantee.
  • the ratio-based contract provides a coverage guarantee to the advertiser that its advertisement will be displayed X% of the time for every relevant query.
  • the second kind of contract that the system supports is referred to as a dependent contract.
  • the dependent contract guarantees that one advertiser's ad can be shown in conjunction with another advertiser's ad on the same screen. For example, a travel destination advertisement
  • a credit card advertisement e.g., "Pay for your ticket through VISA”
  • the system can support contracts that satisfy the needs of two or more advertisers at the same time .
  • the third type of contact supported by the system is called an exclusive or competitive contract.
  • This type of contract can be used to guarantee that an advertiser's ad is not shown at the same time or on the same page as a competitor's advertisement.
  • a beverage manufacturer e.g., Coca-Cola
  • a competing beverage manufacturer's e.g., Pepsi's
  • the fourth kind of contract is called a story contract .
  • This type of contract is used to guarantee an advertising package in which a sequence of two or more ads are shown together.
  • the ads can be displayed so that the user sees a first part of the advertisement, then sees a second part of the ad, and then sees a third part of the ad and so on.
  • an advertisement for coffee might consist of a picture on a first page showing somebody drinking a cup of coffee; a picture on a second page showing them putting the coffee cup away; and a picture on a third page identifying the name of the advertiser's product (e.g., "Maxwell House makes a good cup of coffee") .
  • the story contract guarantees that an advertiser's ads will be shown in the form of a story.
  • the story contract is desirable where a group of ads must be shown together in a particular order to make sense.
  • the fifth kind of contract is the frequency-based contract. This contract is used where the advertiser wants to guarantee that its advertisement will be shown a certain number of times over a given time period (e.g., 100 times per week) .
  • an advertiser can enter a story contract which also guarantees that its advertisement will not be shown at the same time as its competitors ads are shown, that its advertisement will be shown at the same time that a related advertisement is shown, and that its advertisement will be shown in prime space a certain percentage of the time.
  • the prime space manager 20 has the responsibility of determining all the possible advertisements that can be shown in conjunction with the information requested by the user. The prime space manager 20 then decides which ads to show based on the particular contracts that have been signed. If a contract has already been entered with an advertiser's competitor, the prime space manager 20 will make sure that it can in fact satisfy the new contract with the advertiser. Thus, the prime space manager 20 dynamically makes a decision of which advertisements to show given the amount and the number of advertisements that it can possibly show. The end result of the prime space manager 20 ' s computation is that the system knows exactly which advertisements can and will be shown to the user. These advertisements are then given to the gate 15.
  • the gate 15 at this point gives the ads to the typography manager 14, and the typography manager 14 determines how best to display the information.
  • the page information then comes back to the gate 15 and is forwarded to the client 17.

  • a logging module 22 of the system performs extensive logging of what the user has asked, what advertisements were shown, how long the advertisements were shown, and which advertisements were shown to which user.
  • the logging module 22 then stores these logs in a SYS logs database 23.
  • Various scanned reports can be produced and defined using the information in the SYS logs database 23.
  • a local client 24 of the present invention provides a download delay-time advertising feature. Download delay time refers to the delay experienced by most users of computer networks from the moment a page is requested to the time the page is downloaded to their browser.
  • the download delay-time advertising feature utilizes the time that the consumer would have waited for a page to be downloaded to expose the consumer to ads. Once a page (or a subpart of the page) has been downloaded to the consumer's browser and is available to be displayed, the ads are replaced by the page content .
  • the present invention uses this delay time to show advertisements, while taking care that the delay time of the user is not increased by showing the ad.
  • the only time an advertisement is displayed is the time that the user would have had to wait anyway. While the user waits for the page, the user can view the advertisements on the local client 24.
  • the information brokers or content providers shown in Fig. 1 include a home page dispatcher 25, a search engine INFORMIX 26, and a generic HTML 27.
  • a "publisher” can include virtually anyone that provides content to the network.
  • anyone who is a home page owner is a publisher in the category shown as Generic HTML 27.
  • a second kind of publisher is the search engine publisher 26, which includes phone company yellow page providers, such as NYNEX.
  • a third kind of publisher is the so-called home page dispatchers, which include traditional magazines and newspapers, such as Business Week.
  • the present invention distinguishes between these three types of publishers. If the publisher is a home page dispatcher 25, the publisher provides its own content and intersperses the content with certain special tags indicating where ads can and cannot be placed and indicating where the focus of the content is about certain topics . These special tags are then used to trigger certain actions in the system of the present invention relating to the type of content contained on the page and the kinds of advertisements that can be placed on the page.
  • the second kind of publisher that the present invention is used with is the search engine publisher 26.
  • the search engine publisher 26 there are many companies on the WWW that permit users to query their database and then return a set of answers from the database to the user.
  • a telephone company may have a site that allows a user to obtain a set of phone numbers and business names for a particular type of business (i.e., a yellow page directory) .
  • the search engine publisher 26 is distinguished from the home page dispatcher 25 in the sense that the content returned by the search engine publisher 26 does not contain any special tags or meta comments put in by the publisher to define the layout of the content and the ads.
  • the layout manager 10 of the present invention computes the optimum layout based upon the rules and layout templates, as described above. The final result, therefore, is that output is taken from the search engine publisher 26, adorned with certain relevant advertisements, and then shown to the users.
  • the third kind of publisher, the generic HTML publisher 27, includes those publishers that the present invention assumes are people who have designed their own home page, perhaps taking great care to provide a desired appearance. These publishers will probably not have inserted any special tags or meta comments into their home page to guide the advertising system of the present invention.
  • the system of the present invention can either try to find a space in the home page that it thinks is reasonable without violating the desired appearance of the page, or it can insert the advertisement before or after the page. That is, if the segmenter 12 cannot find a suitable place within the page that the generic HTML publisher 27 has already designed, it will place the advertisement on the proceeding or the following page. This is more likely to occur if the owner of the page has not provided any special tags or meta comments, or if copyright concerns prevent the insertion of a certain advertisement within the page.
  • the present invention partitions the publishers (i.e, the information brokers) into three categories: the home page dispatchers 25, the search engine publishers 26, and the generic HTML home page providers 27.
  • the home page dispatchers 25 intersperse their content with special tags or meta comments which helps the present invention in determining where to place the advertisements and what kind of advertisements to place
  • the search engine kind of publishers 26 return unadorned results of queries and the present invention is free to reformat and relay out the set of answers
  • the generic HTML home page publishers 27 are publishers that have meticulously crafted their home pages, usually without special tags or meta comments, so that no guidance is provided to determine an appropriate space for placing an ad.
  • the segmenter 12 which is the module of the present invention whose responsibility is to find a place somewhere on a generic HTML page to place an advertisement, may not succeed in finding a space on a generic HTML home page. In this case, it will either place the advertisement on a proceeding or a following page. Most, if not all, of the publishers on the WWW will fall into one or more of these three categories .

This creates a spectrum of objective versus subjective content that has to be evaluated. That is, it must be determined how much subjective content to provide and how much objective content to provide. If the publisher is a yellow page publisher, the layout manager 10 must decide how many telephone listings to display and how much of the page to fill with advertisements. The system could, for example, display only three telephone listings and fill the rest of the page with advertisements, or the system could display twenty telephone listings and only one ad.

  • the prime space manager 20 has a prime space algorithm 150 that accepts as inputs the list of relevant ads that are related to the query at hand, the size of the prime space, and the list of all ad contracts. The prime space manager 20 then looks at all the ad contracts and determines which advertisements to show to the user. The prime space manager 20 then updates the contracts (step
  • the prime space manager 20 then provides a list of prime space ads to be shown to the appropriate module. That is, the prime space manager 20 accepts a possibly very long list of advertisements and, based on the contracts that it has, filters the ads to a smaller list containing exactly the number of advertisement ⁇ that it can show based on the size of prime space.
  • prime space algorithms are provided to further illustrate the function and operation of the prime space manager 20 of the present invention. It should be noted that many variations of these algorithms are possible, and that the specific examples provided are for purposes of illustration only.
  • the prime space on a user's terminal means the first screen of data which constitutes the answer to the user's query (plus the relevant advertisements) .
  • advertisers will be assured of "fair" treatment in the sense that their advertisements will be presented to the targeted users in a manner that is commensurate with the fees they were charged. Fairness means equal access as well as controlled access--ensuring that advertisers who pay more are more accessible than those who pay less.
  • Contracts are specifications that indicate the frequency of display of a given advertisement in response to relevant user queries.
  • Frequency-based These contracts specify the number of times a given advertisement is to be shown in response to the relevant user queries .
  • Ratio-based These contracts specify how often a given advertisement is to be shown in the prime space in response to the relevant user queries.
  • An ad A 1 can have a dependent contract of X% with another ad A,. The dependent contract will ensure that ad A ⁇ is shown together with A 3 at least X% of the times ad A-, will be shown.
  • Exclusive An ad A x can have an exclusive contract with another ad A . The exclusive contract will ensure that ad A will not be displayed along with ad A-.
  • WHILE primary space is not filled
  • P A denote the prime space contract value of Node A .
  • D (A, B, X) denote the dependency contract value from advertisement A to advertisement B [A should appear together with advertisement B, X% of the times advertisement B appears) .
  • E (A, B) denote the exclusive contract from advertisement A to advertisement B (note that no value is associated with exclusive contracts) . If a new advertisement A is to be introduced into the system with a prime space contract value of P A l a set of dependency contracts D (A, 1 , x) , . . . , D (A, k, y) and a set of exclusive contracts E (A, 1) , ... , E (A, g) , then for checking the consistency of all the contracts, the following basic checks have to be carried out (more specific checks may be required for specific algorithm ⁇ and their implementation ⁇ ) :
  • the consistency checking algorithm verifies if the new advertisement can be accommodated with the corresponding contract. If the new advertisement can be accommodated, the contract is approved and the system is updated to reflect the new addition, else, the consistency checking algorithm informs the advertiser of the maximal contract that can be accommodated for the new advertisement.
  • the fairness guarantees of an algorithm for the system ensures that the advertisements are displayed in a way that is proportional to the fee charged for that advertisement.
  • the fairness of the frequency-based contract algorithm, ratio-based contract algorithm, and the dependent contract algorithm follows from the probability distribution of the contract values and the random number generator that selects an advertisement with the correct random bias.
  • the probability that the random number generator will generate a number in a particular range is proportional to the length of the range. The larger the range, the more probable that a number corresponding to that range will be selected.
  • Each advertisement is assigned a range of values depending on the fee charged for that advertisement. The more the fee charged, the greater the range assigned to that advertisement. This ensures that the larger the fee, the more frequently (more number of times) that advertisement will be displayed.
  • Exclusive contracts are constraints imposed on the display of advertisements. Fairness in meeting the exclusive contracts means that the contracts are satisfied (no two advertisements that have an exclusive contract are displayed together) .
  • the prime space management algorithm 150 ensures that the exclusive contracts are met, by removing all the advertisements that have a relative contract with an advertisement A, as soon as advertisement A is selected for display in the prime space.
  • Story advertisement is a kind of advertisement in which the advertisement changes dynamically as time progresses.
  • the story advertisement is composed of a sequence of static conventional advertisements, which together tell a story.
  • a story advertisement is displayed using the notion of refresh-insert tags.
  • a refresh tag that is associated with a page denotes the time period after which the story advertisements are refreshed (the next advertisement in the sequence is displayed) . All other static advertisements are unaffected by the refresh timer.
  • the refresh tag can be set by the client or the application.
  • the story advertisement is a logical sequence of a number of advertisements, that will be displayed one at a time at each refresh cycle.

Abstract

Avec ce procédé et ce dispositif, un serveur disposant d'un ensemble de messages publicitaires est mis en communication électronique avec un réseau informatique. Les messages de ce serveur ne sont pas liés à une page particulière contenant des informations disponibles sur ce réseau, mais ils arrivent en réponse à une requête introduite par l'utilisateur (17) puis sont mélangés de façon dynamique avec le contenu des pages envoyées en réponse à cette requête (16). On peut ainsi afficher des pages de contenu assorties de messages publicitaires ciblés et spécifiques intégrés à une page, selon une disposition particulière. Ces messages peuvent être adaptés à une série de contraintes (19) demandées par l'utilisateur ainsi qu'à celles de l'éditeur de cette page. Ce dispositif fait appel à des contrats (21) précisant les règles de commercialisation (18) qui lient des messages publicitaires à des requêtes spécifiques, ce qui permet aux publicitaires de cibler un public précis et de garantir un certain degré de diffusion aux messages dans l'espace publicitaire le plus favorable. Des algorithmes permettent de contrôler la cohérence contractuelle, ce qui permet de veiller à ce que tous les contrats acceptés soient correctement appliqués. On décrit aussi une fonction d'affichage publicitaire pendant l'attente d'un téléchargement.
