DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a search advertisement model, and provides a UI environment for exposing a site list and a product list together as a search result for a keyword, and in particular, to provide a search advertisement system and method for allocating the exposure of a product advertisement. do.

1 is a block diagram illustrating an internal configuration of a search advertisement system according to an exemplary embodiment. As shown in FIG. 1, the search advertisement system 100 according to an exemplary embodiment may include and be configured to include an exposure unit 110, a determination unit 120, and a calculation unit 130.

The exposure unit 110 may expose an advertiser's site list and a product list together as a search result for a keyword. In the present specification, the site may mean an internet mall operated by an advertiser, and a product may mean an object sold or traded on an advertiser's site.

Referring to FIG. 2, a page for providing a search result (hereinafter, referred to as a search result page) includes an area for exposing an advertisement list corresponding to a search result in the first area 210 and the second area 220. It can be divided into. In this case, a site list related to a keyword may be arranged and exposed in the first area 210, and a product list related to the keyword may be arranged and exposed in the second area 220. That is, the exposure unit 110 may simultaneously expose the first area 210 in which the site list is arranged and the second area 220 in which the product list is arranged on the search result page.

FIG. 2 is an example screen of a search result page in which the first area and the second area are exposed together, and the screen configuration of the search result page may be changed.

In the present embodiment, the advertisement list exposed in the first area 210 and the second area 220 may be selected based on different criteria. In addition, the advertisement list exposed in the second area 220 may be selected by the advertisement list exposed in the first area 210. For example, the exposure unit 110 exposes a product list consisting of products of sites exposed in the first area 210 to the second area 220 or when a user selects a specific site in the first area 210. The list of products of the site selected by the user may be exposed in the second area 220.

In the present embodiment, the bid for the keyword may basically receive a site bid from the advertiser, and may additionally receive a product bid determined independently or subordinately to the site bid. In particular, the exposure unit 110 may be arranged on the first area 210 according to the exposure order in the case of the site list, and may be arranged on the second area 220 according to the exposure amount in the case of the product list. In this case, the exposure ranking of the first area 210 and the exposure amount of the second area 220 may be determined based on the bid amount presented by the advertiser at the time of bidding.

The determiner 120 may determine an exposure ranking (ie, site ranking) that is exposed in the first region based on the bid amount of the advertiser with respect to the site list provided as a search result for the keyword. In particular, the determination unit 120 may determine the exposure amount exposed to the second area based on the bid amount of the advertiser with respect to the product list provided as a search result for the keyword. In other words, the advertiser bid amount affects the exposure ranking of the first area, and further affects the exposure amount of the default page of the second area. At this time, the determination unit 120 may determine the exposure ranking of the first area and the exposure amount of the second area based on at least one bid amount of the site bid amount and the product bid amount. Basically, the site bid amount may affect the exposure amount of the second area, but further, the bid amount per product may also affect the exposure amount of the second area. In this case, the product bid amount inherits the site bid amount as it is (site bid = product bid), or inherits the site bid amount, but the advertiser can modify each product bid amount (site bid <> product bid). Here, the bid amount affecting the exposure ranking of the first area and the exposure amount of the second area may mean a bid amount of a cost per click (CPC) method. In some cases, the bid amount of the cost per action (CPA) method may be considered in determining the exposure rank of the first area and the exposure amount of the second area.

For example, the determination unit 120 may distribute the exposure amount of a predetermined unit period (eg, 1 day, 1 week, etc.) at a ratio corresponding to the bid amount for each advertiser. That is, the determination unit 120 may distribute the total exposure amount within the unit period with respect to the second area based on the bid amount. For example, referring to FIG. 3, when the bid amounts of advertisers A, B, and C are 100, 200, and 300 won, the total exposure amount may be distributed as 1: 2: 3 for advertisers A, B, and C. In this case, an advertisement list consisting of one advertiser's products is exposed in one exposure of the second area, and when advertiser A's product list is exposed once during a unit period, advertiser B's product list is twice and advertiser C's product is exposed. The list is exposed three times.

As another example, the determination unit 120 may distribute the size of the exposure area as the exposure amount in a ratio corresponding to the bid amount per advertiser for one exposure. In this case, the size of the exposure area may be implemented by at least one of the number of product advertisements exposed, the size of the product advertisement, and the amount of information of the product advertisement. That is, the determination unit 120 may distribute the exposure amount at the time of exposing the second area based on the bid amount. For example, referring to FIG. 4, when the bid amounts of advertisers A, B, and C are 100 won, 200 won, and 300 won, respectively, the size of the exposed area may be distributed as 1: 2: 3 to advertisers A, B, and C. In this case, as shown in FIG. 4, all of the products of advertisers A, B, and C are exposed to one exposure of the second area, and when the product of advertiser A is exposed, two items of advertiser B are displayed. Advertiser C's three products may be exposed. Meanwhile, referring to FIG. 5, when the bid amounts of advertisers A, B, and C are 100 won, 100 won, and 200 won, respectively, the size of the exposed area may be allocated to the advertisers A, B, and C at 1: 1: 2. In this case, as shown in FIG. 5, the products of advertisers A, B, and C are exposed one by one for each exposure of the second area, and the area size of the products of advertiser C is exposed twice as much as that of advertiser A and advertiser B. Can be assigned by size. In addition, as shown in FIG. 6, when the products of advertisers A and B are exposed one by one while allocating the area where the products of advertiser C are exposed to twice the size of advertisers A and B, the two products of advertiser C are exposed. The dosage can be distributed in the form of That is, in the case of FIG. 6, the number of advertisements exposed at the same time may be changed while the space itself is changed in allocating the exposure amount of the second area.

3 to 6 are exemplary screens of a method of allocating the exposure amount of the second area, and the present invention is not limited thereto. The method and shape of the exposure ratio of the page of the second area may be changed.

Accordingly, the exposure unit 110 arranges the site list in the first area according to the exposure ranking determined based on the bid amount, and simultaneously arranges the product list in the second area according to the exposure amount determined based on the bid amount, thereby searching for the keyword. The first area and the second area may be exposed together on the UI that provides the.

In another embodiment, a ranking index (RI) may be used to determine the exposure ranking of the first region and the exposure amount of the second region.

The calculation unit 130 calculates a ranking index for the site list and / or the product list. In this case, the ranking index may be calculated in consideration of the quality index in addition to the bid amount for the keyword. Here, the quality index may be generated in at least one of a site quality score and a product quality score and may be considered in calculating the ranking index.

7 is an example for explaining the method of calculating the rank index.

As shown in FIG. 7, the calculation unit 130 may calculate the ranking index 701 using the maximum bid amount 702 and the quality index 703. In detail, the calculation unit 130 assigns a first weight value and a second weight value to the maximum bid amount 702 and the quality index 703 to calculate the ranking index 701, respectively, and the first weight value and the second weight value are respectively set. The weighted maximum bid amount 702 and the quality index 703 may be calculated. For example, the rank index 701 may be expressed as Equation 1 below.

[Equation 1]

Rank index = (first weight * maximum bid) * (second weight * quality index)

Here, the maximum bid amount 702 may mean the maximum cost that the advertiser of the advertisement is willing to pay when the advertisement (site and / or product) registered in the keyword is clicked, at least one of the site bid amount and the product bid amount It may include.

In addition, the quality index 703 is calculated based on the click-through rate (CTR) 704, and indicates a site quality index indicating a click response to a list of users and a click response to a product list of users. It may include at least one of the product quality index. For example, the quality index 703 may be expressed as Equation 2 below.

&Quot; (2) &quot;

Quality Index = (Third Weight * Total Click Response) · (Fourth Weight * Duration)

As another example, in order to calculate the quality index 703, the click response of the site list, the product click response at the default exposure, and the product click response at the click response of the site list are subdivided and given different weights. In addition to site listings, location premiums can be reflected within product listings.

As described above, the calculation unit 130 may calculate the ranking index in consideration of the quality index together with the bid amount. In order to calculate the ranking index, in addition to the above-described methods, one or more of the known ranking techniques may be utilized.

Accordingly, the determiner 120 may determine the exposure rank of the first area and the exposure amount of the second area according to the ranking index. For example, the product exposure amount in the second region is equal to (RI / ∑ (RI)), where RI is a ranking index, and a higher ranking index has a higher ratio in the exposure of the second region. In addition, the determination unit 120 may equally distribute the product exposure in the second region to 1 / n, or may distribute in various ways using a Fibonacci sequence or the like.

The exposure unit 110 may arrange the site list in the first area according to the exposure ranking determined based on the ranking index, and arrange the product list in the second area according to the exposure amount determined based on the ranking index. In this case, the exposure unit 110 arranges the product list on the second area according to a predetermined exposure amount, and exposes additional information to a product advertisement having a rank index of a predetermined rank or more or a predetermined number of product advertisements having a high rank index. can do. For example, in the second region, additional additional information may be further exposed to a corresponding product advertisement by displaying information indicating that the product has a high ranking or adding an information amount of the exposed advertisement.

According to the above configuration, when the site list of the first area and the product list of the second area are exposed together as a search result for the keyword, the exposure amount of the first area as well as the exposure amount of the second area are based on the advertiser bid amount. You can decide to expose a list of products along with a list of sites.

8 is a flowchart illustrating a search advertisement method of exposing a product advertisement by allocating an exposure amount according to an embodiment of the present invention. In the search advertisement method according to an embodiment, each step may be performed by the search advertisement system described with reference to FIG. 1.

First, a search advertisement system may receive a site bid from an advertiser for a keyword and additionally receive a product bid determined independently or subordinately to a site bid. The search advertisement system may inherit the site bid amount in the case of the product bid amount according to the bid type (site bid = product bid), or may inherit the site bid amount but the advertiser may modify each product bid amount (site bid <> product bid). Bidding for a keyword is basically made of a bid per click (CPC) method, and in some cases, a bid per cost (CPA) method is also possible.

In operation 810, when the search advertisement system exposes the advertiser's site list and the product list together as a search result for the keyword, the search advertisement system may determine the exposure ranking of the site list and the exposure amount of the product list based on the bid amount for the corresponding keyword. . In other words, the bid amount of the advertiser for the keyword affects the exposure ranking of the site list, and moreover, the impression amount on the default page of the product list. In this case, the search advertisement system may determine the exposure ranking of the site list and the exposure amount of the product list based on at least one bid amount of the site bid amount and the product bid amount.

In operation 820, the search advertisement system may expose the list of products of the advertiser and the list of products as a search result for the keyword. In this case, the search result page may be divided into a first area and a second area to expose an advertisement list corresponding to the search result. In the first region, a list of sites related to a keyword may be exposed, and a list of products related to the keyword may be exposed in a second region. That is, the search advertisement system may simultaneously expose the first area where the site list is arranged and the second area where the product list is arranged on the search result page. Here, the advertisement list exposed in the first area and the second area may be selected based on different separate criteria, or the advertisement list exposed in the second area may be selected by the advertisement list exposed in the first area. For example, the search advertisement system may expose a product list consisting of products of sites exposed in the first area to the second area, or may generate a product list of the site selected by the user when the user selects a specific site in the first area. It can be exposed to two areas.

In particular, in operation 820, the search advertisement system may be arranged on the first area according to the exposure order in the case of the site list, and may be arranged on the second area according to the exposure amount in the case of the product list. In this case, the exposure ranking of the first area and the exposure amount of the second area may be determined based on the bid amount of the advertiser for the keyword through step 810.

For example, the search advertisement system may distribute the total exposure of a certain unit period (eg, 1 day, 1 week, etc.) at a ratio corresponding to the bid amount for each advertiser. For example, the search advertisement system may allocate the total exposure amount to 1: 2: 3 for advertisers A, B, and C when the bid amounts of advertisers A, B, and C are 100, 200, and 300 won, respectively. In this case, an advertisement list consisting of one advertiser's products is exposed in one exposure of the second area, and when advertiser A's product list is exposed once during a unit period, advertiser B's product list is twice and advertiser C's product is exposed. The list may be exposed three times.

As another example, the search advertisement system may allocate the size of the exposure area as the exposure amount in a ratio corresponding to the bid amount per advertiser for one exposure. In this case, the size of the exposure area may be determined by at least one of the number of product advertisements exposed, the size of the product advertisement, and the amount of information of the product advertisement. That is, the search advertisement system may distribute the exposure amount at the time of one exposure to the second area based on the bid amount. For example, the search advertisement system may allocate the size of the exposure area 1: 1: 2 to advertisers A, B, and C when the bid amounts of advertisers A, B, and C are 100, 100, and 200 won, respectively. In this case, the search advertisement system exposes the products of advertisers A, B, and C to the same size for one exposure of the second area, but when one of the products of advertiser A and advertiser B is exposed, You can expose two. Alternatively, the search advertising system exposes the products of advertisers A, B, and C one by one for each impression in the second area, but doubles the size of the area where the products of advertiser C are exposed compared to advertisers A and B. Can be assigned as In another form, the search ad system exposes two items of advertiser C when each of the items of advertisers A and B is exposed, while assigning an area in which advertiser C's products are exposed to twice the size of advertiser A and advertiser B. The dosage can be distributed in the

Furthermore, the search advertisement system may determine the exposure ranking of the first area and the exposure amount of the second area based on the ranking index for the site list and / or the product list. In this case, the search advertisement system may calculate the ranking index using the maximum bid amount and the quality index. Here, the maximum bid amount may mean a maximum cost that the advertiser of the advertisement is willing to pay when the advertisement (site and / or product) registered in the keyword is clicked, and may include at least one of a site bid amount and a product bid amount. Can be. The quality index is calculated based on a click-through rate (CTR), and includes at least one of a site quality index indicating a click response to a list of users and a product quality index indicating a click response to a list of products. It may include.

Accordingly, the search advertisement system may arrange the site list in the first area according to the exposure ranking determined based on the ranking index, and arrange the product list in the second area according to the exposure amount determined based on the ranking index. In this case, the search advertisement system arranges the product list according to a predetermined exposure amount in the second area, and may expose additional information about a product advertisement having a rank index of a predetermined rank or higher or a predetermined number of product advertisements having a high rank index. have. For example, in the second region, additional additional information may be further exposed to a corresponding product advertisement by displaying information indicating that the product has a high ranking or adding an information amount of an exposed advertisement.

As described above, when the site list of the first area and the product list of the second area are exposed together as a search result for the keyword, the advertiser bid amount for the keyword affects the exposure ranking of the first area. May affect the exposure of the area. In this case, the distribution of exposure amount for the second area may be exposed by allocating a predetermined unit of exposure amount by a bid amount ratio, or by exposing the size of the exposed area by a bid amount ratio in one exposure. In addition, the advertiser bid amount for the keyword may be reflected in the ranking index, and the search advertisement may be exposed by determining the exposure rank of the first area and the exposure amount of the second area by using the ranking index.

Thus, according to an embodiment of the present invention, by providing a UI environment that exposes a site list and a product list together as a search result for a keyword, it is possible to implement a new search method search advertising model and to improve the quality of the search result of the keyword. Can be improved. In addition, according to an exemplary embodiment of the present invention, when the site list and the product list are exposed together, the exposure amount may be distributed to the product list to increase the user's attention and increase the advertisement effect. Furthermore, according to an embodiment of the present invention, by determining the exposure amount of the advertisement based on the bid amount or the ranking index for the keyword, it is possible to further improve the advertisement effect of the advertiser due to the effective exposure ratio of the advertisement.

The methods according to embodiments of the present invention may be implemented in the form of a program instruction that can be executed through various computer systems and recorded in a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination.
