In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating a configuration of a server device for search engine optimization according to an exemplary embodiment of the present invention. The server device 100 includes a device for optimizing a plurality of online contents included in a web site, Lt; / RTI >

1, the server apparatus 100 may include a site map generating unit 110, a site map registering unit 120, a searching unit 130, and a controller 140.

The site map generating unit 110 generates a site map for a plurality of online contents included in a website, and the site map is a list of pages constituting a web site, such as a user or a search robot A crawler may refer to a list of accessible pages of a website when using the website.

More specifically, the sitemap is a hierarchical list of web pages of a web site, showing the overall structure of the web site, and allowing the user or the search engine to search for the web page It can help.

On the other hand, the crawler is a software used in a site that operates a search engine to automatically search and index various information on a web (seb). It can be a spider, a robot, or an intelligent agent. Instead of people looking for information on websites, they constantly search for new web pages according to the pre-input method of computer programs, You can also use it to find new information and add indexes repeatedly.

For example, a search robot is mainly used in a search engine, collects necessary information while browsing web documents on the Internet, and indexes and arranges the information in a database.

A search robot used in the search engine searches web sites around the world and indexes related information in its database. Accordingly, most search engines on the Internet access a source of information and call it a search robot Agents are used.

More specifically, the search robot traverses a web server (HTTP Server) and follows a hypertext structure of the Web and recursively extracts another document referred to as a hyperlink from the corresponding HTML document. It can be a program that collects a lot of information on the homepage

The type of the search robot is a web robot (Googlebot) for a search engine, a MOM spider (EIT Link Verifier Robot) for searching for a database of HTML documents gathered in a hypertext structure by a web robot according to a search keyword on the Internet, Web site mirroring (HTMLgobble, GetUrl, WebCopy, WebFetcher), and web robot for collecting articles (NHN web robot).

On the other hand, the web site is not limited as long as it can provide contents through the Internet, such as a general online shopping mall, a news web site providing news articles, an internet portal site, a personal blog site, and a community web site of individuals.

In addition, the content may be a content composed of only one of text, image, and moving image, or may include text and image, text and moving image, or both.

The site map registration unit 120 can register information on the site map generated by the site map generation unit 110 in the access permission policy of the corresponding web site.

For example, a web site may have a robots.txt file, which is a text file in which an access permission policy for controlling crawling by a search robot is defined. The site map registration unit 120 registers a site created for online contents The map can be registered in the robots.txt.

When a search robot visits a website such as http://www.abc.co.kr/, it first calls http://www.abc.co.kr/robots.txt. Then, if a robots.txt file included in the root of the website is found, the search robot analyzes the contents of the robots.txt file and analyzes the contents of the robots.txt file. According to the information, only the content that can be collected is collected.

On the other hand, a website can only contain a single robots.txt file.

Hereinafter, the configuration of the robots.txt file will be described as an example.

For example, if a robots.txt file contains the following text, the Uniform Resource Locator (URL) blocks access to all routes for all search robots.

user-agent: * # Applies to all robots

disallow: / # Do not index all pages

On the other hand, a robots.txt file can contain one or more "disallow" fields, as shown below.

user-agent: Sets the robot that will not be allowed access.

disallow: Sets the list to disallow. If "disallow" is set to an empty value, all subpaths are accessible.

As described above, after the site map of the online contents included in the website is registered in the access permission policy of the corresponding website, the search unit 130 can perform the search using the address information of the online contents.

For example, after the site map of the online contents included in the website is registered in the robots.txt file and collected by the search robots used by the search engines, the search unit 130 searches the registered site maps Can be confirmed through the search using the URL of each of the online contents whether or not the online contents represented by the online contents are actually searched through the search engines.

Thereafter, the control unit 140 determines whether there is online content that is not searched among the online contents included in the web site according to the search result.

The site map generating unit 110 generates the site map information based on the generated online site map information or the access permission policy based on the information about the online content that is not searched, And the site map registering unit 120 can be controlled.

For example, under the control of the controller 140, the site map generator 110 may additionally generate a site map for the non-retrieved online contents, and the site map registering unit 120 may register the site You can add the URL of the map to your robots.txt file.

Alternatively, the site map generating unit 110 may further generate a site map for the online content that has not been searched for and add the site map to the previously generated site map, thereby replacing the site map itself.

Hereinafter, embodiments of a search engine optimization method according to the present invention will be described in detail with reference to FIGS. 2 to 8. FIG.

FIG. 2 is a flowchart illustrating a search engine optimization method according to an embodiment of the present invention. Referring to FIG. 2, a search engine optimization method according to an exemplary embodiment of the present invention is illustrated. We will explain it by helping. The description of the same components as those described with reference to FIG. 1 of the configuration shown in FIG. 2 will be omitted below.

Referring to FIG. 2, the site map generator 110 generates a site map for a plurality of online contents included in the web site (step S200).

For example, the site map generating unit 110 may generate the site map for each of the online contents so that only the information required to be provided to the search engine is included in the publisher operating the website.

For this purpose, the site map generating unit 110 selects only the information to be provided to the search engine among the contents included in the respective online contents, or excludes at least a part of the link information included in the online contents It is possible to limit the information included in the site map so that the robot does not collect unnecessary links and information related to the content.

3 to 5, a description will be made of an embodiment of a method of generating the site map by the site map generating unit 110 in step S200. First, the site map generating unit 110 generates a site map And perform indexing on the content to generate content indexing data as shown in FIG.

The indexing data may include at least one of a variety of information such as a content title, a content creation date, a content author, a content content, a content publishing URL, a content publishing web site name or organization, an image included in the content, .

The indexing data shown in FIG. 3 includes the content title (where the father is the mother, the reason why the children are pretty because of the mother gene), the date (2013-02-25), author (Kookmin Ilbo cookie news team) ), A URL (http://news.kukinews.com/article/view-), an agency (Kookmin Daily), a category (entertainment), and a keyword (where is Daddy).

Thereafter, the site map generating unit 110 extracts the main keywords from the generated indexing data, further extracts them as commercial keywords using the main keywords, summarizes the contents of the main keywords, You can configure a summary.

The site map generating unit 110 may extract the main keywords by assigning the scores differentially according to the following five conditions to the respective words extracted from the indexing data according to the morphological analysis algorithm.

The first condition grades the words differently depending on whether the words were extracted from the title or from the text. Generally speaking, the words in the title are more likely to be the main keywords, so the words extracted from the title are given higher scores than the words extracted from the text.

The second condition is to score a word at a position adjacent to the word when a word extracted from the title is found in the text or when a word extracted from the title is found in the text. In this case, the former can be given a higher score.

In the case of FIG. 3, for example, in the title of the article ['Where are my dad' and 'Why are my children pretty thanks to my mother's genes'], words such as dad, where, mama, . In addition, words adjacent to the main keywords extracted from the titles in the article content are sequentially searched and scores are given. In the example of Fig. 3, the process of finding the adjacent word of the keyword " mom " will be described. In the text of the present invention, several recent photographs have been uploaded under the heading ' , A search target keyword " mother " is found, and a predetermined number of adjacent words (e.g., two words) are searched for " mom " In this case, the phrase "Daddy is under the title of moms mimo" is extracted, and the words "dad", "somewhere" and "mom" in the two words preceding "mom" "And" title "are extracted and given a score.

The third condition grades according to the position in the text where the word exists. Depending on where the word is located within the text (less than the top 25% of the document size), mainte- nance (greater than 25% of the document size and less than 75%), and conclusion (over 75% of the document size) . In the preferred embodiment of the present invention, a higher score is given to the keyword located at the conclusion, but this can be adjusted according to the manner of development of the content. For example, in the case of a bold sentence, a higher score can be assigned to a word located in the introductory part.

The fourth condition is weighted according to the word frequency. The more frequent repetition of a word, the more important it is because it can be a high score, but if the frequency of a certain number of words more than a certain number of words, the content is rather a spam document is likely to give a reverse weight.

The fifth condition is that there exist a set of main keywords pre-classified as the main keywords of the category to which the content belongs, and in the case of the corresponding words or in the same word as the main keywords of other documents analyzed before the same date of the same category Score is given.

When the main keyword is extracted from the main content, the site map generation unit 110 further extracts the commercial keyword using the extracted main keyword. The commercial keyword may be determined as a parent concept of the extracted key keyword or a word that is closely related to the extracted keyword so that the content can be searched not only in the main keyword but also in the search process of the commercial keyword, To be included in the content.

For example, if key keywords such as " Lee Hyori, " " sexy ", and " dance " are extracted as main keywords, the site map generation unit 110 may extract a " diet " In this case, the content may include diet product advertisements, and may be exposed not only to users who search Lee Hyori, sexy, and dance, but also to users who search for diets.

In addition, when the keywords "Thailand" and "low cost airline" are extracted as the main keywords, commercial keywords such as "travel" and "Thailand hotel" can be extracted. However, &Quot; and " fall " are extracted together, words having a negative image of " falling " may be filtered so that the corresponding content is not included in the advertisement corresponding to the commercial keyword.

Meanwhile, the site map generating unit 110 may generate the site map using the indexing data, the main keyword, and the commercial keyword.

4 and 5 illustrate an example of a site map according to a preferred embodiment of the present invention. FIG. 4 shows a site map for content provided by a general site, and FIG. 5 shows a site map Respectively.

4 and 5, the site map may include information such as link information of original image data and moving image data, a news issuing organization, a news publication date, a main keyword, and a commercial keyword so that the search engine can utilize the site map have. The site map itself may be generated according to internationally standardized forms.

As described above, after the site map for the online contents included in the website is generated, the site map registration unit 120 registers the generated address of the site map in the robots.txt file of the website (step S210 ).

Referring to FIG. 6, the robots.txt file 10 of the web site "http://abc.co.kr " indicates whether or not permission / denial of certain search engines for the corresponding web site and permission / An access permission policy section 12 including information on the site map registration section 15 and a site map registration section 15 registered in the step S210.

On the other hand, when the user accesses the site map included in the site map registration part 15 of the robots.txt file 10 through a URL, which is address information, the xml file 20 ) May be displayed.

In FIG. 6, the robots.txt file 10 includes one site map URL. However, according to another embodiment of the present invention, two or more site maps are registered in the robots.txt file 10, URLs corresponding to the respective site maps may be included.

Referring to FIG. 7, the xml file 20 may include address information 22 for the search robot to collect the site map.

In this case, the search robots used by the search engines respectively use the robots.txt file 10 and the information in the xml file 20 as shown in Figs. 6 and 7, Maps can be collected.

Referring to FIG. 8, a site map according to an embodiment of the present invention can be generated in the form of an RSS feed. In this case, title, creation date, time and author information 31, images 33, text 35 and popularity / association article information 37, and the like.

When the site map generated in the form of an RSS feed as shown in FIG. 8 is applied to an RSS reader, users can easily receive information on online contents provided by the website in an RSS feed .

After the site map is registered in the robots.txt file and collected by the search robot, the search unit 130 performs a search using the URLs of the online contents included in the web site (step S220) .

For example, even if a site map for the online contents included in the website is generated and registered in the robots.txt file in steps S200 and S210, the specific online content may be mistakenly omitted or an error may occur in registration Due to various causes, some of the online content included in the website may not be retrieved by the URL.

The control unit 140 determines whether there is online content that is not searched among the online contents included in the web site according to the search result (S230).

If it is determined that there is an online content that is not searched, the site map generator 110 generates a site map for the online content that has not been searched at step S240, The address of the generated site map is added to the robots.txt file of the web site (step S250).

The method of generating a site map for the online content that has not been searched in step S240 may be the same as the method of generating the site map in step S200, so a detailed description thereof will be omitted.

Meanwhile, the site map of the robots.txt file 2 or more can be registered by adding the address of the site map that is generated in step S250 to the robots.txt file.

In this case, the first registered site map is generated in accordance with the latest data on the online contents of the web site in a preset time period (for example, 2 to 5 minutes), and the second registered site map is a URL And may be generated using data on the missing content according to the online content search result.

FIG. 9 is a flowchart illustrating another embodiment of a search engine optimization method according to the present invention. A description of the same steps as those described with reference to FIGS. 1 to 8, among the steps shown in FIG. 9, .

9, the site map generating unit 110 generates a site map for a plurality of online contents included in the website (S900), and the site map registering unit 120 searches the generated site map And registers it in the webmaster tool of the engine (step S910).

For example, since the webmaster tool form may be different for each of the plurality of search engines 1010 to 1050, the site map generating unit 110 of the server apparatus 100 may generate a plurality of search engines 1010 to 1050 A site map may be generated for each search engine according to the webmaster tool form of FIG. (See Fig. 10)

Thereafter, the search unit 130 searches for the URLs of the online contents included in the web site (S920).

For example, even if the site map of the online contents in the webmaster tool of the search engine is registered in step S910, it is determined that the corresponding online contents are not registered Some of the online content included in the website may not be retrieved by the URL.

In operation S930, the control unit 140 determines whether there is online content that is not searched from the online contents included in the web site according to the search result.

If it is determined that the online contents are not searched, the site map generating unit 110 generates a site map for the online contents that have not been searched (S940) The generated site map is additionally registered in the web master tool of the search engine (step S950).

According to another embodiment of the present invention, the server apparatus 100 transmits a user interface (UI) for displaying information on the search result obtained in step S220 or step S920 to a user's terminal (not shown) .

11 shows an example of a user interface for displaying search results for online contents.

Referring to FIG. 11, a user interface for providing RSS collection monitoring results for search engine optimization (SEO) management may be provided to a user terminal.

The user interface includes a first information window 1100 including date and time search result information for a specific web site, a second information window 1150 including RSS information for each online content collected according to the search result, .

For example, in the first information window 1100, the number of articles collected, the number of indexing checks, the number of Google indexes, the number of times of body collection, and the number of images collected in the last week and the last hour / May be included.

In the second information window 1150, an RSS title, a title, a creation date, a collection date, a check date, a Google index, an author URL, an URL, and a URL for each online content of the corresponding web site, May be included.
