Abstract

A method and system for creating a search result list, which can simplify a system configuration by searching a single database for search information, and also can display search information on a plurality of display areas with only one keyword purchase. According to the present invention, there may be provided a method and system for creating a search result list, which can differ from a conventional method and system of providing an individual database for each of display areas and thereby effectively managing search information, and can enroll a keyword in a single database according to one keyword purchase and thereby display search information on a plurality of display areas.

Claims

1. A computer-implemented method of creating a search result list, the method comprising the steps of:

maintaining a database, the database storing search information in association with at least one keyword, each search information being associated with an advertiser, the search information including a search result list and a rank index information wherein the rank index information is determined based, at least in part, upon a bid amount received from an advertiser;

searching the database for search information corresponding to a keyword in response to a search request received from a searcher;

identifying search information having keywords generating a match with the search request;

classifying at least one of the identified search information into one of a plurality of area groups by using the rank index information;

creating a search result list by arranging the classified search information for display as the search result list according to a predetermined rule; and

displaying the search result list in response to the search request, the search result list including at least one search listing of the sorted search information, wherein each of the plurality of area groups are displayed separately from each other.

2. The method of claim 1, wherein

a plurality of search result lists are created for the plurality of the area groups and the plurality of search results are simultaneously displayed on a display area allocated to each area group.

3. The method of claim 2, wherein the step of simultaneously displaying comprises the step of:

charging an advertiser of the search information with an advertising fee when the searcher clicks the displayed search listing of the search result list, and

the advertising fee is calculated by using a maximum click cost entered from the advertiser.

5. The method of claim 2, wherein the classified search information in at least one of the area groups is arranged in a random order.

6. The method of claim 2, wherein the classified search information in at least one of the area groups is arranged according to a predetermined sorting rule.

7. The method of claim 6, wherein the predetermined sorting rule is created by considering at least one of a popularity of the search information and a relation between the search information and the keyword.

8. The method of claim 2, wherein the classified search information in at least one of the area groups is arranged in a random order and the classified search information in at least one of the area groups is arranged according to a predetermined sorting rule.

9. The method of claim 1, wherein the step of classifying comprises the steps of:

classifying the identified search information within a first predetermined range of the ranks into a first area group; and

classifying the identified search information within a second predetermined range of the ranks into a second area group, wherein the second area group is displayed separately from the first area group.

10. The method of claim 1, wherein the rank index information is click choice index (CCI) information and the CCI information is determined based, at least in part, upon the bid amount and at least one of an average click rate and a click through rate (CTR) for a predetermined time period with respect to the search information, wherein the click rate is calculated by dividing the number of clicks by the number of displays.

11. The method of claim 1, further comprising the step of updating the CCI information stored in the database.

12. The method of claim 1, further comprising the steps of:

determining price ranges of the bid amount, which allows the search information to be classified into each area group for display; and

providing the price ranges in association with each of the area groups to advertisers.

13. A computer-readable recording medium storing a program for implementing the method recited in claim 1.

14. A system for creating a search result list, the system comprising:

a database for storing search information in association with at least one keyword, each search information being associated with an advertiser, the search information including a search result list and a rank index information wherein the rank index information is determined based, at least in part, upon a bid amount received from an advertiser;

a search component configured to search the database for search information of a keyword corresponding to a keyword in response to a search request received from a searcher;

a group classifier configured to classify at least one of the searched search information into one of a plurality of area groups by using the rank index information; and

a list creator configured to create the search result list by arranging the classified search information for display as the search result list according to a predetermined rule.

15. The method of claim 14, wherein

a plurality of search result lists are created for the plurality of the area groups and the plurality of search results are simultaneously displayed on a display area allocated to each area group.

16. The method of claim 14, wherein the searched search information within a first predetermined range of the ranks is classified into a first area group and the searched search information within a second predetermined range of the ranks is classified into a second area group, wherein the second area group is displayed separately from the first area group.

17. The method of claim 14, wherein the rank index information is click choice index (CCI) information and the CCI information is determined based, at least in part, upon the bid amount and at least one of an average click rate and a click through rate (CTR) for a predetermined time period with respect to the search information, wherein the click rate is calculated by dividing the number of clicks by the number of displays.

18. The method of claim 17, wherein the stored CCI information is updated periodically.

19. The method of claim 14, wherein the classified search information in at least one of the area groups is arranged in a random order.

20. The method of claim 14, wherein the classified search information in at least one of the area groups is arranged according to a predetermined sorting rule.
