BACKGROUND1. Field of the Invention
The present invention relates generally to online advertising, and more particularly to display of online advertisements.
2. Description of Related Art
A search engine may allow users to search for web pages or other materials accessible over the Internet with one or more search terms. After receiving from a user a search request including one or more search terms, a search engine may parse the search term(s) from the search request, identify web pages that may be related to the search term(s), and display on a result page information about the web pages as a list of search results, e.g., a link to a web page containing the search term(s). The search results may be ranked according to their relevance to the search terms, with the most relevant search result being positioned at the top of the list. The relevance may be determined according to search engine algorithms of a search engine service provider.
The search engine service provider may also display advertisements as a separate list on a result page displaying the search results. The search engine service provider may sign contracts with a number of advertisers (e.g., Macy's™., and GM™.), and display a link to an advertiser's website when a search term in a search request is related to the advertiser's products or services. For example, when the search terms include “camera,” a list of relevant search results may be displayed at one portion of a result page, and a list of advertisements may be displayed at another portion of the result page. An advertisement may include some brief information about a camera manufacturer or a camera store, and a link to its website. An advertiser may be charged according to the number of clicks on its link (Pay Per Click) or the number of times its advertisement is displayed (Pay Per Impression). Since the advertisements are related to the search term(s) of a search request, it is more likely that the user will be interested in the advertisements, and in this way advertising may be better targeted at users.
The list of relevant search results may take up a number of result pages, and each result page may expand over several screens. However, the list of advertisements may be shorter than a screen. Some currently available solutions start to display the list of advertisements from the top of a result page. The position of the advertisement list is fixed and static. When a user scrolls down to look at search results at a lower portion of a result page, the upper portion of the result page, including the advertisements, may move off the current screen and may not be visible to the user anymore. Advertisers may lose advertising opportunities and the search engine service provider may lose revenue.
Therefore, it may be desirable to provide a system and method which may help to improve the efficiency of online advertising.

DETAILED DESCRIPTIONThe present invention provides a system and method for increasing display time of online advertisements. Upon receiving a search request including one or more search terms, a search engine may identify a list of search results and display the search results on one side of a result page. The search engine may also obtain a list of advertisements and display the list of advertisements on the other side of the result page. When a user scrolls down to look at search results at a lower portion of the result page, the list of advertisements may be moved down, following the movement of the screen, so that at least a part of the list of advertisements may keep being displayed on the current screen. Since the online advertisements are visible to the user for a longer time, there are more opportunities for the online advertisements to get the user's attention, and consequently more opportunities for the user to click on an advertisement. As a result, the efficiency of online advertising may be improved. The invention may be carried out by computer-executable instructions, such as program modules. Advantages of the present invention will become apparent from the following detailed description.
FIG. 1 illustrates an online advertising system in which a system of the present invention may be used. As shown, a number of user terminals102-1,102-2, . . .102-nmay communicate with adata server101 over acomputer network103, and thedata server101 may access anadvertisement database104.
Thedata server101 may be a computer system, including a central processing unit (CPU)1011, amemory1012, an interface1013 to external storage devices, aninterface1014 to the Internet, auser interface1015, etc. All of these elements may be interconnected by asystem bus1016. Alternatively, thedata server101 may include multiple computer systems each configured to accomplish certain tasks and coordinate with other computer systems to perform the method of the present invention.
TheCPU1011 may control thedata server101 to carry out a number of processes, including but not limited to the one described below with reference toFIG. 3. The processes may be stored in thememory1012. In one example, theCPU1011 may receive a search request over thecomputer network103, parse one or more search term(s) from the search request, identify web pages relevant to the search term(s), determine relevance of the web pages to the search terms, rank the web pages, and generate a result page with the web pages being displayed as a list of search results at one part of the result page, e.g., the left side.
Thedata server101 may also access theadvertisement database104 via the interface1013 to obtain advertisements relevant to the search term(s), rank the advertisements (e.g., according to the service fee rates) and display the advertisements as a list of advertisements on another part of the result page, e.g., the right side.
The user terminals102-1,102-2, . . .102-nmay be a desktop computer, a laptop computer, a personal digital assistant (PDA), a smartphone, a set top box or any electronic devices having access to thecomputer network103. A user terminal may have aCPU1021, amemory1022, auser interface1023, aninterface1024 to the Internet, adisplay controller1025 and adisplay1026, interconnected via abus1027. The user terminal may also have a browser application configured to receive and display web pages, which may include text, graphics, multimedia, etc. The web pages may be based on, e.g., Hypertext Markup Language (HTML) or extensible markup language (XML).
Theadvertisement database104 may store information about a number of advertisers which have contracts with a search engine service provider running thedata server101. The information about an advertiser may include, e.g., one or more keywords about its products or services, the service fee for a click (Pay Per Click) or an impression (Pay Per Impression), the expiration date of its contract with the search engine service provider, and the billing information. Although theadvertisement database104 is shown as a device external to thedata server101, it should be understood that information about advertisers may be saved in an internal memory device in thedata server101.
Thecomputer network103 may be, e.g., the Internet. Network connectivity may be wired or wireless, using one or more communications protocols, as will be known to those of ordinary skill in the art.
FIG. 2A illustrates a system for presenting online advertisements according to one embodiment of the present invention.
Ascreen control module201 may be installed in thedata server101. Thescreen control module201 may be a program stored in thememory1012. After a result page, including a list of search results on its left side and a list of advertisements on its right side, is generated and displayed to a user, thescreen control module201 may detect the part of the result page that is un the currently displayed screen, and move at least a part of the list of advertisements into the currently displayed screen. In one embodiment, the top of the advertisement list may be aligned with the top of the screen, so that the first advertisement in the list may always be displayed at the upper right corner of the screen, no matter whether the user is scrolling down, scrolling up, or looking at a certain part of the result page.
In one embodiment, thescreen control module201 may repeat the advertisement list in cycles, so that each advertisement in the list may have substantially equal opportunities for being displayed on the screen and the part of the result page for advertisements are almost always filled. The advertisement list and its copies may be statically displayed on the result page till the end of the result page or being filled in on the fly.
In one embodiment, instead of repeating the list of the advertisements generated according to the search terms, thescreen control module201 may interact with theCPU1011 and determine the user's interest according to parts of the result page which the user has moused over or clicked on, and dynamically generate an updated advertisement list fine tuned to the user's interest and display the updated advertisement list on the screen. The details about generating and displaying an updated advertisement list fine tuned to a user's interest are described in the co-pending U.S. patent application Ser. No. 12/187,324, entitled Method and System for Dynamically Updating Online Advertisements, which is incorporated herein by reference in its entirety.
FIG. 2B illustrates a system for displaying online advertisements according to one embodiment of the present invention. Instead of being installed in thedata server101, ascreen control module202 may be installed in a user terminal102n,and may interact with aCPU1021 and adisplay controller1025 of the user terminal102nto enable at least a part of the advertisement list to be displayed on the currently displayed screen. Thescreen control module202 may be a program stored in amemory1022 in the user terminal102n.
It should be understood that thescreen control module202 inFIG. 2B, as well as thescreen control module201 inFIG. 2A, may be accomplished by hardware or firmware as well.
FIG. 3 illustrates a flow chart of a method for presenting online advertisements according to one embodiment of the present invention. The method may be used with the systems shown inFIGS. 2A and 2B.
At301, thedata server101 may receive a search request from a user terminal102n.The search request may include one or more search terms.
At302, thedata server101, or some portion thereof such as theCPU1011, alone or in conjunction with other elements of theserver101, may parse the search request and abstract the one or more search terms.
At303, thedata server101 may search the Internet to identify web pages which may contain the search terms or may be relevant to the search terms.
At304, thedata server101 may determine the relevance of the web pages using one or more algorithms.
At305, thedata server101 may rank the web pages according to their relevance.
At306, thedata server101 may search theadvertisement database104 to obtain advertisements relevant to the search terms.
At307, thedata server101 may rank the advertisements according to, e.g., service fee rates.
At308, thedata server101 may send data to the user terminal102n,so that the user terminal102nmay present on its display1026 a list of search results and a list of advertisements on one or more result pages. The list of search results may include information about the relevant web pages. In one example, a result page may have a left column for displaying the list of search results, starting from the most relevant search result, and a right column for displaying the list of advertisements, starting from the advertisement with the highest service fee rate. The list of search results may expand over a number of result pages, and a result page may be longer than a screen.
In another example, the list of search results may be displayed in a right column of the result page, and the list of advertisements may be displayed in a left column of the result page.
At309, thescreen control module201 or202 may determine the currently displayed screen.
At310, thescreen control module201 or202 may determine whether the right column of the currently displayed screen, which is used to display advertisements, is available to display more advertisements. if not, the process may return to309.
Otherwise, at311, thescreen control module201 or202 may display at least a part of the advertisement list in the right column of the currently displayed page.
In one embodiment, the top of the list of advertisements may be aligned with the top of the currently displayed screen, so that the first advertisement in the list of advertisements may almost always be displayed at the upper right corner of the currently displayed screen.
In one embodiment, thescreen control module201 or202 may repeat the advertisement list in cycles, so that the first line of the advertisement list will follow the last line of the advertisement list. The advertisement list and its copies may be statically displayed on the result page until the end of the result page, or be dynamically filled in the currently displayed screen when the user scrolls up and down the result page.
In one embodiment, an updated advertisement list may be generated and displayed in the right column of the currently displayed screen. The updated advertisement list may be fine tuned to the user's interest according to parts of the result page the user has clicked on or moused over. The updated advertisement list may be different from the advertisement list generated at308 in, e.g., the advertisements displayed or their order. The method of generating and displaying an updated advertisement list fine tuned to a user's interest is described in the co-pending U.S. patent application Ser. No. 12/187,324, entitled Method and System for Dynamically Updating Online Advertisements, which is incorporated herein by reference in its entirety.
