Abstract: A content provider can provide content, such as advertisements or other promotional material, to a recipient. A distribution system of the content provider can receive a query and select one or more advertisements and a user interface for presenting the advertisements based on the query, information associated with the user, a set of queries received from the user, and/or other information. A model for selecting the user interface can be generated by serving available user interfaces randomly or pseudo-randomly and monitoring user interaction with the served user interfaces. The model can be updated during regular use based on the performance of the user interfaces.

Abstract: A content provider can provide content, such as advertisements or other promotional material, for display by a mobile application. As contextual information is typically limited for mobile applications, the content provider can use other information in addition to or in place of contextual information to select advertisements. This information can include location information, user activity with regards to the mobile application, information regarding a recipient of the advertisement, such as demographic information, information regarding the mobile application, such as information regarding the type of mobile application, and product inventory information. A user profile also may be used to select advertisements. The user profile can include a set of merchants and merchant types, for example clothing retailers, to which a user may be more responsive. The user profiles can be generated and updated by logging merchants that the user visits or interacts with via advertisements.

Abstract: A system includes an application programming interface, an indexer, a security unit and at least one search engine. The application programming interface uploads user-selected custom content from a first user. The indexer indexes the custom content to produce a first search index. The security unit authenticates a user and the at least one search engine receives a search query from the user, searches the first search index based on the search query, and searches a second search index based on the search query and based on results of the user authentication, where the second search index is different than the first search index.

Abstract: A system searches a first search index based on a search query to obtain first search results and searches a second search index based on the search query to obtain second search results. The system further ranks the first search results using a first ranking algorithm and one or more first ranking parameters to produce ranked first search results, and ranks the second search results using a second ranking algorithm and one or more second ranking parameters to produce second search results, where the one or more first ranking parameters are different than the one or more second ranking parameters and where the one or more second ranking parameters include at least one of previous user feedback associated with custom content that corresponds to the second search index, annotations of the custom content provided by a user, or usage patterns associated with users previously accessing and searching the custom content. The system also provides the ranked first and second search results to a user.

Abstract: A method of automatic redemption of manufacturer offers comprises a loyalty card account linked to a remote offer redemption system. Manufacturers send offers to the remote system, wherein each offer comprises redemption rules and discount information. The user selects and saves offers to his remote system account and presents the loyalty account information to the merchant when making a purchase. The user's loyalty account information causes the transaction details to be forwarded to the merchant's loyalty backend, which determines that the user is registered with the remote system and forwards the transaction details to the remote system. The transaction details are analyzed to determine if the user has an offer that meets the redemption rules. If the user has an applicable saved offer, the offer is redeemed. The offer is marked as “redeemed,” and the user is notified of the redemption.

Abstract: Methods, systems, and computer program products are provided for tracking user interactions with interfaces and determining social data. One example method includes receiving from an entity an indication of interfaces that are used to interact with users, registering the user interfaces, tracking user interaction with the interfaces, and using the tracking information to determine all actions associated with a given user that are to be attributed to the entity.

Abstract: A system includes a server to store content and a content searching system. The content search system includes an application programming interface to receive user-selected metadata uploaded from a first user, where the metadata includes data that describes content stored at a server. The content searching system further includes an indexer to index the metadata to produce a metadata search index, a search engine to search the metadata search index based on a search query received from a user to produce metadata search results, and a delivery engine to send the metadata search results, and a link to the remote server, to the user to permit the user to access the content stored at the remote server.

Abstract: A system may receive selection of one or more of a set of custom content groups, where each of the custom content groups is associated with a custom search index that is different from a web search index and a custom search index associated with another one of the custom content groups. The system may receive a search query from a user, perform a search of the web search index based on the search query to identify web search results, perform a search of one or more custom search indexes associated with the selected one or more the custom content groups to identify custom search results, generate a search result document that includes the web search results and the custom search results; and provide the search result document.

Abstract: A system may store information regarding a set of items of content, receive sample content from a user, determine whether the sample content matches content of one or more of the items of content, and notify the user whether the sample content matches one or more of the items of content without identifying the one or more items of content to the user.
