Abstract: A system determines an extent to which advertisements are presented or updated within a document, a quality of an advertiser associated with an advertisement provided within the document, whether an advertisement in the document relates to an advertising document that has more than a threshold amount of traffic, and/or an extent to which an advertisement provided within the document generates user traffic to an advertising document related to the advertisement. The system generates a score for the document based, at least in part, on the extent to which advertisements are presented or updated, the quality of the advertiser associated with the advertisement, whether the advertisement relates to an advertising document that has more than the threshold amount of traffic, and/or the extent to which the advertisement generates user traffic to the advertising document. The system ranks the document with regard to at least one other document based on the score.

Abstract: A method may include receiving a document and an initial score for the document; determining that there has been a decrease in a rate or quantity of new links that point to the document over time; classifying the document as stale in response to the determining; decreasing the initial score for the document, resulting in an updated score; and ranking the document with regard to at least one other document based, at least in part, on the score.

Abstract: Ads are scored using, at least, user information and information associated with a user request, such as a search query or a document request. The scores may be used in determining whether to serve ads, how to serve ads, to order ads, to filter ads, etc. Items of user information, request-associated information, and/or ad information can be weighted based on previous uses of such information in the serving of ads and the performance of those served ads.

Abstract: Multiple packets are received that were transmitted by multiple mobile electronic device sensors located in a predefined area. The packets each include data detected by the sensors of multiple mobile electronic devices. At least a portion of the collected data is stored including multiple unique device identifiers that belong to multiple mobile electronic devices. Responsive to determining that at least two of the unique device identifiers are sequential, a set of values based on the at least two unique devices identifiers are associated as belonging to a same one of the mobile electronic devices.
