Transmitting content items using search history profiles

A non-transitory machine readable medium having stored thereon processor-executable instructions that when executed cause performance of operations, the operations comprising:

• controlling a graphical user interface of a first device to display a search interface;
• receiving a first query, via the search interface, from the first device;
• responsive to receiving the first query, controlling the graphical user interface to display a plurality of search results corresponding to a plurality of web pages associated with the first query;
• receiving a selection, from the first device, of a first search result, of the plurality of search results, corresponding to a first web page of the plurality of web pages;
• responsive to receiving the selection of the first search result from the first device, storing, in a referral query database, an indication that the first query received from the first device is linked with the first web page associated with the first search result selected by the first device;
• receiving a message indicative of a second device accessing the first web page;
• determining that the second device did not access the first web page via the search interface;
• responsive to determining that the second device did not access the first web page via the search interface, analyzing the referral query database to determine, based upon the indication that the first query is linked with the first web page stored in the referral query database responsive to receiving the selection of the first search result from the first device, that the first web page accessed by the second device without the search interface is linked with the first query received from the first device via the search interface;
• responsive to determining that the first web page accessed by the second device without the search interface is linked with the first query received from the first device via the search interface, storing an indication of the first query in a search history profile associated with the second device;
• receiving a request for content from the second device;
• responsive to receiving the request for content, selecting a content item from a content items database based upon the first query;
• transmitting the content item to the second device;
• receiving a second request,
• wherein the second request comprises a referrer web address,
• wherein the referrer web address comprises a query identifier and a set of characters associated with a second query;
• analyzing the second request to determine the second query,
• wherein the analyzing the second request to determine the second query comprises:
• comparing one or more parts of the referrer web address with a list of query identifiers to identify the query identifier based upon a determination that the query identifier is comprised within the list of query identifiers;
• and
• identifying the set of characters associated with the second query based upon a location of the set of characters, in the referrer web address, with respect to the query identifier;
• and
• storing, in the search history profile, an indication of the second query.

A computing device comprising:

• a processor;
• and
• memory comprising processor-executable instructions that when executed by the processor cause performance of operations, the operations comprising:
• receiving, by a content system, a first request from one or more servers hosting a web page,
• wherein the first request comprises a representation of a second request, from a first device to the one or more servers hosting the web page, to access the web page,
• wherein the first request comprises a referrer web address,
• wherein the referrer web address comprises a query identifier and a set of characters associated with a query;
• analyzing, by the content system, the first request, comprising the representation of the second request to access the web page, to determine the query that the one or more servers at least one of received from the first device or used to determine the web page,
• wherein the analyzing the first request to determine the query comprises:
• comparing one or more parts of the referrer web address with a list of query identifiers to identify the query identifier based upon a determination that the query identifier is comprised within the list of query identifiers;
• and
• identifying the set of characters associated with the query based upon a location of the set of characters, in the referrer web address, with respect to the query identifier;
• storing, by the content system and in a search history profile associated with the first device, a representation of the query that the one or more servers at least one of received from the first device or used to determine the web page;
• receiving, by the content system, a second request for content from a second device associated with the search history profile;
• responsive to receiving the second request for content, selecting, by the content system, a content item from a content items database based upon the query;
• and
• transmitting, by the content system, the content item to the second device.
