Abstract: Conditionally combining data from several sources may include retrieving data from several sources in response to a single request and using one or more redirection responses. The request from a client device may include a device identifier, a third-party identifier, a join identifier based, at least in part, on the device identifier, and first data from a first source, such as a first cookie, associated with the received request. A redirection destination may be determined based on configuration data associated with the third-party identifier, such as whether one or more services are selected and/or activated by a publisher of a resource. A redirection response is transmitted to the client device responsive to the received request and includes the redirection destination and the join identifier. The first data from the received request and second data received from the redirection destination may be associated based on the join identifier.

Abstract: The subject technology provides configurations for propagating information from an initial analytics tracking data communication to subsequent analytics tracking data communications at an analytics server. In one example, the subject technology receives an analytics tracking data communication. The subject technology determines if the received analytics tracking data communication includes state changing information based on analytics tracking data included in the analytics tracking data communication. The subject technology then determines one or more attributes for propagating to subsequent analytics tracking data if the analytics tracking data communication includes state changing information. The state changing information are stored as one or more of the determined one or more attributes. The subject technology stores the analytics tracking data including the determined one or more attributes.

Abstract: A method for loading a web page is provided. Primary executable script are asynchronously loaded. Commands associated with the primary executable script are pushed onto a first queue and processed by asynchronously loading secondary executable script if the command is a dependency command and pushing the dependency command onto a second queue; registering secondary executable script referenced in the command if the command is a fulfillment command, and pushing the command onto the second queue if the command is neither a dependency nor a fulfillment command. Commands in the second queue are processed by, if the command is a dependency command, determining if the secondary executable script referenced in the dependency command is registered, and associating the secondary executable script with an object if the secondary executable script is registered. If the command is not a dependency command, then the command is executed and removed from the second queue.

Abstract: A method for sessionization of visitor activity includes receiving a first activity of a first client and a first client identifier from the first activity of the first client; the first client identifier stored at the first client; creating a first session from the first activity and the first client identifier; receiving a session link associated with the first activity; and creating a visitor-identified session based on the first client identifier, the first activity, and the session link.

Abstract: A system and method for storing a cookie of a web page are provided. An initial cookie value corresponding to a web page is received, and a domain depth of a uniform resource locator (URL) of the web page is identified. Cookie data including a name-value pair is generated for the web page. The name-value pair includes the initial cookie value and the identified domain depth. The generated cookie data is stored corresponding to a domain of the web page.

Abstract: The subject technology provides configurations for determining resource configuration information for applying to analytics tracking data. Resource information is determined based on analytics tracking data from an analytics tracking data communication in which the resource information includes a corresponding resource associated with a source, and the analytics tracking data includes data for tracking an activity associated with the source. The subject technology determines resource configuration information based on the determined resource information in which the resource configuration information includes one or more attributes associated with the corresponding resource. One or more attributes are then applied from the determined resource configuration information to the analytics tracking data.

Abstract: The subject technology provides configurations for processing late and/or out-of-order analytics tracking data communications. An analytics tracking data communication is received. The subject technology determines a timestamp included in the analytics tracking data from the received analytics tracking data communication. The subject technology determines a session based on the determined new state changing information. The subject technology determines other analytics tracking data included in the analytics tracking data communication to associate with the determined new state changing information in the determined session if new state changing information is included in the analytics tracking data from the received analytics tracking data communication. The analytics tracking data and the other analytics tracking data associated with the new campaign information is then stored.

Abstract: The subject technology provides a session associated with web site or application traffic data. An analytics tracking data communication is received. The subject technology determines analytics tracking data from the received analytics tracking data communication in which the analytics tracking data includes data for tracking an activity associated with a web site or application and includes visitor information. A new session associated with the analytics tracking data is created if it is determined that the activity is associated with an initial visit of a unique visitor corresponding to the visitor information. The subject technology determines campaign information for populating the new session associated with the analytics tracking data. The analytics tracking data including the determined campaign information is then stored.
