Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for analyzing changes in web analytics metrics. In one aspect, a method includes identifying a change in a web analytics metric for a website over a period of time, the web analytics metric being based at least in part on visitor data for the website over the period of time; computing a respective segment contribution score for each of a plurality of segments of the web analytics metric, wherein a segment contribution score for a particular segment is based at least in part on a comparison between a value of the web analytics metric and a value of the particular segment during the period of time; and identifying one or more of the plurality of segments as contributing to the change in the web analytics metric based on the respective segment contribution scores.

Abstract: Tracking data communications are received for single properties that include ambiguous event statistics. The event statistics are disambiguated by an analytics processing system by identifying account and visitor identifier pairs from account identifiers and visitor identifiers in the tracking data communications. For each account and visitor identifier pair, ambiguous event statistics are ordered by the corresponding event times and disambiguated.
