Abstract: Disclosed are various embodiments for determining the effects of modifying a network page based at least upon the implicit behaviors of users. An executable network page is generated to record the implicit behaviors of users. A position density map is then generated from the recorded implicit behavior to identify the content on the network page that has a high or low level of user interaction. The position density map is then analyzed to determine if the content on the network page needs to be revised. Subsequent A/B tests relating to revisions made to the network page may be run to ascertain the effect of changing the network page using the position density map.

Abstract: A service is disclosed for enabling web sites and other entities to provide item recommendations and other behavior-based content to end users. The service can be implemented as a web service that is remotely accessible over the Internet. Web sites use the web service's interface to report events descriptive of item-related actions performed by end users (e.g., item views, item purchases, searches for items, etc.). The web service analyzes the reported event data on an aggregated basis to detect various types of associations between particular items, and stores resulting datasets that map items to associated items. The web service's interface also provides various API calls for enabling the web sites to request item recommendations and other behavior-based content, including but not limited to personalized recommendations that are based on the event history of the target user. Advantageously, the web sites need not host the infrastructure for providing such content.
