Various embodiments provide a frequent sites module which is designed to generate frequent sites for a user that include websites that are relevant to the user based on browsing patterns of the user. In one or more embodiments, the frequent sites are generated from user-engagement data that indicates engagement by the user with websites identified in the user's browsing history. A web platform, e.g., a web browser, can display the frequent sites for the user in a frequent sites user interface container to enable the user to efficiently navigate to the websites that are relevant to the user by selection of websites from the frequent sites user interface container. Various embodiments describe other aspects of frequent sites based on browsing patterns, including multiple-device frequent sites, device-specific frequent sites, domain-specific frequent sites, URL-specific frequent sites, decaying of frequent sites, recent frequent sites, and contextual frequent sites.
