An Internet infrastructure that supports searching of web links selects search results by processing browser activity information along with one or more of favorite lists, and related metadata, user profiles, and trends based on browser activity behavior and favorite behavior. The Internet infrastructure consists of a plurality of web browsers located on client devices. The web browsers are incorporated with a browser activity-monitoring module that tracks user's Internet usage, processes this information, and sends this information periodically or upon user request to the server to aid in improving search operation results. The search engine server is communicatively coupled to the plurality of web browsers and supports delivery of search results/web links to the client device based upon a search string, browser activity information, and possibly the favorite lists and related metadata. The search engine server stores the gathered browser activity information, favorite lists, and related metadata in one or more server database that is associated with the search engine server, and delivers search results.
