On Thursday, September 25, Yahoo.com began implementing what it has called the Content Optimization Knowledge Engine. The engine draws on personalization technology to provide the user with a combination of articles and Web sites that have been specifically screened and interpreted from the user’s previous activity. The move is considered an overhaul of the Yahoo Site, which currently is the highest visited Web site on the Internet at 82 million visits per day. In essence, the new Yahoo portal is a combination of editorially picked and self-selected articles or Web pages. Such a strategy provides the user with links of sites she most-commonly visited, in addition to related links that she may not yet know about, but will likely be interested in. This information is in a sidebar located on the left side of the Yahoo home page. The user can also create customizable pages by creating a new tab and dragging and dropping applications. The tab can be named, which is good for organizing themed pages.

Currently, the portal allows users to also sign onto Google and AOL accounts from the My Yahoo homepage. The ability to add other third party applications such as Facebook, Myspace, and Twitter is part of Yahoo's plan of development.

Post-implementation, Yahoo expects the home page to be a “starting point” for other areas of the Web. Whether the overhaul will be a testament to efficiency or encumbrance is yet to be determined. Researchers expect the implementation to take more than 6 months, as has been the case with past Yahoo renovations.
