Even as it struggles to find alternatives to being acquired by Microsoft, Yahoo continues to push elements of a turnaround plan devised by Jerry Yang, the company's co-founder and chief executive.
On Tuesday, Yahoo plans to introduce a service called Buzz that relies on users to help it compile the most popular articles from around the Web. Yahoo plans to include some of those on its front page, hoping to attract more users and turn it into a hub for driving traffic to other publishers.
Yahoo will also announce Tuesday that it will allow fuller previews of online publishers' sites in search results. A search result displaying a user of the social network LinkedIn, for instance, could include links to that person's connections and full profile, and a result displaying a restaurant may include direct links to a reservations page or reviews.
Both moves are part of a strategy Mr. Yang has been promoting to open Yahoo's services to third-party publishers.
