Facebook is planning to introduce a content-sharing button that other websites can embed on their pages.
The new Facebook "like" button will work in a similar way to facilities from Twitter and Digg that enable users to share content with their social networks, according to the Financial Times.
The Facebook button, expected to be announced at Facebook's F8 annual conference that starts in San Francisco on 21 April, will allow users to signal the content they like on sites around the internet.
Facebook has denied that the new tools will allow the company to track users and serve targeted adverts.
Facebook currently targets ads based on what information users fill out in their profile, including location, age, gender and favourite activities and music bands.
Under changes to be announced this week, Facebook is expected to replace the "Become a fan" button with an invitation to say "I like" a brand.
