Facebook will roll out Timeline for pages on March 30th, which will incorporate a cover photo, profile picture, custom views and apps, and friend activity similar to user profiles. The cover photo can be up to 851x315 pixels and cannot include certain promotional content. The profile photo dimensions are 180x180 pixels. Page admins will be able to customize tabs and views, see insights and messages from fans in real-time, and pin important posts to the top of the timeline. The timeline changes are aimed at providing more opportunities for pages to engage fans and promote content through ads and posts.
