The Updated Design for Facebook pages
Admins accessing their Pages today will see a tour of the refreshed design. After completing the tour, admins can switch to the new design right away. Admins that want to update their Pages before switching to the new design can wait up to two weeks before making the switch. However, every Page will automatically switch to the updated design two weeks after the tour has been viewed.
Along with the refreshed design, we’re also giving businesses more control over the look and functionality of their Pages. Now, admins can adjust the placement of sections in the top navigation menu and left-column menu.
