On March 30th, Facebook will forcibly migrate all Pages onto the Timeline redesign, but Facebook tells me it only took 10 days for 8 million of the more than 37 million Pages that have been set up to opt into the change. The stats are a sign of success that show the added features are ones admins want, considering tons of Facebook Pages get set up and forgotten about.
However, it will take a while to see whether Timeline actually helps Pages market more effectively. So far the most popular Pages that have switched haven’t seen growth rates increase. With more to look at, the Like button might be overshadowed.
