A popular Facebook page is considered one of the best ways to reach customers in the social media era as it delivers information directly to the news feed on products users have expressed interested in.

That means companies advertising their page on Facebook in an attempt to win those all-important 'Likes', may not be getting the right amount of bang for their buck.
Facebook downplays the problem
The BBC's Rory Cellan-Jones put the theory to the test by setting up his advert for a bagel company targetted at the US and UK. Within days there were 3,000 likes from all over Asia.
Facebook makes its money from these advertisers, so naturally has denied that this is a significant problem. The higher the Like count, the more it gets paid.
The social network estimates that around 50 million of its 900m+ profiles may be fake.
