The past few months - and the past week in particular - have brought a number of changes to Facebook. Facebook users have been grumbling about 'Timeline'. As HubSpot points out, one effect of 'Timeline' is "The life of a status update is diminishing. Fast." So your content, posted for free, will be seen by fewer of your fans.
Next, Facebook is forcing business to convert to Timeline and thus eliminating landing tabs and like-gates, the mechanisms many dealers used to entice 'Likes'.
The effect of all this is to make your free use of Facebook much less productive. But much like how Google has diminished the effect of 'Free' SEO and placed more emphasis on PPC advertising, Facebook has introduced 6 new Ad Formats saying, in effect, "If you want your content seen and shared, pay us".
