You may have noticed that you're seeing fewer posts from pages you've liked on Facebook. Once 12% of all of a page's "likes" would see a post. By 2012 it was down to 6% and Facebook plans to ratchet that number down to 1%. As a user, this is a good thing as you'll be seeing fewer "ad" type posts.
For small mom and pop type vintage businesses this isn't so great. Unless they pay to have their posts shared, their reach will continue to fade. According to Slate, Facebook realizes this and is currently cutting down more on the huge pages with 500,000 or more likes. But all posts will continue to lose their "reach" unless ads are placed [and paid for.]
How can you as a small vintage dealer or someone who wants to see a page's post get around this policy? Simply by "liking" posts and or commenting when you see them, you'll stay in the loop. Sharing is good too.
Sometimes the best solution to a problem is a simple one. Like, comment and share. It's as easy as that.
