Those of you who woke up this morning and checked your Facebook insights for their Facebook page saw an interesting message that doesn’t bode well for like counts. The message informs Facebook page admins that on March 12th they may see a reduction in the number of likes they currently have on their page. "We’ve recently updated the way we measure how many people like your Page. Pages may see a decrease in likes after March 12, when we removed likes from inactive Facebook accounts." http://www.easysitenetwork.com/your-facebook-page-likes-are-about-to-drop/
oooooh boy, thanks for the update, this could be painful. I don't want to know how many are inactive lol
I think it is still effective in gaining loyal audience going to your website. It is still important to honor search engine rules.
