Have you noticed the changes in Facebook over the past couple years? Perhaps a drop in your organic reach? An emphasis being placed by the platform on paid promotion? Perhaps you've seen a slowdown in your Page Likes? You're not alone. A lot of marketers are seeing these changes, and not all of them are positive.
