Truth is, there was a time when the amount of likes you had on your Facebook business page really did matter.
It was a time when you could reasonably expect to reach a decent amount of your “likers” and followers organically just by posting content to your page.
Then, Facebook grew up and got a job.
That job is making money for share holders.
Since Facebook went public in 2012, they have been throttling down the organic reach that business pages get on their content.
Their goal is simple: they want you to run paid ads.
