At some point they decided to basically stop showing updates to your own followers. Affected pages reported a drop of 90%+ in feed views, and the only way to reach your audience again was to boost your own posts, which is a paid service.
The reason for this is we don’t just post 24-7 about how amazing we are.
We post 1-2x a week, and our followers genuinely like us and are fans of the business.
So… the changes on FB haven’t impacted all businesses in such a negative way.
