Facebook isn’t the newspaper where “if you post it, they will see it.” This takes a little bit of shift in how we view concepts such as “spam” and “bugging” but algorithms don’t work like our chronological brains.
What to do if you’re a small business, church or non-profit with a small number of Facebook Page likes but looking to grow? Post video. Post often. Don’t assume that because you post something on your Facebook Page (not your personal one) that all of your followers or audience will see it.
What’s more likely is actually another News Feed update introduced in June 2016, which put increased emphasis on content posted by friends and family over Page posts. Facebook’s always looking to get people sharing more personal updates, and those updates generate more engagement, which keeps people on platform longer, while also providing Facebook with more data to fuel their ad targeting.
