I won't go into details, I've been testing with Facebook ads for the past 2 months, and results were absolutely unsatisfying. The last ad I've run (post boost ad) was catastrophic: I've specified I wanted people from certain countries, aged 19 to 29. And guess what I get?? Little boys aged 12!!!!
Organic reach has been much better for me than paid reach, and this just doesn't make sense to me. Why on Earth would I want to pay FB to spread my page posts much less than they spread for free??!!!
Either that there is a flaw in their algorithm, or it's designed to suck your blood with false promises!! And you cannot contest, Facebook will still charge you after you ran your campaign no matter the results... They estimate your post will reach 5000-10000 people, it only reaches 1000 with few engagements (although the algorithm supposedly "optimizes" your ad for engagement!!) and you end up paying for the promised 5000 reaches!!!
Look at the attached pic. How acceptable is this??!
