Why Facebook reduced the coverage of advertising?

[morris]

Hello,

Maybe someone had this situation. From the very beginning of the advertising campaign on Facebook, the budget was set at $20 per day, the coverage was 2000 people stable every day. After changing the budget by $25, changes in the Interests and exclusion of several cities, the coverage collapsed and for 2 days the coverage rate is ridiculous - 60 people a day. 

Who knows why the indicators have changed so much? Could the change of the foregoing affect the coverage? How to solve this?

Every Page on Facebook wants everything they post shown to everyone. But people only read a limited amount of News Feed per day. There simply isn’t room for everything, and the competition for feed space is intensifying

because they need more money

while advertising, check your coverage first. And check the range of age, then check distance. And try to promote again your page. I think it will be ok.

Because it's their policy to make people see more posts from their friends and relatives than pages' posts. I don't know why they do it.
