how much i have to spend to have a good result with facebook sponsoring ???!!!

I want to know how much I should spend money in instagram and facebook  to have a  very good result and a great number of download for my games??

Id be curious on advertising budgets as well..
Rule number 1..  the game has to be fun.. has to be good.. or advertising and whatnot wouldnt really help

Yeah, sure.  So any idea about this  ?

Paying for advertising is only viable if the average income from each download is more than the money needed to pay for one download (via advertising) if that makes sense. So it really depends on what your game is.

And what do you think about  the idea of publishing my game with a publisher like voodoo ketchapp .. ect ? It's a good idea ?  Could I trust them?
