For instance one of my most successful ads is a free-signup page with a rate of .12 PPC, I ran this ad until it gave me 150 clicks and I received a total of 10 post likes, multiple shares, but only 3 signups? And this is just CPA offers, when it comes to actually selling something I have had absolutely no luck, even if the ad would have converted as a post from a random to the same audience.
I have tweaked landing pages/audiences/ads/items/styles/etc many times yet something doesn't add up with my Facebook ad experience. Is there some big secret I'm missing to convert the Facebook audience? Any feedback is appreciated. Thank you
