I am running a FB campaign which entails 8 ads 2 images, My overall campaign has about a .13 ctr, some of the ads are getting reach 10,000 plus, others are still at 2 and 8 , a couple at about 300 then they stopped getting any reach, I even put my max bid up to 3 dollars a click and nothing, and paused all the other ads to see if it was just sending traffic to certain ones. all 8 of the ads are targeted to certain age demographics, Does facebook put certain ads up to different ages at different times. Very confused on this., I did however get my CPC to 34-45 age group down to about 30 cents though which I know i can get it lower to I just want to target the younger and older audience as well. Any tips or info would be much appreciated. Thank You.
