I have few questions about fb ads . My first campaign was very good, i invested 10$ and had 150 link clicks for that money and cost for 1000 impressions was 7$ i think. Now i started my second campaign and i wasted 20$ for 3-5 clicks . Cost for 1000 impressions is 36$+ . What is problem? Is it maybe because my audience have from 120k-300k reach or what? What affects the price of advertising & price of 1000 impressions? Thanks
