It depends on your market. Some demographics have CTRs hovering around 0.4%, while others are lucky to get above average (0.02%). If you have good competition, it’s going to be tough. In untapped markets, Facebook ads have a great CTR. Personally, we wouldn’t run an ad with a click-through-rate below 0.9%—we find that the ads are no longer profitable when CTRs fall below 0.9%.
