You’re not only trying to seduce the target here: Facebook algorithms are also judging your performance. The more attention you draw, the higher your relevance score (and the less you’ll need to pay to get in front of new eyeballs). The relevance score is a rating of 1 to 10 based on how your audience is responding to your ad. If you’re below 5, just drop it. 6 and 7 are acceptable. But you should really aim for 8+. With the right audience and a great creative, even a 10 is totally within your reach.
