If they react positively (such as interact with it or click it to a landing page), the score goes up; if they react negatively, by telling Facebook they don’t want to see the ad, the score goes down.

The higher your relevance score is, the less you’ll pay on ads; Facebook directly confirmed this. We ran the same ad twice, once with strong targeting (relevance score of 8) and once with poor targeting (relevance score of 2.9).

Your relevance score will likely continually change as more users interact with your ad.
