Definition: Facebook’s Relevance Score is a rating between 1-10 which estimates how resonant the ad is with your target audience. It is shown after your ad has received over 500 impressions.
How it’s used: The relevance score of an ad is an estimation of how well your ad is responding with your target audience. The higher the relevance score, the better the ad is perceived to be performing.
If the score is high, it is more likely than competing ads to be shown to the target audience. So, an ad of 10 would be considered more relevant than an ad ranked 1.
The relevance score is determined by the following factors:
– how well the ad is performing
– positive feedback (for example clicks, video views, app installs)
– negative feedback (a user clicking “Hide ad”)
