Ad Relevance Score is generated by Facebook based on the past and expected future performance of each ad. From Facebook’s documentation:
“Relevance score is calculated based on the positive and negative feedback we expect an ad to receive from its target audience. The more positive interactions we expect an ad to receive, the higher the ad’s relevance score will be. (Positive indicators vary depending on the ad’s objective but may include video views, conversions, etc.) The more times we expect people to hide or report an ad, the lower its score will be.
Ads receive a relevance score between 1 and 10, with 10 being the highest. The score is updated as people interact and provide feedback on the ad.”

How Does FetchRev calculate Relevance Score?
Each FetchRev campaign with Facebook ads enabled will typically have many different ads running for the campaign. Within campaign results, FetchRev displays:
- Relevance score per campaign
- Relevance score per audience
- Relevance score per ad creative
Each of these relevance scores is calculated based on the weighted average of impression scores for each ad within the grouping, with the number of impressions per ad used as the weighting factor.
Why is the Relevance Score sometimes ‘N/A’?
An ad must receive at least 500 impressions before Facebook will assign it a relevance score. If none of the ads within a particular grouping (campaign, audience, or ad creative) received more than 500 impressions, then we are unable to calculate a relevance score.
