Facebook Ads has tool called conversion tracking that helps you making sense of the ads you are running on the site:
Conversion tracking helps businesses measure the return on investment of their Facebook Ads by reporting on the actions people take after viewing those ads. Advertisers can create pixels that track conversions, add them to the pages of their website where the conversions will happen, and then track these conversions back to ads they are running on Facebook. Conversion tracking also helps businesses leverage optimized cost per impressions (oCPM) to show ads to people who are more likely to convert off Facebook.
