How each metric in your reporting is calculated:
Impressions: the number of times your content or ad was displayed, counting every appearance on screen
Reach: the number of unique people who saw your content or ad
Engagements: every interaction with the content: likes, comments, shares, and clicks
Engagement rate: engagements divided by reach, showing how actively the audience responds
Clicks: the number of times people clicked through to your destination
Conversions: desired actions completed after interacting with the content, such as a purchase, signup, or form fill
Sales and revenue: the number of attributed sales and their total monetary value
ROAS: revenue divided by ad spend
CPA: ad spend divided by conversions
EMV (Earned Media Value): the estimated value of the organic exposure, calculated as what the same exposure would have cost as paid advertising
Paid metrics come from your connected ad account; organic metrics come from the creator's connected social pages, as first party data.
