# AdPerformance

> One ad's funnel — campaign, ad set and ad.

Ad identity rides on UTM columns by convention (utm_campaign, utm_term,
utm_content), so a call whose link omitted them is absent entirely rather than
bucketed as unknown. When `ad` and `adSet` are null across every row, these are
campaigns rather than ads.
