The amount paid by the advertiser only when a user performs a specific action (purchase, lead, signup).
Unlike CPM (where you pay for impressions) or CPC (for a click), CPA is tied to the final conversion. The 'A' can represent a sale (Cost Per Acquisition) or a qualified lead (Cost Per Lead - CPL).
It is the tactical efficiency indicator for lower-funnel campaigns (MOFU/BOFU). It precisely controls the direct acquisition cost on a given channel.
"A very low CPA is not always a win if the volume is ridiculous or if lead quality is poor (leads that never convert into final customers). We steer the 'Qualified CPA' by interconnecting media buying data with your CRM (Hubspot, Salesforce)."
