Google Ads Management Term

CPA (Cost Per Acquisition)

CPA measures how much you spend to acquire one conversion (purchase, lead, sign-up). It's calculated as total spend ÷ total conversions. Also called Cost Per Action or Cost Per Conversion. It's the primary efficiency metric for performance campaigns.

Example in Practice

"Our search campaign achieved a £45 CPA against a target of £60, so we increased budget to capture more volume at this profitable level."
