CPM is cost per thousand impressions, CPC is cost per click, CPA is cost per action. Click-through rate converts CPM to CPC, and conversion rate converts CPC to CPA, improve either rate and every downstream cost falls.
CPA, because it is the only one tied to money coming in. CPM and CPC are diagnostics that tell you whether a high CPA is a creative problem or a landing page problem.
Roughly 1–2% on Meta feed placements and 2–5% on search where intent is higher, with wide variation by industry. A CTR far above normal alongside poor conversions usually means the ad promises something the page does not deliver.
Auction pressure. Seasonal competition, a broadened audience or creative fatigue all raise CPM, and Q4 in particular reprices every market upward.
