Track them as a system, not in isolation.
The Core Demand Metrics
CPM: Cost Per Thousand Impressions
Formula:
CPM = Ad Spend / Impressions × 1,000
CPM measures how efficiently you buy attention. It is most useful for brand and awareness campaigns where reach matters more than immediate action.
A rising CPM can signal increased competition, poor audience targeting, or low ad relevance.
CPC: Cost Per Click
Formula:
CPC = Ad Spend / Clicks
CPC measures how efficiently your ads drive traffic. It reflects both creative quality and audience intent. Lower CPC usually indicates strong alignment between message and audience.
CPL: Cost Per Lead
Formula:
CPL = Ad Spend / Leads
CPL shows how efficiently traffic becomes known prospects. It reflects landing page quality, offer strength, and form friction. High CPL often signals weak offers or poor conversion paths.
CPA: Cost Per Acquisition
Formula:
CPA = Ad Spend / Conversions
CPA measures the true cost to acquire a customer or desired outcome. It connects marketing activity to revenue and is one of the most important demand metrics for growth teams.
CTR: Click Through Rate
Formula:
CTR = Clicks / Impressions × 100
CTR measures message relevance. It tells you whether your creative resonates. High CTR with poor CPL or CPA often indicates curiosity without intent.
