ROAS compares the revenue your ads generated with what they cost. A 4.19× ROAS means $4.19 back for every $1 spent. It ignores margin entirely — a healthy-looking ROAS can hide losing campaigns if your margins are thin.
CPM is the cost per 1,000 impressions. It measures how much you pay for visibility, regardless of whether anyone clicks or converts. Useful for comparing display, video and social placements on a common scale.
CPC (cost per click) tells you what each visit costs. CPA (cost per acquisition) tells you what each conversion costs. Together they reveal the efficiency of your funnel: a low CPC with a high CPA means traffic is cheap but not converting.
Conversion rate divides conversions by clicks (or visitors). It is the most important single number for landing page optimization — small changes in CR compound into large budget savings at scale.
