What it measures
Google Ads conversion rate is the percentage of ad clicks that result in a desired action, calculated by dividing conversions by clicks.
Formula
Conversion rate = Conversions ÷ Clicks × 100 · Cost per conversion = Spend ÷ Conversions
Worked example
45 conversions from 1,000 clicks is a 4.5% conversion rate, and $2,500 of spend works out to $55.56 per conversion.

Frequently asked questions
What is a good Google Ads conversion rate? +
Roughly 3–4% is average on Search; top performers exceed 10%. Display rates are typically much lower.

Any action you define as valuable — a purchase, form submission, phone call, sign-up, or download — that you've set up as a conversion in your account.
Why is my conversion rate suddenly lower? +
Common causes include broader match types, new low-intent keywords, landing-page or checkout issues, tracking breakage, or seasonal demand shifts.
