Conversion Rate

Conversion rate measures the percentage of Google Ads clicks that result in a defined conversion action - such as a purchase, signup, form submission, or phone call. It quantifies how effectively your ads and landing pages turn paid traffic into measurable business outcomes.

How to calculate conversion rate

Conversion Rate = (Conversions / Clicks) x 100

Why conversion rate matters for Google Ads users

Clicks without conversions are cost without value. Conversion rate is the metric that separates productive ad spend from wasted budget. A campaign with a high CTR but low conversion rate has a landing page, offer, or audience targeting problem that CTR alone will not reveal.

Positioning conversion rate in your metric tree between click metrics and revenue metrics reveals whether your paid funnel breaks at the engagement or conversion stage. Correlations with landing page and audience data pinpoint the specific cause of conversion issues.
