How do you calculate conversion rate?

Conversion rate = conversions ÷ visitors × 100. For example, 50 conversions from 1,000 visitors is a 5% conversion rate. Conversion rate is the share of visitors who completed a desired action. Track it over time and by source to spot what is working.

Understanding your result

Formula and method

Assumptions and limitations

Count visitors and conversions consistently (sessions vs unique users). A rate alone lacks context — track it over time and by source.

Frequently asked questions

Conversions or revenue?

This measures action count. For revenue per visitor, combine it with average order value.

Why track conversion rate by traffic source?

Different sources bring visitors with different intent, so a blended rate can hide what is working. Splitting the rate by channel, campaign or page reveals which sources send visitors who actually complete the action, helping you focus effort where conversion is strongest rather than guessing.

How should I define a conversion?

A conversion is any action you count as success, such as a purchase, sign-up, download or enquiry. Decide on one clear definition before measuring, and keep it consistent, so that comparisons over time and between sources reflect real changes rather than a shifting definition.
