How to use this tool

  1. Enter attributed conversions, eligible interactions.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Conversion rate = attributed conversions ÷ eligible interactions × 100. Match the interaction definition and reporting scope to the conversions you count.

A WORKED EXAMPLE

75 conversions from 2,500 eligible interactions give a 3% conversion rate. If one interaction can generate multiple conversions, the rate can exceed 100%.

What to keep in mind

Clicks, sessions and users are different denominators. Choose one consistently. This calculation does not estimate statistical significance or establish that a campaign change caused the result.

Common questions

Can conversion rate exceed 100%?

Yes, when multiple counted conversions can come from one interaction. If you count only one converting user per user, a result above 100% instead signals a counting mismatch.

Which denominator should I use?

Use the eligible clicks, sessions or users that match your question, and keep that definition consistent when comparing periods.
