Conversion rate formulas
Conversion rate measures the percentage of people in a measured group who complete the action you define as a conversion.
Worked conversion rate examples
250 conversions from 10,000 visitors equals a 2.50% conversion rate.
10,000 visitors at a 2.50% conversion rate would generate about 250 conversions.
To generate 250 conversions at a 2.50% rate, you would need about 10,000 visitors.
If your current rate is 2.50% and your target is 3.00%, you are 50 conversions below target at 10,000 visitors.
What conversion rate can help you understand
Conversion rate shows how effectively traffic, leads, or clicks move to the next action in your funnel.
A known conversion rate can help estimate how many conversions a given traffic level may produce.
A target conversion count and expected rate can be used to estimate the visitors or leads required to reach the goal.
Conversion rate vs. CTR and ROAS
CTR measures how often impressions turn into clicks. Conversion rate measures how often visitors, leads, or clicks complete a desired action. ROAS compares advertising revenue with ad spend. Looking at all three can help separate attention, action, and financial performance.
