How To Calculate Your Website Or Campaign Conversion Rate

Calculate website conversion rate by Invesp

How To Calculate Conversion Rate

The basic conversion rate formula is:

Conversion Rate = Total number of conversions / Total number of sessions

In a month, if your site reaches a total of 100,000 sessions and registers a total of 10,000 orders, your conversion rate is = 10,000/100,000 = 10%

What is the number of visitors used in this formula?

When you look at your analytics program, the number that is used in the formula is the number of sessions. If a single visitor might come to the website twice, then we use these two sessions in our calculations.
