The unit of measure Nelio A/B Testing uses in its plans is called “Tested Page Views.” Whenever a user accesses a page in your site that’s involved in a test, a Tested Page View is accounted. Usually, the number of Tested Page Views is far below your total number of site visits (e.g. if your site has 10,000 visitors per month and only 10% of them visit a page you are testing, your Tested Page View count would be only 1,000).
