Glossary » conversion rate
the percentage of people who achieve a given task from a given starting point. On websites, the percentage of people starting at page A who get to page B. So for instance, if 1000 come to a homepage on a given day, and 600 of them click a link to a subpage, then you would say the site “has a 60% conversion rate of staying on the site after the homepage”. Similarly, if 1000 people come to the homepage and 100 of those people bought a product, you’d say that “10% of site visitors were converted to buyers”.
Conversion rate is a common web metric to evaluate the performance of a site.
