GLOSSARY

What is conversion rate optimization? (CRO)

DEFINITION

Conversion rate optimization (CRO) is the practice of increasing the share of website visitors who take a valuable action. It works through research, changes to the page, and honest testing of whether the change helped.

CRO makes existing traffic more valuable, so it complements SEO and paid ads. No one can guarantee a lift, and some tests find no difference.
