A definition

Conversion rate optimisation (CRO) is the practice of increasing the share of visitors who take a desired action by understanding what stops them and removing those obstacles.

It is not copying a competitor's page, changing button colours at random, or adding pressure tactics. Those can produce short-term blips while damaging trust.
