Conversion rate optimization is the deliberate, ongoing practice of testing and refining a page’s elements, like headlines, form length, or button copy, specifically to increase the percentage of visitors who convert, treating the existing conversion rate as a number that can be systematically improved rather than accepted as fixed. It typically relies on structured A/B testing rather than gut instinct, since even confident guesses about what will improve a page frequently turn out wrong once tested against real visitor behavior. Because it improves results from traffic a business already has, CRO is often one of the highest-return activities available, especially compared to the cost of acquiring entirely new visitors.
An e-commerce team practicing conversion rate optimization might A/B test two versions of a checkout page, simply moving the shipping cost disclosure earlier to see if it reduces cart abandonment.
A software company could run this same kind of testing on its pricing page, checking whether removing an extra plan tier makes visitors more likely to actually sign up.
Agencies specializing in this discipline often start with heatmaps and session recordings, using real user behavior data to decide exactly what to test next instead of guessing.
