Conversion rate optimization
From Conservapedia
Conversion Rate Optimization (CRO) is the data-driven process of improving the percentage of website visitors who take a desired action — whether that's completing a purchase, donation, subscribing to a newsletter, filling out a lead form, or any other key goal.
CRO focuses on understanding how users behave on your site, spotting friction points in the customer journey, and making targeted improvements to remove barriers and boost conversions. The goal? Get more value from your existing traffic without always needing to drive additional visitors.
