CRO
CRO (conversion rate optimization) is the practice of raising the share of store visitors who complete a purchase, through clearer pages, faster load times, better social proof, and checkout friction removal. Page builders, review apps, and analytics tools are all CRO levers; the discipline is measuring one change at a time instead of stacking guesses.
