What is Conversion Rate Optimization
Conversion rate optimization, or CRO, is the practice of increasing the percentage of visitors who take the action you want – filling out a form, booking a call, adding to cart, completing a purchase, or dialing your phone number.
It is not redesigning your website because it looks dated. It is identifying the specific points where visitors hesitate, get confused, or leave, and removing those obstacles one at a time based on evidence rather than opinion.
The distinction matters, because most website changes are made on instinct. CRO replaces instinct with data: what people actually do on your site, where they abandon, and what happens to your numbers when you change it.
