# Conversion rate optimization (CRO)

> Raising the share of visitors who do the thing — buy, book, enquire — by fixing friction, not by buying more traffic.

Traffic is bought; conversion is earned on the page. Doubling a 2% conversion rate is the same revenue lift as doubling traffic, at a fraction of the cost — and the work is usually subtraction: a shorter form, a clearer price, a button that says what happens next, a page that loads before the doubt does.

The method is diagnosis before surgery: watch where people leave (checkout analytics, session recordings), form one hypothesis, change one thing, measure. The failure mode is optimizing the wrong layer — A/B-testing button colors on a page whose price scares people away is rearranging chairs.
