The leak most businesses ignore
Most businesses obsess over getting more traffic. Far fewer ask a more valuable question: of the visitors I already have, why don't more of them become customers? That question is what conversion rate optimization (CRO) is built to answer.
Here's why it's so powerful. If 100 people visit and 2 call, you have a 2% conversion rate. Doubling your traffic to 200 visitors gets you 4 calls — but so does doubling your conversion rate to 4% with the same 100 visitors. The difference is that improving conversion costs nothing extra per visit, while buying more traffic costs money every single time. CRO is the closest thing to free growth a website has.
