# Conversion Rate Optimization (CRO)

Conversion rate optimization (CRO) is the practice of increasing the share of website visitors or users who take a desired action by studying their behavior and testing changes to pages and flows.

Also called: CRO

## Why it matters

CRO gets more results from traffic a company already has. If a landing page converts poorly, sending more ad traffic to it only raises the cost per lead. Improving the page, the form or the offer lowers that cost and makes every channel feeding the page more efficient.

CRO usually follows a cycle: study analytics, recordings and user feedback to find where people drop off, form a hypothesis, test a change against the original, and keep the winner. Tests need enough traffic to give a reliable answer, so low-traffic B2B sites often focus on bigger changes, such as the offer or the form, rather than small design tweaks.

## Example

A company notices that most visitors to its demo page leave at a form with eleven fields. It tests a version with four fields and moves the remaining questions to the booking confirmation step. The shorter form produces more completed requests, and the sales team still gets the details it needs before the call.
