Conversion Rate Optimization is a system for increasing the percentage of visitors to a website that convert into customers, or more generally, take any desired action on a web page.
There are a number of ways to increase the percentage of conversions on a website:
- A/B Testing
- Landing page optimization
- Content optimization
- Usability analysis
Essentially CRO is looking at why visitors to your website are or are not taking the action that you want them to and determining how to increase the percentage.
