What is an A/B test?

Short answer

In an A/B test you show two versions to different visitors. Then you see which version works better.

Version A is what you have now. Version B has one change. For example a different headline or a different button colour.

Change only one thing at a time. Otherwise you will not know what caused the difference.

You need enough visitors for a fair result. Do you have few visitors? Then test big differences and wait longer.

Real-life example

A gardener tested two ad texts. "Garden ready in a week" easily beat "Professional garden landscaping". He now uses that text everywhere.
