1. A/B testing is synonymous with modern web development. In a simple A/B test, two different versions of a page, an “A” version and a “B” version, are sent to two similar sets of random viewers. This is also known as A/B/n or Split testing.

2. The A and B versions may be totally different, or may differ only in key areas; for example, the headline, image or call to action.

3. The goal of an A/B test is to determine which version performs best. Metrics that may be evaluated include email opt-ins, link clicks, bounce rate, or purchases.

4. With A/B test you can:

• USP lists
• Headlines
• Layout
• Colours
• Buttons
• Calls to action
• Contact details
• Shipping details
