A/B testing is a method for comparing two versions of something to see which performs better.
- A = the original or control version
- B = the new or changed version
How it works
- Split your audience randomly into two groups.
- Show group A version A and group B version B.
- Measure a result, like:
- click-through rate
- sign-ups
- purchases
- time spent
- Compare the results to see which version wins.
Example
If you want to test a homepage button:
- A: “Buy now”
- B: “Get started”
If version B gets more clicks, it may be the better option.
Why use it
- Reduces guesswork
- Helps make data-driven decisions
- Useful for websites, apps, ads, emails, and product features
Important note
A/B testing should use:
- random assignment
- enough sample size
- one change at a time when possible
