A/B Testing: Let Data Decide

Stop Guessing, Start Testing

You: 'I think the signup button should be red.'

Your friend: 'No, blue converts better.'

A/B testing: Let's show red to 50% of visitors, blue to the other 50%, and see which actually performs better.

Result: Blue gets 23% more signups. Data wins. Opinions lose.

This is A/B testing: comparing two versions to see which one works better in the real world.
