What it is
A/B testing is the practice of running two versions of something — an email subject line, a landing page headline, a call-to-action button, an ad image — and showing each version to a portion of your audience to see which performs better. One change at a time, measured against a control. The version that wins becomes your new baseline, and you test the next thing. Over time, you compound small improvements into dramatically better results.
Why it matters
A/B testing replaces opinions with data. Instead of debating whether the button should say "Get Started" or "Book a Call," you find out. The businesses that test consistently — even casually — make smarter decisions and waste far less money on things that don't work.
The mistake most people make
Testing too many variables at once or calling a winner too early. If you change the headline, the button, and the image at the same time and performance improves, you have no idea which change caused it. Test one thing. Wait for statistical significance. Then test the next thing.
