What Is A/B Testing?
A/B Testing (also called split testing) is a way to compare two versions of something, like a landing page, form, button, or headline, to see which version leads to more conversions.
Version A is your original (the “control”)
Version B is the variation you’re testing
Visitors are randomly shown one version or the other, and performance is measured based on a specific goal, like form submissions or purchases. If version B does better, you have the data to back up the change.
Why A/B Testing Matters
Rather than guessing what will improve your site, A/B testing gives you real evidence. It helps you:
- Make informed design and content decisions
- Improve conversion rates over time
- Avoid costly redesign mistakes
- Optimize email subject lines, CTAs, images, and more
How Conversion Bridge Supports A/B Testing
While Conversion Bridge doesn’t run A/B tests, it helps support them by:
- Tracking form submissions, clicks, purchases, and engagement metrics from 76 WordPress plugins
- Sending those events to 19 analytics tools and 11 ad platforms
- Tracking conversion events the same way no matter which version a visitor sees
That gives you the same conversion data for version A and version B to compare.
Frequently Asked Questions
How long should I run an A/B test?
It depends on your traffic volume, but ideally you run the test until you reach statistical significance, usually a few hundred conversions per variant.
Can I A/B test with low traffic?
Yes, but stick to testing big changes (like layout or messaging) instead of small tweaks. It may take longer to get reliable results.
Should I only test one thing at a time?
Yes, if you change multiple variables at once, you won't know what made the difference.
