Frequently Asked Questions
What is A/B testing?
A/B testing (split testing) is a method of comparing two versions of a webpage, email, or other marketing asset to determine which performs better. You show version A to one group of users and version B to another, then measure which version achieves your goal more effectively. This data-driven approach removes guesswork from optimization decisions.

How long should an A/B test run?
A/B tests should typically run for at least 1-2 weeks to account for day-of-week variations, and continue until you reach statistical significance (usually 95% confidence level). Most tests need 1,000-10,000 conversions per variation to be reliable. Never stop a test early just because one version is winning - you need sufficient data to make confident decisions.

What should I A/B test first?
Start A/B testing with high-impact, high-traffic elements: 1) Headlines and value propositions, 2) Call-to-action buttons (text, color, placement), 3) Hero images or videos, 4) Pricing page layouts, 5) Form fields and length. Focus on pages with the most traffic and biggest potential revenue impact, like your homepage, pricing page, or checkout flow.

How many variables should I test at once?
Test one variable at a time (A/B test) unless you have very high traffic that supports multivariate testing. Testing multiple changes simultaneously makes it impossible to know which change caused the results. Once you find a winner, implement it and move on to testing the next element. This systematic approach builds compounding improvements over time.
