If you’ve ever asked yourself questions like “Will a different button text increase sales?” or “Should reviews appear above the fold?”—you’re already thinking like an A/B tester.

This guide was written for e-commerce owners and marketers who want clarity without the jargon. Inside, you’ll find:

• What A/B testing actually is (with real, relatable examples)
• High-impact areas to test first—like CTAs, product pages, and ad landing pages
• Step-by-step setup using no-code tools like CustomFit.ai
• Common mistakes to avoid and how to know when a test is done
• How to personalize experiences beyond A/B testing for even better results

Plus, you’ll get a walk-through of the CustomFit.ai visual editor—your new secret weapon for editing, testing, and optimizing your store in minutes, not weeks.

This isn’t about flashy growth hacks. It’s about building a store that learns and improves every week—based on what your customers are actually doing.

If you're ready to stop guessing and start growing, this guide is for you.
