Common AB testing mistakes for site search?

These are the most common A/B testing mistakes I've come across when trying to improve my site search:

1. Testing the wrong page. Not all pages are created equal. Focus on testing pages that are high-traffic and important to your conversion funnel, such as your product pages, checkout page, and homepage.
2. Testing without a hypothesis. Before you launch any A/B test, you should have a clear hypothesis in mind. What are you trying to improve? Why do you think your change will make a difference?
3. Not considering mobile traffic. More and more people are shopping on their mobile devices, so make sure your A/B tests are optimized for mobile users.
4. Not running separate tests for new vs. returning visitors. New and returning visitors have different needs and motivations. Running separate tests for each group will help you get more accurate results.
5. Not running the test long enough. It's important to run your A/B test for long enough to get statistically significant results. This will vary depending on the amount of traffic your site receives.
6. Making too many changes at once. If you make too many changes at once, it will be difficult to know which change is responsible for any improvement (or decline) in performance.
7. Not analyzing the results carefully. Once your A/B test is complete, it's important to carefully analyze the results. This will help you understand what worked and what didn't.
