A/B Testing is the process of comparing two versions of a webpage or app to see which one performs better. It involves showing the two variants (A and B) to similar visitors at the same time. The one that gives a better conversion rate, wins. In growth hacking, A/B testing is crucial for optimizing marketing strategies and product features.

A/B Testing Tips:

1. Always test one variable at a time for clear results.
2. Ensure a significant sample size to increase the reliability of the results.
3. Use the results to continually refine and improve your strategy.
