How do I set up an A/B testing program?

Setting up an A/B testing program requires establishing processes, tools, and culture. Start by choosing an A/B testing platform that fits your needs and integrates with your site. Define your testing process: how to propose tests, prioritize them, set up tracking, analyze results, and implement winners. Establish a testing calendar and ensure you have enough traffic for statistical significance. Create a culture where decisions are data-driven, not opinion-based. Train your team on testing best practices. Start with high-impact, low-risk tests to build confidence. Document learnings and share results across teams. Example: A company set up a monthly testing cycle, with a testing board to prioritize ideas, resulting in consistent 2-3% conversion improvements each quarter.
