Why we picked it
This is the honest answer most founders don't want to hear: with a few hundred visitors a month, an A/B test almost never reaches statistical significance, so the winner it declares is usually noise. CXL walks through why that happens and, more usefully, what to do instead, from qualitative user testing to focusing on bigger swings that don't need thousands of conversions to prove out. It reframes the whole question from 'which button color won' to 'what is actually confusing people'.
A/B testing needs a large sample to be trustworthy; at low traffic you can wait months or years for a real result, and calling it early just measures randomness.
When you can't get statistical significance, switch to qualitative methods (user tests, surveys, session recordings) that tell you the why, not just the what.
Test big, obvious changes over tiny tweaks: a bold rework can show a clear effect at low volume where a headline word swap never will.

Keep it open next to your interview script and check each question against the list before your next call.
Why we picked it
This walks through Jobs to Be Done interviewing, which is built entirely around reconstructing a real past decision rather than asking anyone to imagine a future one. It gives you a concrete timeline structure so ask about the past becomes a repeatable method, not just a rule to remember.
