It takes a lot of traffic to get statistically significant results for A/B tests. High-traffic websites like Google and Facebook should A/B test everything, but low-traffic websites shouldn’t bother.
At least that’s how the argument goes. But I would like to offer a different perspective. I think low-traffic websites should A/B test, not only because doing so has enormous cultural benefits, but also because A/B testing does work for low-traffic sites.
