Google's John Mueller says A/B tests with significant differences between variants may show visible effects in search results and indexing.
SERoundtable reports on guidance from Google's John Mueller clarifying how the search engine handles A/B testing. Mueller explained that when A/B test variants are "significantly different," that difference could be visible in search results, and depending on setup, one or the other version may be used for indexing. The guidance aligns with Google's official A/B testing best practices guide from 2022, which notes that small cosmetic changes typically have little impact on rankings, but larger variations may affect search visibility.
