A/B testing tools: AI search visibility ranking (2026)
How AI search engines rank a/b testing tools by visibility and citations. 20 brands measured monthly across Google AI Mode: which brands the AI names in answers, which domains it cites as sources, and how the leaders compare. Platforms used to run experiments on websites, apps, and funnels to compare variations, improve conversion rates, and personalize user experiences. Composite score: 70% visibility (% of AI answers naming the brand) + 30% citation rate (% citing the brand's domain). Full methodology →

When buyers ask AI engines like ChatGPT, Claude, or Perplexity to recommend A/B testing tools, Statsig comes up most often, appearing in 12.5% of all brand mentions across the category and earning citations in 75% of relevant AI responses. GrowthBook and Convert also rank consistently in the top three, making them the names you will see referenced repeatedly as you research this space.
The rankings reflect which domains AI engines trust as sources. The most cited are statsig.com, convert.com, growthbook.io, youtube.com, and reddit.com. The presence of Reddit and YouTube signals that AI engines are pulling from community discussions and video walkthroughs, not just vendor sites. Brands that appear frequently in those third-party conversations build credibility in AI outputs independently of their own marketing.
For a buyer using this page, the practical takeaway is to check whether a tool has strong third-party validation in places AI engines actually read, meaning recent Reddit threads, independent reviews, and tutorial content on YouTube. A brand ranking highly here is not just well-funded; it is the one practitioners are actively discussing and recommending outside of controlled brand channels, which is often a more reliable signal of real-world adoption.
At a glance
What we observed in this category
Statsig holds rank 1 with a composite score of 31.2, meaningfully ahead of GrowthBook at 23.8 and Convert at 22.5. The gap between first and fifth place (31.2 vs 17.5 for LaunchDarkly) is large enough to suggest a two-tier structure, where the top three brands capture disproportionate AI attention. Statsig's lead is reinforced by appearing in the top cited sources list alongside convert.com and growthbook.io, giving it both visibility and citation authority simultaneously.
Convert presents the clearest divergence between visibility and citation in the dataset. It holds 0.0% visibility but a 75.0% citation rate, matching Statsig's citation rate despite being invisible in AI-generated overviews. LaunchDarkly shows the opposite pattern, reaching 25.0% visibility with a 0.0% citation rate, meaning it is named in responses but never linked as a source. This split signals that being mentioned and being trusted as a reference are measured very differently by Google AI Mode.
Every brand in the top 10 records Google AI Mode as its top engine, confirming the audit reflects a single-engine dataset. The top cited sources extend beyond brand domains to include youtube.com and reddit.com, indicating Google AI Mode draws on community and video content when constructing A/B testing responses. Third-party domains posthog.com and personizely.net also appear in the cited sources list, suggesting AI responses reference product-adjacent tools or comparison content rather than relying solely on the brands being ranked.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
Rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 30 days and refresh this page automatically. How AI search ranking works →
