When exploring A/B testing tools, AI engines frequently highlight Statsig as a leader in the field with a notable visibility percentage of 25.0. Other prominent brands like VWO and GrowthBook also consistently appear in these discussions. This suggests a strong presence and recognition of Statsig within the marketing industry, making it a top consideration for buyers.
The rankings reflect data sourced predominantly from popular aggregator and review sites like cpoclub.com and mida.so, as well as user-driven platforms such as reddit.com. This heavy reliance on varied sources indicates a combination of expert and user opinions shaping consensus within AI engine suggestions.
For buyers, understanding these rankings implies considering which brands have solid endorsements from both industry experts and active users. One key aspect to focus on is third-party validation, as AI engines prioritize brands with recent reviews and established authority, especially those excelling in their specific subcategory.
At a glance
What we observed in this category
Statsig leads the A/B testing tools category with a composite score of 28.8, ahead of VWO at 25.0 and a cluster of brands sitting at 20.0 or below. The gap matters because the category average visibility is just 7.5%, meaning Statsig's 25.0% visibility represents more than three times the norm. VWO matches Statsig on raw visibility but trails on citation rate (25.0% vs 37.5%), which is what separates their composite scores and signals that Statsig content is being used as a source, not just mentioned.
The most striking divergence between visibility and citation sits with Optimizely and GrowthBook. Optimizely achieves 25.0% visibility, equal to the category leaders, yet holds a 0.0% citation rate, meaning AI surfaces it by name but does not anchor claims to its content. GrowthBook shows the inverse pattern: 12.5% visibility but 37.5% citation, matching Convert exactly. This pattern suggests that brand recognition in AI responses does not automatically translate into being treated as a trusted source for factual grounding.
Google AI Mode is the top engine for every brand in the dataset, confirming this category's AI visibility landscape is effectively a single-engine contest at present. The cited sources list includes cpoclub.com, mida.so, reddit.com, and optibase.io alongside brand-owned domains like statsig.com, growthbook.io, and convert.com. The presence of reddit.com and third-party review or tutorial sites signals that AI is drawing on community and aggregator content, not just vendor documentation, when constructing answers about A/B testing tools.

How to read this AEO 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 →
AEO 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 90 days and refresh this page automatically. How AI search ranking works →
