When buyers inquire about Enterprise search AI, AI engines frequently highlight Glean as the leader in this category. Glean, along with other top brands like Elastic and Sinequa, frequently appear in answers due to their visibility, Glean, for instance, holds an impressive visibility of 50.0%. This prevalence reflects their strong presence in the market.
The rankings are influenced by the domains AI engines use as sources, which include major aggregator and review sites like google.com, gartner.com, and gosearch.ai. These sources offer broad industry insights and expert reviews, elevating brands that maintain prominent visibility across these platforms. It's this diverse pool of information that drives consistent citation in AI responses.
For buyers evaluating options, consider how AI engines prioritize brands with recent expert validations and solid reputations on widely-recognized sites. A brand's ability to maintain topical authority and engage with current industry-specific discourse could greatly enhance its visibility, making recent reviews and third-party endorsements critical factors in the decision-making process.
At a glance
What we observed in this category
Glean dominates this category with a visibility score of 50.0%, which is more than eleven times the category average of 4.4%. No other brand comes close, with Elastic, Sinequa, and Perplexity each sitting at 12.5% visibility. That gap is significant for AEO purposes because Google AI Mode is already consolidating answers around a single brand, leaving the remaining 19 brands competing for a narrow share of AI-generated responses. The composite score spread (42.5 for Glean versus 12.5 for Elastic) reinforces how lopsided this category currently is.
Coveo presents the sharpest divergence between visibility and citation in the dataset. It holds zero visibility yet carries a 12.5% citation rate, meaning Google AI Mode references Coveo as a source without surfacing it as a named recommendation. Sinequa and Perplexity show the opposite pattern, each appearing at 12.5% visibility with zero citations. This split reveals that being named in an AI answer and being trusted as a source are two distinct AEO outcomes, and in this category several brands achieve only one of them.
Google AI Mode is the top engine for every brand in this dataset, confirming that the audit reflects a single-engine picture. Among the top cited sources, third-party domains including gartner.com, gosearch.ai, instaclustr.com, and premai.io appear alongside glean.com itself, suggesting the AI is anchoring on analyst and aggregator content rather than vendor-owned pages for most citations. The presence of glean.com in the cited sources list is notable, as it is the only brand domain to appear there directly, reinforcing Glean's structural advantage in this category.

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 →
