At a glance
What we observed in this category
EY leads the accounting firms AEO landscape with a visibility score of 75%, more than double the 37.5% held by PwC, Deloitte, and KPMG. That gap is significant because it means Google AI Mode surfaces EY in response to three times as many relevant queries as BDO, RSM, or Grant Thornton, each sitting at just 12.5%. With a composite score of 52.5 against a category average visibility of 11.9%, EY occupies a structurally different tier from every other brand in the dataset.
The most striking pattern across all 20 brands is a citation rate of exactly 0.0% for every firm, including EY. This means Google AI Mode is mentioning these brands by name with reasonable frequency but is not linking out to their owned domains as source material. Visibility and citation are completely decoupled in this category, which tells analysts that brand mention volume does not translate into trusted source status inside AI-generated answers at present.
The sources Google AI Mode does cite in this category are almost entirely third-party properties: vault.com, big4accountingfirms.com, gmac.com, and miamiherald.com appear alongside google.com and youtube.com. None of the Big Four or mid-market firm domains appear in the cited sources list. This anchoring on external directory and media properties, rather than firm websites, defines the current AEO structure for this category and explains the zero citation scores across the board.

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 →
