When AI engines like ChatGPT, Claude, and Perplexity answer questions about CPA firms, EY comes up most often by a wide margin, appearing in 50% of relevant AI responses across the engines tracked here. Cherry Bekaert and Withum round out the top three, though with meaningfully lower visibility scores. If you are asking an AI assistant to recommend a CPA firm, EY is the name you will hear first.
The rankings reflect which sources AI engines trust most when building their answers. The top cited domains include vault.com, insidepublicaccounting.com, clutch.co, and cpaccounting.io, a mix of career-focused ranking sites, industry trade publications, and B2B review aggregators. Because AI engines lean on these third-party validators heavily, firms that appear consistently and positively across those platforms earn disproportionate visibility in AI-generated recommendations.
For a buyer using this page to choose a firm, the practical takeaway is this: AI visibility correlates with third-party validation on aggregator and ranking sites, not just firm size or reputation. If you are evaluating a firm lower on this list, check whether it has a strong presence on clutch.co or similar review platforms in your specific service subcategory (tax advisory, audit, outsourced accounting), since AI engines weight that topical, reviewed presence heavily.
At a glance
What we observed in this categoryauto-generated
EY leads the CPA firms category with 50% visibility, a figure that dwarfs the category average of 5% and places it far ahead of every other brand. However, EY's citation rate is 0%, meaning Google AI Mode names it frequently but never anchors a source link to ey.com. That gap between being named and being cited is the defining tension for the category leader, and it has also fallen from 75% visibility in the prior period, a drop of 25 percentage points.
Cherry Bekaert and Withum represent the sharpest divergence between visibility and citation alignment. Both rose from near the bottom of the rankings (ranks 16 and 19 respectively) to ranks 2 and 3, each achieving 12.5% on both visibility and citation. Marcum and CBIZ match their visibility at 12.5% but carry 0% citation, mirroring EY's pattern. Grant Thornton is the only brand with citation (12.5%) but zero current visibility, suggesting AI references its content without naming it in answers.
Google AI Mode is the sole engine recorded across all top brands, confirming this audit reflects a single-engine landscape. The top cited sources in the category are third-party aggregators and rankings platforms, specifically vault.com, insidepublicaccounting.com, clutch.co, and linkedin.com, rather than any CPA firm's own domain. This pattern indicates Google AI Mode is drawing its CPA firm references primarily from external list-style and directory content rather than from firm websites directly.

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 →
