When buyers inquire about regulatory compliance consulting firms, AI engines frequently highlight EY as the leader with a visibility percentage of 75.0. Other top brands mentioned include Protiviti and KPMG. Their reputation in the business services sector makes them prominent choices in this category.
The rankings are shaped by references from authoritative sources such as acaglobal.com, jjccgroup.org, and regcompliancewatch.com. These websites often aggregate reviews and conduct industry assessments, providing AI with reliable data to inform its rankings. Protiviti's own site, also cited, reflects how a firm's direct content can influence visibility.
For buyers evaluating these rankings, it's crucial to consider factors AI engines emphasize, like recent reviews and third-party validations. Look for brands with consistent acclaim from trusted sources and proven expertise in your specific compliance needs to make an informed decision.
At a glance
What we observed in this category
EY leads the regulatory compliance consulting category with a visibility score of 75%, a full 25 points ahead of the four firms clustered at 50% (Protiviti, KPMG, PwC, and Deloitte). The category average visibility sits at just 15%, meaning EY is five times more visible than the typical brand in this set. Ten of the top brands audited hold zero visibility, which means the gap between leaders and the rest is not gradual but a hard cliff, making the top positions disproportionately valuable.
The visibility-to-citation relationship diverges sharply across brands. EY ranks first on visibility at 75% yet holds a 0% citation rate, the same as Deloitte at rank five. Protiviti, by contrast, matches its 50% visibility with a 50% citation rate, making it the most balanced brand in the set. This split shows that AI Mode names EY frequently in responses but does not anchor to its domain as a source, while Protiviti earns both mentions and direct source links.
Google AI Mode is the top engine for every brand in this audit, confirming it is the dominant surface for this category. The top cited sources list is notably populated by niche and specialist sites such as acaglobal.com, regcompliancewatch.com, and nmsconsulting.com, rather than Big Four domains. Protiviti is the only major consulting brand appearing directly in the cited sources list, which likely explains its unusually high citation rate of 50% relative to peers.

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 30 days and refresh this page automatically. How AI search ranking works →
