At a glance
What we observed in this category
Kroll leads the corporate investigation firms category with a visibility score of 37.5%, more than 12 points above the next cluster of brands at 25.0%, and well above the category average of 8.1%. This gap is significant because Kroll rose from rank 13 to rank 1 in a single audit cycle, suggesting a sudden shift in how Google AI Mode surfaces the brand rather than gradual accumulation. Guidepost Solutions and FTI Consulting both sit at 25.0% visibility but trail Kroll by a meaningful margin on composite score.
Guidepost Solutions presents the clearest divergence between visibility and citation in this dataset. Its citation rate of 50.0% is the highest of any brand, yet its visibility sits at 25.0%, below Kroll. Conversely, Nardello and Co. holds 25.0% visibility with a 0.0% citation rate, meaning the AI names it without linking to its domain. This pattern suggests Google AI Mode distinguishes between brands it mentions as relevant and sources it trusts enough to cite as references.
Google AI Mode is the dominant engine across all ten ranked brands, with no brand recording a different top engine. The top cited sources list includes guidepostsolutions.com and third-party domains such as alphaapexgroup.com, worldmetrics.org, and corporateinvestigation.com, indicating that AI answers in this category pull from aggregator and directory-style sites alongside firm-owned domains. The presence of youtube.com and federal-lawyer.com in the citation pool further confirms that AI is not anchoring exclusively on firm websites.

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

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 →
