Original research on how consultants, accountants, advisors, agencies, and other professional services firms appear across Google, AI Overviews, ChatGPT, Gemini, Claude, Perplexity, and high-intent buyer search.
Key findings
The public page is designed for journalists, analysts, newsletters, and industry operators. Findings stay tied to the benchmark sample and collection window.
ChatGPT (52.5%) is far more likely to steer users toward hiring a professional than Claude (35%) or Gemini (30%), meaning the same query can yield very different framing depending on which assistant is used.
Claude (50%) frequently interrogates the user's situation before answering, versus 25% for ChatGPT and 0% for Gemini — a sharp behavioral split that affects whether firms get mentioned in follow-up turns.
Gives_selection_criteria_list ranges from 32.5% (chatgpt, gemini) to 45% (claude), showing this is one of the most consistent structural elements across models — a prime slot for firms to be referenced as exemplifying good criteria.
Claude flags red flags/scams in 27.5% of answers versus 10% for ChatGPT and 15% for Gemini, indicating Claude answers skew more toward risk-avoidance framing in professional services queries.

About this benchmark
This report measures how visible professional services brands are across AI-generated search and recommendation environments, with attention to mentions, recommendations, citations, source quality, sentiment, trust evidence, and hallucination risk.
Measures whether AI systems recognize brands organically and where they appear inside generated recommendations.
Separates brand-owned websites, directories, media, review platforms, regulatory sources, and uncited assertions.
Checks whether public evidence supports safer descriptions, comparisons, and recommendations in high-intent searches.
AI-visible brands
Rankings are only shown when verified public data exists. The language is intentionally visibility-based, not a claim that one company is objectively better than another.
