Do you trust AI assistants to provide unbiased recommendations for local professional services?
Research from Expert Press found that AI assistants disproportionately recommend a small concentration of accounting firms, with 25 firms capturing 87.2% of all recommendations. These findings suggest that AI visibility is increasingly decoupled from a firm's actual volume of business.
Why it matters
AI models prioritize firms with websites that feature detailed regional descriptions, specific service lists, and recent updates. Busiest firms are losing out on automated referrals simply by failing to list their operating locations online.
AI assistants generated 3,480 total answers, with the top 10 firms securing 61.3% of all recommendations. In a separate study, the six least busy firms received 184 recommendations in August, while the firm with the most actual audit clients received zero.
The players
Expert Press
A research group that conducted the national study on AI referral patterns across 3,480 queries.
AIWorthy
A firm that tested accounting practice visibility in a North Carolina region using 500 total AI queries.
Accounting Today
A major industry publication that released the research findings concerning AI search biases.
The details
AI models aggregate data from business directories, government records, and LinkedIn to build their referral lists. Firms that actively maintain their website's local SEO and content depth are being surfaced by AI queries over competitors that rely solely on established industry reputation or large client rosters. This creates a disconnect where firms with fewer audits can significantly out-perform their larger rivals in digital referral volume.
Timeline
August 2026: AIWorthy conducted 250 AI tests for its regional study.
September 2026: AIWorthy conducted 250 additional AI tests.
October 7, 2026: Accounting Today published the findings from both research studies.
Market Landscape
This development marks a departure from traditional word-of-mouth referral networks, where firm reputation was historically built on client volume rather than digital information density. The Expert Press study demonstrates that AI discovery is now the primary gatekeeper, prioritizing website content over historical performance metrics.
Owners should prioritize listing operating locations, service areas, and recent firm updates on their websites to improve AI search visibility. Audit volume is not a proxy for digital discovery, so even large firms must ensure their technical SEO accounts for how AI tools source business information.
The takeaway
Your website's structural data is now a more important lead generator than your actual client list for AI-driven discovery. Update your homepage to explicitly name your service regions and list your core service offerings in a machine-readable format.
