FAQ

Frequently Asked Questions

Common questions about AI visibility measurement for tax advisory and CPA firms.

How is AI visibility measured for tax advisory firms? +
ProCloser.ai's TrustRank™ methodology scores firms by running hundreds of natural-language queries across ChatGPT, Perplexity, Google AI Overviews, and Claude — the platforms that now drive high-intent professional services discovery. We track mention frequency, recommendation position, and query category breadth, then normalize scores on a 0–100% scale. Scores are updated quarterly to reflect the evolving AI search landscape.
Why do Big 4 firms dominate AI results? +
Big 4 firms have decades of authoritative web content — published research, client alerts, regulatory commentary, and thought leadership — that AI models ingest during training and retrieval. Their brand authority signals and the sheer volume of third-party citations mean they are surfaced by default for broad tax queries. The good news: smaller firms can compete effectively by building deep niche authority in specific practice areas where the Big 4's content is less targeted and less specific.
What is TrustRank™? +
TrustRank™ is ProCloser.ai's proprietary AI search visibility scoring system. It measures how frequently and prominently a firm is recommended by major AI platforms — ChatGPT, Perplexity, Google AI Overviews, and Claude — across a panel of 200+ natural-language queries representative of how real prospects research professional services. A score of 90%+ indicates dominant AI presence; 70–89% indicates strong niche visibility; below 70% suggests significant room for AI search optimization. The methodology weights query categories by business value and accounts for recommendation position, not just mention frequency.
How can my CPA firm improve AI visibility? +
Improving AI visibility for a CPA or tax advisory firm requires a structured approach: (1) Publish authoritative, question-answering content that directly addresses the prompts your ideal clients use — answers structured the way AI can cite them. (2) Build E-E-A-T signals — credentials, case studies, client testimonials, and author bios with professional credentials like CPA, EA, JD. (3) Earn structured citations from directories, professional associations, and industry publications that AI models trust. (4) Optimize your technical footprint so AI crawlers can access and index your content without barriers. ProCloser.ai specializes in all four pillars for tax advisory firms.
