Executive summary
This benchmark report summarizes anonymized aggregate trends from AEOArc scans. It does not guarantee future rankings or AI mentions for any specific brand.
Methodology
Data is aggregated from anonymized free and paid scans across industries. No individual business data is published. Metrics include AI Visibility Score distributions, mention rates, citation patterns, and technical audit findings.
Key findings
Across monitored sites:
- Average AI Visibility Score varies significantly by industry
- Many sites block one or more AI search crawlers unintentionally
- Organization and FAQ schema are frequently missing
- Competitor citation gaps are common in local and B2B queries
- Technical AEO issues correlate with lower mention rates
Data highlights
Representative benchmarks (anonymized): ChatGPT mention rate median ~35%, Perplexity citation rate ~22%, blocked OAI-SearchBot ~18% of audited sites, missing FAQ schema ~62%.
Industry breakdown
Professional services, SaaS, and local businesses show the widest competitor citation gaps. Ecommerce brands often miss product schema signals AI systems use for recommendations.
Recommendations
Allow relevant AI search crawlers, publish organization + FAQ schema, monitor prompt clusters weekly, and track competitor citations — without expecting guaranteed AI placement.
How AI engines choose what to cite
Understanding retrieval behavior makes geo benchmarks practical instead of guesswork. AI answer engines retrieve heading-bounded passages of roughly 150–600 words — not whole pages — so each section of your site must stand alone as a complete answer. Peer-reviewed research (Princeton GEO, KDD 2024) measured that adding credible citations, concrete statistics, and expert quotations lifted content visibility in generative answers by 28–41%, while keyword stuffing reduced it. Citation patterns are also volatile: industry studies observed 40–60% of cited domains changing within a single month, and fewer than 15% of cited domains overlap between ChatGPT and Perplexity for the same question. The practical takeaway: publish answer-first sections with real evidence, keep AI search crawlers (like OAI-SearchBot and PerplexityBot) unblocked, and measure repeatedly across engines rather than trusting any single snapshot.
- Write answer-first sections that stand alone (150–600 words each)
- Back claims with citations, statistics, and quotations — the proven GEO levers
- Allow AI search crawlers in robots.txt; block only training bots if you choose
- Measure across multiple engines and dates — single checks are noise

Expert perspective
"AI search visibility is not a single ranking — it is citation frequency across hundreds of prompts. Teams that dogfood LLMO, GEO, and AEO together win faster than those chasing one acronym." — AEOArc Editorial Team
