## Questions and answers

### How does an AI visibility audit work?

The audit runs multiple queries against different AI models to measure how often your brand is cited. It compares raw model outputs against processed responses to identify hallucinations. The result is a proxy score reflecting your citability across engines.

### Why do AI models hallucinate brand names?

Models fabricate sources when they cannot find machine-readable, canonically anchored entities. Familiarity with a brand name can lead to confident but false attributions. This is known as the brand hallucination paradox.

### Is AI visibility the same as SEO?

No, AI visibility is stochastic while SEO is deterministic. AI answers do not generate logged clicks or impressions. Optimization focuses on how models synthesize answers rather than ranking algorithms.

### What is the PEBM study?

The Per-Entity Bias Map analyzed 1,400 runs on 100 Hungarian B2B companies. It found that over 45% of cited sources were fabricated overall. High-awareness firms saw higher fabrication rates than low-awareness ones.

### Can I fix my AI visibility score?

Improvement requires creating machine-readable, canonically anchored entities for AI models. This involves structured data and clear definitions rather than traditional backlink strategies. The audit identifies specific gaps in your current setup.

### Do paid placements improve AI visibility?

Current research suggests a correlation between paid access and appearance but not necessarily causation. The pay-to-appear hypothesis remains under investigation. True visibility relies on accurate entity reconstruction.

## Articles

- [What a Quick AI-SEO Audit Tool Actually Checks](https://aiseoaudittool.hu/articles/what-a-quick-ai-seo-audit-checks/): A quick AI-SEO audit tool checks your website's structural hierarchy, paragraph length, readability scores, schema markup, and technical crawlability to determine if AI systems can parse and cite your content. It evaluates specific signals like heading logic, entity density, and robot permissions but cannot verify the accuracy of your claims or your off-site reputation. The result is a triage report that highlights structural gaps rather than a guaranteed ranking prediction.
- [Audit Tool vs Manual Check: Where a 70/100 Score Misled](https://aiseoaudittool.hu/articles/audit-tool-vs-manual-check/): Yes, an AI SEO audit tool can assign a high score to a site that AI bots cannot access. This occurs when the tool reads the robots.txt file text but fails to simulate actual bot requests, missing HTTP 403 errors returned by the server to specific user agents like GPTBot or ClaudeBot.
- [Spot-Checking an Audit Tool's Findings by Hand](https://aiseoaudittool.hu/articles/spot-check-audit-findings-by-hand/): You verify audit findings by manually sending requests to your server using specific bot user agents like GPTBot and ClaudeBot to check for HTTP status codes. You must also compare the raw HTML source against the fully rendered browser view to ensure content is visible to crawlers. Finally, cross-check conflicting metrics within the report itself, such as internal link counts or sector classifications, to identify logic errors.
- [Sanity Checks for an Automated AI-SEO Report](https://aiseoaudittool.hu/articles/sanity-checks-for-audit-reports/): An automated AI-SEO report is unreliable if its internal counts contradict each other, its sector classification mismatches benchmarks, or its score arithmetic exceeds the scale. You must verify that the tool actually tested bot access via HTTP requests rather than just reading text files, and confirm that word counts remain consistent across different sections.
- [From Audit Report to Fix List: Prioritizing by Impact](https://aiseoaudittool.hu/articles/from-audit-report-to-fix-list/): Fix access blockers first, such as contradictory robots.txt settings or broken AI-specific files like llms-full.txt, because these prevent indexing entirely. Next, resolve contradictory signals where HTTP headers block access while metadata permits it. Finally, address enrichment gaps like missing images or incomplete structured data to improve ranking potential.
- [What Automated AI-SEO Tools Cannot See: Structural Blind Spots](https://aiseoaudittool.hu/articles/what-automated-tools-cannot-see/): Automated AI-SEO tools cannot verify if AI crawlers like GPTBot or ClaudeBot can actually access your pages, nor do they measure if your brand appears in generated answers. They rely on static code reading rather than live network requests, missing critical access blocks and sector-specific citation failures that determine real visibility.
- [AI-SEO Tools in CEE: What Users Actually Complain About](https://aiseoaudittool.hu/articles/ai-seo-tool-landscape-cee/): Users in Central Europe primarily rely on established platforms like Semrush AI, Surfer, and emerging tools such as SeoZing and SubSEO for content optimization. These tools consistently miss the ability to track and optimize for Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO), leaving brands invisible in AI-generated responses. No current automated solution in the region handles the specific requirements of LLM visibility or Reddit-based authority signals.
- [Can ChatGPT or Claude Audit Your Website for AI SEO?](https://aiseoaudittool.hu/articles/can-an-llm-audit-your-site/): You can use ChatGPT or Claude to draft audit checklists and analyze pasted code, but they cannot access live websites to verify current rankings or citations. These models often invent findings because they lack real-time browsing capabilities and rely on training data rather than live site inspection. A reliable approach combines AI drafting with human verification and specialized tools that measure actual AI visibility.
- [AI-SEO Audit Report Terms Explained: A Practical Glossary](https://aiseoaudittool.hu/articles/audit-report-glossary/): Terms in an AI-SEO audit report measure how well a website's structure, content, and code allow large language models to parse, extract, and cite information. Key metrics include chunk scores for paragraph length, readability grades for linguistic complexity, and structural signals like schema markup that guide AI crawlers. These scores determine whether a site is classified as AI-Native, AI-Ready, or AI-Invisible.
- [The Free AI Visibility Quick Audit: Scope and Limits](https://aiseoaudittool.hu/articles/free-quick-audit-in-preparation/): A dedicated free tool to check how AI assistants see your brand is currently in preparation on this hub. It will run live bot requests to verify actual access and analyze seven structural dimensions, but it will not replace a full manual audit for complex entity conflicts or external platform status.
- [Escalation Checklist: When a Quick AI Audit Is Not Enough](https://aiseoaudittool.hu/articles/when-a-quick-audit-is-not-enough/): You need a full AI visibility audit when operating in regulated sectors, when AI answers present conflicting facts about your brand, or when competitors dominate citations while you remain invisible. Quick tools cannot resolve complex entity conflicts, verify person-centered expertise, or navigate multi-language market nuances.
- [AI-SEO Audit Tool FAQ: Accuracy, Frequency and Data](https://aiseoaudittool.hu/articles/ai-seo-audit-tool-faq/): Run an automated AI-SEO audit monthly to track structural changes, but schedule a full manual verification quarterly or after major site updates. Tools provide a consistent baseline for metrics like heading counts and schema presence, yet they often miss critical live server responses from AI crawlers like GPTBot. Use the tool report as a triage list, not a final verdict on your site's visibility.
