What is an AEO audit tool?
An AEO audit tool analyzes your website and scores how likely AI answer engines are to cite it. Where a classic SEO audit measures your fitness for Google's ranked links, an AEO audit measures the three things that decide whether ChatGPT, Perplexity, Gemini, and AI Overviews quote you: machine-readable structured data, answer-first content an LLM can extract, and crawler access for the AI bots that build those answers.
This free AEO audit runs in about 30 seconds. Enter a URL and the tool returns a 0–100 AEO score, five sub-scores (schema, content structure, and ChatGPT / Perplexity / Gemini readiness), and a prioritized list of fixes ranked by impact — so you know exactly what to change first.

What Does the AEO Audit Check?
Schema Markup Score
Analyzes your JSON-LD structured data — Organization, Article, Product, FAQ, HowTo schema. Checks for completeness, accuracy, and AI-optimization of each schema type.
Content Structure Score
Evaluates heading hierarchy, answer-first formatting, FAQ sections, content length, readability, and whether your content structure enables easy AI extraction.
ChatGPT Readiness
Checks if ChatGPT can effectively crawl, understand, and cite your content. Evaluates robots.txt access, content clarity, and citation-worthiness.
Perplexity Readiness
Analyzes how well your content aligns with Perplexity's citation model. Checks for factual density, source authority, and structured answers that Perplexity prefers.
Gemini Readiness
Evaluates your content's compatibility with Google Gemini and AI Overviews. Checks for E-E-A-T signals, content freshness, and Google's structured data requirements.
Actionable Recommendations
Get prioritized, specific recommendations to improve your AEO score. Each suggestion includes implementation guidance ranked by impact.
How to Improve Your AEO Score
Add JSON-LD Schema Markup
Schema markup is the single most impactful AEO improvement. Use our free Schema Generator to create Organization, Article, FAQ, and Product schema for your site.
Restructure Content for AI Extraction
Use answer-first formatting: start each section with a clear, concise answer then elaborate. Learn more in our What is AEO guide.
Add FAQ Sections to Key Pages
FAQ sections with FAQPage schema directly match how users query AI assistants and are among the most frequently cited content types.
Allow AI Crawler Access
Check your robots.txt to ensure ChatGPT-User, PerplexityBot, and Google-Extended crawlers can access your content. Blocked crawlers mean zero AI citations.
Build Authority Signals
Add author bios with credentials, include data citations, display publication dates, and ensure E-E-A-T signals are visible. Read our AEO vs SEO guide for the full framework.
AEO audit vs SEO audit: what actually differs
The two audits overlap on crawlability and page speed, then diverge completely. An SEO audit asks "will this page rank?" An AEO audit asks "will a model quote this page, and will it attribute the quote to you?" A site can pass an SEO audit comfortably and still be invisible inside AI answers, because the signals that get you extracted are not the signals that get you ranked.
| Dimension | Traditional SEO audit | AEO audit |
|---|---|---|
| Goal | Rank a blue link | Be cited inside the answer |
| Unit of success | Position for a keyword | Citation share across engines |
| Content shape | Long-form, keyword coverage | Answer-first blocks a model can lift whole |
| Structured data | Nice-to-have for rich results | Load-bearing — it is how the entity is understood |
| Crawler access | Googlebot, Bingbot | GPTBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended |
| Authority signal | Backlinks | Corroboration — being consistently stated across sources |
| Failure mode | Page 2 | Answered about, without attribution |
This is why a separate AEO audit tool exists at all. If AI readiness were a subset of SEO, your existing
SEO crawler would already report it — and it does not, because it never checks whether
GPTBot is allowed or whether your key
claims survive extraction without their surrounding paragraph.
How the AEO score is calculated
The overall 0–100 score is a weighted composite of five sub-scores. The weighting reflects what actually moves citation rates, not what is easiest to measure — schema and crawler access are weighted highest because they are binary gates: fail them and nothing downstream matters.
Schema markup
30%Presence, validity and completeness of JSON-LD — Organization, Article, Product, FAQPage, HowTo. Checks that entities resolve and that required properties are populated rather than merely present.
AI crawler access
25%Whether robots.txt, WAF rules and edge policy permit the agents that build answers. The single most common silent failure — many sites block GPTBot without knowing it, usually via a bot-protection default.
Content structure
25%Heading hierarchy, answer-first paragraphs, self-contained 120–180 word blocks, question-shaped subheadings, and FAQ formatting. Measures whether a model can lift a passage without losing its meaning.
Per-engine readiness
20%Separate sub-scores for ChatGPT, Perplexity and Gemini, because they weight signals differently — Perplexity leans on freshness and source diversity, Gemini on entity grounding, ChatGPT on structured clarity.
What counts as a good AEO score?
Most sites score far lower than their owners expect on a first audit, because AEO signals were never part of anyone's launch checklist. Use these bands to read your result:
Usually a crawler block or no structured data at all. Fixable in days, and the single biggest jump you will ever get.
Where most sites land. Schema exists but is thin; content is readable by humans but not cleanly extractable.
You are being cited for some queries. Remaining gains come from entity authority and answer-block discipline.
The engines treat you as a reference for your topic. Focus shifts from earning citations to defending them.
The manual AEO audit checklist
If you would rather audit by hand — or want to verify what the tool reports — this is the same sequence the audit runs, in priority order. Work top-down and stop when you run out of time; the list is ordered by impact, not by effort.
- Confirm AI crawlers are allowed. Check robots.txt for GPTBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended — then verify at the edge, because a WAF or bot-protection rule can block them even when robots.txt permits.
- Validate your structured data. Every key page should carry valid JSON-LD with populated required properties, not an empty shell.
- Test extraction. Take any 150-word block from a key page and read it alone. If it no longer makes sense without the paragraph above it, a model cannot quote it either.
- Make subheadings question-shaped. Headings that match how people actually ask give the model an obvious answer boundary.
- State your entity consistently. Same name, same description, same category everywhere — models corroborate across sources before attributing.
- Add an llms.txt. A plain-text map of what you want models to use and how to attribute it.
- Check freshness signals. Visible and machine-readable dateModified; Perplexity in particular discounts undated content.
- Ask the engines directly. Search your top 20 queries in ChatGPT, Perplexity and Gemini, and record who gets cited instead of you.
Frequently Asked Questions
What is an AEO audit?
An AEO audit analyzes how well your website is optimized for AI search engines like ChatGPT, Perplexity, Google Gemini, and Claude. It checks schema markup, content structure, authority signals, and crawler access to calculate your readiness for AI-generated citations.
What does the AEO audit tool actually check?
The audit runs 35+ checks against a live fetch of the URL you enter — nothing is pre-computed. It first detects what kind of page it is across 17 content profiles, then scores it only against signals that apply to that type, so a news article is never marked down for lacking Product schema. It sends a real GPTBot request to detect CDN, WAF and bot-rule blocks that robots.txt cannot reveal; renders the page in headless Chromium and compares that against the raw HTML to find content that exists only after JavaScript runs; queries Wikidata to confirm your brand entity actually resolves rather than merely that sameAs is present; and validates sameAs against Wikidata, Wikipedia, Crunchbase, VIAF, ISNI, ORCID, ROR and GLEIF. It scores freshness in days against per-page-type thresholds, and measures extractability — where your key facts sit, whether the answer appears in the opening 150 words, whether headings are phrased as questions, and list, table and quote density.
How is the AEO score calculated?
The AEO score is a weighted average of five sub-scores: Schema Markup (how well your structured data is implemented), Content Structure (heading hierarchy, answer formatting, FAQ sections), ChatGPT Readiness, Perplexity Readiness, and Gemini Readiness. Each is scored 0-100.
Is the AEO audit really free?
Yes, completely free with no credit card required. You get a full AEO score breakdown, sub-scores for each AI platform, and prioritized recommendations. Enter your email optionally to receive a detailed PDF report.
What is a good AEO score?
Scores above 80 indicate strong AEO optimization. Most websites score between 20-40 on their first audit. The average score across all industries is 34. Top-performing sites in competitive niches typically score 75-95.
How often should I run an AEO audit?
We recommend running an AEO audit monthly or after any major content or technical changes. AI search algorithms evolve rapidly, and regular audits help you maintain and improve your AI visibility.
Is this a free AEO audit tool, or a trial?
It is a genuinely free AEO audit tool — not a trial and not a teaser. You get the full score, all five sub-scores and the complete prioritized fix list on screen. There is no paywalled section of the report.
What should I look for in an AEO checking tool?
Three things separate a real AEO checking tool from a repackaged SEO crawler. First, does it verify AI crawler access at the edge rather than only reading robots.txt? Second, does it score per engine, since ChatGPT, Perplexity and Gemini weight signals differently? Third, does it test whether your content survives extraction — a passage that only makes sense in context cannot be quoted.
How is this different from an SEO audit tool?
A traditional SEO audit tool grades you for Google's ranked blue links — keywords, backlinks, Core Web Vitals. An AEO audit tool grades you for being cited inside AI answers: structured data an LLM can parse, answer-first content it can extract, and crawler access for ChatGPT-User, PerplexityBot, and Google-Extended. This tool scores both the technical and content signals that decide whether AI engines quote you.
