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. 1 Enter your URL No signup. Any public page works. 2 Get your AEO score Overall score plus five per-engine sub-scores in ~30 seconds. 3 Fix what matters Impact-ranked recommendations, most valuable 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 1 ### Add JSON-LD Schema Markup Schema markup is the single most impactful AEO improvement. Use our [free Schema Generator](https://aeo.page/schema-generator/) to create Organization, Article, FAQ, and Product schema for your site. 2 ### 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](https://aeo.page/what-is-aeo/). 3 ### 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. 4 ### 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. 5 ### 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](https://aeo.page/aeo-vs-seo/) 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: 0–29 · Invisible Usually a crawler block or no structured data at all. Fixable in days, and the single biggest jump you will ever get. 30–54 · Typical Where most sites land. Schema exists but is thin; content is readable by humans but not cleanly extractable. 55–79 · Competitive You are being cited for some queries. Remaining gains come from entity authority and answer-block discipline. 80–100 · Cited by default 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. Beyond the document itself it checks delivery integrity: the page’s own dependencies — scripts, images and any content subdomain it pulls text from — are re-requested under a crawler identity, because a page that returns 200 while its subdomain returns 403 passes every access check and still reaches the engine incomplete. It fetches the same URL twice, once as a crawler and once as a browser, and compares visible text to catch differential serving that produces no error at all. It measures time-to-first-byte and which compression the server actually negotiates for a bot. It measures chunk fragmentation — how often continuous prose is interrupted by forms, promos, ad slots and recirculation rails, which is what produces unusable retrieval chunks. It checks the sentence answering each question heading for the hedged and passive openings that push the answer past where an extractor stops reading. And it validates the knowledge graph in both directions: not only that your sameAs resolves to a real Wikidata entity, but that the entity’s official-website property points back at your domain — a one-way link is the half an engine checks. ### 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. ### What does this AEO audit check that other tools do not? Five things, all measured live rather than inferred. **Partial delivery** — your page may be served to an AI crawler while its scripts, images or content subdomains are refused; a 200 on the document proves nothing about its parts, and asset rules are usually configured separately from the main site. **Differential serving** — the same URL fetched as a crawler and as a browser, compared on visible text, which catches content loss that returns no error at all. **Chunk fragmentation** — how often your main content is broken up by inline forms, promos and ad slots, because that is what makes retrieval chunks arrive half-formed. **Answer-lead directness** — whether the sentence under each question heading leads with the answer or delays it behind a hedge. **Reverse entity validation** — whether the Wikidata entity you link to links back to your domain, which is the direction that closes the trust loop. It also reports time-to-first-byte and the compression your server negotiates for bot requests. ### 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. ## Related Reading - → What is Answer Engine Optimization (AEO)? — the foundational concept - → AEO vs SEO: Which one matters more in 2026? - → How to Optimize for Perplexity — practical step-by-step guide - → The Ultimate Guide to AEO — comprehensive walkthrough - → AEO Case Studies — real-world wins and lifts ## Explore Our Other Free AEO Tools Take your AEO strategy further with our complete toolkit.
