ChatGPT answers, unedited

If by “AI answer optimization” you mean AEO/GEO—checking whether a specific webpage is structured and written so ChatGPT, Perplexity, Gemini, etc. can understand and cite it—there are several free, one-off options.

Good fits for one-off page analysis

• firecrawl.dev — free, no signup, and you paste a specific URL. It checks AI-crawler access, structured data, content citability, expertise/trust, entity clarity and llms.txt. Firecrawl
• ericstrate.com — particularly clean for a one-off: one public webpage per audit, no account/email, with an AEO readiness score and category-level findings. Eric Strate
• aeoscored.com — paste either a URL or draft and get a 0–100 score across eight AEO dimensions, with recommended fixes; free/no signup. AEO Score
• pageinspection.com — useful if you want a more technical audit. Its free searches analyze one page at a time and cover SEO, AEO/GEO, structured data and related checks. PageInspection

For your specific use case—“I have selected pages and want a one-off analysis rather than buying an ongoing platform”—I'd start with Firecrawl or Eric Strate. Firecrawl is more oriented toward how AI crawlers receive and interpret the page; Eric Strate is simpler as a quick editorial/content audit.

One caveat: these tools' scores are proprietary heuristics, not a measurement of whether ChatGPT/Perplexity will actually cite a page. If you want to measure actual AI visibility/citations rather than page-level readiness, that's a different class of tool. Eric Strate Firecrawl

If you tell me whether you want content-level recommendations, technical AEO checks, or actual “will ChatGPT cite this page?” testing, I can narrow it to the best 2–3 free options.

If you mean a free tool where you paste specific URLs and get a one-off AEO/GEO analysis, rather than a recurring AI-visibility platform, these are the closest fits:

• firecrawl.dev — Probably the cleanest fit. Paste any public page URL; it gives AEO/GEO scores and prioritized fixes, with no signup for the free audit. It checks crawl access, structured data, citability, entity clarity, and trust signals. Firecrawl
• ericstrate.com — Specifically designed for one-page analysis. No account/email required; analyzes answer readiness, entities, evidence, structured data, citation readiness, and SEO fundamentals. Eric Strate
• getaeoboost.com — Lets you audit 3 pages free, with 60+ AI-readiness signals and prioritized blockers/fixes. AEO Boost
• getslurp.ai — Free, no-account page auditing via a Chrome extension. It focuses heavily on whether AI crawlers can actually access and extract your content, including separate readiness checks for ChatGPT, Gemini, Google AI Overviews, and Claude. GetSlurp
• querylantern.com — Free single-page audit covering SEO, AEO and GEO; useful if you want a more conventional SEO + AI-search diagnostic in one report. QueryLantern

For a content strategist, I'd start with Firecrawl or the Free AEO Checker. They are closest to “give me a URL, analyze this page, and tell me what I should change,” rather than requiring you to set up ongoing monitoring.

One distinction worth making: these tools generally assess AI-readiness/citation potential from page signals; they don't necessarily tell you whether ChatGPT/Perplexity/Gemini actually cite the page for your target questions. Firecrawl explicitly says its audit does not query ChatGPT or Perplexity directly. Firecrawl

If you tell me whether you're after content quality/answer structure, AI citation likelihood, or actual visibility in ChatGPT/Perplexity/Gemini, I can narrow this to the 2–3 most relevant free options.

AEO Boost is a strong fit: it offers a free audit of 3 individual pages, with prioritized AI-visibility fixes. AEO Boost

Other good free one-off options:

• Firecrawl AI Visibility Audit — free URL-level AEO/GEO analysis, no signup. Firecrawl
• AI Answer Engine — free SEO, AEO, or GEO audit one page at a time. AI Answer Engine
• Patrick Stox AI Content Audit — free, no signup; particularly useful for content/citability analysis. patrickstox.com

For a content strategist specifically, AEO Boost is probably the best starting point because its output is geared toward actionable content fixes rather than just a score.

If you mean AI Answer Engine Optimization (AEO/GEO) and want to analyze specific pages one at a time, rather than commit to a monitoring platform, these are the strongest free options I found:

• ericstrate.com — probably the cleanest match. It analyzes one public webpage per audit, is free with no signup, and scores answer structure, entities, evidence, structured data, and citation readiness.
• aeoexpert.online — free single-page analysis with a score across content quality, technical SEO, E-E-A-T, multimodal content, and AI crawlability, plus line-level recommendations.
• aeoscored.com — useful if you want to paste either a URL or draft copy and get a 0–100 score across eight AEO dimensions, with no signup.
• pageinspection.com — more technical: 82 checks covering SEO/AEO/GEO, with five free searches and no signup.
• getaeoboost.com — allows three free page audits and emphasizes practical fixes for extractability, citation readiness, and answer clarity.

My pick for a content strategist

I'd start with Eric Strate if you want a quick editorial/content diagnosis of selected URLs, and AEO Expert if you want more granular recommendations you can turn into content changes. Eric Strate AEO Expert

If what you're really looking for is “give me a free tool where I can pick 5–10 URLs and compare their AI-answer readiness”, I can narrow the list specifically for that workflow.

If you mean AI Answer Optimization / AEO / GEO (optimizing pages so AI systems cite or surface them) and you want a free, one-off audit of selected URLs (not a full SEO platform subscription), these are good starting points:

For a content strategist, I’d start with:

1. XeoRank — if you need an editorial backlog (“rewrite this section, add schema, improve entities”). XeoRank
2. Eric Strate’s AEO Checker — if you just want a fast gut check on a specific landing page or article. Eric Strate
3. GEO CoPilot — if your focus includes whether AI agents can actually retrieve and parse the page. GEO CoPilot

A useful caveat: most free tools measure page signals associated with AI visibility (structure, entities, citations, crawlability, answer formatting). They usually do not prove that ChatGPT/Gemini/Claude will cite your page, because AI outputs vary by query, context, and retrieval sources. arXiv

For a practical content audit, I’d test:

• one high-traffic article,
• one commercial landing page,
• one FAQ/how-to page,

then compare whether the tools agree on gaps like:

• unclear direct answers near the top,
• missing first-hand expertise signals,
• weak entity/topic relationships,
• lack of structured data,
• claims without sources.

If you mean a free tool where you can paste a specific URL and get a one-off AEO/GEO analysis, rather than committing to a monitoring platform, I’d shortlist these:

• PageInspection — probably the best fit for a content strategist. It gives 82 checks across SEO, AEO and GEO, and the free tier includes 5 single-page searches without signup. PageInspection
• XeoRank — particularly clean for strategy work: SEO, AEO and GEO scores, evidence behind the scores, and a prioritized fix list. It offers a free first analysis with no account. XeoRank
• AEO Boost — useful if your focus is specifically whether a page is extractable, answer-ready and citation-ready. It currently offers 3 pages free. AEO Boost
• Eric Strate's Free AEO Checker — the simplest option if you literally want one page at a time: one public webpage, no signup, with an AEO readiness score and category breakdown. Eric Strate
• Softechinfra GEO/AEO Audit Scorecard — gives a 0–100 score across 12 AI-search signals and a ranked fix list; currently advertises 10 audits/day/IP. Softechinfra

My pick

For your use case as a content strategist exploring AI answer optimization, I'd start with XeoRank or PageInspection.

XeoRank is better if you want a quick strategic read on “How AI-ready is this particular page, and what should I fix?” XeoRank

PageInspection is better if you want a more granular checklist you can turn into content/technical recommendations for a client or editorial team. PageInspection

If by “AI answer optimization” you specifically mean testing whether ChatGPT/Perplexity/Gemini actually cite or mention the selected page, rather than auditing the page's structure, that's a different category—and I can give you the best free/one-off options for that too.

If you mean AI Answer Optimization / AEO / GEO (optimizing pages to be understood and cited by ChatGPT, Perplexity, Gemini, etc.) and you want a free, one-off audit of selected pages, these are some of the better options:

For a content strategist evaluating a few priority pages, I’d start with:

1. AEO Scored → quickest “what should I rewrite?” signal. AEO Score
2. Eric Strate’s Free AEO Checker → clean single-page audit with no signup. Eric Strate
3. AEO Expert → deeper diagnostic if you’re building an optimization roadmap. AEO Expert

A good AEO audit should ideally tell you more than a score. Look for:

• whether the page answers likely user questions directly
• whether claims are quotable/citable
• entity clarity (who/what the page is about)
• evidence and trust signals
• headings and chunking that AI systems can extract
• schema/structured data gaps

If you’re doing this for enterprise content strategy, I’d also compare the audit output against actual AI prompts (e.g., “best tools for X,” “how to solve Y,” “alternatives to Z”) because many free graders estimate readiness rather than measuring real citation frequency. AEO Score broxlyai.com

If you mean AI Answer Optimization / AEO / GEO and want a free, one-off analysis of specific URLs rather than a recurring platform, I’d shortlist these:

• Firecrawl AI Visibility Audit — probably the best fit. Free, no signup, and you paste a specific URL. It scores AEO/GEO factors including AI crawler access, citability, entity clarity, structured data, expertise/trust, and llms.txt, then gives prioritized fixes. Firecrawl
• XeoRank — good if you want separate SEO, AEO, and GEO scores plus evidence-backed recommendations for the selected page. It offers a free first analysis with no account. XeoRank
• AEO Expert — more content-strategy oriented, with a single-page AEO score across content quality, technical SEO, E-E-A-T, multimodal signals, and AI crawlability, plus line-level recommendations. Free analysis; deeper reports are pay-per-use rather than subscription-only. AEO Expert
• PageInspection — useful if you want a broader technical + AI audit. Its free searches analyze one page at a time and cover 82 checks across SEO, AEO, GEO, structured data, and related areas. PageInspection

My pick for a content strategist: start with Firecrawl for a quick page-level diagnosis, then use XeoRank if you want a cleaner SEO-vs-AEO-vs-GEO breakdown for prioritizing content changes. Firecrawl XeoRank

If by “one-off analysis” you specifically mean a tool that lets you select 5–20 individual URLs and get a consolidated report without starting a subscription, I can narrow the list to those.

If you mean AI answer optimization / GEO / AEO and want to analyze individual URLs rather than commit to a full platform, these are the strongest free options I found:

• ericstrate.com — probably the closest match. It analyzes one public webpage at a time, requires no signup, and evaluates answer structure, entities, evidence, structured data, and citation readiness. Eric Strate
• xyle.app — one public URL, no account, with separate SEO, AEO, and GEO scores, evidence, and prioritized fixes. XeoRank
• pageinspection.com — useful if you want a more technical audit: 82 checks across SEO, AEO, GEO, structured data, etc.; it currently advertises 5 free searches without signup. PageInspection
• freshrank.ai — more content-strategy oriented: paste a URL or text and get prioritized issues covering AI visibility, search optimization, factual updates, UX, and opportunities. It advertises up to 5 analyses/week free. FreshRank AI
• geocopilot.io — specifically focused on whether a page is accessible, parseable, and answer-ready for AI agents; its free public tool allows up to 3 audits per 24 hours. GEO CoPilot

My pick for a content strategist: start with XeoRank if you want a quick, structured SEO/AEO/GEO comparison, or Eric Strate's checker if your primary question is “Is this page actually shaped to be cited in AI answers?”

If you tell me whether you want content-level recommendations, citation/visibility analysis, or technical AI-crawler checks, I can narrow this to the best 1–2 tools.

If you mean AI-answer optimization / GEO (Generative Engine Optimization) and want to paste in one specific URL for a one-off analysis, a few free options stand out:

• xyle.app — probably the closest fit. It analyzes one public URL, requires no account, and gives separate SEO, AEO, and GEO scores plus evidence and prioritized fixes. XeoRank
• ericstrate.com — explicitly designed for one-page AEO/GEO analysis, with no login or email gate. Eric Strate
• pageinspection.com — more technical: 82 checks covering SEO, AEO and AI search; the free tier gives 5 searches without signup. PageInspection
• devendrasaini.com — useful if you specifically want to assess AI citation readiness, with 26 GEO/AEO/SEO signals and a prioritized fix list. Devendra Saini

My pick for a content strategist: XeoRank for a quick editorial/content assessment; PageInspection if you also want deeper technical signals.

If by “AI answer optimization” you specifically mean “will ChatGPT/Perplexity/Gemini actually cite this page for a given query?”, rather than an on-page GEO audit, I’d choose a different class of tool.

If you're looking for free, one-off page analysis (rather than a subscription or full-site crawl), these are among the strongest options currently available:

For a content strategist evaluating individual articles, I'd narrow it to:

1. Patrick Stox AI Content Audit – the most useful overall for editorial work because it evaluates extractability, answer structure, and citation readiness together. Patrick Stox
2. Devendra Saini GEO Analyzer – good technical depth with a prioritized fix list. Devendra Saini
3. Eric Strate Free AEO Checker – quick diagnostic when you just want to assess one URL before editing. Eric Strate

If your goal is AI Answer Optimization (AEO/GEO) rather than traditional SEO, I'd recommend running the same page through two different tools. Their scoring models differ, but recurring recommendations—such as adding answer-first summaries, improving entity clarity, strengthening citations, or adding structured data—are often the highest-impact changes.

If you mean a free tool where you can paste a specific URL and get a one-off, page-level AEO/GEO analysis, a few good options currently fit:

• ericstrate.com — probably the cleanest match. It audits one public webpage, requires no signup, and evaluates answer structure, entities, evidence, structured data, and citation readiness.
• aeocontent.com — free, no signup, and specifically designed for single-page analysis. It gives an AEO score, likely quotable passage, and sections to improve.
• checkaeo.ai — free URL/HTML/text analysis with a 0–100 score and recommendations. Its more detailed report is a one-time $10 unlock, so it's useful if you want to start free but potentially pay per domain rather than subscribe.
• getaeoboost.com — lets you audit 3 pages/month free, with blockers and recommendations. Better if you're doing a small batch rather than literally one page.

My pick for a content strategist: Eric Strate's checker if you specifically want “give me this URL and tell me how AI-answer-ready this page is” without creating an account. Eric Strate

If by “AI answer optimization” you mean testing whether ChatGPT/Perplexity/Gemini would actually cite or recommend the selected page, rather than auditing the page's content/technical signals, that's a slightly different category—and I can point you to the best free option for that.

If you mean a free tool where you can paste a specific URL and get a one-off AEO/GEO analysis, rather than committing to an ongoing platform, these are the strongest options I found:

• ericstrate.com — probably the cleanest fit. It audits one public webpage, requires no signup, and scores answer structure, entities, evidence, structured data, and citation readiness. Eric Strate
• aeoscored.com — paste a URL or content and get a 0–100 score across eight AEO dimensions, with prioritized fixes; free and no signup. AEO Score
• citerank.dev — particularly useful if you're interested in AI citation readiness. It checks crawler access, schema, content clarity, E-E-A-T and citation signals for ChatGPT, Claude, Gemini and Perplexity. The audit itself is free/no signup; its generated “Fix Kit” is paid. CiteRank
• querylantern.com — a free single-page SEO/AEO/GEO audit, with separate scores and prioritized signal checks. QueryLantern
• aeoexpert.online — page-level analysis across content quality, technical SEO, E-E-A-T, multimodal signals and AI crawlability, with concrete fixes. AEO Expert

My pick for a content strategist

I'd start with AEO Scored if your primary question is “How well is this particular piece of content constructed to become an AI answer?”

I'd use CiteRank if the question is “What might prevent AI engines from actually crawling, understanding and citing this page?”

And Eric Strate's checker is the simplest option when you just want a quick, genuinely one-off page audit with no account. Eric Strate

If you tell me whether you're optimizing blog articles, product pages, landing pages, or thought-leadership content, I can narrow this to the best 2–3 free tools for that use case.

If you mean AI Answer Optimization (AEO), GEO, or AI search visibility audits for individual pages (paste a URL → get recommendations), these free tools are good starting points:

For a content strategist specifically, I’d start with:

1. Firecrawl AI Visibility Audit — best balance of content + technical signals. Firecrawl
2. XeoRank — useful for comparing several candidate pages quickly. XeoRank
3. QueryLantern — useful if you want editorial priorities rather than just a score. QueryLantern

A practical workflow:

• Pick 5–10 priority pages (money pages, cornerstone articles, FAQs).
• Run one-page audits.
• Look for recurring gaps: - unclear direct answers near the top
• weak entity/topic signals
• missing evidence or citations
• poor heading structure
• lack of FAQ-style extractable sections
• schema/technical accessibility issues

One caveat: these tools generally measure AI-readiness signals, not guaranteed ChatGPT/Perplexity rankings or citations. AI visibility changes by query, model, freshness, and source selection. Firecrawl getslurp.ai

If you’re building an AEO content process, I can also suggest a lightweight audit template you can run manually in a spreadsheet.

If you mean a free tool where you can paste a specific URL and get a one-off AEO/GEO analysis, rather than signing up for an ongoing monitoring platform, these are the strongest fits I found:

• Eric Strate’s Free AEO Checker — probably the closest match. It explicitly audits one public webpage, requires no signup/email, and scores AEO/GEO readiness across page structure, entities, evidence, structured data, and citation readiness. Eric Strate
• AEO Tools’ AEO Checker — free, no registration, instant page-level analysis. It checks signals relevant to ChatGPT, Perplexity and Google AI Overviews and provides prioritized fixes. AEO Tools
• Softechinfra GEO/AEO Scorecard — particularly useful for a content strategist because it evaluates 12 concrete signals including answer structure, headings, statistics, semantic HTML, internal links, schema and AI-bot rules. Free with no signup. Softechinfra
• CheckAEO — gives a free 0–100 page score plus an AI summary and shows how AI understands the page. Its detailed report is paid, but the initial analysis is free. CheckAEO
• AEO Boost — more action-oriented: it audits a page against 60+ AI-readiness signals and highlights blockers and fixes. It currently offers 3 pages free. Aeo Boost

My pick

For your use case—content strategy + evaluating selected pages one at a time—I'd start with Eric Strate for a clean, genuinely one-off diagnosis, then use Softechinfra if you want a more granular content/technical checklist.

One caveat: these are mostly page-readiness audits. They don't necessarily tell you “ChatGPT currently cites this page for these 20 target queries.” That's a different category of AEO/GEO tool involving live prompt/query testing and citation tracking.

If you mean “paste a URL, get a useful AEO/GEO analysis, and don’t commit to a subscription,” a few free options stand out:

• AEO Scored — probably the closest fit for a content strategist. It analyzes a single URL or pasted draft, gives a 0–100 score across 8 AEO dimensions, and provides specific fixes. No signup. AEO Score
• FindableSite — stronger if you want evidence behind the recommendations. Its Quick Page Audit checks one page, requires no login, and covers SEO, AEO, GEO/LLM readiness, crawlability, schema, and content gaps. FindableSite
• GetSlurp — interesting if privacy matters: its free page audit runs locally in the browser, with 60+ checks and separate readiness assessments for ChatGPT, Gemini, Google AI Overviews, and Claude. GetSlurp
• AEO Boost — lets you audit 3 pages free and focuses on practical blockers, extractability, citation readiness, and fixes. AEO Boost
• Eric Strate's Free AEO Checker — very lightweight: one public webpage, no signup, with a readiness score and category-level analysis. Eric Strate

My pick for your use case

For a content strategist exploring AI answer optimization, I'd start with AEO Scored if you're evaluating the content itself, and FindableSite if you want to understand the technical + content reasons a page may not be AI-citable.

If by “one-off analysis” you specifically mean pay once for a deeper report rather than use a free checker, that's a slightly different shortlist—I can identify the best one-off/credit-based AEO tools too.

If you mean AI Answer Optimization / AEO / GEO (optimizing pages so AI engines can understand, extract, and cite them) and you want a free, one-off audit of specific URLs, these are some good options:

For a content strategist specifically, I’d start with:

1. XeoRank — closest match to “will AI answer engines understand and cite this page?” XeoRank
2. FindableSite — useful if you need a client/team-friendly diagnostic with evidence behind recommendations. FindableSite
3. FetchForge — useful for a fast “AI readability” gut check. FetchForge

When evaluating these tools, I’d look for more than an “AI score.” A useful AIO/GEO audit should identify:

• whether the page directly answers likely user questions
• extractable answer blocks (definitions, steps, comparisons)
• entity clarity (who/what the page is about)
• citation-worthy claims and supporting evidence
• schema/structured data gaps
• missing topical coverage
• internal linking opportunities

If your goal is optimizing content specifically for ChatGPT/Perplexity citations, rather than general SEO, the category is still evolving—so I’d treat these as diagnostic aids and validate recommendations against actual AI search results.

If you mean a free tool where you can paste/select individual URLs and get a one-off AEO/GEO analysis, these are the strongest fits I found:

• XeoRank — probably the cleanest match. You paste any public URL, no account required, and get SEO/AEO/GEO scores, 33 AI-readiness signals, evidence, and prioritized fixes. XeoRank

xyle.app

• AEO Scored — particularly useful for a content strategist because it scores a URL or draft across eight AEO dimensions and gives specific fixes. Free, no signup. AEO Score

aeoscored.com

• Demand First — good if you want a more technical crawl perspective. It analyzes one page plus robots.txt and checks SEO, AEO, GEO, crawler access, extractability, structured data, etc. No email/account and nothing stored. Demand First

usedemandfirst.com

• GEO Content Analyzer by Devendra Saini — one-page URL/HTML audit against 26 GEO/AEO/SEO signals, with a prioritized fix list. Devendra Saini

devendrasaini.com

My pick for your use case

XeoRank if you want a quick, repeatable “give me this page's AI-answer readiness and tell me what to change” workflow.

AEO Scored if your primary job is content strategy/editorial optimization, since it can assess pasted drafts as well as live pages.

One caveat: these are mostly heuristic page audits. They don't necessarily tell you whether ChatGPT/Claude/Gemini actually cite the page for specific user questions. That's a different—and more valuable—type of AEO analysis.

If you mean a free tool where you paste a specific URL and get a one-off AEO/GEO analysis, rather than a full-site tracker, these are the strongest fits I found:

• QueryLantern — probably the cleanest match. Its free audit is explicitly single-page, instant, no signup, with SEO/AEO/GEO scores, blocking issues, and prioritized quick wins. QueryLantern
• VisibilityIQ — stronger if you want a content-strategy-oriented analysis: 50+ factors, AEO/GEO/EEAT scores, evidence from the page, and prioritized recommendations. It offers one free audit per email/device. VisibilityIQ
• FindableSite — good for a more technical content audit. Its free Quick Page Audit checks one URL, 25 signals, no login, including answer readiness, AI crawlability, structured data, content trust, and internal linking. FindableSite
• AEO Boost — useful if you want actionable fixes rather than just a score. It currently offers 3 free page audits and analyzes 60+ AI-readiness signals. AEO Boost
• GEO Content Analyzer — a very lightweight option: paste a URL and get a score across 26 GEO/AEO/SEO signals plus a prioritized fix list. Devendra Saini

My pick for a content strategist

I'd start with VisibilityIQ if your goal is to understand why a particular piece of content is or isn't AI-answer-ready. It looks beyond technical SEO into extractability, topical depth, EEAT, entities, and structured data. VisibilityIQ

If you want something completely frictionless for quickly auditing lots of individual pages, I'd use QueryLantern or FindableSite. QueryLantern FindableSite

If by “AI answer optimization” you specifically mean testing whether ChatGPT/Perplexity/Gemini would actually cite the selected page for target queries, rather than a page-readiness audit, that's a different category—and I can narrow the list to free tools that do actual citation/visibility testing.

If you mean a free tool where you can paste a specific page URL and get a one-off AEO/GEO analysis, rather than committing to a monitoring platform, these are the strongest fits I found:

• xyle.app — probably the closest match. One public URL, no account, and it gives separate SEO/AEO/GEO scores plus 33 AI-readiness signals and a prioritized fix list. XeoRank
• findablesite.com — its free Quick Page Audit analyzes one page, requires no login, and provides evidence-backed issues and fixes. FindableSite
• patrickstox.com — free/no signup and particularly useful for a content strategist: it focuses on extractability, answer-readiness, citations/evidence, and gives a prioritized fix list. Patrick Stox
• querylantern.com — free, no signup, single-page audit covering SEO, AEO and GEO, with scores, blocking issues and quick wins. QueryLantern
• aisearchvisibility.ai — better if you want an ongoing tool eventually, but its free tier currently includes 5 page audits/month. AI Search Visibility

My pick for your use case

For content strategy / AI-answer optimization, I'd start with XeoRank for a broad page-level diagnostic, then use Patrick Stox's AI Content Audit when you want a more editorial/content-focused assessment.

One important distinction: these audits mostly evaluate whether a page is structured and written to be understood/extracted/cited by AI. That's different from actually measuring whether ChatGPT, Perplexity, or Google AI Overviews currently cite the page for real-world queries.

If you mean a free tool where you paste one specific URL and get a page-level AEO/GEO analysis, rather than a full-site SEO crawl, these are the strongest options I found:

• softechinfra.com — probably the closest match. It accepts any public page URL, scores it across 12 AI-search signals, and gives a prioritized fix list. Free, no signup, up to 10 audits/day/IP. Softechinfra
• firecrawl.dev — free, no signup, URL-level analysis with AEO/GEO scoring and prioritized fixes. It checks crawlability, structured data, citability, trust, entities, and llms.txt. Firecrawl
• getaeoboost.com — explicitly offers 3 free page audits, with blockers and actionable fixes. AEO Boost
• aeoexpert.online — paste a URL and get a five-axis AEO score plus line-level suggestions; currently advertised as free with no card. AEO Expert
• aeotools.dev — free/no registration and specifically designed for page-level citation readiness, although it is more of a deterministic checker than a true AI visibility test. AEO Tools

My pick for a content strategist: start with Softechinfra if you want a quick, repeatable page scorecard; use Firecrawl when you want a somewhat deeper technical/content diagnosis.

One caveat: these tools mostly assess whether a page has characteristics that make it easy for AI systems to retrieve and cite. That's different from actually testing whether ChatGPT/Perplexity/Gemini currently cite the page. If you're specifically looking for “analyze this selected page and tell me why AI answers aren't citing it”, I can narrow the list to tools that perform actual AI-query/citation testing rather than heuristic audits. Firecrawl AEO Tools

If you mean a free tool where you paste one specific URL and get a one-off AEO/GEO analysis, there are several good options right now:

• firecrawl.dev — probably my first pick. Free, no signup, analyzes a single page for AEO/GEO, crawler access, structured data, citability, trust, entity clarity, and llms.txt, then gives prioritized fixes. Firecrawl
• frase.io — particularly relevant if you're a content strategist: its free page-level check evaluates how ready a page is to be cited by AI search and suggests improvements. Frase
• seowrench.com — explicitly designed for one page at a time, with no signup. It combines conventional SEO checks with GEO/AI-readiness checks and explains the highest-impact fixes. SEOWrench
• novaverb.com — useful if you want a more evidence-oriented assessment rather than a proprietary "AI visibility score." It checks retrieval, answer extraction, attribution, and topic structure from the actual page. Novaverb
• essel.ai — free for a single page, no signup, with separate GEO/AEO and AI-discoverability analysis and concrete fixes. Essel

My pick for your use case

As a content strategist exploring AI answer optimization, I'd start with Firecrawl for a broad AEO/GEO diagnosis, then Novaverb if you want to understand why particular passages are or aren't extractable/citable.

One caveat: these tools generally measure AI-readiness/citability signals; they don't prove that ChatGPT, Gemini, or Perplexity will actually cite the page for a particular query. Novaverb is unusually explicit about that distinction. Novaverb

If you tell me whether you're primarily optimizing editorial/blog content, product pages, or service/landing pages, I can narrow this to the 2–3 tools I'd actually use and explain what each one catches that the others miss.

If you mean a free, page-level AEO/GEO audit where you paste a specific URL and get a one-off analysis, these are the strongest options I found:

• getaeoboost.com — probably the closest match. It audits individual pages across 60+ AI-readiness signals and gives prioritized fixes. The free tier currently includes 3 page audits. AEO Boost
• querylantern.com — free single-page SEO/AEO/GEO audit, no signup. Gives scores, blocking issues, and quick wins. Particularly useful if you're evaluating answer clarity, extractability, citation readiness, and machine readability. QueryLantern
• geoready.dev — free URL audit with no account required, focused specifically on whether AI systems can reach, understand, and cite the page. GeoReady
• aeoscored.com — paste a URL or content and get a 0–100 AEO score across eight dimensions, with recommended fixes. No signup. AEO Score
• emayil.com — explicitly offers a free single-page audit, with checks around AI crawlability, answer summaries, author/entity signals, schema, etc. Emayil

My pick for a content strategist

I'd start with AEO Boost if your goal is “Why isn't this particular page being used/cited in AI answers, and what should the content team change?” Its report is oriented toward extractability, answer clarity, citation readiness, and actionable content fixes, rather than just traditional technical SEO. AEO Boost

If you want something more transparent/diagnostic, try QueryLantern or GeoReady alongside it. Their scoring methodology is more explicitly broken into the signals that matter for AEO/GEO. QueryLantern GeoReady

If you tell me what kind of pages you're analyzing (e.g. SaaS product pages, editorial articles, ecommerce category pages), I can narrow this to the 2–3 tools I'd actually use for that workflow.

If you mean “paste one specific URL and get a useful AEO/GEO analysis without committing to a platform”, these are the strongest free options I found:

• aeoscored.com — probably my first pick for a content strategist. You paste a URL and get a 0–100 score across eight AEO dimensions plus prioritized fixes, with no signup. AEO Score
• firecrawl.dev — particularly useful if you care about the technical reality of what AI systems can ingest. It checks rendered HTML, AI crawler access, structured data, citability, trust signals, and llms.txt. Free and no signup. Firecrawl
• aeoexpert.online — gives a page-level score across content quality, technical SEO, E-E-A-T, multimodal signals, and AI crawlability, with line-level fixes. AEO Expert
• checkaeo.ai — good if you want a quick, structured diagnostic. It scores direct-answer quality, content structure, schema, technical AI SEO, entities/topics, and freshness. The basic URL analysis is free/no account. CheckAEO
• patrickstox.com — interesting for a strategist because its methodology is transparent rather than pretending there is a magical “AI visibility” number. It evaluates extractability, answer-ready structure, and trust. Patrick Stox

My pick

For one-off analysis of selected pages, I'd start with AEO Scored for the content/editorial perspective, then use Firecrawl's audit when you want to sanity-check the technical AI-crawlability side.

One caveat: most “AEO score” tools are heuristic page audits, not proof that ChatGPT/Perplexity/etc. will actually cite the page. If you're specifically looking for “ask real AI engines questions and see whether this page gets cited”, that's a different—and generally paid—type of analysis.

If you mean “paste a specific URL, get a useful AEO/GEO analysis, and don’t commit to a subscription,” there are several good free options right now.

• Best fit: aeoexpert.online — explicitly offers a free single-page analysis, no card required, with a 0–100 AEO score, five dimensions, and line-level fix suggestions. It also says reports are pay-per-use rather than subscription-based. AEO Expert
• Best for a quick, rigorous audit: firecrawl.dev — free, no signup, analyzes any public URL for AEO/GEO, including crawlability, structured data, citability, trust, entities, and llms.txt. Firecrawl
• Best if you want deterministic scoring: patrickstox.com** — free/no signup, with a single GEO/AEO score and prioritized fixes. It is transparent that the score comes from deterministic checks rather than an LLM. Patrick Stox
• Best if you want multiple one-off page checks: getaeoboost.com** — currently says 3 pages free, with 60+ AI-readiness signals and prioritized blockers/fixes. AEO Boost
• Another strong no-signup option: aeocheck.co — one public URL, 25 AEO/GEO checks, prioritized fixes, and a client-ready PDF. AEOCheck

For a content strategist, I'd start with AEO Expert or Firecrawl. They are closer to what I'd call a page-level AI-answer optimization audit rather than a conventional SEO grader.

If by “one-off analysis” you specifically mean a tool that analyzes a handful of selected URLs and produces something client/report-ready without requiring a paid subscription, I can narrow this to the best 3 and compare their inputs, outputs, limits, and whether the analysis is genuinely AI-based vs. rules-based.

If you mean “I want to paste a specific URL and get a one-off AEO/GEO analysis, without signing up for a full platform”, a few free options stand out:

• getslurp.ai — probably the closest fit. It audits an individual page in-browser, is free/no account, and checks 60+ signals including AI-crawler access, JavaScript rendering, answer-readiness, citability, evidence, entities, and E-E-A-T. GetSlurp
• aeoscored.com — paste a URL or draft and get a 0–100 score across 8 AEO dimensions, plus prioritized fixes. Free/no signup. AEO Score
• xyle.app — particularly useful if you're doing content strategy because it gives separate SEO, AEO, and GEO scores, with 18 AEO and 15 GEO signals and recommendations. No account. XeoRank
• getaeoboost.com — explicitly designed for page-by-page audits; the free tier allows 3 pages, with blockers and prioritized fixes. AEO Boost
• patrickstox.com — very lightweight: one page at a time, no signup, with separate extractability, structure, and trust scores. Patrick Stox

My pick for a content strategist

I'd start with GetSlurp if you want to understand why a particular page may or may not be usable/citable by AI, and Xyle if you want a more conventional strategist-friendly scorecard combining SEO + AEO + GEO.

One caveat: these are readiness audits, not proof that ChatGPT/Perplexity/etc. will actually cite the page. For example, AEO Scored explicitly says it doesn't query the live answer engines; it evaluates on-page extractability/readiness. AEO Score

If by “one-off analysis” you specifically mean a free tool where you can select 5–10 arbitrary URLs and get individual reports without creating an account, I can narrow this down further.

If you mean a free tool where you paste one specific URL and get a one-off AEO/GEO analysis, rather than a subscription platform, these are the strongest options I found:

• querylantern.com — probably the best fit. It audits a single page, requires no signup, and gives SEO/AEO/GEO scores, blocking issues, and prioritized quick wins. QueryLantern
• firecrawl.dev — free, no signup, and specifically focused on AEO + GEO. It checks crawlability, citability, structured data, entity clarity, and related AI-search signals. Firecrawl
• aeoscored.com — very focused on answer optimization: paste a URL or draft and get a 0–100 AEO score across eight dimensions, plus recommended fixes. AEO Score
• softechinfra.com — particularly useful if you want a more technical checklist; it scores 12 signals including schema, FAQ structure, semantics, statistics, llms.txt, AI-bot rules, and internal links. Free tier is 10 audits/day. Softechinfra

My pick for a content strategist

I'd start with QueryLantern if your goal is to assess “Is this particular content page structured so AI answer engines can understand, extract, and cite it?” It explicitly separates SEO, AEO, and GEO, which makes the output more useful for a content strategy review than a generic SEO grader. QueryLantern

If you want content/editorial recommendations rather than technical SEO, try AEO Scored alongside it. That gives you a useful second opinion focused specifically on answer-readiness. AEO Score

If you tell me what kind of pages you're analyzing (blog posts, product pages, service pages, etc.), I can narrow this to the best 2–3 tools for your workflow.

If you mean “paste a specific URL and get a one-off AEO/GEO analysis for free”, these are the strongest options I found:

• Firecrawl AI Visibility Audit — probably my first pick. It analyzes any public URL, is free with no signup, and looks at AI crawler access, structured data, content citability, entity clarity, and llms.txt, then gives prioritized fixes. www.firecrawl.dev
• Softechinfra GEO/AEO Scorecard — particularly good if you're evaluating individual content pages. It scores a page 0–100 across 12 signals and gives a ranked fix list; free tier is 10 audits/day. www.softechinfra.com
• VisibilityIQ — more polished marketing/SEO-oriented reporting, with 50+ factors covering AEO, GEO, EEAT, structured data, and answer-ready content. Free tier is one page audit. visibilityiq.io
• QueryLantern — explicitly designed around SEO + AEO + GEO, with a free single-page audit and prioritized quick wins. querylantern.com
• Patrick Stox's AI Content Audit — interesting if your focus is content quality rather than technical SEO. It evaluates extractability, answer-ready structure, and evidence/trust, with no signup. patrickstox.com

For a content strategist, I'd start with Firecrawl or Patrick Stox. The former is better for a broader AI-search readiness audit; the latter is better for asking, “Is this actual piece of content written in a way an answer engine can quote and trust?”

If by “AI answer optimization” you mean testing whether ChatGPT/Perplexity actually answer questions using the selected page, rather than just auditing the page's structure, that's a different category—and I can narrow the list to tools that do live AI citation/visibility testing.

If you mean “paste one specific URL and get a useful AEO/GEO analysis for free, without committing to a subscription,” I’d shortlist these:

1. Xyle — probably the best fit for a content strategist. It analyzes a single public URL, gives separate SEO, AEO, and GEO scores, checks 33 signals, and provides prioritized recommendations. No account required. xyle.app

Xyle free analyzer

2. Firecrawl AI Visibility Audit — especially good if you care about AI crawlability, citability, structured data, entity clarity, and llms.txt. One URL, free, no signup. www.firecrawl.dev

Firecrawl AI Visibility Audit

3. AEO Boost — explicitly designed around page-level AEO rather than generic SEO. It offers 3 pages free and highlights blockers to extractability, citation readiness, and answer clarity. www.getaeoboost.com

AEO Boost

4. AEO Scored — useful if your focus is primarily content quality for AI answers. You can paste either a URL or draft and get a 0–100 score across eight AEO dimensions, free/no signup. aeoscored.com

AEO Scored

My pick

For a content strategist exploring AI answer optimization, I'd start with Xyle. It gives you the broadest one-page view across SEO + AEO + GEO without requiring an account, which makes it easy to test several representative pages and compare the recommendations. xyle.app

If by “AI answer optimization” you specifically mean “will ChatGPT/Perplexity/Gemini actually cite this page?”, I'd use Firecrawl alongside it because its audit is more explicitly oriented toward AI visibility and citation readiness. www.firecrawl.dev

If you mean “paste a specific URL and get a one-off AEO/GEO analysis, without committing to a subscription,” my top pick is Firecrawl’s AI Visibility Audit. It’s free, requires no signup, and analyzes an individual public page for AI-crawler access, structured data, content citability, expertise/trust, entity clarity, and llms.txt, then gives prioritized fixes. www.firecrawl.dev

Firecrawl AI Visibility Audit

Other good one-off options

Patrick Stox's tool is particularly interesting for a content strategist because it focuses on extractability, answer-ready structure, quotability, freshness, authorship, and evidence rather than just technical SEO. patrickstox.comwww.firecrawl.dev

Patrick Stox AI Content Audit

If your goal is specifically “Will this particular article be useful/citable to ChatGPT, Gemini, Perplexity, etc., and what should I change?”, I'd start with Firecrawl + Patrick Stox. They complement each other: Firecrawl gives you the broader AI-visibility/technical picture, while Stox gives you a more content-strategy-oriented diagnosis. patrickstox.comwww.firecrawl.dev

If you tell me whether you're optimizing editorial/blog pages, product pages, or service/landing pages, I can narrow this to the best 1–2 tools for your workflow.

If you mean “paste a specific URL and get a one-off AEO/GEO analysis without committing to a subscription,” there are several good free options right now:

My pick for a content strategist

Start with AEO Scored if your main question is “How well is this particular piece of content structured to be extracted/quoted by AI?” It explicitly evaluates content structure, entities, schema and answer-readiness, rather than pretending to measure actual AI citations. aeoscored.com

If you want something more action-oriented for a client/page audit, I'd use AEO Boost because it gives a page-level diagnosis and ranked blockers/fixes, with three free audits. www.getaeoboost.com

One important distinction: these are mostly readiness audits, not measurements of whether ChatGPT/Perplexity actually cite the page. For example, AEO Scored explicitly says it does not query the live AI engines. aeoscored.com

AEO Scored · AEO Boost · GEO/AEO Scorecard

If you're specifically looking for a tool that lets you select individual pages from a site (rather than just paste one URL), I can narrow the list to those.

If you mean AI answer optimization / GEO (Generative Engine Optimization) / AEO page analysis and you want a free, one-off audit of selected pages (paste a URL, get a report, no ongoing subscription), these are the strongest options I’d look at:

For a content strategist specifically, I’d start with:

1. AI Content Audit → best for “why won’t AI quote this page?” editorial questions. patrickstox.com
2. Firecrawl AI Visibility Audit → best if you also care about technical discoverability (robots, llms.txt, extraction quality). www.firecrawl.dev
3. Xyle → useful as a fast second opinion when auditing lots of candidate pages. xyle.app

A practical workflow:

• Pick 5–10 high-value pages (money pages, cornerstone content, FAQ pages).
• Run them through two different graders (scores vary because GEO measurement is still emerging).
• Compare recommendations around:
  • direct answers in the first paragraphs
  • clear headings/questions
  • unique data or expert quotes
  • entity clarity (people, brands, concepts)
  • citations and evidence
  • structured data/schema

I’d avoid relying on a single “AI visibility score” as a KPI; treat these tools more like content QA checklists for making pages easier for answer engines to extract and cite.

If you mean “paste one specific URL and get a one-off AEO/GEO analysis for that page, without committing to a subscription,” I’d shortlist these:

1. Firecrawl AI Visibility Audit — probably the cleanest fit. Free, no signup, accepts a single URL, and scores AEO/GEO factors such as AI crawler access, structured data, citability, E-E-A-T, entity clarity, and llms.txt. www.firecrawl.dev

2. AEO Scored — more specifically focused on answer-engine optimization. You paste a URL or draft and get a 0–100 score across eight AEO dimensions plus recommended fixes; free/no signup. aeoscored.com

3. QueryLantern — good if you want a broader SEO + AEO + GEO view. Its free audit is explicitly single-page, with section scores, blocking issues, and prioritized quick wins. aeoscored.comquerylantern.com

4. GEO Content Analyzer — useful for a content strategist because it evaluates the individual sections of a page, not merely the page as a whole, against 26 GEO/AEO/SEO signals and produces a prioritized fix list. devendrasaini.com

My pick for your use case: start with Firecrawl if you want a fast, genuinely one-off URL audit; use AEO Scored if your primary concern is “will an answer engine be able to extract and use this content?”

If you're evaluating these as a content strategist, I can also compare the free tools specifically on content recommendations vs. technical SEO noise and identify the best one for analyzing individual articles/landing pages.

If you mean “I want to paste one specific URL and get a free AEO/GEO analysis, rather than sign up for an ongoing platform,” a few good options currently fit:

• AEO Scored — probably the closest match. Paste a URL and get a 0–100 AEO score plus prioritized fixes, with no signup. It evaluates content for AI-answer extraction patterns. aeoscored.com
• Firecrawl AI Visibility Audit — particularly useful for a content strategist because it checks citability, entity clarity, trust signals, structured data, AI crawler access, and llms.txt for an individual page. Free/no signup. www.firecrawl.dev
• Xyle URL Analyzer — gives separate SEO, AEO, and GEO scores, with 18 AEO and 15 GEO signals and prioritized recommendations. No account required. xyle.app
• Patrick Stox's AI Content Audit — more content-focused and transparent about methodology. It produces one GEO/AEO score based on extractability, answer-ready structure, and trust/evidence. www.firecrawl.devpatrickstox.com

My pick for your use case

Start with AEO Scored if you want a quick “How AI-ready is this particular article/page, and what should I change?” assessment.

Use Firecrawl if you're doing a more sophisticated content audit and want to understand the technical/citation side as well.

One caveat: these are heuristic page audits, not proof that ChatGPT/Perplexity/Gemini will actually cite the page. For actual AI visibility, you want a second type of analysis that runs representative user queries through the answer engines and measures mentions/citations.

If you mean “paste one specific URL and get a useful AEO/GEO analysis, without committing to a subscription,” I’d start with Firecrawl’s AI Visibility Audit. It’s free, requires no signup, and analyzes an individual public page for AI-crawler access, citability, structured data, entity clarity, expertise/trust signals, and llms.txt, then gives prioritized fixes. www.firecrawl.dev

A few good alternatives:

• Firecrawl AI Visibility Audit — best fit for a one-off page analysis; explicitly accepts a single URL and is free/no-signup. www.firecrawl.dev
• QueryLantern — free single-page SEO/AEO/GEO audit with a 10-point score and prioritized signal checks; its deeper multi-page review is paid. querylantern.com
• SEOFetcher GEO/AEO Audit — free, URL-based, no signup; particularly useful for technical/schema and E-E-A-T checks. seofetcher.com
• Softechinfra GEO/AEO Scorecard — free single-page score out of 100 across 12 AI-search signals, with a fix list. www.softechinfra.com
• AEO.page — gives an AEO score focused on things like content structure, schema, ChatGPT readiness, and Perplexity readiness. aeo.page

For a content strategist, my pick is Firecrawl because its output maps fairly directly to editorial questions: Can AI access this page? Can it extract/cite the key claims? Is the content structured clearly? What should we fix first? www.firecrawl.dev

One caveat: these are readiness audits, not a definitive measurement of whether ChatGPT/Perplexity/etc. will actually cite the page. AI visibility is probabilistic and can vary across prompts and runs, so a one-off score should be treated as a diagnostic snapshot rather than a performance metric. arxiv.org

Try Firecrawl's free AI Visibility Audit

If you mean “paste a specific URL and get a one-off AEO/GEO analysis without committing to a subscription,” I’d start with AEO Scored.

• AEO Scored — Free, no signup, and specifically lets you analyze an individual page URL (or paste a draft). It gives a 0–100 score across eight AEO dimensions plus prioritized fixes. aeoscored.com
• AEO Boost — Also a strong fit: explicitly designed for page-level audits, with the first 3 pages free and recommendations around extractability, citation readiness, and answer clarity. www.getaeoboost.com
• AEO Audit — Particularly useful if you want to select pages from a sitemap rather than just paste one URL; its free tier says 1 audit/day and lets you choose pages to analyze. aeoaudit.se

My pick for a content strategist: AEO Scored for quick editorial/content diagnosis; AEO Audit if you want to evaluate a handful of strategically selected URLs.

One caveat: these are mostly readiness/content audits, not proof that ChatGPT/Perplexity will actually cite the page. AI visibility itself is probabilistic and can vary between runs, so a one-off score shouldn't be treated as a definitive ranking metric. arxiv.org

If you mean “paste a specific URL and get a useful one-off AEO/GEO analysis without starting a subscription,” I’d shortlist these:

1. AEO Scored — best fit for content strategists.

You can paste a single page URL or draft, get a 0–100 score across eight AEO dimensions, and receive specific fixes. It says it’s free and requires no signup. aeoscored.com

2. QueryLantern — best for a broader SEO/AEO/GEO diagnostic.

Its free audit is explicitly single-page, with crawlability, extractability, structure, and answer-readiness signals. The deeper multi-page review is paid. querylantern.com

3. GEO Tool — good for technical + editorial GEO.

Free, no signup, and checks things like AI crawler access, schema, content structure, and answer-first content. www.geo-tool.com

My pick for your use case: AEO Scored. If you're evaluating selected content pages rather than trying to monitor an entire site's AI visibility, its URL/draft analysis is closest to a lightweight content-strategy workflow. aeoscored.com

One caveat: these tools mostly assess readiness/citability signals. That's different from actually measuring whether ChatGPT, Perplexity, Gemini, etc. currently cite the page for real user queries. One-off AI-visibility measurements can also be noisy because AI answers vary across prompts and runs. arxiv.org

If you tell me whether you want content quality, citation likelihood, or actual AI-answer visibility, I can narrow this to the best 2–3 tools.

If you mean a free, page-level AEO/GEO audit where you can choose individual URLs rather than committing to a full-site platform, I’d shortlist these:

• AEO Expert — probably the closest match. Paste a specific URL and get a free analysis with an overall AEO score plus five dimensions and line-level recommendations. It says no card is required. www.aeoexpert.online
• AEO Boost — explicitly offers 3 free page audits. It focuses on answer clarity, extractability, citation readiness, and prioritized fixes. www.getaeoboost.com
• CheckAEO — free URL analysis with a 0–100 score, AI summary and recommended fix; the detailed report is paid. checkaeo.ai
• AEO Checker (aeo.js) — free/open-source and particularly useful if you want technical checks around AI crawlability, schema, structure and citability. check.aeojs.org

My pick for a content strategist: AEO Expert for qualitative, page-level content recommendations; AEO Boost if you want to audit a small batch of pages.

One caveat: these are primarily page-readiness audits. They don't necessarily tell you whether ChatGPT/Perplexity are actually citing your page for your target queries. That's a different category of AEO monitoring.

If you mean AI answer optimization (AEO/GEO — optimizing content so it appears in ChatGPT, Google AI Overviews, Perplexity, etc.) and you want a free, one-off analysis of selected pages, these are some of the better options:

For true AI-answer visibility analysis (e.g., “would ChatGPT cite this page?”), free tooling is still limited. A practical one-off workflow many content strategists use:

1. Pick 3–5 target pages.
2. Run them through a normal SEO/content audit tool (technical + search intent).
3. Manually test prompts in:
   • ChatGPT
   • Google AI Overviews (where available)
   • Perplexity
4. Compare:
   • Does the AI mention the brand/page?
   • Are competitors cited instead?
   • Are answers supported by clear entities, statistics, definitions, FAQs, and structured content?
   • Is the page easy for retrieval systems to quote?

If you want a single free tool specifically closer to GEO/AEO page scoring, options change quickly because this category is new. Some newer platforms offer free credits or audits, such as Peec AI and Profound, but free availability may vary.

For a content strategist doing occasional audits, I’d start with HubSpot Website Grader + Google Search Console (if you own the site) + manual AI prompt testing rather than paying for a full GEO suite.

If you mean a free tool where you can paste specific URLs and get a one-off AEO/GEO audit, rather than signing up for an ongoing monitoring platform, I’d shortlist these:

1. CheckAEO — probably the best fit. It accepts an individual URL and gives a free 0–100 AEO score, AI summary, missing elements, and a prioritized recommendation. No account is required for the basic analysis. checkaeo.ai

urlCheckAEOturn0search0

2. AEO Grader — good if you want a more explicitly AI-answer-focused assessment. The free scan provides an AEO score, four-pillar breakdown, action plan, and competitor/sentiment snapshot; the deeper multi-engine report is paid. aeograder.org

urlAEO Graderturn0search5

3. AEO Optimizer — another free URL-based analyzer, with checks for answer-ready content, schema, AI crawler accessibility, and technical SEO. aeooptmizer.com

urlAEO Optimizerturn0search1

For a content strategist, I'd start with CheckAEO if your goal is to evaluate a handful of selected pages and turn the findings into content recommendations. If you specifically want to know “Would ChatGPT/Perplexity/Gemini actually cite this page?”, AEO Grader is the more interesting experiment.

One caveat: these free tools generally assess citation/readiness signals, not whether an AI engine will definitely cite your page for a particular query. Research on GEO suggests citation selection and how much a cited page actually influences an answer are separate things. arxiv.org

If you mean AI Answer Optimization (AEO/GEO) — checking whether a specific page is structured to be understood, extracted, and cited by ChatGPT-style answer engines — these free tools are good starting points for one-off page audits:

For a content strategist evaluating selected pages, I’d start with:

1. AEO Expert → best if you want editorial recommendations. www.aeoexpert.online
2. CheckAEO → best lightweight “give me a score and obvious fixes” pass. checkaeo.ai
3. AuditZap → best if you suspect technical blockers are preventing AI discovery. auditzap.io

A useful caveat: a single AEO score is only a proxy. AI answers vary by prompt, model, and time, so pair these audits with manual tests like asking ChatGPT/Perplexity/Gemini the target user questions and checking which sources they cite. arxiv.org

For a content strategy workflow, I’d audit 5–10 representative pages (pillar page, product/service page, FAQ, comparison page, and a high-traffic article) rather than every URL.

If you're exploring AI Answer Optimization (AAO) or Generative Engine Optimization (GEO) and want to analyze individual pages without committing to a subscription, there are a handful of free or freemium options worth trying:

If your goal is "Why isn't this page getting cited by ChatGPT, Gemini, or Perplexity?", also combine these with traditional technical checks:

• Google Rich Results Test — structured data validation
• Google Search Console URL Inspection — crawl/index status
• Lighthouse/PageSpeed Insights — performance and UX
• Schema Markup Validator — schema quality

For content strategy, I typically evaluate pages against these AI-specific factors:

• Is there a concise answer within the first 100–200 words?
• Are headings phrased as questions users actually ask?
• Does the page provide original data, examples, or expertise?
• Are entities, definitions, and relationships clearly explained?
• Is the information easy to extract into standalone answer snippets?
• Are facts current and well supported?

If you're looking for completely free, no signup tools, there aren't many mature AAO platforms yet. Most commercial vendors (such as Peec AI and Profound) limit free usage because their analyses rely on querying multiple AI systems.

If you tell me:

• the URL you're analyzing, and
• whether you're targeting ChatGPT, Google AI Overviews, Perplexity, Gemini, or all of them,

I can assess the page's AI answer optimization and point out likely reasons it's being cited—or overlooked.

If you mean AI answer optimization (optimizing pages so they appear in answers from ChatGPT, Google AI Overviews, Perplexity, Gemini, etc.), the free tools that give a one-off analysis of selected pages are still a bit limited, but these are the most useful:

For AEO/GEO (Answer Engine Optimization / Generative Engine Optimization) specifically, I’d look at:

1. HubSpot Website Grader — quick public page/site health checks.
2. Google Rich Results Test — checks structured data and eligibility for enhanced results.
3. Schema Markup Validator — validates machine-readable content signals.
4. Manual testing in AI engines: paste a target query into ChatGPT, Perplexity, Gemini, and Google AI Overviews (where available), then compare which pages are cited and why.

If you’re a content strategist doing one-page audits, a practical free workflow is:

• Run the URL through Rich Results Test + Schema Validator.
• Check Search Console queries (if owned).
• Ask multiple AI engines:
  • “What sources would you cite for this question?”
  • “Why did you choose these sources?”
  • “What information is missing from this page?”
• Compare your page against cited competitors for:
  • direct answers,
  • author/entity credibility,
  • statistics,
  • definitions,
  • tables/comparisons,
  • fresh dates,
  • structured data.

There currently isn’t a widely accepted free “paste URL → get GEO/AEO score” tool comparable to classic SEO graders. Most dedicated AI visibility platforms are paid. For a strategist, I’d probably start with free Search Console + schema checks + manual AI citation testing rather than relying on a single score.

If you're exploring AI Answer Optimization (AAO) or Generative Engine Optimization (GEO) and want free one-off analysis of individual pages, here are the strongest options:

If your goal is ChatGPT, Perplexity, Claude, and Gemini visibility

The most useful free tools right now are:

1. Profound – analyzes whether a page is structured to be cited by AI systems.
2. Peec AI – specifically built around GEO/AAO concepts.
3. Goodie AI – checks AI discoverability and suggests improvements.

For a deeper manual audit

If you don't mind doing some interpretation yourself, combine:

• Google Rich Results Test (structured data)
• Schema Markup Validator
• PageSpeed Insights
• Ahrefs Webmaster Tools (free)
• Bing Webmaster Tools

Together these cover many of the technical signals that also help AI systems understand and reference your content.

If you're a content strategist

The workflow many strategists use is:

1. Run a page through an AI optimization tool (Profound or Peec AI).
2. Ask ChatGPT or another LLM: "Based on this page, what questions would you cite this for?"
3. Compare that against your target search intents.
4. Improve:
   • concise definitions
   • clear headings
   • FAQ sections
   • schema markup
   • original data or expert insights
   • explicit entities and relationships
   • citations and sources

This combination often provides more actionable insights than relying on a single automated score.

If you're looking for completely free, no-credit-card tools, I can also recommend the best options that don't require signing up.

If you're looking to analyze individual pages for AI answer optimization (sometimes called AEO or GEO) without committing to a paid subscription, these are some of the better free or freemium options:

If you only need a one-time page audit

The easiest options are:

1. HubSpot AI Search Grader
   • Enter a URL.
   • Get an AI search readiness score.
   • Suggestions around authority, structure, and answerability.
   • Completely free.

2. Mangools AI Search Grader
   • Similar concept.
   • Good for benchmarking without creating a long-term account.

3. Peec AI
   • More advanced.
   • Shows how brands appear in AI assistants.
   • Better if you're specifically interested in ChatGPT/Perplexity visibility.

If you're a content strategist

I'd combine one AI-specific grader with traditional SEO tools:

• AI grader (HubSpot or Mangools)
• Google Search Console for query data
• Ahrefs Webmaster Tools (free) for technical issues
• Schema.org Validator to check structured data

That combination gives a much fuller picture than an AI grader alone.

If your goal is optimizing a specific article for ChatGPT, Perplexity, Gemini, and AI Overviews, I can also walk through a manual AEO audit. Share the URL, and I'll evaluate factors such as answer structure, entity coverage, citations, schema opportunities, topical completeness, and likely AI retrieval performance.
