Free AEO Analysis — Is Your Website Ready for AI Search?

ChatGPT, Perplexity, and Google AI Overviews are changing how people find information online. This free AEO and GEO analyzer checks 25+ signals across 5 categories to tell you exactly how visible — and citable — your site is to AI.

Enter any page URL including https://. Analysis takes 10–20 seconds.

AEO vs GEO: What's the Difference?

Traditional SEO gets your pages ranked in Google. But AI search works differently — ChatGPT, Perplexity, Google AI Overviews, and Microsoft Copilot don't rank pages, they synthesise answers and cite the sources they trust most. Two disciplines have emerged to help you show up in those answers.

AEO

Answer Engine Optimization

The technical foundation. Makes your content accessible and clearly structured so AI systems can crawl, parse, and quote it. Correct schema markup, AI-friendly robots.txt rules, clean heading hierarchy, and rich body content that can be extracted as a direct answer.

  • Crawlability & indexability
  • Content quality & freshness
  • Structured data & schema
GEO

Generative Engine Optimization

The trust layer. Generative AI doesn't just need to find your content — it needs to trust it enough to cite it. GEO signals include visible authorship, E-E-A-T indicators, complete entity schemas, and content that demonstrates genuine expertise.

  • Named authorship & credentials
  • Entity & organisation schema
  • E-E-A-T trust signals

Structured data follows the schema.org vocabulary — the standard supported by Google, Bing, and all major AI crawlers. GEO signals align with Google's E-E-A-T quality guidelines for helpful, trustworthy content.

25+ Checks Across 5 Categories

Each category is worth 20 base points. Bonus checks can push your score higher but never penalise you. Total score is out of 100.

Crawlable

AEO

Before AI can quote your content, it needs to find it. This category checks whether your technical setup welcomes AI crawlers like GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and OAI-SearchBot. A misconfigured robots.txt or absent sitemap can silently block AI from ever seeing your content.

  • HTTPS enabled
  • Page is indexable
  • Canonical URL
  • robots.txt
  • AI crawlers allowed
  • sitemap.xml
  • ai.txt (bonus)

Citable

AEO

AI systems look for specific, structured, substantive content that can be extracted and presented as an answer. Thin pages and keyword-stuffed copy get skipped. Pages with clear definitions, numbered lists, tables, FAQs, and 1,000+ words of original insight get cited repeatedly.

  • Meta description
  • Body word count (300+)
  • Content freshness
  • Lists & tables
  • Answer-style structure
  • FAQ content (bonus)
  • 1,000+ words (bonus)

Structured

AEO

AI parses structured signals to understand what a page is about and how much to trust it. JSON-LD schema, proper heading hierarchy, complete Open Graph tags, and descriptive image alt text all help AI form an accurate understanding of your content.

  • Single H1
  • Heading hierarchy
  • JSON-LD schema
  • Open Graph tags
  • Image alt text
  • BreadcrumbList (bonus)
  • Speakable schema (bonus)

Authoritative

AEO + GEO

AI weighs link signals as evidence of credibility. Contextual internal links signal a well-organised site. External links to credible sources signal that you cite evidence. Entity schema — declaring who you are — is one of the strongest signals AI uses to attribute content correctly.

  • Internal body links (3+)
  • External citations (2+)
  • Author / entity schema
  • llms.txt (bonus)
  • Social profile links (bonus)

Verifiable

GEO

This is the pure GEO category, built entirely around E-E-A-T. Generative AI weights content from identifiable, credible sources. Anonymous pages from unknown entities are cited far less often than pages with named authors, linked bios, clear organisational identity, and legal accountability signals.

  • Author name visible
  • Author bio linked
  • About page linked
  • Contact accessible
  • Organisation schema
  • Date visible (bonus)
  • Privacy policy (bonus)

Frequently Asked Questions

Everything you need to know about AEO, GEO, and AI search optimisation.

What is Answer Engine Optimization (AEO)?
Answer Engine Optimization (AEO) is the practice of optimising your website so that AI-powered answer engines — like ChatGPT, Perplexity, Google AI Overviews, and Microsoft Copilot — can find, understand, and cite your content in their responses. Unlike traditional SEO, which focuses on ranking pages in a list of results, AEO focuses on becoming the source that AI systems pull from when they generate answers.
What is Generative Engine Optimization (GEO)?
Generative Engine Optimization (GEO) focuses specifically on trust and authority signals — the factors that determine whether AI systems choose to cite your content over a competitor's. GEO overlaps heavily with Google's E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness) and involves signals like named authorship, complete entity schemas, fresh content, and third-party validation.
How is AEO different from SEO?
Traditional SEO optimises for ranking in a list of blue links. AEO optimises for being cited inside an AI-generated answer. The signals overlap — good SEO helps with AEO — but AEO adds specific requirements around structured data, AI crawler access, content extractability, and entity clarity that standard SEO audits don't cover.
Which AI systems does this tool check for?
Our analyzer checks compatibility with GPTBot (ChatGPT / OpenAI), ClaudeBot (Claude / Anthropic), PerplexityBot (Perplexity), Google-Extended (Google AI Overviews), and OAI-SearchBot. These are the five most widely used AI crawlers currently indexing the web.
What score should I aim for?
We consider 75+ a good score and 90+ excellent. Most sites score between 45–70 on their first analysis, because AEO and GEO are newer disciplines that weren't considered during original site builds. A score below 55 typically indicates significant technical or content gaps that are limiting your AI visibility right now.
What is llms.txt and do I need one?
llms.txt is an emerging standard (similar in concept to robots.txt) that describes your site's structure, key pages, and content permissions specifically for large language models. Early adopters who add a well-structured llms.txt give AI systems a much cleaner map of their content — which typically improves citation rates.
What is ai.txt?
ai.txt is a newer companion standard focused specifically on permissions — declaring how AI systems are allowed to use your content. Think of it as a machine-readable content licence for AI. It's a bonus check in our analyzer because while it's not yet universally required, it signals forward-thinking content governance.
Does this tool analyse my whole website or just one page?
The tool analyses a single page at a time, plus your site-wide files (robots.txt, sitemap.xml, llms.txt, ai.txt). We recommend starting with your homepage, then running checks on your most important service or content pages.
Is this tool free?
Yes, completely free. No account required. Enter any URL and get your full AEO and GEO results instantly. You can also share your results via a unique link.
How often should I re-check my site?
Re-run the analysis after any significant site update — a new template, CMS migration, schema changes, or major content additions. For actively maintained sites, a monthly check is a good habit. Content freshness is a scored signal, so regular updates reflected in your schema will improve your Citable score over time.
