Answer Engine Optimization (AEO)
AEO is how you get your site cited by AI assistants — ChatGPT, Perplexity, Gemini, and Google AI Overviews — instead of just ranking a link nobody clicks. It's the same job people call GEO(Generative Engine Optimization). The hard part isn't knowing it matters; it's knowing exactly what on your site is keeping the AIs from seeing and trusting you. That's what we audit.
AEO vs GEO vs SEO
The acronyms blur together, so here's the practical version:
| Term | Optimizes for | The win |
|---|---|---|
| SEO | Ranking in a list of links | A blue link on page one |
| AEO | Answer features (AI Overviews, snippets, Perplexity) | Being the cited answer |
| GEO | Generative LLM responses (ChatGPT, Claude, Gemini) | Getting recommended inside the answer |
AEO and GEO overlap so much that most people use them interchangeably. We treat them as one job: make your site visible, readable, and trustworthy to every major AI assistant — and tell you what to fix when it isn't.
The three things AEO actually requires
You can rank #1 on Google and still be invisible to ChatGPT — because a different crawler with different rules never saw your content. AEO closes that gap. Three things have to be true:
- Access.The AI crawlers (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended) must not be blocked in your robots.txt — or silently at the CDN. Cloudflare's Bot Fight Mode is the most common reason a site is accidentally invisible to AI.
- Readability.Most AI crawlers don't run JavaScript. If your content renders client-side, they fetch an empty shell. Server-render or static-generate the content you want cited.
- Trust & structure. Clear headings, answer-shaped content, JSON-LD schema, and a recognizable entity make it easy for an AI to extract and cite you with confidence.
Most AEO tools tell you where you stand. We tell you what to fix.
The crowded part of this market is monitoring — dashboards that show you whether you were mentioned, but leave the fixing entirely to you. Our audit runs 60+ checks against your live site, fetched as each AI bot, and hands back paste-ready fixes (robots.txt, schema, render fixes) with a per-agent severity tag for ChatGPT, Claude, Gemini, Perplexity, Doubao, and Grok — so you fix what hurts you most, where it matters most. Free, no signup, in under 30 seconds.

FAQ
What is AEO (Answer Engine Optimization)?
AEO is the practice of structuring your website so answer engines — ChatGPT, Perplexity, Gemini, Google AI Overviews, Copilot — can read it, trust it, and cite it in their answers. Where classic SEO optimizes to rank a blue link, AEO optimizes to BE the answer: the source the AI quotes or recommends when someone asks a question in your space.
AEO vs GEO vs SEO — what's the difference?
SEO optimizes for ranking in a list of links (Google's ten blue links). AEO (Answer Engine Optimization) optimizes for answer features — being cited in AI Overviews, Perplexity answers, and featured snippets. GEO (Generative Engine Optimization) is the closely related term for getting surfaced inside generative LLM responses (ChatGPT, Claude, Gemini). In practice AEO and GEO overlap heavily and people use them interchangeably; we treat them as one job: get your site visible and cited across AI assistants.
How do I show up in ChatGPT, Perplexity, and Gemini?
Three things have to be true. (1) Access: the AI crawlers (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended) must not be blocked in robots.txt or silently at your CDN. (2) Readability: your content must be in the raw HTML — most AI crawlers don't run JavaScript, so client-rendered content is invisible to them. (3) Trust signals: clear structure, schema (JSON-LD), an entity Google/AI can identify, and answer-shaped content. Our audit checks all three and tells you which are failing.
Is AEO just SEO rebranded?
There's real overlap — good fundamentals (crawlable, fast, well-structured content) help both. But the signals and crawlers differ: AI assistants use llms.txt-style hints, JSON-LD entity extraction, and JavaScript rendering with shorter timeouts, and they're fetched by GPTBot/ClaudeBot/PerplexityBot — not Googlebot. The biggest practical difference: you can rank #1 on Google and still be completely invisible to ChatGPT, because a different crawler with different rules never saw your content. AEO is the work of closing that specific gap.
How do I know if AI assistants can even see my site?
This is the most common silent failure. Cloudflare's Bot Fight Mode and 'Managed robots.txt' frequently block GPTBot, ClaudeBot, and PerplexityBot without the site owner realizing it — so the AIs never read your content even though it's live. Run a free audit: we fetch your site as each AI bot's user-agent, compare what they see to what a browser sees, and flag exactly where you're being blocked or rendered empty.
Does llms.txt help with AEO?
Honestly: it's low-cost but unproven for crawler indexing today. Most AI crawlers don't yet fetch /llms.txt, and independent analyses have found no clear correlation between having one and being cited. Where it does help is agent context — when someone points ChatGPT or Claude directly at your site, a clean llms.txt gives the model a tidy map (Anthropic uses this pattern for its own docs). Treat it as a cheap, optional extra — not the foundation of your AEO. The foundation is crawler access, HTML readability, and structure.
Does AEO replace SEO?
No — it runs alongside it. Google search still drives the majority of web traffic, and AI referral traffic, while growing fast, is still a small share of the total today. The reason to invest now is trajectory and quality: AI Overviews are cutting click-through on informational queries (Pew Research found click rate dropped from 15% to 8% when an AI summary appears), and AI-referred visitors tend to arrive further down the funnel. AEO protects you from zero-click erosion and positions you for where discovery is heading.
