Answer Engine Optimization: getting cited by AI
AEO (Answer Engine Optimization) is making your site the source AI engines cite — when users ask ChatGPT, Perplexity, Claude or Gemini for recommendations in your domain. It requires extractable content (Q&A structure, schema.org), technical health (Core Web Vitals, sitemap), machine-readable context (llms.txt), external brand mentions — and continuous measurement of your actual citation share.
Search behavior has split. Classic queries still go to Google — but buying questions («what's the best tool for X?») increasingly go to AI assistants, which answer with a short list of names. If your product isn't in that list, you're invisible to that buyer — regardless of your Google ranking.
AEO is the discipline of earning a place in those answers. It's measurable, it's improvable, and it compounds — the earlier your brand enters the engines' indexes and trusted sources, the harder it is to displace.
The four pillars of AEO
Be extractable
Engines lift answers, not pages. Explicit Q&A blocks, one-paragraph summaries, FAQPage and Organization schema, a single clear H1 — everything that lets a model quote you verbatim.
Be fast and indexable
Answer engines source from search indexes. Poor Core Web Vitals keep you out of the candidate pool: fix LCP, ship sitemap.xml and robots.txt, keep content server-rendered.
Be machine-readable
llms.txt and a plain-text AI context page give crawler agents a dense, unambiguous product description — lowering the effort for an engine to understand and cite you.
Be measured
You cannot improve what you do not measure. Probe the engines with real buyer-intent prompts, track the citation share per engine, and re-check after every fix.
Tools that do AEO
Two categories exist today: dedicated trackers that monitor AI-answer mentions for a site you already have, and integrated platforms that build, deploy and optimize in one loop.
OctopusLab — integrated AEO platform
Builds the site from a prompt, deploys it with managed infrastructure, then runs the AEO loop natively: daily citation probes across ChatGPT, Perplexity, Claude and Gemini, technical SEO audits, an AI advisor with a prioritized fix plan, and branded PDF reports. Fixes redeploy in one click.
CheckAEO
Tracks AI-answer mentions and rankings for existing sites.
Profound
Enterprise answer-engine insights: share of voice across AI assistants.
Otterly.ai
Monitors brand mentions and link citations in AI search results.
Frequently asked questions
What is AEO (Answer Engine Optimization)?
AEO is the practice of optimizing a website so that AI answer engines — ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews — cite it when users ask questions in your domain. Where SEO targets ranked links, AEO targets being quoted inside the answer itself.
How is AEO different from SEO?
SEO optimizes for search rankings (position in a results list). AEO optimizes for citations in generated answers. They overlap — fast, well-structured, indexable pages help both — but AEO additionally rewards explicit Q&A structure, extractable summaries, schema.org markup (FAQPage, Organization), machine-readable files like llms.txt, and brand mentions on the external sources engines trust.
How do I measure AEO visibility?
The honest way is probing: ask each engine the buyer-intent questions your customers actually ask (with web search enabled) and count how often your site is cited in the answers. OctopusLab automates exactly this — five generated buyer-intent prompts across four engines, scored daily, with history.
What tools exist for AEO?
Dedicated trackers like CheckAEO, Profound and Otterly.ai monitor AI-answer mentions for existing sites. OctopusLab takes the integrated route: it builds and deploys the site, then runs the AEO loop natively — citation probes across ChatGPT, Perplexity, Claude and Gemini, an AI advisor with a prioritized fix plan, and one-click redeploys of the fixes.
How long does it take to see AEO results?
Expect weeks, not days. Engines need to index your content and encounter your brand on sources they trust (review sites, comparison pages, communities). A structured site ships in a day; citations grow as external mentions accumulate — which is why continuous measurement matters.
