SEO vs AEO vs GEO — what they mean and how to win at all three
Search is splitting in three. Google still drives the majority of qualified traffic, but a growing share of buying decisions now start inside an AI assistant.

- SEO gets you into ranked results.
- AEO gets an assistant to name you directly in its answer.
- GEO gets you cited as a source inside AI-generated summaries.

SEO — the foundation
SEO is the practice of earning ranked positions in traditional search engines. It rewards technical health (crawlability, Core Web Vitals, HTTPS), on-page relevance (title, H1, internal linking, content depth), and off-page authority (backlinks, brand mentions, E-E-A-T). If Google can't crawl and understand your site, nothing else in this guide matters — SEO is table stakes for AEO and GEO.
Do this first
- Unique title (50–60 chars) and description (140–160 chars) per page
- One H1, canonical URL, current XML sitemap, clean robots.txt
- Core Web Vitals passing on mobile (LCP, INP, CLS)
- Internal linking from pillar pages to supporting pages
AEO — answer engine optimization
AEO optimizes for the direct, conversational answer an AI assistant gives a user. When someone asks ChatGPT "who are the best divorce attorneys in Boston?", AEO decides whether your brand is named. It rewards answer extractability (short, standalone answers under each heading), FAQ structure, entity clarity, and freshness.
Do this next
- Add an
llms.txtat the root describing your site - Allowlist AI crawlers in robots.txt (GPTBot, Google-Extended, ClaudeBot, PerplexityBot)
- Write short, standalone 40–60 word answers under every H2/H3
- Use FAQPage schema on service and pillar pages
- Publish visible author bios, credentials, and dates (E-E-A-T)
GEO — generative engine optimization
GEO optimizes for citation inside AI-generated summaries — Google AI Overviews, Bing Copilot, Perplexity's source cards. Where AEO is "did the assistant name you?", GEO is "did the generated answer link to you as a source?". It rewards structured data, authoritative outbound sourcing, brand mentions across the web, and clearly named entities.
Do this to earn citations
- Schema.org on every template (Organization, WebSite, Article/Product/LocalBusiness as fits)
- Definitional paragraphs and data tables generative models love to quote
- Consistent brand + entity naming across your site and third-party profiles
- Digital PR: earned mentions on sites the models already trust
Where they overlap
About 70% of the work is shared: crawlability, page speed, structured data, clear headings, entity clarity, and authority signals help all three. The remaining 30% is discipline-specific — link building and rich results for SEO, answer formatting and llms.txt for AEO, schema depth and citation-worthy content for GEO. Build the shared base once, then layer the specifics.
The order to work on them
- SEO first. Fix technical + on-page. If Google can't index you, no AI can either.
- AEO second. Restructure answers, add FAQPage schema, publish llms.txt, allow AI crawlers.
- GEO third. Deepen schema, tighten entities, earn mentions on sites the models cite.
- Measure all three. Rankings for SEO, prompt tests for AEO, citation share for GEO.
Frequently asked questions
No. AEO extends SEO — the same crawlable, authoritative content that ranks in Google is what assistants read to build answers. SEO is the base; AEO adds answer formatting and entity clarity.
AEO is about being named in the assistant's reply. GEO is about being cited as a source inside a generated summary (AI Overviews, Copilot). Different surface, overlapping tactics.
Not a separate strategy — a layered one. Build one content and technical foundation, then add AEO answer formatting and GEO schema on top.
Run prompt tests in ChatGPT, Perplexity, and Google AI Mode for your target queries. Track how often your brand is named or cited over time.
