AI SEO: GEO, AEO & How to Get Cited in AI Search

AI SEO is the practice of optimizing your content and brand so AI search engines cite and recommend you in their answers. It's known by several overlapping names — there's no settled consensus, and they're often used interchangeably:

• GEO (Generative Engine Optimization) — getting cited by large language models like ChatGPT, Gemini, Claude and Perplexity.
• AEO (Answer Engine Optimization) — becoming the source of the direct answer in AI Overviews, featured snippets and knowledge panels.
• AIO / LLMO / "AI SEO" — broader labels for the same goal: visibility inside AI answers.

To answer "what is GEO in SEO" and "what is AEO" simply: both are about being the answer an AI gives, not just a blue link a user might click.

Here's the difference (GEO vs SEO, AEO vs SEO) at a glance:

Authority + entity trust

The key point: they overlap heavily and rely on the same foundations. AEO and GEO don't replace SEO — they extend it into AI answers.

Unlike traditional search (a ranked list of links), LLMs synthesize an answer from multiple sources and cite some of them. To be one of those cited sources, your content has to be easy for an AI to find, extract and trust: crawlable, clearly structured, factually solid, and backed by authority and third-party mentions. Pages cited in AI Overviews earned roughly 120% more clicks in a 2026 Seer Interactive study. (Source: seerinteractive.com — verify/link.) Google has also published guidance on optimizing for its generative-AI features. (Source: Google Search Central — verify/link.)

The good news: AI SEO optimization builds on the SEO you already know. Here's how each tactic maps back:

Structure content to be quotable

Lead each section with a direct, self-contained answer, then expand. Use short paragraphs and clear H2s so an AI can lift a clean "chunk." (This is on-page SEO.)

Use FAQs, lists and comparisons

Formats that answer real questions directly — FAQs, step lists, comparison tables — are extracted and cited most often.

Add schema / structured data

Structured data helps AI engines interpret your content and entities. (This is technical SEO.)

Build entity clarity & topical authority

Cover a topic comprehensively and consistently so AI systems understand who you are and what you're expert in — a hub-and-spoke content structure helps.

Earn third-party mentions & citations

LLMs favour sources others cite. Brand mentions and links on authoritative sites make you more likely to be recommended. (This is off-page SEO.)

Keep content accurate and current

AI engines favour trustworthy, up-to-date sources — dated or inaccurate content gets left out.

Traditional rankings don't capture AI visibility. Track instead: citations/mentions in AI answers, brand mentions across the web, referral traffic from AI platforms (ChatGPT, Perplexity), and whether you appear in AI Overviews for your key queries.

No — GEO and AEO enhance SEO, they don't replace it. Generative engines lean on the same authority and relevance signals as traditional search, so strong SEO is the foundation AI visibility is built on. The smart move in 2026 is to keep doing solid SEO and layer GEO/AEO on top.
