What is AI search?
AI search is when search engines and assistants answer a query directly with an AI-generated response — Google AI Overviews, ChatGPT, Perplexity, Gemini — rather than only returning a list of links.
They compose an answer from across the web and cite a few sources. So the game has changed: visibility now means being one of the sources the AI quotes, not just ranking in the blue links.
How AI search differs from traditional SEO
Traditional SEO earns a ranking; AI search earns a citation inside an answer. The good news is that the inputs overlap almost entirely — clear content, good structure, topical authority and trust. What changes is the target: being the quotable answer, not just the top result. It's the natural next chapter of our complete guide to SEO.
Google AI Overviews
AI Overviews are AI-generated summaries at the top of some Google results that answer the query and cite sources. Being included means being quoted above the classic results.
Full breakdown: Google AI Overviews — how to show up.
AEO — Answer Engine Optimization
AEO is optimising to win the single direct answer — featured snippets, voice results and AI answers. It's about being the answer, not one of ten links.

GEO — Generative Engine Optimization
GEO is optimising to be cited inside generative AI answers from tools like ChatGPT and Perplexity — earning a mention within the model's response.

AEO vs GEO vs SEO
They chase visibility in different places: SEO for rankings, AEO for the direct answer, GEO for citations inside generative AI. Most brands need all three, and they share the same foundations.

How to get cited by AI
To be cited, be the clearest, most trustworthy answer: lead with a direct response, structure content well, cover topics thoroughly, and build an external footprint that signals credibility. The exact playbook: how to get cited by ChatGPT.
Voice search
Voice assistants read a single answer aloud, so voice is answer-first by nature — conversational, question-based and often local. Optimise for it with our voice search optimization guide.
Structured data for AI
Schema markup helps both Google and AI engines understand exactly what your content is, which makes it easier to quote. Build valid JSON-LD free with our schema markup generator.
Entities, authority & trust
AI engines favour sources they understand and trust. That means being a clear entity — consistent name, profiles and information across the web — with genuine authority (links, mentions, expertise) and accurate, credible content. Trust is the currency of AI citations.
How to optimize for AI search
- Answer first — open with a concise, liftable answer to the exact question.
- Structure clearly — headings, short paragraphs, tables, and FAQs.
- Add schema — mark up content so engines understand it.
- Build topical authority — cover topics in depth across a cluster, not one thin page.
- Strengthen your entity — consistent brand info and profiles across the web.
- Earn trust & links — credible content and an external footprint.
- Keep ranking — strong SEO underpins AI citations; the two reinforce each other.
Frequently asked questions
What is AI search?
AI search is when search engines and assistants answer a query directly with an AI-generated response instead of only listing links — through Google AI Overviews, ChatGPT, Perplexity and similar tools. They compose an answer from across the web and cite a few sources, so visibility now means being one of those cited sources.
What is the difference between AEO and GEO?
AEO, answer engine optimization, is about winning the single direct answer — featured snippets, voice and AI answers. GEO, generative engine optimization, is about being cited inside generative AI answers from tools like ChatGPT and Perplexity. They overlap heavily and both rely on clear, trustworthy, well-structured content.
Is SEO dead because of AI search?
No. AI answers are built from web pages, and the pages that get cited are usually ones with strong SEO — good content, structure, authority and trust. SEO is evolving, not ending: the same fundamentals now also earn AI visibility. Traditional rankings and AI citations reinforce each other.
How do I get my content cited by AI?
Answer questions directly and concisely, structure content clearly with headings and schema, build topical authority across a cluster, and earn trust through accurate, credible content and an external footprint. AI engines cite sources that are easy to understand, comprehensive and trustworthy — the same traits that win featured snippets.
Should Indian businesses care about AI search yet?
Yes — early movers benefit most. AI Overviews and AI assistants are already shaping how people find information, and competition to be cited is still low. Building answer-first, well-structured, trustworthy content now positions you to be the source AI quotes as adoption grows, rather than playing catch-up later.
