Answer Engine Optimisation (AEO) vs GEO vs SEO

AEO, GEO and SEO are three overlapping ways to get found online: SEO ranks your site in Google’s blue links, AEO optimises you to be the direct answer in featured snippets and voice results, and GEO optimises you to be cited inside AI answers from ChatGPT, Perplexity and Google AI Overviews. They share the same foundation, clear content and clean structure, but each targets a different way people now find businesses.

The names overlap so much that even marketers argue about them. For a small business owner, the practical point is simpler: people no longer just type keywords and scan links. They ask questions and read one answer. AEO and GEO are about being that answer.

What each one actually means

• SEO (Search Engine Optimisation) — the original discipline. You optimise your pages so Google ranks them high in the traditional list of results. The goal is a click from a results page to your website.
• AEO (Answer Engine Optimisation) — optimising to be the single direct answer: Google’s featured snippet at the top, the answer a voice assistant reads aloud, the “People also ask” box. The goal is to be the answer, not just a link near it.
• GEO (Generative Engine Optimisation) — optimising so generative AI tools (ChatGPT, Perplexity, Gemini, Google AI Overviews) name and cite your business inside the answer they write. The goal is to be the source the AI trusts.

The trend behind all three: search is moving from “ten links to choose from” to “one answer, sometimes with a few citations.” AEO and GEO are responses to that shift.

How they compare

What they share, and where they diverge

Most of the work overlaps:

1. Write genuinely useful content that answers real customer questions.
2. Structure it clearly with sensible headings, short paragraphs and direct answers near the top.
3. Add schema markup so machines understand who you are and what you offer.
4. Keep facts consistent (your name, address, phone, services) everywhere online.

Where they diverge:

• SEO rewards links and authority signals built over time.
• AEO rewards a concise, quotable answer placed right where the question is asked, often a single sentence or short list.
• GEO rewards being a citable, trustworthy source: clear definitions, hard facts, an llms.txt file, and a reputation the AI can verify across the web.

Which should a small business focus on?

You should do the parts that overlap first, then weight your effort by where your customers actually are.

• If you serve a local area (trades, salons, clinics, cafés): nail SEO and your Google Business Profile first, then layer AEO so you win the “near me” and voice answers.
• If customers research before buying (B2B, professional services, considered purchases): GEO matters more, because those people increasingly ask ChatGPT and Perplexity before they ever Google you.
• If you’re starting from scratch: build the shared foundation once, clear content, fast site, schema, consistent facts, and you’re already optimised for all three.

At A1 Digital we treat these as one job, not three. When we build and run a client’s online presence, the same work, clean content, schema, consistent business facts and a citable site, is tuned to rank in Google, win snippets, and get quoted by AI. You can see what that covers on our pricing page.

The bottom line

SEO is not dead, AEO is not a gimmick, and GEO is not just hype. They are three views of the same goal: when someone asks a question your business can answer, you are the answer they get. The businesses that win in the next few years won’t pick one acronym, they’ll get the shared foundation right and let it pay off across all three. Start by making your most important page answer its own question in the first line.
