If you've seen AEO, GEO and AIO in the last year and wondered whether you need three new services, you don't. You need one clear understanding of how search is changing, and a short list of things to fix.

In this guide

  5. What to do first

Start with SEO

Search Engine Optimisation is still the foundation. If search engines can't crawl your site, understand what each page is about, or trust your business, nothing built on top will work. Every acronym below assumes the basics are in place: fast pages, clean structure, accurate business details and useful content.

What is AEO?

Answer Engine Optimisation (AEO) is structuring content so that search features and assistants can lift a direct answer from it. Think featured snippets, People Also Ask boxes and voice assistants.

In practice, AEO means finding the questions your customers ask and answering each one clearly, near the top of the right page, in a sentence or two, before going into detail. Headings phrased as questions, short lists and tables help.

What is GEO?

Generative Engine Optimisation (GEO) is improving how generative AI tools such as ChatGPT, Gemini, Perplexity and Google's AI Overviews understand, describe and cite your brand.

These tools assemble answers from many sources. They do better with businesses that are described consistently across the web, publish original and specific information, and are mentioned on sites they trust. GEO is still a young field. Anyone promising guaranteed AI citations is overselling.

What is AIO?

AI Optimisation (AIO) is used loosely across the industry. We use it for the combined programme: SEO, AEO and GEO together, plus the technical work that makes a site easy for AI systems to read, such as structured data, clean HTML and consistent product or service data.

Short version: SEO gets you found. AEO gets you quoted as the answer. GEO helps AI tools describe you correctly. AIO is doing all three as one plan.

What to do first

  1. Fix your facts. Make sure your business name, address, phone, services and hours are identical on your website, Google Business Profile and major directories.
  2. Write a real About page. Who you are, where you work, who runs the business and what you specialise in. AI tools and buyers both look for this.
  3. Answer your top ten customer questions on your site, each in a clear first sentence followed by detail.
  4. Add structured data for your organisation, services and articles.
  5. Ask an AI tool about your business and your category. Note what it gets wrong. That's your baseline.
  6. Earn mentions on trusted sites: reviews, industry directories, partner pages and local press.

None of this is exotic. It's good marketing housekeeping, now with a second audience: the AI systems that increasingly sit between your business and your buyers.

Questions readers ask

Is SEO dead because of AI search?

No. AI search tools rely on web content, and many still use search indexes to find it. SEO foundations matter more, not less.

Which should a small business start with?

Start with SEO basics and AEO-style answers to customer questions. Those also lay the groundwork for GEO.
