Search used to mean one thing: ten blue links on Google. Today, the same question might be answered by a Google result, a featured snippet, a voice assistant or an AI assistant such as ChatGPT or Perplexity. Each of those surfaces chooses what to show in a slightly different way. That is where the three acronyms come from.
The three, in one line each
| Term | Stands for | The goal |
|---|---|---|
| SEO | Search engine optimisation | Rank your pages in search results |
| AEO | Answer engine optimisation | Be the direct answer a search engine lifts and shows |
| GEO | Generative engine optimisation | Be understood, trusted and cited by AI assistants |
They are not three separate projects. They are layers on the same foundation, and the work overlaps heavily.
SEO: still the foundation
If search engines cannot crawl, render and understand your site, nothing else matters. Good SEO in 2026 still comes down to a few unglamorous things:
- Crawlable pages. Content should be in the HTML that the server sends, not only drawn by JavaScript after the page loads.
- One clear topic per page, with a single descriptive H1 and headings that outline the page.
- Fast, stable pages on a phone. Google measures Core Web Vitals: how quickly the main content appears (LCP), how stable the layout is (CLS) and how quickly the page responds to taps (INP).
- Clean URLs and redirects. When you rebuild a site, map every old URL to its closest new page with a 301 redirect.
- Content that deserves to rank: written for a real person with a real question, by someone who knows the subject.
AEO: answer first, then explain
Answer engines look for a short, self-contained passage that answers a question directly. You can make that easy for them:
- Lead with the answer. Open the page or section with a 40 to 60 word answer, then add the detail.
- Use the question as a heading where it is natural, for example "How long does a website take?"
- Add FAQ sections with the questions customers actually ask you, written in plain language.
- Mark it up. FAQPage, HowTo, Product and Article structured data tell search engines exactly what each part of the page is.
A useful test: read the first paragraph of any page out loud. If it would make sense as a voice assistant's reply, you are on the right track.
GEO: make your business easy for AI to describe
AI assistants build their answers from what they can find and trust about you across the web. You cannot control what they say, but you can make the accurate version easy to find:
- Consistent entity facts. Your business name, what you do, where you are and how to contact you should match on your website, your Google Business Profile, your social profiles and the directories you appear in.
- Organisation schema on your site, including
sameAslinks to your official profiles. - Quotable statements. Clear, factual sentences such as "Ceylond is an AI, automation and systems studio based in Sri Lanka" are easier to cite than clever slogans.
- An llms.txt file. A short plain-text summary at the root of your site that points AI tools to your key pages. It is new and not every system reads it yet, but it is cheap to add.
- Allow the crawlers you want. Check that your robots.txt does not accidentally block the search and AI crawlers you would like to be found by.
What to do this month
If you only have time for a few things, do these in order:
- Check your site in Google Search Console for indexing problems.
- Rewrite the opening paragraph of your five most important pages so each one answers its main question directly.
- Add FAQ sections, with schema, to your service pages.
- Make your business details identical everywhere they appear online.
- Ask a few AI assistants about your business and your category, and note what they get wrong. Those gaps are your content plan.
