SEO & AEO
SEO vs AEO: what changes when search engines start answering
Answer engine optimisation builds on SEO rather than replacing it. Here is what actually changes, what stays the same, and where to start.
Short answer: SEO helps your pages rank. Answer engine optimisation (AEO) helps your information get selected when a search engine or AI assistant answers a question directly. AEO is not a replacement for SEO — it is built on top of it. If search engines cannot crawl, understand and trust your site, no amount of answer-friendly formatting will help.
What is answer engine optimisation?
Answer engine optimisation is structuring your content and your business information so that answer experiences — AI Overviews in Google, ChatGPT search, Perplexity, Copilot and voice assistants — can understand what you do and use it accurately when someone asks a relevant question.
The shift is in how people search. Instead of typing a few keywords and scanning a list of links, more people now ask a full question and read a summarised answer. Sometimes they click through to a source. Often they do not.
What stays the same
Most of what makes a site good for traditional search still applies:
- Crawlability. Pages need to be reachable, fast and rendered in a way crawlers can read. Content hidden behind heavy client-side scripts, logins or broken links is invisible to everyone.
- Quality and relevance. Content that genuinely answers a need, written by people who understand the subject, still outperforms thin pages written to hit keywords.
- Authority. Evidence that you are a real, credible business — consistent details, a track record, other reputable sites referring to you — matters even more when a machine is deciding whether to repeat what you say.
What changes
1. The answer has to be easy to find
Many business pages open with three paragraphs of scene-setting before saying anything specific. Answer engines, like busy readers, reward pages that state the answer plainly and early, then support it with detail. A useful pattern is to answer the question in the first two sentences under a clear heading, then expand.
2. Facts about your business need to agree everywhere
If your website says you were founded in one year, your social profiles say another, and a directory lists an old address, you become harder to summarise with confidence. Consistent names, services, locations and contact details — on your site and your profiles — make you a clearer “entity” in the systems that build answers.
3. Structured data has to match the page
Schema.org markup in JSON-LD lets you state facts in a machine-readable way: who you are, what services you provide, who wrote an article and when. Google’s guidance for its AI features is explicit that there is no special “AI” schema to add and no AI text file to create — the requirement is that structured data matches the visible text. Used honestly, markup removes ambiguity. Used to inflate — fake reviews, invented ratings — it is a policy violation and a trust risk.
FAQ markup is a good example of how this shifts. Google stopped showing FAQ rich results for all sites in May 2026. The markup is still valid and other systems can read it, so it is worth keeping where real questions and answers appear on the page — but it is no longer a way to take up more space in Google’s results.
4. Measurement is less precise
Search Console tells you which queries brought clicks, and Google counts visits from AI Overviews and AI Mode within its normal Web search data — but it does not separate them out. There is no equivalent, complete report for how often other AI assistants mention you. You can track featured snippets and AI Overview appearances for priority queries, sample assistant answers for the questions that matter most, and watch branded search and direct enquiries — but anyone offering a precise “AI visibility score” is making a lot of assumptions.
SEO and AEO side by side
| Aspect | SEO | AEO |
|---|---|---|
| Goal | Rank pages in results | Be selected or cited in answers |
| Unit of success | A click to your page | Accurate inclusion in an answer, and the visits that follow |
| Content emphasis | Comprehensive pages targeting topics | Direct answers, clear definitions, evidence |
| Technical emphasis | Crawlability, speed, internal linking | All of SEO, plus structured data and entity consistency |
| Measurement | Rankings, clicks, conversions | Search features, sampled answers, branded demand |
Where to start
- Fix the foundations. Indexing problems, slow pages and broken internal links hurt both SEO and AEO. Start there.
- List the questions your customers ask. Sales calls, support emails and enquiry forms are better sources than keyword tools alone.
- Answer them on the right pages. Each service page should define the service plainly, explain who it is for and answer the common questions — visibly, not hidden in an accordion nobody opens.
- Make your business facts consistent. Name, address, services, people. Check your site, your Google Business Profile and your social profiles.
- Add structured data that matches the page. Organisation, services, articles and breadcrumbs — and FAQs only where they genuinely appear. Skip files and markup that promise special AI treatment; Google says none is needed.
- Measure what you can, honestly. Track search features for priority queries and watch enquiries — and treat any AI visibility report as directional.
A note on guarantees
No one controls what an AI assistant says. Any agency promising guaranteed inclusion in ChatGPT answers or Google AI Overviews is overselling. What you can control is how clear, accurate, consistent and useful your information is. That is what makes you a strong candidate — for search engines, answer engines and, most importantly, the people reading them.
If you would like a review of how search engines and AI assistants currently understand your business, our AEO service starts with exactly that.
