Is search engine optimisation (SEO) dead now buyers ask AI?

The short answer

Search engine optimisation (SEO) is not dead, but it is no longer the whole job. SEO gets your pages ranked. Answer engine optimisation, or AEO, aims to make your content the source an AI assistant cites or recommends. You need both.

Some buyers now put their questions to an AI assistant before, or instead of, a search engine. That changes where your content has to show up. It does not remove the need to be found by search engines at all.

What SEO is

Search engine optimisation is the work of making your pages easy for search engines to find, understand and rank. Success looks like a strong position in the results for the questions your buyers search, and a click through to your site.

What AEO is

Answer engine optimisation is the work of making your content the answer an AI assistant gives. Tools such as ChatGPT, Claude, Gemini and Perplexity write a reply rather than only show a list of links. Success looks like your company being cited as a source, or named as a recommendation, inside that reply.

Where they overlap and where they differ

The two disciplines have more in common than the "SEO versus AEO" framing suggests.

Where they overlap

Both depend on the same technical foundations:

• Pages that can be crawled. If a page cannot be reached and read, neither a search engine nor an assistant can use it.
• Clear structure. Sensible headings, a logical site layout and a sitemap help any system understand what a page covers.
• Content that answers a real question. A page built around a question buyers actually ask serves both a search result and an AI answer.

Where they differ

The difference is in the result you aim for and how you measure it.

• SEO aims for a ranking. You measure positions, impressions and clicks.
• AEO aims for a citation. You measure whether an assistant names you, links to you or recommends you when a buyer asks a relevant question.

A page can rank well and still never be quoted in an AI answer. That can happen when it circles the question rather than answering it, or when the answer is buried under a long introduction.

Why "SEO is dead" is the wrong way to see it

"SEO is dead" suggests that one channel has replaced another. That is not what changed.

What changed is the shape of the answer. A search engine hands the buyer a list and lets them choose. An assistant can hand the buyer a single written answer with a small number of sources, or none at all. Being on page one matters less if the buyer never sees page one.

But AI assistants still have to get their material from somewhere. Many of them draw on content that is already findable on the web. So the work that makes you findable is still the base. What is new is a second test on top of it: is your content clear and specific enough to be the answer?

"We already have an agency doing SEO"

That is a good starting point, not a reason to switch.

If your agency keeps your site crawlable, well structured and focused on real buyer questions, that work also supports AEO. Nothing needs to be thrown away.

The useful questions to put to your current set-up are narrower:

1. Does anyone check whether AI assistants name or cite you for the questions your buyers ask?
2. Is your content written to answer a question directly, or written mainly to rank for a keyword?
3. Does your reporting show citations and mentions, or only rankings and traffic?

If the answer to all three is no, you do not have an SEO problem. You have a gap next to your SEO work, and it can be filled alongside it.

What to do about it without discarding your SEO investment

Keep the foundations in place

Keep doing the technical work that makes pages findable. Crawlability, site structure and a clean sitemap stay useful for both search engines and assistants.

Write content an assistant can quote

Your content is material an AI assistant can cite. The pieces most likely to be used tend to share a few traits:

• The answer comes first. State the answer in the opening lines, then explain it.
• Each section answers one question. Clear headings make it easier to lift out one part.
• The claims are specific. A plain, defensible statement is easier to quote than a vague one.
• Terms are explained. Define a term the first time you use it, as a buyer would ask about it.

This is also why brand visibility matters beyond search rankings. We cover the difference between being known and being seen in brand awareness vs brand visibility.

Start measuring AI answers

Pick the questions your buyers are most likely to ask. Put them to the assistants your buyers are likely to use. Record whether you are named, cited or left out, and repeat the check on a regular schedule.

This will not be as tidy as a rankings report. It will tell you whether the work is reaching the place some buyers now look first.

Where to start

If your pipeline is thin or your reporting is being questioned, the first step is to find out where you stand. That means checking whether search engines rank you and whether AI assistants recommend you, not only one of the two.
