For twenty years, "search" meant a page of blue links. That is changing. More people now ask a question and get a single, synthesised answer from an AI, whether that is Perplexity, an AI overview at the top of Google, or an assistant built into their browser.
When an AI answers instead of listing links, the game shifts from "rank on page one" to "be the source the AI trusts and cites."
What actually changes
The fundamentals still matter, clear, useful content on a fast, well-structured site, but a new layer sits on top. AI systems favour content they can read cleanly, understand as facts about a real entity, and quote with confidence.
Be readable to machines — clean HTML, real text (not buried in scripts), and structured data that spells out who you are.
Answer real questions — plain, direct content that resolves the thing someone actually asked.
Be a consistent entity — the same name, details and story everywhere, so an AI can join the dots.
Old SEO asked, "how do we rank?" The new question is, "when an AI answers for us, is it getting us right, and crediting us at all?"
The practical move
This discipline has a name, Generative Engine Optimisation, but the work is sensible either way: publish genuinely useful content, keep your site fast and machine-readable, and describe your business consistently. Do that and you stay findable whether the customer scrolls a results page or simply asks.
FAQ
Frequently asked questions
Quick answers to the questions this topic raises most often.
What is Generative Engine Optimisation (GEO)?
It is the work of making your content easy for AI systems to read, understand and cite when they answer someone's question. In practice it means clean HTML, real text rather than content buried in scripts, structured data describing who you are, and genuinely useful answers.
Does AI search mean SEO is dead?
No. The fundamentals still matter: clear, useful content on a fast, well-structured site. AI search adds a layer on top, being readable by machines and consistent as an entity, rather than replacing what came before.
How do I get my business mentioned by AI assistants?
Publish content that directly answers real questions, keep your site fast and machine-readable, describe your business consistently everywhere it appears, and use structured data. AI systems favour sources they can parse cleanly and quote with confidence.
What is an llms.txt file?
It is a plain-text file at the root of a site that summarises what the business does and points to its most useful pages, written for AI systems rather than people. It is an emerging convention, cheap to add, and it makes your site easier for assistants to understand.
