AI SEO is the practice of structuring your website so AI assistants like ChatGPT, Perplexity, and Google's AI Overviews can find it, read it cleanly, and quote it when answering a user's question. It combines GEO (generative engine optimization) and AEO (answer engine optimization) and sits alongside classic SEO rather than replacing it.

Pillar Guide

AI SEO: How to Show Up in ChatGPT, Perplexity, and Google AI

Q: How is AI SEO different from regular SEO?

Classic SEO aims to rank a clickable link on a results page. AI SEO aims to be the source an AI assistant pulls into its written answer. The goal shifts from a ranked link to a quoted sentence, so clean structure, clear claims, and machine-readable markup matter more than keyword density or backlink volume alone.

Q: How do I check if AI can read my website?

Start with the free tools: the AI Crawler Checker tells you whether AI bots are even allowed to fetch your pages, How AI Reads Your Page shows what an assistant actually extracts, the Answer-Readiness Checker scores how quotable your content is, and the llms.txt Generator builds the map file that points AI to your best pages.

Q: Does AI SEO replace Google rankings?

No. Google still drives most discovery, and Google's own AI Overviews draw on the same well-structured content. The work that makes you quotable by ChatGPT and Perplexity also strengthens classic search. You are adding a channel, not abandoning one.

Q: What is llms.txt and do I need it?

llms.txt is a plain-text map file at your domain root that tells AI systems which pages matter and how to understand your business. It is low-cost to add and signals intent. No major AI provider treats it as a guaranteed input yet, but it is cheap insurance — generate one with the free llms.txt Generator.

Q: How long does AI SEO take to work?

Technical fixes — allowing crawlers, fixing structure, adding schema — can be live in days. Being consistently quoted by AI assistants builds over weeks as they re-crawl and re-index. A free scan shows your current state; the deep audit gives you the prioritised order to fix it fastest.

By Jerome Bilaos·Technical Web Architect·Updated June 2026

More and more of your future customers are not typing a question into Google and scrolling links. They are asking an AI assistant — ChatGPT, Perplexity, Google's AI Overviews, Claude — and reading the answer it writes back. That answer names a few businesses. The rest are invisible.

AI SEO is the work of making sure your business is one of the names the AI mentions. This page is the hub: it explains the idea in plain English, shows how it differs from the SEO you already know, points you to free tools to check your own site, and links the deeper guides for when you want to go further.

What "AI SEO" actually means

AI SEO is shorthand for getting found, read, and quoted by AI assistants. You will see two more precise terms used around it:

GEO (Generative Engine Optimization) — optimizing your content so the systems that generate answers (ChatGPT, Perplexity, Google AI) choose to cite and recommend you.
AEO (Answer Engine Optimization) — structuring your pages so they directly answer the question a person actually asked, in a form an AI can lift cleanly into its reply.

Both come down to the same three jobs, in order:

Found — the AI's crawler is allowed to fetch your page in the first place.
Read — once fetched, the page is clean enough that the AI understands what you do, who you serve, and what you claim.
Quoted — your content is clear and authoritative enough that the AI repeats it in the answer it shows the user.

Miss any one of the three and you are out of the answer. There is no second page of results to scroll to — an AI answer names a handful of sources and stops.

How AI SEO differs from classic SEO

Classic SEO was built around one outcome: rank a clickable link as high as possible on a search results page, then earn the click. The currency was position and traffic.

AI SEO changes the outcome. The AI does not hand the user ten links — it writes a paragraph and names a few sources inside it. So the goal is no longer "rank a link." It is "be the sentence the AI writes."

Classic SEO competes for a ranked link. AI SEO competes to be the quoted source inside the answer itself.

That shift changes what matters:

Clear, self-contained answers beat keyword stuffing

An AI assistant lifts the part of your page that cleanly answers the question. A page padded with keywords but light on direct answers gives it nothing to quote. Say what you do, for whom, and with what result — plainly, near the top.

Structure is now load-bearing

Proper headings, real lists, descriptive links, and structured data (Schema.org markup — a machine-readable label that tells software what a piece of content is) help the AI parse you in one pass. These were "nice to have" for Google. For AI assistants they decide whether you are understood at all.

Being allowed in is a real step

Many sites quietly block AI crawlers in their robots.txt file (the rulebook that tells bots what they may fetch) or behind JavaScript and forms. If the AI cannot fetch or render the page, none of the rest matters. This is the most common silent failure I see.

Trust and authority still count — just differently

AI assistants favour sources that are consistent, specific, and corroborated elsewhere. Vague marketing copy reads as noise. Concrete claims, named outcomes, and clear positioning read as quotable fact.

How to check whether AI can read your site

You do not have to guess. Each of these free tools answers one of the three jobs — found, read, quoted — and none of them needs a signup:

AI Crawler Checker — Found? Tells you whether the major AI bots are actually allowed to fetch your pages, or whether your robots.txt is shutting them out.
How AI Reads Your Page — Read? Shows you what an assistant actually extracts from a URL, so you can see your page through a machine's eyes.
Answer-Readiness Checker — Quoted? Scores how cleanly your content answers real questions and how easy it is to lift into an AI answer.
llms.txt Generator — builds the llms.txt map file that points AI systems straight to your best pages.

Want the full set? There are 12 free tools covering crawlability, schema, entity clarity, and more. Run a few and you will quickly see which of the three jobs is failing on your site.

Go deeper: the two core reads

This hub keeps things at the plain-English level. When you are ready for the detail, these two guides go deep on each half of the work:

How to Make Your Website AI-Readable (GEO Guide) — the content-and-language side: how to write and structure pages so Claude, ChatGPT, and Perplexity cite and recommend you instead of your competitor. Start here if your problem is being read and quoted.
AI-Era Web Architecture: Building Websites for AI Agents — the structural-and-technical side: schema as a real deliverable, llms.txt, semantic HTML, and machine-accessible content. Start here if your problem is being found and parsed at all.

The short version: GEO is what you say and how you frame it; AI-era architecture is the plumbing underneath that lets a machine read it. Most sites need both. These guides cover each properly — this page just points the way.

A simple order to work in

If you do nothing else, do these in this order:

Confirm AI is allowed in. Run the AI Crawler Checker. An accidental block undoes everything else.
See what the machine sees. Run How AI Reads Your Page on your most important URL.
Make your answers quotable. Use the Answer-Readiness Checker, then tighten your copy per the GEO guide.
Fix the structure. Add schema and clean semantic HTML per AI-era web architecture, and publish an llms.txt.

None of this requires rebuilding your site. It requires treating AI assistants as a real audience — one that is already shaping which businesses your customers ever hear about.

From check to fix to ongoing — and the human behind it

The tools above tell you what is wrong. Here is how to actually get it handled, from free to fully done.

1 · Free — see where you stand

Run the free instant website check for a quick score and your top issues, then work through the 12 free tools. No signup, no cost — a fast read on whether AI can find, read, and quote you.

2 · $297 — the deep human audit

The full website audit: 149 checks across 15 categories, reviewed and prioritised into a clear fix list you can hand to any developer — or to me. This is the complete picture, not just a score.

3 · Ongoing — monitoring & monthly scans

For sites that change often, ongoing monitoring with monthly scans and history keeps you visible to AI as the web shifts. This is rolling out — join the list or book a call to be first in line.

Tools and scans find the problem. When you need a Technical Web Architect to actually rebuild the structure — not just flag it — that's me, Jerome Bilaos. I build these tools, and I do the hands-on work behind them: schema, site structure, crawlability, the architecture that makes a site genuinely AI-readable. When a scan tells you what is broken and you want it fixed properly, that is the work I do.
