What is AI visibility?

More and more people no longer search on Google — they ask ChatGPT, Perplexity or Google AI Overviews directly: “Which electrician near me is good?” or “Who builds websites for restaurants?”. These AI systems answer by reading the web — and can only recommend pages they actually understand.

AI visibility (often called “GEO” — Generative Engine Optimization) describes how well your website can be read, understood and cited by such AI systems. Just like classic SEO for Google, but for the new generation of AI search.

Our check fetches your page and tests the most important technical signals — without you installing anything. You get a score from 0 to 100 and see at a glance what already works and where to improve.

How does AI search work?

Classic Google search shows you a list of blue links — you click yourself. AI search works differently: ChatGPT, Perplexity or Google AI Overviews give a finished answer and cite just a handful of sources. If you’re not among those sources, you’re effectively invisible — no matter how good your site is otherwise.

To end up in those answers, AI systems need to be able to do three things: reach your page at all (crawler access), read the content (server-rendered, not just via JavaScript) and understand what it’s about (clear structure, structured data). Some systems read the web live (Perplexity, Google AI, Microsoft Copilot), others rely on training data (ChatGPT) — but the technical foundation is the same in both cases.

The best part: very few businesses actively optimise for AI search yet. Competition is low — whoever lays the technical groundwork now gains an edge, just like classic Google SEO 15 years ago.

What we check

These factors decide whether AI systems find and understand your site:

Access for AI crawlers

Many sites accidentally block GPTBot, ClaudeBot & co. in robots.txt — making them completely invisible to AI. We check the path is clear.

Content readable without JavaScript

AI crawlers often don’t run JavaScript. If your page loads content only via script, they see a blank page. We measure how much text is directly readable.

Structured data

Machine-readable details (schema.org) about your business, address and offer help AI understand and cite you correctly.

Technical basics

HTTPS, page title, headings, meta description, mobile-friendliness, sitemap & llms.txt — the foundations nothing ranks without.

How to improve your AI visibility

The highest-impact steps when your score is low:

  1. 1

    Don’t block AI crawlers

    Check your robots.txt and remove any blocks for GPTBot, ClaudeBot, Google-Extended & PerplexityBot.

  2. 2

    Serve content server-side

    Make sure your key text sits directly in the HTML and isn’t loaded only via JavaScript.

  3. 3

    Add structured data

    Add schema.org data about your business (name, address, hours, services) — it makes you easier to cite.

  4. 4

    Keep the basics clean

    A meaningful title, a clear H1, a meta description, HTTPS and a sitemap. Sounds simple — yet it’s surprisingly often missing.

Tip

Low score? We build it right.

A site built with Lyba meets all of these automatically: server-rendered, with structured data, clean HTML, a sitemap and every technical basic. Just describe your business — our AI builds a website that humans AND AI can find.

Key terms explained

The jargon around AI search — made clear in one sentence each:

GEO
Generative Engine Optimization — optimising your website to be found and cited by AI answer systems. The AI counterpart to SEO.
LLM
Large Language Model — the AI language model behind ChatGPT, Claude & co. that turns text into answers.
AI Overviews
The AI-generated answer boxes at the very top of Google’s results that summarise content from multiple websites.
GPTBot / ClaudeBot
The web crawlers from OpenAI and Anthropic that read websites for their AI systems. Block them in robots.txt and you’re invisible to that AI.
schema.org
A standard for structured data — machine-readable extra info in your code (e.g. business, address, hours) that AI & search engines understand directly.
llms.txt
A new, optional file (similar to robots.txt) that gives AI systems a curated overview of your key content.

Frequently asked questions

Is the AI visibility checker free?+
Yes, completely free and no sign-up. Just enter your web address and get your result instantly.
What exactly is checked?+
Among other things: whether AI crawlers like GPTBot are allowed, whether your content is readable without JavaScript, whether structured data (schema.org) is present, plus technical basics like HTTPS, title, headings, meta description, mobile-friendliness, sitemap and llms.txt.
Do you store my website data?+
No. We fetch the page once, analyse it immediately and show you the result. No personal data is stored permanently.
What is GEO / AI SEO?+
GEO (Generative Engine Optimization) is optimising your website to be found, understood and cited by AI systems like ChatGPT, Perplexity and Google AI Overviews — the counterpart to classic Google SEO for AI search.
What is an llms.txt?+
The llms.txt is a new, optional file (similar to robots.txt) that gives AI systems a curated overview of your key content. Still optional, but a future-proof signal.
My score is low — now what?+
The recommendations in the result show you the most important issues. If you’d rather skip the tech: a site built with Lyba meets these points out of the box.
Will my site show up in ChatGPT right away?+
Not necessarily right away. ChatGPT partly relies on older training data, while live-searching systems like Perplexity, Google AI Overviews and Microsoft Copilot react faster. The technical basics we check are the prerequisite to be considered at all.
Which AI crawlers are there?+
The main ones are GPTBot (OpenAI/ChatGPT), ClaudeBot (Anthropic), Google-Extended (Google AI/Gemini), PerplexityBot (Perplexity) and CCBot (Common Crawl, the data basis of many models). Our check tells you whether you block these in your robots.txt.
Do I need coding skills to fix things?+
Not for the analysis — that’s one click. For improvements, somewhat. If you’d rather avoid it: a website generated with Lyba ships server-rendered content, structured data, a sitemap and all the basics out of the box.
Is this the same as a normal SEO check?+
There’s overlap (HTTPS, title, sitemap), but the focus differs: we specifically assess what matters for AI answer systems — like whether AI crawlers are allowed and whether content is readable without JavaScript. Classic SEO tools usually don’t check that.
