LLM VISIBILITY CHECKER Is your website visible to AI?

AI-powered search and chatbots are changing how customers discover brands. If your site isn’t visible to Large Language Models (LLMs), you’re missing out on future traffic and revenue. Use our quick checker to see how your business appears in major LLMs—and get a simple, actionable report.

Why LLM visibility matters

Search is evolving. More customers are using AI assistants and chatbots to find answers, products, and recommendations. If your website isn’t in their training data, you’re invisible to these new discovery channels.

What’s at stake?

LLMs like ChatGPT, Gemini, and Perplexity are shaping buying decisions. Brands that show up get the first shot at new leads. Those that don’t? They’re left behind as AI becomes the default way people search.

How our checker works

We scan your website’s presence in major LLMs (like ChatGPT, Gemini, and Claude). You’ll get a clear, jargon-free report showing where you’re visible—and where you’re missing out.

What you get

A simple, introductory report: see how your site appears to AI, spot gaps, and get practical steps to boost your visibility. No fluff. No hard sell. Just clarity.

Get your free LLM Visibility Report. It couldn’t be easier!

Just complete our simple form below. We’ll have your LLM Visibility Report to your email address within 1 working day. No hassle, no hard sell.

Step 1 of 3

First - tell us which company you would like to produce the report for. Give us the full name and website address (URL).
We analyse your website to understand the types of search terms & prompts you’re most likely to appear for.

What’s in the Report?

Your free report examines a number of key LLM prompts that we infer from your website content, based on the themes, services and language used across the site. It is designed to give you an initial sense of how your business may appear in AI-generated responses, and how visible you may be in tools such as ChatGPT, Claude and Google Gemini.

It isn’t exhaustive, of course, and should be seen as a directional snapshot rather than a full audit. However, it does give you a useful sense of your competitive position within these emerging AI platforms, including which kinds of prompts your business appears relevant for, where competitors may be more prominent or better represented, and how your current content may be performing from a GEO, generative engine optimisation and LLM optimisation perspective.

If this is helpful, we would be very pleased to conduct a more rigorous audit and examination of your visibility, including a broader prompt set, a deeper competitor comparison, and more detailed recommendations on how your website content could improve its performance in AI-generated search and answer environments.

Main LLMs examined
  • ChatGPT (OpenAI)

    ChatGPT is crucial for brand discovery because it shapes how users explore options through conversational answers rather than traditional search results.

  • Gemini (Google)

    Gemini matters for brand discovery as it integrates deeply with Google’s search ecosystem, influencing which brands appear across AI-powered search experiences.

  • Claude (Anthropic)

    Claude is important for brand discovery because it delivers thoughtful, context-rich responses that can position brands as trusted solutions within longer-form decision-making conversations.

Why does LLM visibility matter?
LLM visibility isn’t just a technical detail – it’s a new competitive edge. As AI assistants and chatbots become gatekeepers to information and services, brands that are visible in LLMs will be chosen, cited, and trusted. If you’re not optimised for AI discovery, you risk being invisible to tomorrow’s customers – and missing out as automated assistants increasingly make decisions on their users’ behalf.
  • Clear, Authoritative Content

    Ensure your site is accurate, up-to-date, and demonstrates expertise. LLMs favour sources they trust.

  • Technical SEO Foundations

    Solid site structure, schema markup and crawlability help LLMs find and understand your pages.

  • Brand Mentions & Backlinks

    The more your brand is referenced across the web, the more likely LLMs are to trust and cite your site.

  • Consistent, Accessible Information

    Key facts, contact details and your brand story should be easy to find and consistent everywhere.
