Is your site ready for AI search and LLMs?

Generative Engine Optimization (GEO) is how you show up in ChatGPT, Perplexity, and AI Overviews. RankForge checks whether you have an llms.txt file, whether AI engines can identify your brand from your schema, and how much of your content is actually in the HTML they read. Paste your URL — free, no account required.

What does this tool check?

llms.txt — the proposed standard that helps LLM crawlers parse your site
Identity schema — Organization or Person structured data AI engines anchor your brand to
Link headers — RFC 8288 Link headers that point agents to your machine-readable resources
Markdown for agents — whether your site serves markdown when an agent asks for it
Rendered content — how much of your content is in the HTML, not hidden behind JavaScript

What problems does this find?

The issues this check most often surfaces on real sites:

  • No llms.txt file to guide AI crawlers
  • Missing Organization/Person schema, so AI can't identify your brand
  • Content hidden behind JavaScript that LLMs don't render

What do I do after the check is complete?

We checked whether AI tools like ChatGPT and Perplexity can easily read and understand your site: whether you have the new llms.txt file, whether your code tells them who your business is, and whether your content is actually readable to them. Here's what's in place and what's worth adding.

  1. 1

    Start with the pages that matter commercially

    Work down the list in order of how much you care about the page, not how bad the number looks. A flagged page nobody needs to find is not worth an hour of your time.

  2. 2

    Fix the cause, not the symptom

    Most findings here are structural: a page is unreachable, under-linked, or competing with another page. Adding one contextual link from a strong, relevant page usually fixes more than editing the page itself.

  3. 3

    Re-run this check to confirm the fix landed

    The check is free and takes a couple of minutes. Re-crawling after a change is the only way to know it worked — and the full audit tracks the difference between crawls for you.

Why llms.txt checker matters for SEO

AI search engines and assistants increasingly answer questions directly, citing the sites they can crawl and clearly understand. Generative Engine Optimization (GEO) is the emerging practice of making your site easy for those systems to read: a concise llms.txt overview, explicit entity schema so the model knows who you are, and content that lives in the server-rendered HTML rather than appearing only after JavaScript runs. None of these are confirmed ranking signals yet — adoption is early and no major AI engine has committed to llms.txt — so treat them as forward-looking hygiene, not a guaranteed traffic lever. The upside is asymmetric: they're cheap to add and position you for a channel that's growing fast.

llms.txt & GEO Checker: frequently asked questions

What is llms.txt?

llms.txt is a proposed standard: a simple /llms.txt markdown file with a short overview of your site and links to your most important pages, so large language models can parse your content efficiently. Think of it as a robots.txt or sitemap aimed at AI crawlers rather than search engines.

Does llms.txt affect my Google rankings?

No. No major search or AI engine has confirmed it uses llms.txt as a ranking signal. It's an emerging, forward-looking standard. RankForge reports it as informational and never lets it affect your SEO health score.

What is GEO (Generative Engine Optimization)?

GEO is optimizing your site to be read, understood, and cited by generative AI engines (ChatGPT, Perplexity, Google AI Overviews) — through clear structure, entity schema, and crawlable content. It complements traditional SEO rather than replacing it.

Is it free?

Yes — the GEO check runs with no account. Create a free account to run RankForge's full structural SEO audit alongside it.
