LLM SEO tool
Check what language models need to cite you
A language model can only cite a page it can fetch, read, connect to a known company and quote cleanly. Citerank checks each of those steps on your site and shows you where the chain breaks.
Updated
Five steps between your page and a citation
When ChatGPT, Gemini or Perplexity answers with live sources, your page has to survive five steps. Fail any one and it is skipped, no matter how good the content is. Each row below is a check Citerank runs.
| Step | What goes wrong | Citerank check |
|---|---|---|
| 1. Fetch | GPTBot, ClaudeBot or PerplexityBot is blocked by robots.txt, a firewall or a CDN bot rule | View as AI Crawler with its robots.txt check |
| 2. Read | The content only appears after JavaScript runs, and most AI crawlers do not run it | View as AI Crawler, Site Crawler |
| 3. Understand | The model cannot match your site to a clear description of your company | Entity Map, Knowledge Graph Consistency |
| 4. Quote | The answer is buried mid-paragraph instead of in a passage that stands on its own | Passage analysis, passage rewrites |
| 5. Trust | Schema is missing or contradicts the page; authorship and dates are unclear | Schema audit and generator, Page Auditor |

Frequently asked questions
What is LLM SEO?
LLM SEO is the work of getting large language models such as ChatGPT, Gemini, Claude and Perplexity to find, understand and cite your website when they answer questions. It builds on traditional SEO but adds checks that matter more to AI systems: AI crawler access, content that is readable without JavaScript, a clear entity, and passages that can be quoted on their own.
What does an LLM SEO tool do?
It checks each step a language model takes before citing a page (fetching, reading, understanding, quoting and trusting it) and shows where your site fails. A good one also tracks whether the models actually cite you, so you can confirm the fixes worked.
Do language models use Google rankings?
Partly. Google's AI Overviews and AI Mode draw on pages Google already ranks. ChatGPT and Perplexity run their own searches and can cite pages that rank modestly on Google. Strong organic rankings help, but they do not guarantee citations, and pages outside the top ten do get cited.
Should I block or allow AI crawlers?
If you want to be cited, allow the crawlers that fetch pages for live answers, such as OAI-SearchBot, ChatGPT-User, PerplexityBot and Claude-SearchBot. Training crawlers such as GPTBot are a separate decision. Blocking a search crawler means that engine cannot quote your current pages.
Does llms.txt help with LLM SEO?
Not much, based on our testing. In 179 normally phrased questions about 59 sites, content that existed only in llms.txt never reached an AI answer. Read the study. Crawler access, readable content and clear passages matter far more.
Is there a free LLM SEO tool?
Yes. Citerank's free plan includes 10 scans a month across the Citerank Score, the Page Auditor, View as AI Crawler, and the schema and llms.txt generators. No credit card.
