CINC tool captures ChatGPT and Claude reference URLs

3 Key Points

  1. What happened

    CINC said on 2026年10月26日 it added a function to its internal GEO/LLMO tool that collects the URLs of pages ChatGPT and Claude referenced when producing an answer.

  2. Why it matters

    Cited URLs and reference URLs do not necessarily match, so companies can now analyze sources that never surface as links in the answer, which they could not see from citations alone.

WHO IT HITSSEO and AI-search-optimization (GEO/LLMO) teams at companies trying to get their products cited by generative AI, who have been judging AI visibility by the links shown in answers, now get a way to see reference pages that are used but never displayed.

Context & Analysis

The premise CINC is pushing back on is a common one: if a company asks ChatGPT or Claude about its products and no link to its own site appears in the reply, it assumes the AI never looked at the site. CINC's point is that this inference does not hold, because generative AI searches the web and assembles an answer from retrieved pages without citing every page it used. The distinction the company draws is between the reference URL — a page the AI used as a source during generation — and the cited URL, the one displayed as a source inside the answer. Its stated trigger was finding cases in its own analysis where information in an answer could not be confirmed on the cited page. Only after that did it extend its internal GEO/LLMO tool, on 2026年10月26日, to collect reference URLs for both ChatGPT and Claude. For companies working on AI search visibility, the practical shift is that citation checks alone give an incomplete picture of which pages the AI actually drew on, and CINC is positioning the gap between the two URL types as the thing worth measuring. Whether the function moves beyond internal use is not addressed.

FAQ
What is the difference between a reference URL and a cited URL?
CINC defines a reference URL as a page the AI used as a source when generating an answer, and a cited URL as a page shown as a source inside the answer. Reference URLs may or may not appear as citations, so the two are not necessarily identical.
Why did CINC build this?
During analysis, CINC found cases where information in an answer could not be confirmed on the cited page. That led it to make reference sources not shown on the answer screen retrievable.
Which AI services does it cover?
The function covers ChatGPT and Claude.
