Why Doesn't ChatGPT Cite Naver Blog Posts?

Naver Blog blocks OpenAI's crawlers

The robots.txt file on Naver Blog (blog.naver.com) blocks both OpenAI's search crawler, OAI-SearchBot, and its training crawler, GPTBot, across the entire site. OpenAI states in its official documentation that sites blocking OAI-SearchBot will not be shown in ChatGPT search answers. As a result, Naver Blog posts do not appear as sources in ChatGPT search answers (as of October 22, 2026).

A crawler is a program that automatically visits web pages and collects their content. robots.txt is the file a site uses to tell crawlers what they may collect. Naver Blog's file includes a comment stating that bot access for AI training and RAG is strictly prohibited. RAG (retrieval-augmented generation) is a method in which an AI looks up and consults external documents when composing an answer.

In this file, nine AI crawlers, including the two from OpenAI, are blocked from the whole site with a 'Disallow: /' rule. All other crawlers are blocked only from certain paths.

This is not the same as 'unable to read at all'

According to OpenAI's documentation, OAI-SearchBot is used to surface websites in ChatGPT's search results. Blocking GPTBot signals that content should not be used to train OpenAI's generative AI foundation models. A blocked site may still appear as a navigational link.

ChatGPT-User, which visits web pages in response to a user's question, is not named in Naver Blog's robots.txt. OpenAI explains that because these visits are initiated by users, robots.txt rules may not apply to them. However, ChatGPT-User is not used to determine whether a site appears in search.

robots.txt rules follow the Robots Exclusion Protocol, published as IETF RFC 9309 in September 2022. The standard defines these rules as requests that crawlers are asked to honor. It also states that they are not a form of access authorization. The real question is not whether a page can be read, but whether it can become a source for search answers.

Keep an official page that your business owns

Every Naver Blog post follows the same robots.txt on blog.naver.com. The practical approach is to keep running your Naver channels while also maintaining an official page your business owns that AI crawlers can read. This page should hold your business information, answers to frequently asked questions, and facts backed by evidence.

On your own domain, you can set rules for each crawler. OpenAI lets you configure OAI-SearchBot and GPTBot separately. You can allow OAI-SearchBot for search visibility while opting out of training by blocking GPTBot.

How AIO2O WebforAI helps

WebforAI is a service that organizes a company's official information so AI can read and cite it accurately. It diagnoses AI answer readiness from a single homepage URL. It checks whether the site answers questions (AEO) and whether it can be cited as a trustworthy source (GEO).

The diagnosis starts by sending real requests the way AI crawlers do, to confirm the site can be read. Items that cannot be verified are excluded from scoring, and each item is labeled with the type of evidence behind it.

Next, official information and sources are organized into an official answer hub in question-and-answer format on a domain the client owns. Structured data and a sitemap are added as well. The existing homepage is not rebuilt. AIO2O then handles site management and maintenance, measuring the same questions repeatedly and reporting before-and-after comparisons.

Rankings and visibility are not guaranteed. The diagnostic score is neither an official search engine score nor a probability of citation. Inquiries are welcome at sales@o2o.kr.
