We analyzed the top 1000 websites in the world to identify which sites are already blocking GPTBot. We updated this study Sep 22, 2023.
OpenAI shared details on how to block its GPTBot on Aug 7, 2023. This study looks at how the top 1000 websites are responding. One concern, as an AI detector, is the risk that LLM's will further scrape content and make AI writing tools that become undetectable to AI checkers? This study analyzes how they are responding.
It was first published here Aug 22, updated Aug 29 and this update is Sep 22, 2023.
Summary of Key Findings (Sep 22, 2023 Update):
- 25.9% of the Top 1000 websites are blocking GPTBot
- Top Websites Now Blocking GPTBot Are: Pinterest (most recently added - Sep 11, 2023), Amazon, Quora, Indeed
- Most Large Media/News Publishers are now all Blocking GPTBot: NYTimes, TheGuardian, CNN.com, USAToday, BusinessInsider, Reuters, WashingtonPost, NPR, CBS, NBC, Bloomberg, CNBC, ESPN
- The Top 6 Biggest Websites That First Blocked GPTBot are:
- Amazon.com - Aug 17, 2023

- NYTimes.com - Aug 17, 2023
- Shutterstock.com - Aug 21, 2023
- Wikihow.com - Aug 12, 2023
- CNN.com - Aug 22, 2023 - The Common Crawl Bot is being Blocked 13.9% of the time. CCBot was around before GPTBot but only 5% of websites blocked it as of Aug 1, 2023
- Only 2 Websites are Attempting to Block Anthropic AI: Reuters blocking both anthorpic-ai and claude-web on Sep 11, 2023 & Corriere.it
Google Extended Update - Sep 29, 2023
Google has provided increased ability to control how Google's AI bots use the content on your website.
Announcing on Sep 28 that Google Extended will be used - https://developers.google.com/search/docs/crawling-indexing/overview-google-crawlers
The first 2 websites to block it are abc.net.au, and francebleu.fr
Differences from 1 month ago…
- The Top 100 websites were more likely to block GPTBot then the remaining Top 1000 websites when we ran this study 1 month ago. That difference is now gone 26% of the top 100 and top 1000 sites are blocking GPTBot.
Websites rushing to block GPTBot but other crawlers continue to scrape its content...
It is not clear why some sites would block 1 crawler bot but allow others.
Updated Study Results Data & File:
- Top 1000 Websites Checked Sep 20, by 5pm EST
- 933 of the 1000 websites robots.txt were checked
- GPTBot, ChatGPT-User, CCBot and Anthropic AI bot were all checked
- 242 blocking GPTBot
- 61 Blocking ChatGPT-User
- 130 Blocking CCBot
- 2 Blocking Anthropic AI Bot

it is not clear if "anthropic-ai" and "claude-web" would be effective as there has been no documentation from Anthropic.
Study Method and Data:
If you have any questions about this study please contact us.
Study Method:
- The top 1000 most popular websites in the world were identified
- Each website robots.txt file was inspected to determine if it was blocking GPTBot or other bots
- Some websites robots.txt were not able to be identified/inspected. They were excluded from our analysis. - If the site was found to be blocking GPTBot then Archive.org was used to verify when the website started blocking it.
- Some websites blocked archive.org making the verification of the date the site started blocking GPTBot not possible.

GPTBot Study Findings:
26.15% of the Top 1000 Websites Have Blocked GPTBot
Since the launch of GPTBot 26.15% of the top 1000 websites are now blocking it.
The First “Top 100” Website to Block GPTBot was Reuters.com on Aug 8, 2023
OpenAI launched GPTBot on August 7th and shortly after the first “Top 100” website to block GPTBot was Reuters.com
This can be verified looking at Archive.org and inspecting the timestamp for Reuters Robots.txt page: Click Here
Reuters is also the only website that seems to be trying to block Anthropic and Claude2.

Why Did OpenAI Launch GPTBot Now?
Given that OpenAI has already consumed much of the internet using datasets like the CommonCrawl why launch GPTBot?
There are several possible reasons:
- OpenAI Lawsuits? OpenAI is facing an increasing number of lawsuits, some of which are related to using content without proper permission. See an up-to-date list of OpenAI ChatGPT Lawsuits.
- Public/Government Pressure? Potentially it is part of their follow-through based on the White House open letter they signed.
- Improve Future Models? They state a somewhat vague “Web pages crawled with the GPTBot user agent may potentially be used to improve future models” This statement could mean…
Connecting ChatGPT to the Internet: The GPT-4 knowledge cutoff date is September 2021, this could be one of the steps in fully connecting ChatGPT to the Internet.
Build a Training Dataset: They could use their GPTBot to scrape the web and build a dataset, although I would assume they have very likely already been doing this.
Does this Remove Content from Current LLM Models like ChatGPT?
No, blocking GPTBot does not remove the knowledge that LLM’s have gained by training on existing web content they have already accessed.
What is Web Crawling or Scraping and is it Legal?
Web crawling or scraping is a process where automated software visits websites to gather specific information from their pages. This is commonly used by search engines to index content. While useful, this practice can sometimes be contentious, especially if done without the website owner's consent.
In a 2019 case between Linkedin and HIQ Labs the ability to scrape publicly available websites was upheld. See TechCrunch article or see Decision.
However, some of the current lawsuits against OpenAI seem to be challenging this.
Downside to Blocking GPTBot? Consider the Google Analogy.
While it may seem premature to compare GPTBot to giants like Google, the analogy isn't without merit. The most significant concern for websites considering blocking GPTBot is the potential missed opportunity. As ChatGPT evolves and integrates with the internet more intimately, it could serve a role similar to that of a search engine. By providing users with direct links or references from web sources, ChatGPT can direct significant traffic to those sites. If GPTBot is blocked, that site's content may not be among the recommended sources, essentially sidelining potential visitors. In essence, just as blocking Google would prevent a website from appearing in one of the world's most popular search engines, blocking GPTBot might mean missing out on a burgeoning channel of web traffic.
