Cloudflare pilot may raise ai visibility of more web pages
A July research pilot with OpenAI helped ChatGPT discover and index hundreds of millions of pages using Cloudflare’s network signals, Cloudflare says.
Cloudflare ran a research pilot with OpenAI starting in July that helped OpenAI discover and index hundreds of millions of web pages, the companies said. The pilot used about 1% of Cloudflare’s network and early results were shared in an October blog post coauthored by OpenAI staff.
What happened
Cloudflare announced a research pilot with OpenAI on July 8. The companies say the pilot has helped OpenAI discover and index hundreds of millions of previously unknown web pages, increasing the material ChatGPT can draw on, according to Cloudflare’s October 15 blog post coauthored by two OpenAI staff.
The pilot ran on a participating cohort of roughly 1% of Cloudflare’s total network. Cloudflare says its network signals were used to help OpenAI’s search crawler find pages with value and to reduce unnecessary requests.
Cloudflare and OpenAI gave examples of pages surfaced by the pilot, such as a washing machine user guide, up-to-date passport fees and requirements, and a restaurant’s menu and opening hours. The companies also said the signals can flag potentially harmful pages and help identify pages that should be kept out of an index.
The October post reiterates that a signal about a page does not grant permission to access it and points readers to Cloudflare’s AI Crawl Control, which Cloudflare says is available on every plan.
Why it matters for businesses
If AI assistants can discover more pages, businesses may find that additional pages from their sites are visible to users through those assistants. That could include utility pages such as product manuals, updated service requirements or menus and hours that users ask about.
More discovery does not mean automatic citation or inclusion. OpenAI independently evaluates and ranks pages for relevance and helpfulness, and the pilot’s signals are also intended to filter out low-value or harmful pages before they enter an index.
The project shows two practical implications: signals about recency, traffic quality and the nature of page changes can influence whether crawlers consider a page worth visiting, and site owners can use tools such as Cloudflare’s AI Crawl Control to manage how those signals are presented.
Sites that explicitly block OpenAI’s search crawler can avoid being included in ChatGPT’s search results, although the blog post notes that blocked sites may still appear as navigational links. Businesses should therefore check both crawler access settings and their public content to manage ai visibility.
What the AI assistants say today
We checked several AI assistants to see how they reflect the Cloudflare–OpenAI pilot. Some assistants already summarise the pilot’s purpose and effects while others omit or date items inconsistently.
The assistants that reflected the pilot typically cited Cloudflare’s blog and OpenAI developer documents as sources for the pilot’s scope, examples of surfaced pages, the roughly 1% cohort and the distinction between signals and permission to access a page.
| Assistant | Reflects the news? | What it said | Sites it cited |
|---|---|---|---|
| ChatGPT | Partly | The answer captures that Cloudflare and OpenAI ran a pilot that helped OpenAI discover many new pages using Cloudflare signals and that this can increase discovery and citations, but it inaccurately dates the pilot to July 2026 and Oct 21, 2026 and truncates/omits mention of the July 8 announcement and some specific pilot details (cohort size ~1% and examples) present in the news facts. | blog.cloudflare.com, developers.openai.com |
| Gemini | Yes | The answer accurately summarizes the Cloudflare–OpenAI pilot, its scale, effects on discovery and crawling, and recommended actions for site owners. | blog.cloudflare.com, pulse.adyog.com, pymnts.com, webscraper.io |
| Perplexity | Yes | The answer accurately summarizes the pilot's effect—Cloudflare signals helped OpenAI discover and index many new pages (about 1% network cohort), increasing discovery but not guaranteeing citation, and notes practical site-owner steps and controls. | blog.cloudflare.com, dev.to, domhostseo.com, hashe.com, insideai.news, itbrief.com.au |
| Google AI Overviews | Partly | The answer captures that a Cloudflare–OpenAI pilot helps ChatGPT discover and fetch more pages and gives practical implications, but it adds claims (e.g., dramatic immediate indexing, increased server load, and specific product names/settings) and external sourcing not stated or fully supported by the provided news facts. | cloudflare.com, dmexco.com, hashnode.com, instagram.com, msp-channel.com, reddit.com |
What to do now
If you want to manage how your site appears to AI assistants, consider these concrete steps.
- Check your robots.txt for directives that target OAI-SearchBot and GPTBot and decide whether to allow or block those bots according to your visibility goals.
- Use Cloudflare’s AI Crawl Control or equivalent tools to review which signals are exposed and adjust settings for recency, change detection and traffic-quality signals.
- Audit utility pages (manuals, menus, passport or policy pages) for accuracy and clear structure so crawlers and assistants can find and interpret key facts.
- Monitor server logs and bot traffic to see whether crawlers are requesting new pages and whether those requests are helpful or causing unnecessary load.
- Implement filters or meta tags on pages you prefer not to be indexed by assistant search crawlers, and test the result by simulating bot access where possible.
- Periodically review the search and training robot directives in your site documentation to ensure your choices about discovery and training use are still correct.
Questions
Did the pilot increase how many pages ChatGPT can access?
Cloudflare and OpenAI say the pilot helped OpenAI discover and index hundreds of millions of new web pages, which gives ChatGPT more sources to draw on for finding timely information, according to Cloudflare’s October 15 post.
How large was the part of Cloudflare’s network used in the pilot?
The companies say the research pilot used a participating cohort of about 1% of Cloudflare’s total network.
Does a Cloudflare signal give OpenAI permission to crawl a page?
No. The October blog post explicitly states a signal about a page does not grant permission to access it.
Can businesses stop OpenAI’s crawlers from indexing their site?
Yes. The documentation distinguishes between OAI-SearchBot and GPTBot. If a site blocks OAI-SearchBot it will not be included in ChatGPT’s search results, although the post notes blocked sites may still appear as navigational links.
Are measures in place to keep harmful pages out of an index?
Cloudflare and OpenAI say they are testing signals that flag potentially harmful pages, and early results suggest those signals can help identify pages that should be excluded from an index.
