Cloudflare splits search from AI training
Cloudflare’s new setting lets sites stay visible in search while refusing AI training by mixed-use crawlers.
In brief
Cloudflare’s new setting lets sites stay visible in search while refusing AI training by mixed-use crawlers. Site owners no longer have to choose between search traffic and blocking AI training, but AI summaries are the next fight. Originally reported by Cloudflare Blog.
The old tradeoff
Some major crawlers serve both search indexing and AI training. Blocking them could also make a site harder to find in search.
“Refuse one, and you refuse the other.”
A new middle path
Cloudflare is launching Disallow AI Training, a setting meant to keep search indexing on while refusing use of site content for AI training.
Big crawlers sign on
Apple, Google, and Microsoft already honor the setting or have promised to honor it on a stated timeline.
Summaries come next
Cloudflare says AI summaries need finer controls too. A full yes or no is too blunt when the real issue is how much content appears.
“A site-wide yes or no is too blunt”
Publishers need visits
Most sites want to be found, but many depend on ads, subscriptions, or direct visitor ties. Those models break when people never arrive.
Search is welcome
Fewer than 1% of Cloudflare sites block search bots. By contrast, 17% use some method to block AI training.
Robots.txt is limited
A robots.txt file can state a preference, but it cannot prove who is crawling, why they are crawling, or stop a bot that ignores it.
Cloudflare can enforce
Cloudflare says its network can publish preferences, identify crawlers, classify their purpose, block violators, and report behavior on Radar.
Accountable crawlers
Cloudflare created an Accountable label for crawler operators that give site owners control, visibility, and search protection.
Four promises required
Operators must support training opt-outs, summary opt-outs, URL-level visibility, and assurance that training opt-outs will not hurt search ranking.
Three crawler behaviors
Cloudflare now classifies crawler controls as Search, Training, and Agent. A mixed-use crawler is one crawler doing both Search and Training.
Block means block
With Disallow AI Training available, Block and Block on pages with ads now apply to mixed-use crawlers too, including Applebot, Bingbot, and Googlebot.
Four control choices
Training controls now include Allow, Disallow AI Training, Block on pages with ads, and Block. Disallow AI Training is available only for Training.
September 15 changes
Cloudflare is deprecating Block AI Bots and Managed Robots.txt. Existing customer settings will migrate into the new Search, Training, and Agent controls.
Most users do nothing
Cloudflare says current settings carry over in almost every case. Anyone who wants mixed-use crawlers gone entirely must choose Block.
“Nothing, in almost every case.”
Ads get stricter presets

New domains get preset recommendations based on ad monetization. Sites with ads are nudged toward blocking training and limiting agents on ad pages.
Crawler details differ
Applebot and Googlebot already support training opt-outs through Applebot-Extended and Google-Extended. Bingbot support through robots.txt is targeted for early 2027.
Summaries cut both ways
Cloudflare cites data that summaries can reduce visits, while AI search referrals may convert three to five times better than traditional search referrals.
Control, not one answer
A publisher may need visitor volume, while a retailer may prefer fewer visitors with higher purchase intent. Cloudflare wants to give each site the controls to decide.
At a glance
Site owners no longer have to choose between search traffic and blocking AI training, but AI summaries are the next fight.
