Your shared Claude chats were showing up in Google, Bing and Brave
A missing noindex tag put 'Share with link' chats — code, legal work, even crypto keys — one search away. Here's how to check and pull yours.

What was one search away
A Reddit user found that typing `site:claude.ai/share` into Google surfaced hundreds of shared conversations — lawyers' legal strategy, engineers' code and stack traces, private chats, and reportedly crypto wallet keys — all readable without the owner's sign-off. Every link you ever made public with 'Share with link' was crawlable.
The bug: a missing noindex tag
Claude's public share pages shipped without a `noindex` tag, so crawlers indexed the full chat body, not just a preview. One absent meta line quietly turned 'share this with a teammate' into 'publish this to the open web.'
Audit your share links now
Open Settings → Privacy → Shared Chats and walk every link you've created; revoke anything with code, secrets, or client details. Links stay live until you delete them — deindexing hides a page from search, it does not unshare it.
Google cleared fast — Bing and Brave lingered
Anthropic appears to have added the noindex fix quickly, and Google results for claude.ai/share largely vanished within a day. The catch: the same pages stayed visible longer on Bing and Brave, and cached copies can outlive the original — 'gone from Google' is not 'gone.'
You've seen this exact movie before
OpenAI shipped the identical indexable-share bug in 2025, then killed searchable sharing outright after ChatGPT logs hit Google. If you build any share feature, default to `noindex` on user-generated public URLs and treat 'shareable' as 'indexable' until you've proven otherwise.
