Does PetalBot respect robots.txt?

Yes. The operator documents that PetalBot reads robots.txt and follows Disallow rules for its own token. Rules take effect on the next fetch of the file, which can be hours or days after you publish them.

How do I block PetalBot?

Add the PetalBot token to robots.txt with Disallow: /. If the crawler ignores robots.txt, match the user agent at your CDN or reverse proxy and return 403 there instead.

Q: How do I verify a request really came from PetalBot?

You cannot, at least not from the request itself. Huawei documents the crawler in its webmaster help. Traffic originates from Huawei Cloud ranges but no per-bot list is published. Compare the source IP against hosting and datacenter ranges instead, and rate limit anything that behaves like a crawler.

PetalBot is a bot operated by Huawei that indexes pages so an AI answer engine can cite them. Operated by Huawei to provide search and AI assistant services. It is documented as honouring robots.txt, but no IP range list or reverse-DNS convention is published, so a request carrying this user agent cannot be proven genuine.

robots.txt

Allow or block PetalBot

Paste one of these into the robots.txt file at the root of your domain. Rules are per token, so a block on one crawler leaves every other bot untouched.

Block PetalBot

User-agent: PetalBot
Disallow: /

Blocks every path for this crawler only.

Allow PetalBot

User-agent: PetalBot
Allow: /

Explicit allow. Useful when a wildcard rule above it would otherwise catch this crawler.

Allow, except the pages you never want quoted

User-agent: PetalBot
Allow: /
Disallow: /account/
Disallow: /checkout/
Disallow: /search

Edit the Disallow paths to match your own account, checkout and search URLs.

What blocking actually costs you

Blocking PetalBot takes the site out of the index behind its answers, so it stops being cited there. If referral traffic from AI answers matters to you, block the training crawler instead and leave this one alone.

Block every crawler in the directory at once

Verification

Is that really PetalBot?

A user-agent header is a string the client chooses. Scrapers copy PetalBot precisely because site owners allow it. Huawei documents the crawler in its webmaster help. Traffic originates from Huawei Cloud ranges but no per-bot list is published.

Paste the IP address from your access log below. You will see whether it belongs to a hosting provider, a residential proxy pool or a Tor exit, plus the ASN that announces it, which is what tells you whether the claim holds up.

Datacenter IP detectionNearly every real AI crawler egresses from cloud ranges. A residential IP claiming to be one is the first thing to check.IP reputation checkSee whether the address behind a fake crawler hit has a history of abuse elsewhere.Residential proxy detectionScrapers that get blocked by user agent often come back through residential proxy pools.
