PetalBot is a bot in the AI crawlers category, operated by Huawei.
PetalBot is to access both PC and mobile websites and establish an index database which enables users to search the content of your site in Petal search engine and present content recommendations for the user in Huawei Assistant and AI Search services, both services are powered by Petal Search engine.
AI crawlers collect web pages in bulk to build training data for large language models and other AI systems. They take content without sending visitors back. Most publishers block them in robots.txt or at the WAF unless they have a licensing deal with the operator.
Sample user agent strings sent by PetalBot:
Mozilla/5.0 (Linux; Android 7.0;) AppleWebKit/537.36 (KHTML, like Gecko) Mobile Safari/537.36 (compatible; PetalBot;+https://webmaster.petalsearch.com/site/petalbot)Mozilla/5.0 (compatible;PetalBot;+https://webmaster.petalsearch.com/site/petalbot)Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.
PetalBot follows robots.txt, so these rules stop it crawling the paths you choose. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.
User-agent: PetalBot Disallow: /
User-agent: PetalBot Disallow: /private/ Disallow: /search
User-agent: PetalBot Allow: /blog/ Disallow: /
User-agent: PetalBot Allow: / User-agent: * Disallow: /
User-agent: PetalBot group, PetalBot ignores your User-agent: * rules, so repeat any that should still apply.PetalBot from PetalBot's user agent; check Huawei's own documentation if it publishes a different robots.txt name.Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
PetalBot takes articles for AI training without sending readers back, and its page loads count as invalid traffic if your ad tags fire. Decide whether to license, limit or block it, and keep it out of ad requests.
Transfon Security for publishersVisits from PetalBot to your landing pages are not people. Keep them out of conversion, retargeting and audience data so you do not pay to reach a crawler.
Transfon Security for advertisersPetalBot can copy product descriptions, prices and reviews in bulk. Allow it on pages you want AI models to know about and block it on search, cart and account pages.
Transfon Security for e-commercePetalBot can fetch documentation and public app pages at scale. Rate limit it so it does not slow the product for paying users.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows PetalBot by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

Yes. PetalBot follows robots.txt, so a Disallow rule for the PetalBot user agent stops it from crawling the paths you list.
Add "User-agent: PetalBot" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "PetalBot" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so PetalBot may not follow it, and anyone can send PetalBot's user agent, so a fake PetalBot ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
