Reported, not operator documented
Huawei has not published a crawler page that names PanguBot. It is listed here on our own evidence. Verified by AI Crawler Check: 192 of the 5,583 valid robots.txt files in the Tranco top 10,000 carry a rule for PanguBot, so site owners treat it as a real crawler name (how we measure this). That proves the spelling is in use, not who sends it. Reported Huawei PanGu training crawler. No vendor page.
What that means for you: the PanguBot rule on this page is the best available spelling, but Huawei has made no statement of purpose, crawl rate or robots.txt compliance. Treat a PanguBot request in your logs as a clue, not proof of who sent it, and add a firewall rule if that traffic matters to you. If the operator publishes documentation, this profile moves to Official docs.
What is Huawei PanguBot?
Huawei PanguBot is an AI data-collection crawler operated by Huawei. It gathers public web content to build or refine training datasets for large language models. Like other AI training crawlers, Huawei PanguBot does not influence your search-engine rankings, so you can block it via robots.txt without any SEO penalty if you wish to opt out of AI training.

Huawei PanguBot uses the user-agent token PanguBot. You can control it via robots.txt, meta tags (noai), or the emerging llms.txt standard. Robots.txt is voluntary; for hard enforcement, combine it with server-level IP blocking.

How to block Huawei PanguBot with robots.txt
<code>User-agent: PanguBot</code> - Matching is case-insensitive. Robots.txt is fetched from the root of each subdomain separately.
Is Huawei PanguBot safe to allow?
What does Huawei PanguBot do?
Understanding Huawei PanguBot's purpose helps you decide whether to allow or block it.
- Collects public web content to train large language models
- Builds and refreshes AI training datasets
- Harvests text, code, and structured data for model improvement
- Does NOT affect search-engine rankings
- Can be blocked to opt out of AI training without SEO loss
Huawei PanguBot in context
Huawei PanguBot is a training crawler operated by Huawei. In plain terms, it collects pages to train AI models. Our database files it under AI and LLM crawlers and ranks it Tier 2, important crawlers from established AI and search operators. 74 of the 104 AI and LLM crawlers in our database share this tier.
Its safety rating is safe and its blocking impact is low. So the decision about Huawei PanguBot rests on what you want from Huawei, not on its behaviour. How we rate safety and impact.
How site owners treat Huawei PanguBot
In our own scan of the Tranco top 10,000 (5,583 valid robots.txt files), 192 files (3.4%) name PanguBot in a User-agent line. That shows site owners treat the token as a real crawler worth a rule. It does not, on its own, prove who operates it.
Does it follow robots.txt?
Huawei PanguBot's operator does not clearly document how it treats robots.txt. Write the Huawei PanguBot rule anyway, then confirm in your logs that its requests stop.
Huawei crawlers and close alternatives
Huawei PanguBot is one of 2 Huawei crawlers in our database. A User-agent: PanguBot group controls Huawei PanguBot only; the other Huawei tokens below need their own lines.
PanguBot: this crawler (Tier 2)PetalBot: Petal Search, builds a search or answer index (Tier 3)
To give Huawei PanguBot the same answer as its siblings, stack User-agent: PanguBot with their lines above one set of rules; to treat Huawei PanguBot differently, give it its own group.
Other AI and LLM crawlers that do the same job (collects pages to train AI models) include ClaudeBot from Anthropic, Google-Extended from Google, GPTBot from OpenAI, Meta-ExternalAgent from Meta, AI2Bot from Allen Institute for AI, aiHitBot from aiHit. Deciding about Huawei PanguBot is usually a decision about the whole group, so check how your file treats these too.
We first recorded PanguBot on March 17, 2026. We could not find a page where Huawei names it, so treat the token as reported rather than documented.
Which rule Huawei PanguBot actually follows
Huawei PanguBot reads exactly one group in robots.txt, the most specific one that names PanguBot, and never combines rules across groups. This short file shows the trap:
User-agent: *
Disallow: /private/
User-agent: PanguBot
Disallow: /drafts/- Find the group. Huawei PanguBot looks for a group naming
PanguBot. One exists, so it ignoresUser-agent: *completely. - Apply only that group. It is refused
/drafts/and nothing else. - The surprise.
/private/is open to Huawei PanguBot, because that rule lives in the*group it no longer reads. To keep it out of both, repeatDisallow: /private/inside its own group.
Test yourself: does a rule under User-agent: * apply to Huawei PanguBot if the file also has a User-agent: PanguBot group?
No. Once a group names it, Huawei PanguBot reads only that group. Put every rule you want it to follow inside its own group.
Test yourself: will blocking Huawei PanguBot remove your pages from AI answers?
No. Huawei PanguBot collects training data. Blocking it changes what future models learn, not which pages AI answers cite today.
Test yourself: is User-agent: pangubot the same as User-agent: PanguBot?
Yes. RFC 9309 makes user-agent matching case-insensitive. Paths are a different story: Disallow: /Blog/ does not block /blog/.
Should you allow Huawei PanguBot? Decide by situation
| If you are... | Recommended setting |
|---|---|
| You publish content and want AI answers to cite it | Your call. Huawei PanguBot is a training crawler, so blocking it does not remove you from AI answers; retrieval crawlers do that job. |
| You license content and want to stop AI training | Block it by name with User-agent: PanguBot and Disallow: /. |
| You run an online shop | Allow it unless your logs show it is costly. |
| Your server is under load from bots | Rate-limit before blocking. It is rated safe in our database. |
Check Huawei PanguBot on your own site
- Open
/robots.txton your domain and search forPanguBot. If it is not named, it followsUser-agent: *. - List the
Disallowlines in the group Huawei PanguBot follows and test your key URLs against them; the longest match wins, andAllowwins a tie. - Look beyond the file. A firewall or bot manager can refuse Huawei PanguBot even when robots.txt allows it, and that never shows in the file.
- Run our AI visibility checker to see how Huawei PanguBot and every other crawler we track are treated in one pass, including firewall refusals.
Common mistakes with Huawei PanguBot
The errors we see most often with Huawei PanguBot in the files and firewalls we test:
- Assuming that blocking Huawei PanguBot removes you from AI answers. It is a training crawler; AI answers are fed by retrieval and user-triggered crawlers with different tokens.
- Blocking Huawei PanguBot with a broad
User-agent: *rule that also catches search engines. NamePanguBotin its own group instead. - Expecting a Huawei PanguBot block to remove content already collected. robots.txt only affects future visits.
All three hide inside a file that looks correct, so check Huawei PanguBot from outside after every change.
Spotting Huawei PanguBot in your logs
robots.txt says what Huawei PanguBot may do; your access logs show what it actually did.
Count requests
On a server with standard Nginx or Apache logs, this counts matching requests per day (adjust the log path for your host):
grep -iE "PanguBot" /var/log/nginx/access.log \
| awk '{print $4}' | cut -d: -f1 | sort | uniq -cAnd this shows which paths it requested most, which is the quickest way to see whether your Disallow lines are being respected:
grep -iE "PanguBot" /var/log/nginx/access.log \
| awk '{print $7}' | sort | uniq -c | sort -rn | head -20Check the requests are genuine
Anyone can send the Huawei PanguBot user-agent, so confirm the source before acting on a match:
PanguBot: we hold no published IP list, so use reverse DNS where the operator documents a hostname and treat an unverifiable Huawei PanguBot request with caution.
Frequently Asked Questions
What user-agent string does Huawei PanguBot use?
PanguBot. Evidence that the spelling is in real use comes from our own robots.txt study: 192 of the 5,583 valid robots.txt files in the Tranco top 10,000 name it (fetched October 20, 2026), not from Huawei, which has not published crawler documentation naming it. Use it in robots.txt as the best available match, and treat a request carrying it as a clue rather than proof of who sent it.Is Huawei PanguBot safe?
Will blocking Huawei PanguBot hurt my SEO?
User-agent / Disallow: / without any SEO penalty.How do I block Huawei PanguBot in robots.txt?
/robots.txt file:User-agent: PanguBot Disallow: /
This instructs Huawei PanguBot not to crawl any path on your site. To block only specific sections, replace / with the path (e.g.,
Disallow: /blog/).Does Huawei PanguBot respect robots.txt?
PanguBot will stop a client that chooses to honour it; for enforcement, add a firewall or CDN rule as well.How do I verify if Huawei PanguBot is crawling my site?
PanguBot (for example grep -i "PanguBot" /var/log/nginx/access.log). Because the operator publishes no IP ranges or reverse-DNS pattern, a match shows that something used the name, not that Huawei sent it.
