Alibaba runs it as an answer engine, which means it builds the index an assistant searches when somebody asks it a question. If your page is in that index you can be cited, quoted and linked in the answer. If it is not, you are not ranked lower — you are absent from the answer entirely, and no report anywhere will tell you so.
What blocking it costs you: Qwen and the Tongyi assistant answer a very large Chinese-speaking audience without you in the sources. You disappear from that assistant’s answers. Not ranked lower — absent, with no message anywhere telling you it happened.
The user agent, and the token a rule matches on
These are two different strings and confusing them is why a rule that looks right does nothing.
A robots.txt rule matches on the product token, case-insensitively, and
ignores the rest of the user-agent header entirely.

Answer engine
Full user agent
Not published by Alibaba. Match on the token above.
Where an operator has not published the exact string, this page says so rather than
inventing a plausible one. A user agent you can grep your logs for is worth nothing if it is a guess.
Allowing TongyiBot
Paste this into robots.txt at the root of your domain.
An empty Disallow: and Allow: / mean the same thing to a crawler. What does
not mean the same thing is having no rule at all: absence is permission by default, but it is
permission nobody wrote down, and it survives only until somebody adds a blanket
User-agent: * block without thinking about this crawler.
Blocking TongyiBot
User-agent: TongyiBot
Disallow: /
Before you paste that: qwen and the Tongyi assistant answer a very large Chinese-speaking audience without you in the sources. That is the cost, and it is paid silently — no error appears in your logs, no report tells you, and the traffic you lose was traffic you never saw arrive.
How the web actually treats TongyiBot

No site is named, here or anywhere else on this domain. The count is the useful part; a league table of
businesses that never asked to be measured is not.
The row worth reading twice is the last one. 54 of 292 sites have written no rule about
TongyiBot at all, which means their position on it is an accident rather than a decision — whatever
their User-agent: * block happens to say.
Checking what your site does right now
Reading your own robots.txt is not the same as knowing what a crawler concludes from it.
Precedence between a User-agent: * group and a named one, the longest-match rule between
overlapping paths, and a token you spelled slightly wrong all produce a file that looks correct and
behaves otherwise.
npx axray-cli your-site.com
The scan resolves your file against all 54 crawlers on this list individually and reports
which ones are allowed, blocked, or covered by nothing. It is free, needs no account, and installs nothing.
Questions people ask about TongyiBot
What is TongyiBot?
TongyiBot is an answer engine operated by Alibaba: it builds the index an assistant searches when somebody asks it a question. If your page is in that index you can be cited, quoted and linked in the answer. If it is not, you are not ranked lower — you are absent from the answer entirely, and no report anywhere will tell you so.
Should I block TongyiBot in robots.txt?
Only if you are willing to pay what it costs. Qwen and the Tongyi assistant answer a very large Chinese-speaking audience without you in the sources. You disappear from that assistant’s answers. Not ranked lower — absent, with no message anywhere telling you it happened.
What is the TongyiBot user agent string?
Alibaba does not publish a full user-agent string for this crawler. The robots.txt product token is TongyiBot, and that is what a rule matches on; matching is case-insensitive.
How do I check whether my site is blocking TongyiBot right now?
Scan your site with AXRAY. It resolves your robots.txt against 54 named AI crawlers individually rather than reporting one verdict for all of them, so it will tell you whether this specific crawler is allowed, blocked, or covered by no rule at all. It is free and needs no account.
