What it is

YouBot indexes public pages for You.com's search engine and cited AI answers. Aiola classifies it as indexing because it supports a searchable retrieval index.

In Aiola's taxonomy, Indexing means crawled for ai or search indexing.

User agent

Look for the match token inside the complete HTTP User-Agent header. Tokens can be spoofed, so use the network checks below for authentication.

Official IP ranges

You.com has not published official IP ranges that Aiola successfully fetched for YouBot. Aiola does not list cloud-provider ranges or community guesses as if they authenticated this crawler.

Verify authenticity

Start with the source IP recorded by your trusted edge or server, not an untrusted forwarded header.

Reverse- and forward-DNS double lookup
host REQUEST_IP
# Confirm the hostname ends in an official suffix
host RETURNED_HOSTNAME
# The forward lookup must return REQUEST_IP

For production checks, test against every current prefix in the vendor feed. Re-fetch feeds regularly: a July 2026 snapshot is evidence of publication, not a permanent firewall list.

Control it with robots.txt

You.com documents crawler controls for this bot family. Robots.txt can direct cooperative crawling, but it cannot prove that a request is authentic.

YouBot indexes public pages for You.com's search engine and cited AI answers. Aiola classifies it as indexing because it supports a searchable retrieval index.

What user-agent token identifies YouBot?

Match the case-insensitive token “YouBot” in the User-Agent header. A matching header alone does not authenticate the sender.

Can I verify YouBot by IP address?

No official YouBot CIDR snapshot was successfully fetched for this verification date. Do not treat an arbitrary cloud IP as proof of identity.

Can robots.txt block YouBot?

You.com documents crawler controls for this bot family. Robots.txt can direct cooperative crawling, but it cannot prove that a request is authentic. Use the specific “YouBot” group when you want a rule for this identity without changing rules for every crawler.
