Safe Reported AI & LLM Bots

Amazon Q Business

Q: What user-agent string does Amazon Q Business use?

Amazon Q Business is reported to identify itself with amazon-QBusiness . Evidence that the spelling is in real use comes from our own robots.txt study: 35 of the 5,583 valid robots.txt files in the Tranco top 10,000 name it (fetched October 20, 2026), not from Amazon, 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.

Q: Is Amazon Q Business safe?

Amazon Q Business is rated Safe in this directory, meaning there are no credible public reports of abusive crawling under this name. It is a Reported token: Amazon has not published documentation for it, so its purpose, crawl rate and robots.txt behaviour are not confirmed by the operator, and anyone can send the same user-agent string. Allow or block it on its stated purpose, and back the robots.txt rule with a firewall rule if the traffic matters to you.

Q: Will blocking Amazon Q Business hurt my SEO?

✅ No SEO Impact - Blocking Amazon Q Business does not affect your rankings in Google, Bing, or any other search engine. Amazon Q Business is an AI crawler, not a traditional search indexer. You can freely block it via User-agent / Disallow: / without any SEO penalty.

Q: How do I block Amazon Q Business in robots.txt?

Add the following lines to your /robots.txt file: User-agent: amazon-QBusiness Disallow: / This instructs Amazon Q Business not to crawl any path on your site. To block only specific sections, replace / with the path (e.g., Disallow: /blog/ ).

Q: How do I verify if Amazon Q Business is crawling my site?

Search your access logs for amazon-QBusiness (for example grep -i "amazon-QBusiness" /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 Amazon sent it.

Scout's quick take

amazon-QBusiness (Amazon Q Business) fetches pages so Amazon's AI search can answer and cite them. Block it and you can drop out of those answers, so most sites keep it allowed. This profile is built from reported sightings, not vendor documentation.

Reported, not operator documented

Amazon has not published a crawler page that names amazon-QBusiness. It is listed here on our own evidence. Verified by AI Crawler Check: 35 of the 5,583 valid robots.txt files in the Tranco top 10,000 carry a rule for amazon-QBusiness, 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. Amazon Q Business web connector token.

What that means for you: the amazon-QBusiness rule on this page is the best available spelling, but Amazon has made no statement of purpose, crawl rate or robots.txt compliance. Treat a amazon-QBusiness 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.

Is Amazon Q Business safe to allow?

Amazon Q Business is rated Safe in this directory, meaning there are no credible public reports of abusive crawling under this name. It is a Reported token: Amazon has not published documentation for it, so its purpose, crawl rate and robots.txt behaviour are not confirmed by the operator, and anyone can send the same user-agent string. Allow or block it on its stated purpose, and back the robots.txt rule with a firewall rule if the traffic matters to you.

Amazon publishes no IP ranges or reverse-DNS pattern for Amazon Q Business, so the user-agent string cannot be verified. Rate-limit unusual volume instead of trusting the name.

Amazon Q Business in context

Amazon Q Business is a retrieval crawler that feeds AI search answers operated by Amazon. In plain terms, it builds a search or answer index. Our database files it under AI and LLM crawlers and ranks it Tier 3, mid-priority crawlers with a clear purpose but a smaller audience. 15 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 Amazon Q Business rests on what you want from Amazon, not on its behaviour. How we rate safety and impact.

How site owners treat Amazon Q Business

In our own scan of the Tranco top 10,000 (5,583 valid robots.txt files), 35 files (0.6%) name amazon-QBusiness 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?

Amazon Q Business's operator does not clearly document how it treats robots.txt. Write the Amazon Q Business rule anyway, then confirm in your logs that its requests stop.

Amazon crawlers and close alternatives

Amazon Q Business is one of 8 Amazon crawlers in our database. A User-agent: amazon-QBusiness group controls Amazon Q Business only; the other Amazon tokens below need their own lines.

amazon-QBusiness: this crawler (Tier 3)
Amazon Kendra: Amazon Kendra, harvests pages for a dataset or data product (Tier 6)
Amazonbot: Amazon Nova AI, collects pages to train AI models (Tier 2)
AmazonBuyForMe: Amazon Buy For Me, fetches a page when a person asks an assistant or app to open it (Tier 2)
Amzn-SearchBot: Amzn-SearchBot, builds a search or answer index (Tier 3)
Amzn-User: Amazon User Agent, fetches a page when a person asks an assistant or app to open it (Tier 2)
bedrockbot: AWS Bedrock Bot, collects pages to train AI models (Tier 2)
NovaAct: Amazon Nova Act, harvests pages for a dataset or data product (Tier 2)

To give Amazon Q Business the same answer as its siblings, stack User-agent: amazon-QBusiness with their lines above one set of rules; to treat Amazon Q Business differently, give it its own group.

Other AI and LLM crawlers that do the same job (builds a search or answer index) include AddSearchBot from AddSearch, AIWebIndex from Lyrenth, atlassian-bot from Atlassian, AzureAI-SearchBot from Microsoft, Cloudflare-AI-Search from Cloudflare, Cloudflare-AutoRAG from Cloudflare. Deciding about Amazon Q Business is usually a decision about the whole group, so check how your file treats these too.

We first recorded amazon-QBusiness on September 22, 2026. We could not find a page where Amazon names it, so treat the token as reported rather than documented.

Which rule Amazon Q Business actually follows

Amazon Q Business reads exactly one group in robots.txt, the most specific one that names amazon-QBusiness, and never combines rules across groups. This short file shows the trap:

User-agent: *
Disallow: /private/

User-agent: amazon-QBusiness
Disallow: /drafts/

Find the group. Amazon Q Business looks for a group naming amazon-QBusiness. One exists, so it ignores User-agent: * completely.
Apply only that group. It is refused /drafts/ and nothing else.
The surprise. /private/ is open to Amazon Q Business, because that rule lives in the * group it no longer reads. To keep it out of both, repeat Disallow: /private/ inside its own group.

Test yourself: does a rule under User-agent: * apply to Amazon Q Business if the file also has a User-agent: amazon-QBusiness group?

No. Once a group names it, Amazon Q Business reads only that group. Put every rule you want it to follow inside its own group.

Test yourself: will blocking Amazon Q Business remove your pages from AI answers?

Often, yes. Amazon Q Business is a retrieval crawler that feeds AI search answers, so pages it cannot fetch can drop out of the answers or results it supports.

Test yourself: is User-agent: amazon-qbusiness the same as User-agent: amazon-QBusiness?

Yes. RFC 9309 makes user-agent matching case-insensitive. Paths are a different story: Disallow: /Blog/ does not block /blog/.

Should you allow Amazon Q Business? Decide by situation

Recommended setting for Amazon Q Business by type of site
If you are...	Recommended setting
You publish content and want AI answers to cite it	Allow it. Amazon Q Business fetches pages for answers, so blocking it can remove you from them.
You license content and want to stop AI training	Blocking it does not stop training, because Amazon Q Business is a retrieval crawler that feeds AI search answers. Block the operator's training crawler instead.
You run an online shop	Allow it on product and category pages, which are the pages shoppers ask assistants about.
Your server is under load from bots	Rate-limit before blocking. It is rated safe in our database.

Check Amazon Q Business on your own site

Open /robots.txt on your domain and search for amazon-QBusiness. If it is not named, it follows User-agent: *.
List the Disallow lines in the group Amazon Q Business follows and test your key URLs against them; the longest match wins, and Allow wins a tie.
Look beyond the file. A firewall or bot manager can refuse Amazon Q Business even when robots.txt allows it, and that never shows in the file.
Run our AI visibility checker to see how Amazon Q Business and every other crawler we track are treated in one pass, including firewall refusals.

Common mistakes with Amazon Q Business

The errors we see most often with Amazon Q Business in the files and firewalls we test:

Blocking Amazon Q Business while trying to stop AI training. Retrieval crawlers fetch pages so answers can cite them; blocking it can remove you from those answers without affecting training.
Letting a firewall or bot-fight mode refuse Amazon Q Business while robots.txt allows it. The file looks right, but the crawler still gets a 403 or a challenge page.
Forgetting that once a User-agent: amazon-QBusiness group exists, Amazon Q Business ignores every rule under User-agent: *.

All three hide inside a file that looks correct, so check Amazon Q Business from outside after every change.

Spotting Amazon Q Business in your logs

robots.txt says what Amazon Q Business 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 "amazon-QBusiness" /var/log/nginx/access.log \
  | awk '{print $4}' | cut -d: -f1 | sort | uniq -c

And this shows which paths it requested most, which is the quickest way to see whether your Disallow lines are being respected:

grep -iE "amazon-QBusiness" /var/log/nginx/access.log \
  | awk '{print $7}' | sort | uniq -c | sort -rn | head -20

Check the requests are genuine

Anyone can send the Amazon Q Business user-agent, so confirm the source before acting on a match:

amazon-QBusiness: we hold no published IP list, so use reverse DNS where the operator documents a hostname and treat an unverifiable Amazon Q Business request with caution.
