Safe Reported Social Bots

Quora-Bot

Q: What user-agent string does Quora-Bot use?

Quora-Bot is reported to identify itself with Quora-Bot . Evidence that the spelling is in real use comes from our own robots.txt study: 56 of the 5,583 valid robots.txt files in the Tranco top 10,000 name it (fetched October 20, 2026), not from Quora, 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 Quora-Bot safe?

Quora-Bot is rated Safe in this directory, meaning there are no credible public reports of abusive crawling under this name. It is a Reported token: Quora 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 Quora-Bot hurt my SEO?

🔶 AI Visibility Trade-off - Blocking Quora-Bot will not hurt Google or Bing rankings, but it can remove your content from AI search answers and assistant citations powered by this crawler. Block only if you have a deliberate reason.

Q: How do I block Quora-Bot in robots.txt?

Add the following lines to your /robots.txt file: User-agent: Quora-Bot Disallow: / This instructs Quora-Bot 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 Quora-Bot is crawling my site?

Search your access logs for Quora-Bot (for example grep -i "Quora-Bot" /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 Quora sent it.

Scout's quick take

Quora-Bot fetches your page to build the preview card when someone shares a link. Blocking it leaves shared links without a title or image. This profile is built from reported sightings, not vendor documentation.

Quick Facts

User-Agent:: Quora-Bot
Category:: Social Bots
Operator:: Quora
Safety:: Safe
Blocking Impact:: Low - No SEO ranking impact

Evidence:: Verified by AI Crawler Check: in 56 top-10k robots.txt files

Reported, not operator documented

Quora has not published a crawler page that names Quora-Bot. It is listed here on our own evidence. Verified by AI Crawler Check: 56 of the 5,583 valid robots.txt files in the Tranco top 10,000 carry a rule for Quora-Bot, 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. Quora link-preview crawler. The Quora help article that named it has been removed.

What that means for you: the Quora-Bot rule on this page is the best available spelling, but Quora has made no statement of purpose, crawl rate or robots.txt compliance. Treat a Quora-Bot 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 Quora-Bot safe to allow?

Quora-Bot is rated Safe in this directory, meaning there are no credible public reports of abusive crawling under this name. It is a Reported token: Quora 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.

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

Quora-Bot in context

Quora-Bot is a utility crawler operated by Quora. In plain terms, it fetches a page to build a link preview when someone shares it. Our database files it under social preview bots and ranks it Tier 5, low-priority crawlers with limited upside for most sites. 8 of the 9 social preview bots in our database share this tier.

Its safety rating is safe and its blocking impact is not documented. So the decision about Quora-Bot rests on what you want from Quora, not on its behaviour. How we rate safety and impact.

How site owners treat Quora-Bot

In our own scan of the Tranco top 10,000 (5,583 valid robots.txt files), 56 files (1%) name Quora-Bot 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?

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

Quora crawlers and close alternatives

Quora runs only this one crawler in our database, so a single User-agent: Quora-Bot group controls everything Quora fetches through it.

Other social preview bots that do the same job (fetches a page to build a link preview when someone shares it) include FacebookBot from Meta, facebookexternalhit from Meta, LinkedInBot from LinkedIn, Pinterestbot from Pinterest, Slackbot from Slack, Slackbot-LinkExpanding from Slack. Deciding about Quora-Bot is usually a decision about the whole group, so check how your file treats these too.

We first recorded Quora-Bot on March 17, 2026. We could not find a page where Quora names it, so treat the token as reported rather than documented.

Which rule Quora-Bot actually follows

Quora-Bot reads exactly one group in robots.txt, the most specific one that names Quora-Bot, and never combines rules across groups. This short file shows the trap:

User-agent: *
Disallow: /private/

User-agent: Quora-Bot
Disallow: /drafts/

Find the group. Quora-Bot looks for a group naming Quora-Bot. 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 Quora-Bot, 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 Quora-Bot if the file also has a User-agent: Quora-Bot group?

No. Once a group names it, Quora-Bot reads only that group. Put every rule you want it to follow inside its own group.

Test yourself: will blocking Quora-Bot remove your pages from AI answers?

Often, yes. Quora-Bot is a utility crawler, so pages it cannot fetch can drop out of the answers or results it supports.

Test yourself: is User-agent: quora-bot the same as User-agent: Quora-Bot?

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

Should you allow Quora-Bot? Decide by situation

Recommended setting for Quora-Bot by type of site
If you are...	Recommended setting
You publish content and want AI answers to cite it	Low stakes either way. It does not decide whether AI answers cite you.
You license content and want to stop AI training	Blocking it does not stop training, because Quora-Bot is a utility crawler. Block the operator's training crawler instead.
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 Quora-Bot on your own site

Open /robots.txt on your domain and search for Quora-Bot. If it is not named, it follows User-agent: *.
List the Disallow lines in the group Quora-Bot 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 Quora-Bot even when robots.txt allows it, and that never shows in the file.
Run our AI crawler access test to see how Quora-Bot and every other crawler we track are treated in one pass, including firewall refusals.

Common mistakes with Quora-Bot

The errors we see most often with Quora-Bot in the files and firewalls we test:

Treating Quora-Bot as an AI or search crawler. Blocking it has little effect on visibility; decide based on load and what it does with your data.
Relying on robots.txt alone when Quora-Bot is rated caution or aggressive. Back the rule with a server-side block.
Blocking Quora-Bot by IP alone. Ranges change; match the token and verify with logs.

All three hide inside a file that looks correct, so check Quora-Bot from outside after every change.

Spotting Quora-Bot in your logs

robots.txt says what Quora-Bot 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 "Quora-Bot" /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 "Quora-Bot" /var/log/nginx/access.log \
  | awk '{print $7}' | sort | uniq -c | sort -rn | head -20

Check the requests are genuine

Anyone can send the Quora-Bot user-agent, so confirm the source before acting on a match:

Quora-Bot: we hold no published IP list, so use reverse DNS where the operator documents a hostname and treat an unverifiable Quora-Bot request with caution.
