What is Baidu Bookmark?

Baidu Bookmark is an AI search-index crawler operated by Baidu. It collects and indexes web content so it can be surfaced as citations or answers inside Baidu's AI search experience. Allowing Baidu Bookmark can increase your visibility in AI-powered search results, which is why most sites choose to permit it.

Baidu Bookmark in context

Baidu Bookmark is a search engine crawler operated by Baidu. In plain terms, it builds a search or answer index. Our database files it under search engines and ranks it Tier 3, mid-priority crawlers with a clear purpose but a smaller audience. 62 of the 63 search engines in our database share this tier.

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

How site owners treat Baidu Bookmark

Our robots.txt study of the Tranco top 10,000 did not track Baiduspider-favo as a named token, so we do not publish an adoption figure for it. If you run a large site, your own logs are the best evidence of how often it visits.

Does it follow robots.txt?

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

Baidu crawlers and close alternatives

Baidu Bookmark is one of 10 Baidu crawlers in our database. A User-agent: Baiduspider-favo group controls Baidu Bookmark only; the other Baidu tokens below need their own lines.

  • Baiduspider-favo: this crawler (Tier 3)
  • baidu: baidu, builds a search or answer index (Tier 3)
  • Baiduspider: Baidu Search, builds a search or answer index (Tier 3)
  • Baiduspider-ads: Baidu Business Search, checks pages for an SEO, uptime or analytics service (Tier 3)
  • Baiduspider-cpro: Baidu Union, checks pages for an SEO, uptime or analytics service (Tier 3)
  • Baiduspider-image: Baidu Image Search, builds a search or answer index (Tier 3)
  • Baiduspider-news: Baidu News Search, builds a search or answer index (Tier 3)
  • Baiduspider-video: Baidu Video Search, builds a search or answer index (Tier 3)
  • ERNIEBot: ERNIE (Baidu), collects pages to train AI models (Tier 2)

To give Baidu Bookmark the same answer as its siblings, stack User-agent: Baiduspider-favo with their lines above one set of rules; to treat Baidu Bookmark differently, give it its own group.

Other search engines that do the same job (builds a search or answer index) include Amzn-SearchBot from Amazon, Applebot from Apple, bingbot from Microsoft, BingPreview from Microsoft, BingVideoPreview from Microsoft, DuckDuckBot from DuckDuckGo. Deciding about Baidu Bookmark is usually a decision about the whole group, so check how your file treats these too.

We first recorded Baiduspider-favo on September 22, 2026. Baidu documents it on help.baidu.com, and we recheck that page before each release.

Which rule Baidu Bookmark actually follows

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

User-agent: *
Disallow: /private/

User-agent: Baiduspider-favo
Disallow: /drafts/
  1. Find the group. Baidu Bookmark looks for a group naming Baiduspider-favo. One exists, so it ignores User-agent: * completely.
  2. Apply only that group. It is refused /drafts/ and nothing else.
  3. The surprise. /private/ is open to Baidu Bookmark, 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 Baidu Bookmark if the file also has a User-agent: Baiduspider-favo group?

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

Test yourself: will blocking Baidu Bookmark remove your pages from AI answers?

Often, yes. Baidu Bookmark is a search engine crawler, so pages it cannot fetch can drop out of the answers or results it supports.

Test yourself: is User-agent: baiduspider-favo the same as User-agent: Baiduspider-favo?

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

Should you allow Baidu Bookmark? Decide by situation

Recommended setting for Baidu Bookmark by type of site
If you are...Recommended setting
You publish content and want AI answers to cite itAllow it. It is how this search engine finds your pages.
You license content and want to stop AI trainingBlocking it does not stop training, because Baidu Bookmark is a search engine crawler. Block the operator's training crawler instead.
You run an online shopAllow it unless it is overloading your servers.
Your server is under load from botsRate-limit before blocking. It is rated safe in our database.

Check Baidu Bookmark on your own site

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

Common mistakes with Baidu Bookmark

The errors we see most often with Baidu Bookmark in the files and firewalls we test:

  1. Blocking Baidu Bookmark to save bandwidth and then wondering why pages drop out of that search engine. Use crawl-rate settings or caching first.
  2. Writing a User-agent: Baiduspider-favo group to add one rule for Baidu Bookmark and accidentally dropping every rule it used to follow under User-agent: *.
  3. Disallowing CSS and JavaScript folders, which can stop Baidu Bookmark rendering your pages properly.

All three hide inside a file that looks correct, so check Baidu Bookmark from outside after every change.

Spotting Baidu Bookmark in your logs

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

Check the requests are genuine

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

  • Baiduspider-favo: we hold no published IP list, so use reverse DNS where the operator documents a hostname and treat an unverifiable Baidu Bookmark request with caution.
