What is Baidu Image Search?

Baidu Image Search 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 Image Search can increase your visibility in AI-powered search results, which is why most sites choose to permit it.

Allowing Baidu Image Search can increase your visibility in AI-powered search results, which is why most sites choose to permit it.
Baidu Image Search uses the user-agent token Baiduspider-image. You can control it via robots.txt, meta tags (noai), or the emerging llms.txt standard. Robots.txt is voluntary; for hard enforcement, combine it with server-level IP blocking.

What happens if you block Baidu Image Search?

🔶 AI Visibility Trade-off - Blocking Baidu Image Search 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.
Generally safe to allow; provides legitimate crawling value.

Baidu Image Search in context

Baidu Image Search 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 critical. So Baidu Image Search is both well behaved and costly to lose: the strongest case for allowing it. How we rate safety and impact.

How site owners treat Baidu Image Search

Our robots.txt study of the Tranco top 10,000 did not track Baiduspider-image as a named token, so we do not publish an adoption figure for it.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 Image Search's operator does not clearly document how it treats robots.txt. Write the Baidu Image Search rule anyway, then confirm in your logs that its requests stop.

Baidu crawlers and close alternatives

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

  • Baiduspider-image: 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-favo: Baidu Bookmark, 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 Image Search the same answer as its siblings, stack User-agent: Baiduspider-image with their lines above one set of rules; to treat Baidu Image Search 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 Image Search is usually a decision about the whole group, so check how your file treats these too.

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

Which rule Baidu Image Search actually follows

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

User-agent: *
Disallow: /private/

User-agent: Baiduspider-image
Disallow: /drafts/
  1. Find the group. Baidu Image Search looks for a group naming Baiduspider-image. 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 Image Search, 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 Image Search if the file also has a User-agent: Baiduspider-image group?

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

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

Often, yes. Baidu Image Search 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-image the same as User-agent: Baiduspider-image?

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

Should you allow Baidu Image Search? Decide by situation

Recommended setting for Baidu Image Search 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 Image Search 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 Image Search on your own site

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

Common mistakes with Baidu Image Search

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

  1. Blocking Baidu Image Search 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-image group to add one rule for Baidu Image Search and accidentally dropping every rule it used to follow under User-agent: *.
  3. Disallowing CSS and JavaScript folders, which can stop Baidu Image Search rendering your pages properly.

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

Spotting Baidu Image Search in your logs

robots.txt says what Baidu Image Search 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-image" /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-image" /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 Image Search user-agent, so confirm the source before acting on a match:

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