What is DeepSeekBot?

The web crawler for DeepSeek, a Chinese AI lab known for high-performance open models. It is often opaque and aggressive.

The web crawler for DeepSeek, a Chinese AI lab known for high-performance open models. It is often opaque and aggressive. DeepSeekBot is an AI data-collection crawler operated by DeepSeek. It harvests web content to build or expand training datasets for large language models (LLMs). Unlike search crawlers, DeepSeekBot does NOT influence your page ranking in any search engine. The user-agent string DeepSeekBot can be safely blocked via robots.txt, meta tags (noai), or the emerging llms.txt standard without any SEO penalty. Robots.txt is voluntary; for hard enforcement, combine it with server-level IP blocking.

What happens if you block DeepSeekBot?

✅ **No SEO Impact** - Blocking DeepSeekBot does not affect your rankings in Google, Bing, or any other search engine. DeepSeekBot is an AI training crawler, not a search indexer. You can freely block it via User-agent: DeepSeekBot / Disallow: / without any SEO penalty. This is the recommended approach if you want to opt out of DeepSeek's LLM training datasets.
Block this bot - it provides no SEO benefit and wastes crawl budget.

How to block DeepSeekBot with robots.txt

<code>User-agent: DeepSeekBot</code> - Matching is case-insensitive. Robots.txt is fetched from the root of each subdomain separately. For aggressive bots, supplement with server-level blocking for guaranteed enforcement.

Block completely (robots.txt)
User-agent: DeepSeekBot Disallow: /
Allow all (robots.txt)
User-agent: DeepSeekBot Allow: /
Block private only (robots.txt)
User-agent: DeepSeekBot Disallow: /private/ Disallow: /api/ Disallow: /admin/ Allow: /
Nginx server block
# Nginx: Hard-block DeepSeekBot if ($http_user_agent ~* "DeepSeekBot") { return 403 "Bot blocked"; }
Apache .htaccess
# Apache: Hard-block DeepSeekBot SetEnvIfNoCase User-Agent "DeepSeekBot" bad_bot Order Allow,Deny Allow from all Deny from env=bad_bot
Meta robots tag
<meta name="robots" content="noindex, nofollow">
X-Robots-Tag header
X-Robots-Tag: noindex, nofollow

Is DeepSeekBot safe to allow?

🔴 **DeepSeekBot is classified as Aggressive.** This bot has been observed ignoring robots.txt directives, crawling at excessive rates that impact server performance, or collecting data in ways that violate standard web etiquette. **We strongly recommend blocking this bot** at both the robots.txt level AND server level (Nginx/Apache/Cloudflare WAF). A robots.txt block alone may be insufficient if the bot does not respect it.

What does DeepSeekBot do?

Understanding DeepSeekBot's purpose helps you decide whether to allow or block it.

  • Collects web content for AI model training
  • Gathers data to improve language understanding
  • Scrapes text, code, and other content for datasets
  • May be used for chatbot and AI assistant development
  • Typically does NOT affect search engine rankings

Frequently Asked Questions

What is the official user-agent string for DeepSeekBot?
The official user-agent string for DeepSeekBot is: DeepSeekBot. This is the exact string you must use in robots.txt, Nginx, Apache, or Cloudflare firewall rules to target this bot. User-agent matching in robots.txt is case-insensitive, but the string must be spelled correctly. You can verify that a request genuinely comes from DeepSeekBot by performing a reverse-DNS lookup on the source IP - legitimate bots resolve back to their operator's domain.

Will blocking DeepSeekBot hurt my SEO?
✅ **No SEO Impact** - Blocking DeepSeekBot does not affect your rankings in Google, Bing, or any other search engine. DeepSeekBot is an AI training crawler, not a search indexer. You can freely block it via User-agent: DeepSeekBot / Disallow: / without any SEO penalty. This is the recommended approach if you want to opt out of DeepSeek's LLM training datasets.
How do I block DeepSeekBot in robots.txt?
Add the following lines to your /robots.txt file: 
User-agent: DeepSeekBot
Disallow: /
This instructs DeepSeekBot not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders. To only block specific sections, replace / with the path (e.g., Disallow: /blog/). Note: robots.txt is publicly readable - any bot or human can inspect it at yourdomain.com/robots.txt.
Does DeepSeekBot respect robots.txt?
⚠️ DeepSeekBot may not always respect robots.txt. For guaranteed blocking, combine robots.txt with server-level rules (Nginx if/return 403, Apache SetEnvIf, or Cloudflare WAF).
How do I verify if DeepSeekBot is crawling my site?
Search your web server access logs for the string DeepSeekBot (case-insensitive grep: grep -i "DeepSeekBot" /var/log/nginx/access.log). You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants. For DeepSeekBot specifically, filter by user-agent in your log analysis tool (GoAccess, AWStats, etc.).
What is the crawl frequency of DeepSeekBot?
Crawl frequency data for DeepSeekBot is not publicly documented. Monitor your logs to understand actual visit patterns.
Can I block DeepSeekBot from specific pages only?
Yes. Instead of a global Disallow: / you can restrict DeepSeekBot to specific paths: 
User-agent: DeepSeekBot
Disallow: /private/
Disallow: /staging/
Allow: /
This allows DeepSeekBot everywhere except the listed paths. Path matching in robots.txt uses prefix matching - Disallow: /private/ blocks /private/page.html but NOT /public/private/.
Does blocking DeepSeekBot prevent AI training on my content?
Blocking DeepSeekBot via robots.txt signals to DeepSeek that your content should not be used for AI training. However, robots.txt is a **voluntary** protocol - there is no technical enforcement. For stronger protection: 1. Add <meta name="DeepSeekBot" content="noai, noimageai, noindex"> to your pages. 2. Add a llms.txt file at your domain root (emerging standard). 3. Use Cloudflare WAF or Nginx to return 403 for this user-agent. 4. Consider IP blocklists for DeepSeek's known crawler IP ranges.
Is there an alternative to robots.txt to opt out of DeepSeekBot?
Yes. Several additional opt-out mechanisms exist for AI crawlers: • **Meta tag**: <meta name="DeepSeekBot" content="noindex"> • **X-Robots-Tag HTTP header**: X-Robots-Tag: noai, noimageai • **llms.txt**: Add a /llms.txt file (similar to robots.txt but for LLMs) • **Server block**: Return 403 or 429 for this user-agent via WAF or Nginx Using multiple layers provides the strongest protection.
