What is DuckDuckBot?

Search Engine Crawler bot

What DuckDuckBot means for your site

DuckDuckBot is how your pages get discovered and ranked in web search results. Regular crawling means your content is being indexed and updated. Crawl frequency often reflects how search engines perceive your site's authority and freshness. A drop in crawling can signal technical problems, while consistent activity indicates a healthy site.

What should you do?

  • Allow DuckDuckBot full access to your site
  • Check robots.txt to ensure important pages are not blocked
  • Monitor crawl frequency trends in BotSights
  • Investigate if crawl activity drops unexpectedly
  • Ensure your sitemap is accessible and up-to-date

BotSights tracks every DuckDuckBot visit in real time, including which pages it crawls, how often, and from where.

How to identify DuckDuckBot

DuckDuckBot uses the user-agent "DuckDuckBot" and robots.txt compliance unconfirmed. Verify by checking the source IP against published ranges.

How to block DuckDuckBot

Three robots.txt options below. Pick the one that matches your goal. Each snippet lists every known DuckDuckBot user-agent pattern so the rules apply regardless of which one the bot announces. Compliance with robots.txt is unconfirmed for DuckDuckBot, so verify with crawl logs after deploying.

Edit robots.txt with care

A single misplaced line can de-index your entire site. Common mistake: pasting User-agent: * followed by Disallow: / blocks every bot, not just DuckDuckBot, including Googlebot. Always paste the snippet between existing rules (not over them), keep the User-agent line scoped to DuckDuckBot's patterns, and verify with Google's robots.txt tester before deploying. If you are not sure, ask a developer first.

Option 1: Block all access

Tells DuckDuckBot not to crawl any URL on your site. Use this when you want the bot completely off your content.

User-agent: DuckDuckBot
User-agent: duckduckbot
Disallow: /

Option 2: Block specific paths only

Keep public content crawlable but exclude sensitive or non-public sections. Add one Disallow: line per path. Replace the example paths with your own.

User-agent: DuckDuckBot
User-agent: duckduckbot
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/

Option 3: Slow down with a crawl delay

Crawl-delay is a voluntary directive that asks the bot to wait the given number of seconds between requests. Useful when DuckDuckBot is hammering your origin and slowing the site down for real visitors, but you do not want to block it outright. The value is in seconds, so 10 means at most one request every ten seconds. Not all bots honour this directive (Googlebot ignores it; Bingbot, Yandex, and many AI crawlers do respect it).

User-agent: DuckDuckBot
User-agent: duckduckbot
Crawl-delay: 10

Frequently Asked Questions

What is the User-Agent for DuckDuckBot?

DuckDuckBot identifies itself with the User-Agent string "DuckDuckBot" (alternate forms: duckduckbot). Use this in robots.txt rules and server-side filtering.

Should I block DuckDuckBot?

No. Blocking DuckDuckBot removes your pages from this search results and directly hurts your organic traffic. The only legitimate use case for blocking is on staging or development environments where you do not want indexing.

Should I block DuckDuckBot on my staging or dev site?

Yes — staging environments should not be indexed. Use robots.txt with "User-agent: DuckDuckBot / Disallow: /" or apply HTTP basic auth. Better: use a noindex meta tag plus a different hostname (staging.example.com) so production is unaffected.

Why has DuckDuckBot stopped visiting my site?

Common causes: robots.txt misconfiguration (accidental Disallow), server errors (5xx responses cause crawl-rate to drop), slow page load, soft 404s, or natural crawl budget adjustment. Check Search Console (or equivalent) for crawl errors first.

How does DuckDuckBot decide which pages to crawl?

DuckDuckBot prioritizes based on perceived page importance (links, freshness, content quality), site authority, and crawl budget. Submit a sitemap and ensure your most important pages are reachable from the homepage in 2-3 clicks for best coverage.

How can I tell if DuckDuckBot traffic is real and not spoofed?

User-Agent strings can be faked by scrapers pretending to be DuckDuckBot. Verify by checking the source IP against the operator's published ranges. BotSights flags spoofed traffic automatically and shows a verified badge per visit.

Does DuckDuckBot respect Crawl-delay?

Behavior varies. Set Crawl-delay in robots.txt and monitor whether crawl rate drops.
