How to use the DuckDuckBot simulator
-
Step 1
Enter a URL
Paste the full URL of any page on your website, such as a product page, a blog post, or the home page.
-
Step 2
Select the DuckDuckBot user agent
The tester sends the request with the DuckDuckBot user-agent string, so your server answers the way it answers a real DuckDuckBot visit.
-
Step 3
Run the crawl
The simulator requests the page as DuckDuckBot and follows redirects, the same way the crawler does.
-
Step 4
Inspect the HTML
Check the status code, redirects, response headers, raw HTML, word count, and Open Graph tags DuckDuckBot gets. If your main content is missing from the HTML, DuckDuckBot cannot read it.
What is DuckDuckBot?
DuckDuckBot is DuckDuckGo's web crawler that indexes content for their privacy-focused search engine. DuckDuckGo also has DuckAssistBot for their AI-powered DuckAssist feature. With growing privacy concerns, DuckDuckGo's user base continues to expand, making optimization worthwhile.
Why allow DuckDuckBot?
DuckDuckBot robots.txt configuration
