Frequently Asked Questions
Should I Block DuckDuckBot?
No, unless you want to remove your pages from that search engine. DuckDuckBot supplies its index, so blocking it can eliminate your visibility and organic traffic there. Nearly every website should allow this category. For context, 4% of the top websites we track currently have robots.txt rules for DuckDuckBot.
Does DuckDuckBot Follow Robots.txt Rules?
Yes. DuckDuckBot is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether DuckDuckBot respects it.
Does DuckDuckBot Access Private Content?
No special access. DuckDuckBot can reach only content available to anonymous visitors and does not sign in. Make sure sensitive content is not public by mistake.
Why Is DuckDuckBot Visiting My Website?
DuckDuckBot is adding new or changed pages to its search index. It may have discovered your site through links, a sitemap, or direct submission.
How Can I Tell if DuckDuckBot Is Visiting My Website?
Agent Analytics tracks visits from DuckDuckBot and every other known AI agent, crawler, and scraper, then authenticates each visit using DuckDuckBot's published verification method. You can also check your server logs for requests whose user-agent string contains "DuckDuckBot". Look for recurring passes that revisit changed pages and discover new ones. A matching log entry alone is not proof because any bot can claim to be DuckDuckBot.
