Expected Behavior

contentking maps sites the way its customers' SEO tools need, following internal links to build a full picture of structure, content, and ranking signals. Expect thorough crawls rather than spot checks, with frequency rising when your site or your competitors are actively monitored in its tools.

Frequently Asked Questions

Should I Block contentking?

Only if you want your own pages and outbound links out of those tools. contentking collects the ranking and backlink data behind SEO tools, likely including ones you or your agency use, and it does not change how search engines rank you. Blocking it will not hide your backlink profile either, because backlinks are discovered on the sites that link to you. Almost none of the top websites we track have robots.txt rules for contentking right now.

Does contentking Respect Robots.txt?

Yes. contentking is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms contentking actually honors it.

Does contentking Access Private Content?

Login walls stop it. contentking analyzes public pages for rankings, links, and site structure.

Why Is contentking Visiting My Website?

Your domain shows up in the ranking, backlink, and competitor data contentking's operator sells. If anyone tracks your site or your competitors in an SEO tool, contentking visits you.

How Can I Tell if contentking Is Visiting My Website?

Agent Analytics tracks contentking visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "contentking". Look for full site crawls that follow your internal links. Keep in mind that contentking doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
