Frequently Asked Questions
Should I Block contentking?
Consider blocking contentking only if you do not want your pages included in SEO databases. It does not influence how search engines rank you, and blocking it will not hide backlinks to your site because those are discovered on the linking sites. For context, 7% of the top websites we track currently have robots.txt rules for contentking.
Does contentking Follow Robots.txt Rules?
Yes. contentking is expected to follow robots.txt rules, 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 contentking respects it.
Does contentking Access Private Content?
No. contentking can reach only public pages, and authentication prevents it from accessing private content.
How Can I Tell if contentking Is Visiting My Website?
Agent Analytics tracks contentking visits in real time. You can also check your server logs for requests whose user-agent string contains "contentking". Look for comprehensive site crawls that follow internal links. Because contentking does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is contentking Visiting My Website?
Your domain appears in the ranking, backlink, or competitor data maintained by contentking's operator. A customer may be tracking your site, one of your competitors, or a backlink that connects another site to yours.
