About ContentKing

ContentKing is a cloud-based service that monitors websites from a digital marketing perspective. We monitor the websites for customers such as Netflix, Atlassian, Fedex and IBM and alert their digital marketing teams whenever a technical issue or content change is detected.

Monitoring bots check uptime, performance and page changes on behalf of a site owner or a third party. Allow the services you run yourself and exclude them from analytics so they do not inflate page views.

ContentKing user agent

ContentKing identifies itself with this user agent string:

  • (+https://whatis.contentkingapp.com)

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block ContentKing in robots.txt

We have not confirmed whether ContentKing follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Block ContentKing from the whole site

User-agent: contentking
Disallow: /

Block ContentKing from some folders

User-agent: contentking
Disallow: /private/
Disallow: /search

Allow ContentKing only on some folders

User-agent: contentking
Allow: /blog/
Disallow: /

Allow ContentKing and block other crawlers

User-agent: contentking
Allow: /

User-agent: *
Disallow: /

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: contentking group, ContentKing ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take contentking from ContentKing's user agent; check ContentKing's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. ContentKing may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that ContentKing follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send ContentKing's user agent, and a scraper using it is not bound by ContentKing's robots.txt policy. Only checking the source network tells a real ContentKing from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.

Frequently asked questions

What is ContentKing?

ContentKing is a bot in the monitoring and analytics bots category, operated by ContentKing. ContentKing is a cloud-based service that monitors websites from a digital marketing perspective. We monitor the websites for customers such as Netflix, Atlassian, Fedex and IBM and alert their digital marketing teams whenever a technical issue or content change is detected.

Does ContentKing respect robots.txt?

We have not confirmed whether ContentKing follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.

How do I block ContentKing?

Add "User-agent: contentking" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "contentking" at your WAF. In Transfon Security that is one User Agent block rule.

Is robots.txt enough to block ContentKing?

No. robots.txt is voluntary, so ContentKing may not follow it, and anyone can send ContentKing's user agent, so a fake ContentKing ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.

Should I block ContentKing?

Monitoring bots check uptime, performance and page changes on behalf of a site owner or a third party. Allow the services you run yourself and exclude them from analytics so they do not inflate page views.
