User-agent string

What is a user-agent string

Browsers and web crawlers send a special identification, called the user-agent string, to the website they're accessing. This user-agent can be used to tailor the reply, for example: when the user-agent string makes it clear that the website is being accessed on a phone the mobile variant of the website may be returned. If the web server software keeps logs of all visitors to the website it usually also stores the user-agent string to allow identification of the different traffic.

Default user-agent string

By default, ContentKing sends this user-agent string when making requests:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36 (+

This may change in the future, so check this page regularly for updates.

Changing the user-agent string

You can configure which user-agent string ContentKing should use when monitoring your website in the Monitoring section of the Website Settings:

ContentKing user-agent list

You can pick a predefined user-agent string from the list or set a fully custom user-agent string if you have validated ownership of the website. You can validate ownership of the website by connecting Google Analytics or Google Search Console. More about website verification here
