Device User Experience (UX)

Do you provide downloadable software for computers, smartphones, and tablets? Do you have a blog section for one or all 3 device types?

Customizing content according to a browser user agent is a quick way to push the right content to the right visitor without invading users’ privacy.

For a quick summary, a user agent is HTTP header information sent with your requests throughout the internet. It includes your operating system (OS), or the base OS for Unix distributions (for example, Ubuntu for Mint), browser name and version, preferred language, and more. This information allows websites to tailor content to different devices.

You can quickly view your current user agent by searching “user agent” in

The UserAgent Content Switcher WordPress plugin allows you to specify content for users on computers, smartphones, tablets, and older feature phones (Nokia brick phone for example).

Below we cover some possible uses of the UserAgent Content Switcher.
