In web analytics, individuals use different devices to access a website, such as computers, smartphones, tablets, and smart TVs. Web analytics tools, such as Google Analytics, track and report on the devices used to access a website to analyze the behavior and preferences of website visitors.
Tracking the devices that access a website can help optimize the user experience and design: website owners and marketers can identify the devices that are most commonly used to access the website and optimize the layout and design of the website for those devices.
