User Agent

Categories: U, SEO Glossary

User Agent refers to a software application or computing device that acts as an intermediary between the user and web servers. Its primary function is to facilitate communication by requesting content from servers, which then respond with data tailored to the user agent’s characteristics. This includes understanding and conveying the user’s preferences, as well as the specific capabilities of the device or application in use—such as supported technologies and display dimensions. By doing so, user agents ensure that users receive a web experience optimized for their particular setup.
