What Is My User Agent
Find your User Agent
While interacting with the browser, the user may encounter such a concept as the User agent. The technology with this name is used in all web browsers.
A user Agent is a client application used by browsers and other web applications to display information about themselves on the corresponding line.
What is a User Agent used for, and what does it consist of?
All browsers, mobile devices, and search robots contain User Agent. The line displays all the necessary information about your computer or phone, browser version, operating system, and robot.
You can also specify lines with the User-agent description in the file Robots.txt; they are essential for the correct operation of search robots on the site. Using strings, you can hide the data contained on the resource from all or certain search engines: a specific page or entire site, a particular type of file, personal data of users, and so on. So, using the User-agent, you can hide, for example, only images or open them for indexing exclusively.
You can prohibit scanning information by instructing all bots or the robot of a specific search engine that the User Agent recognizes.
The User-Agent description line contains the following information:
- Name and version of the browser.
- Operating system version.
- Software installed on the device you are using.
- The type of device that the user used to access the site.
You can change the User Agent to change the indexing parameters of the resource, hide information that should not show to unauthorized persons, and update the old browser so that you no longer receive notifications about the need to install another application.
The line contains different instructions for each browser and operating system of the device.
Types of User Agents
It is important to note that each type of device, whether a PC, laptop, smartphone, or tablet, can have its user agent, and then everything depends on the software used. The User-Agent is being identified:
Web browsers. This includes all browsers: Google Chrome, Yandex Browser, Opera, and others.
