What is a User Agent? How Do We Use User Agent Information for SEO?

What Is a User Agent? What are The Types?

A user agent is a software that has been developed to help a user better communicate with network servers. This software acts as a go-between for the user and the web server, almost like a real estate agent would be the mediator between a seller and a buyer. A user agent for browsers will collect the user’s information and instructions, process this data through to the network server and then receive the results which are then given back to the user. The data that will identify the user agent is transferred to the network server through the HTTP header, which will have different identification symbols that represent the user agent. One of the best examples of user agents is web browsers like Google Chrome or Internet Explorer! Different content management systems will use certain types of user agents so it is important to think about which one best suits your needs. 

What Is The Definition of User Agent Switcher?

The user agent switcher is an extension that will switch the user agent of the browser. So why use user agent switchers? These tools allow for access to restricted pages that might be restricted on the current browser that you are using. This extension will be installed on your toolbar allowing you to switch between the user agents that you are using when needed. If you are trying to gain access to a website that is restricted by your current user agent, you can go to the toolbar and switch to a different one and then test to see if you have access. You will know whether the switch has worked if you do not see HTTP status codes. 

What Is a User Agent List?

As different types of software are used across a variety of different devices, user agent lists have been developed to determine which devices and software go best with certain user agents. As different kinds of mobile devices use different user agents, having this information is important when it comes to understanding which user agents are best for certain devices and types of software. 

How To Process HTTP Requests and Server User Agent Information?

A user agent string will be used by the server as a way for HTTP requests to recognise the client and the different features that the client is able to process. If a certain format of the information will not be able to be read by the client, the server will send the data in a different format, one that can be read by the user agent and can therefore be seen by the client. This is extremely beneficial when it comes to websites being mobile-friendly as the server will send a certain version of data that is compatible with the specific user agent. When using a mobile device to get information, this would mean sending mobile-friendly data that can be read by the client using the device. 

How To Use User Agent Information for SEO?

How content appears in HTTP requests is important as this affects what the client will be viewing. This is vital when it comes to bots, which are responsible for crawling websites, and when it comes to using mobile-friendly versions of a website. When the server is able to determine the capabilities of browsers and devices, it can ensure that the content being displayed is projected correctly to the client, with the best quality of the content being displayed. When it comes to SEO, how your content is displayed and ensuring that those who are visiting your website are viewing it correctly is extremely important and can help you to rank higher on search engines. Using different user agents for SEO is important and understanding this topic is vital for complying with SEO tactics. 

How To Change Google Chrome User Agent?

As you may want to change certain user agents to better access certain web pages or features on a website, it is important to understand how to change your user agent. You will need to install a user agent switcher extension in order to do this and then change to different user agents as you need better access to certain features. 

User Agent Token

User agent tokens provide web servers with vital information to ensure that they can react appropriately when certain data is provided. These tokens exist within user agent strings and there are a variety of different types of tokens that exist. Version tokens are an example of the kinds of tokens that exist and these will display the version of the browser. 

What Are The Examples of Web Browser Bots and their User Agent Information?

Search engines use bots to scan through websites and they would therefore need their own versions of user agents, these are referred to as user agent strings. User-agent strings have a different syntax, one that is unique to the bots. This is to ensure that HTTP requests that are sent by these bots can be interpreted by the server and associated as requests by the bots and not clients. 

What Is The Importance of User Agents?

The importance of user agents should never be underestimated. User agents initiate a process called content negotiation whereby the HTTP requests can provide you with a different version of the same URL. Browsers with certain capabilities and plugins will best support certain versions of the content and this ensures that when the data is displayed to clients, it is in the best possible quality, with all information correctly displayed. A perfect example of how this works and can benefit the user is by looking at images. Images come in a variety of different formats and having a user agent that is able to correctly read a variety of different formats and displays will ensure that you receive all the possible information. If a user agent is not able to correctly interpret certain formats, the server will use a different format that the browser is capable of displaying.
