The user-agent string is bundled into the user-agent header in an HTTP web request.<\/p>\n<p>Take, a standard Google Chrome browser running on a Windows Operating System will send the below string as its user agent string.<\/p>\n<pre>Mozilla\/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit\/537.36 (KHTML, like Gecko) Chrome\/87.0.4280.88 Safari\/537.36<\/pre>\n<p>On iPhone, Chrome identifies itself in the string below.<\/p>\n<pre>Mozilla\/5.0 (iPhone; CPU iPhone OS 14_2 like Mac OS X) AppleWebKit\/605.1.15 (KHTML, like Gecko) CriOS\/87.0.4280.77 Mobile\/15E148 Safari\/604.1<\/pre>\n<p>Every other browser, web bot, and other client application has its own string its use in identifying itself. Looking at the strings above, you can see that it carries the name of the browser, its OS and platform, as well as versions, among others.<\/p>\n<p>One thing you need to take note of is that while there is a standard in naming, there is no compulsion in following the standard, and as such, some user agent strings can have just the name of the application or use an arbitrary or fake name. Some bot developers go as far as using the user agent of popular browsers in others to hide their activities.<\/p>\n<pre><a href=\"https:\/\/royadata.io\/blog\/bad-bot\/\">Bad Bot 101: What is it & How to Detect and Block Bad Bots?<\/a><\/pre>\n<hr\/>\n<h2 id=\"uses-of-user-agents\" class=\"ftwp-heading\" style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"Uses_of_User_Agents\"><\/span><strong>Uses of User Agents<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><picture class=\"aligncenter wp-image-7547 perfmatters-lazy\" loading=\"lazy\"><source type=\"image\/webp\" data-srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents.jpg.webp 1667w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-300x200.jpg.webp 300w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-1024x682.jpg.webp 1024w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-768x512.jpg.webp 768w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-1536x1024.jpg.webp 1536w\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%201000%20666'%3E%3C\/svg%3E\" data-sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><img decoding=\"async\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%201000%20666'%3E%3C\/svg%3E\" alt=\"Uses of User Agents\" width=\"1000\" height=\"666\" data-src=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents.jpg\" data-srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents.jpg 1667w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-300x200.jpg 300w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-1024x682.jpg 1024w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-768x512.jpg 768w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-1536x1024.jpg 1536w\" data-sizes=\"(max-width: 1000px) 100vw, 1000px\" loading=\"lazy\" \/>\n<\/picture>\n<noscript><picture class=\"aligncenter wp-image-7547\"><source type=\"image\/webp\" srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents.jpg.webp 1667w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-300x200.jpg.webp 300w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-1024x682.jpg.webp 1024w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-768x512.jpg.webp 768w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-1536x1024.jpg.webp 1536w\" sizes=\"(max-width: 1000px) 100vw, 1000px\"\/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents.jpg\" alt=\"Uses of User Agents\" width=\"1000\" height=\"666\" srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents.jpg 1667w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-300x200.jpg 300w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-1024x682.jpg 1024w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-768x512.jpg 768w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/Uses-of-User-Agents-1536x1024.jpg 1536w\" sizes=\"(max-width: 1000px) 100vw, 1000px\"\/>\n<\/picture>\n<\/noscript><\/p>\n<p>You might be wondering why would client software identify itself and what do web servers need that information for? It turns out that user agents have two major uses. These include content negotiation and access granting and blocks.<\/p>\n<ul>\n<li>\n<h3 id=\"content-negotiation\" class=\"ftwp-heading\"><span class=\"ez-toc-section\" id=\"Content_Negotiation\"><\/span><strong>Content Negotiation<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/li>\n<\/ul>\n<p>There are many variants of a web page served to devices based on their capabilities. Take, for instance, the structure of the Google search engine result page varies depending on the browser or platform you are using to access it. By looking at the user agent string, Google is able to serve you the best version for your browser and device.<\/p>\n<p>There are many other sites on the Internet that make use of user-agent for providing a better user experience. Without a user-agent, at best, you are served the generic version of a page, which may or may not render well on your browser. Bot developers use this to walk around avoiding JavaScript-rich site by using mobile browser agents that will get web servers to return a non-JavaScript heavy version of a page.<\/p>\n<ul>\n<li>\n<h3 id=\"access-negotiation-and-blocks\" class=\"ftwp-heading\"><span class=\"ez-toc-section\" id=\"Access_Negotiation_and_Blocks\"><\/span><strong>Access Negotiation and Blocks<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/li>\n<\/ul>\n<p>Perhaps, the most popular use of the user-agent string is to know whether a particular client software has the access right to access certain content or not. Web servers use the user-agent string in an HTTP request header to exclude crawlers, scrapers, and other bots from accessing their platform.<\/p>\n<p>Many of the popular websites on the Internet frown at bot traffic and, as such, will deny access to user-agents other than that of popular browsers. While they do this internally, they can provide web crawlers signals via the robots.txt file \u2013 and expect you to follow the directives in there. Generally, web servers only want to allow access to traffic originating from a user and tend to block traffic from automated sources, except there\u2019s a benefit for them.<\/p>\n<hr\/>\n<h2 id=\"the-robots-txt-file-and-user-agent\" class=\"ftwp-heading\" style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"The_Robotstxt_File_and_User-Agent\"><\/span><strong>The Robots.txt File and User-Agent<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The Robot Exclusion Standard, otherwise known as the robots.txt file, is a standard of communication used by web services to communicate specific directives to automation bots such as crawlers and scrapers. This standard informs a web bot whether it is allowed to access content on its pages or not. Some websites do not even have a robots.txt file. Others have and provide an extensive directive using it.<\/p>\n<p>With a robots.txt, you can give directives to specific bots or all bots. Some of the directives present in robots.txt files include granting and denying all bots or specific bots access, giving directives on crawl rate, and on certain pages you do not want bots to access.<\/p>\n<p><picture class=\"aligncenter wp-image-7544 perfmatters-lazy\" loading=\"lazy\"><source type=\"image\/webp\" data-srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent.jpg.webp 1193w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-300x150.jpg.webp 300w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-1024x513.jpg.webp 1024w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-768x385.jpg.webp 768w\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%201000%20501'%3E%3C\/svg%3E\" data-sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><img decoding=\"async\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%201000%20501'%3E%3C\/svg%3E\" alt=\"The Robots.txt File and User-Agent\" width=\"1000\" height=\"501\" data-src=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent.jpg\" data-srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent.jpg 1193w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-300x150.jpg 300w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-1024x513.jpg 1024w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-768x385.jpg 768w\" data-sizes=\"(max-width: 1000px) 100vw, 1000px\" loading=\"lazy\" \/>\n<\/picture>\n<noscript><picture class=\"aligncenter wp-image-7544\"><source type=\"image\/webp\" srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent.jpg.webp 1193w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-300x150.jpg.webp 300w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-1024x513.jpg.webp 1024w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-768x385.jpg.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\"\/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent.jpg\" alt=\"The Robots.txt File and User-Agent\" width=\"1000\" height=\"501\" srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent.jpg 1193w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-300x150.jpg 300w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-1024x513.jpg 1024w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/The-Robots.txt-File-and-User-Agent-768x385.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\"\/>\n<\/picture>\n<\/noscript><\/p>\n<p>Aside from the fact that not all web services permit web scraping automated access, some have lowered infrastructures and as such, provide directive on how their site should be accessed in an automated manner to avoid adversely affecting it server performance.

Google is taking a step to phase out user-agent strings in Chrome browsers, and other web browser vendors have shown interest.<\/p>\n<p>Currently, Google is unifying the user-agent string of Chrome browsers so that all you will know from the user agent string is that it is a Chrome browser running on a desktop or mobile.<\/p>\n<p><picture class=\"aligncenter wp-image-7552 size-full perfmatters-lazy\" loading=\"lazy\"><source type=\"image\/webp\" data-srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544.jpg.webp 680w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544-300x147.jpg.webp 300w\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%20680%20334'%3E%3C\/svg%3E\" data-sizes=\"(max-width: 680px) 100vw, 680px\" \/><img decoding=\"async\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%20680%20334'%3E%3C\/svg%3E\" alt=\"user agent Client Hint\" width=\"680\" height=\"334\" data-src=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544.jpg\" data-srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544.jpg 680w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544-300x147.jpg 300w\" data-sizes=\"(max-width: 680px) 100vw, 680px\" loading=\"lazy\" \/>\n<\/picture>\n<noscript><picture class=\"aligncenter wp-image-7552 size-full\"><source type=\"image\/webp\" srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544.jpg.webp 680w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544-300x147.jpg.webp 300w\" sizes=\"(max-width: 680px) 100vw, 680px\"\/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544.jpg\" alt=\"user agent Client Hint\" width=\"680\" height=\"334\" srcset=\"https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544.jpg 680w, https:\/\/royadata.io\/blog\/wp-content\/uploads\/2023\/10\/user-agent-Client-Hint-e1608862279544-300x147.jpg 300w\" sizes=\"(max-width: 680px) 100vw, 680px\"\/>\n<\/picture>\n<\/noscript><\/p>\n<p>From the above, you can see that the future of the user agent string is Client Hint. What Client Hint will do is that it queries web browsers to return certain information about itself without revealing too much information that can be used in tracking. Using the information provided, web servers can use the hint for content negotiation, which is the main use of the user agent string.<\/p>\n<pre style=\"text-align: center;\"><strong>Conclusion<\/strong><\/pre>\n<p>There is no doubt that the user agent string has its place in the area of content negotiation and the identification of client application for access right determination. However, they have been termed as messy and termed as a \u201cfingerprintable\u201d detail that helps throw privacy out through the window.<\/p>\n<p>For this reason, a better alternative is being searched as Client Hint is the likely candidate. For now, it is still in use, and you need to consider it in the scheme of things.<\/p>\n<hr\/>\n<ul>\n<li><a href=\"https:\/\/royadata.io\/blog\/proxies-for-scraping-google\/\">Proxies for Preventing Bans and Captchas When Scraping Google<\/a><\/li>\n<li><a href=\"https:\/\/royadata.io\/blog\/how-to-detect-if-an-ip-address-is-a-proxy\/\">5 Ways to Detect if an IP Address is a Proxy<\/a><\/li>\n<li><a href=\"https:\/\/royadata.io\/blog\/proxies-for-bypassing-blocked-search-engines\/\">Why Your Proxies Are Blocked by Search Engines<\/a><\/li>\n<li><strong><a href=\"https:\/\/royadata.io\/blog\/scrape-a-website-never-get-blacklisted\/\">How to Scrape a Website without getting Blocked!<\/a><\/strong><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Find out what your User Agent is revealing about you!
