Format and location You can use almost any text editor to create a robots.txt file. The text editor should be able to create standard ASCII or UTF-8 text files; don't use a word processor, because word processors often save files in a proprietary format and can add unexpected characters, such as curly quotes, which can cause problems for crawlers. Use the tool to write or edit robots.txt files for your site. This tool enables you to test the syntax and behavior against your site. Format and location rules:.
The file must be named robots.txt. Your site can have only one robots.txt file. The robots.txt file must be located at the root of the website host that it applies to. For instance, to control crawling on all URLs below the robots.txt file must be located at It cannot be placed in a subdirectory ( for example, at If you're unsure about how to access your website root, or need permissions to do so, contact your web hosting service provider. If you can't access your website root, use an alternative blocking method such as. A robots.txt file can apply to subdomains (for example, website.example.com/robots.txt) or on non-standard ports (for example, 8181/robots.txt).
Comments are any lines Syntax. robots.txt must be an ASCII or UTF-8 text file. No other characters are permitted. A robots.txt file consists of one or more rules. Each rule consists of multiple directives (instructions), one directive per line. A rule gives the following information:. Who the rule applies to (the user agent).

Which directories or files that agent can access, and/or. Which directories or files that agent cannot access. Rules are processed from top to bottom, and a user agent can match only one rule set, which is the first, most-specific rule that matches a given user agent.
The default assumption is that a user agent can crawl any page or directory not blocked by a Disallow: rule. Rules are case-sensitive. For instance, Disallow: /file.asp applies to but not The following directives are used in robots.txt files:. User-agent: Required, one or more per rule The name of a search engine robot (web crawler software) that the rule applies to. This is the first line for any rule. Most user-agent names are listed in the or in the. Supports the.

Disallow: /. Disallow: At least one or more Disallow or Allow entries per rule A directory or page, relative to the root domain, that should not be crawled by the user agent.

Must be a fully-qualified URL; Google doesn't assume or check http/https/www.non-www alternates. Sitemaps are a good way to indicate which content Google should crawl, as opposed to which content it can or cannot crawl. Example: Sitemap: Sitemap: Unknown keywords are ignored. Another example file A robots.txt file consists of one or more blocks of rules, each beginning with a User-agent line that specifies the target of the rules. Here is a file with two rules; inline comments explain each rule: # Block googlebot from example.com/directory1/.
And example.com/directory2/. # but allow access to directory2/subdirectory1/. # All other directories on the site are allowed by default.

Useful robots.txt rules Here are some common useful robots.txt rules: Rule Sample Disallow crawling of the entire website. Keep in mind that in some situations URLs from the website may still be indexed, even if they haven't been crawled. Note: this does not match the, which must be named explicitly. User-agent:.
Disallow: / Disallow crawling of a directory and its contents by following the directory name with a forward slash. Remember that you shouldn't use robots.txt to block access to private content: use proper authentication instead. URLs disallowed by the robots.txt file might still be indexed without being crawled, and the robots.txt file can be viewed by anyone, potentially disclosing the location of your private content.
A robots.txtfile is a file at the root of your site that indicates those parts of your site you don’t want accessed by search engine crawlers. The file uses the, which is a protocol with a small set of commands that can be used to indicate access to your site by section and by specific kinds of web crawlers (such as mobile crawlers vs desktop crawlers). What is robots.txt used for? Non-image files For non-image files (that is, web pages) robots.txt should only be used to control crawling traffic, typically because you don't want your server to be overwhelmed by Google's crawler or to waste crawl budget crawling unimportant or similar pages on your site. You should not use robots.txt as a means to hide your web pages from Google Search results. This is because other pages might point to your page, and your page could get indexed that way, avoiding the robots.txt file.
If you want to block your page from search results, use another method such as password protection. Image files robots.txt does prevent image files from appearing in Google search results. (However it does not prevent other pages or users from linking to your image.) Resource files You can use robots.txt to block resource files such as unimportant image, script, or style files, if you think that pages loaded without these resources will not be significantly affected by the loss. However, if the absence of these resources make the page harder to understand for Google's crawler, you should not block them, or else Google won't do a good job of analyzing your pages that depend on those resources. Understand the limitations of robots.txt Before you build your robots.txt, you should know the risks of this URL blocking method.
At times, you might want to consider other mechanisms to ensure your URLs are not findable on the web. Robots.txt instructions are directives only The instructions in robots.txt files cannot enforce crawler behavior to your site; instead, these instructions act as directives to the crawlers accessing your site.
While Googlebot and other respectable web crawlers obey the instructions in a robots.txt file, other crawlers might not. Therefore, if you want to keep information secure from web crawlers, it’s better to use other blocking methods, such as.
Different crawlers interpret syntax differently Although respectable web crawlers follow the directives in a robots.txt file, each crawler might interpret the directives differently. You should know the proper syntax for addressing different web crawlers as some might not understand certain instructions. A robotted page can still be indexed if linked to from from other sites While Google won't crawl or index the content blocked by robots.txt, we might still find and index a disallowed URL if it is linked from other places on the web.
As a result, the URL address and, potentially, other publicly available information such as anchor text in links to the page can still appear in Google search results. To properly prevent your URL from appearing in Google Search results, you should or (or remove the page entirely).
