    Robots.txt is the first file looked by Google when it comes to website for crawling. In robots.txt you inform Google bots, which pages of your website need to be crawled and which pages should be avoided. Robots.txt can be substituted by Robots tag too.

    Robots.txt is a text (not html) file you put on your site to tell search robots which pages you would like them not to visit. Robots.txt is by no means mandatory for search engines but generally search engines obey what they are asked not to do.

    Robots.txt is a text file webmasters create to instruct web robots (typically search engine robots) how to crawl pages on their website. The robots.txt file is part of the the robots exclusion protocol (REP), a group of web standards that regulate how robots crawl the web, access and index content, and serve that content up to users. The REP also includes directives like [COLOR=#0077b3]meta robots[/COLOR], as well as page-, subdirectory-, or site-wide instructions for how search engines should treat links (such as “follow” or “nofollow”).
    In practice, [COLOR=#0077b3]robots.txt files indicate[/COLOR] whether certain user agents (web-crawling software) can or cannot crawl parts of a website. These crawl instructions are specified by “disallowing” or “allowing” the behavior of certain (or all) user agents.
    Basic format:

    User-agent: [user-agent name]
    Disallow: [URL string not to be crawled]Together, these two lines are considered a [COLOR=#0077b3]complete robots.txt file[/COLOR] — though one robots file can contain multiple lines of user agents and directives (i.e., disallows, allows, crawl-delays, etc.).
    Within a robots.txt file, each set of user-agent directives appear as a discrete set, separated by a line break:
    In a robots.txt file with multiple user-agent directives, each disallow or allow rule only applies to the useragent(s) specified in that particular line break-separated set. If the file contains a rule that [COLOR=#0077b3]applies to more than one user-agent[/COLOR], a crawler will only pay attention to (and follow the directives in) the most specific group of instructions.
    Here’s an example:
    Msnbot, discobot, and Slurp are all called out specifically, so those user-agents will only pay attention to the directives in their sections of the robots.txt file. All other user-agents will follow the directives in the user-agent: * group.
    Example robots.txt:

    Here are a few examples of robots.txt in action for a [COLOR=#0077b3]www.example.com[/COLOR] site:
    Robots.txt file URL: [COLOR=#0077b3]www.example.com/robots.txt[/COLOR]

    Blocking all web crawlers from all content

    User-agent: *
    Disallow: /Using this syntax in a robots.txt file would tell all web crawlers not to crawl any pages on [COLOR=#0077b3]www.example.com[/COLOR], including the homepage.
    Allowing all web crawlers access to all content

    User-agent: *
    Disallow: Using this syntax in a robots.txt file tells web crawlers to crawl all pages on [COLOR=#0077b3]www.example.com[/COLOR], including the homepage.
    Blocking a specific web crawler from a specific folder

    User-agent: Googlebot
    Disallow: /example-subfolder/This syntax tells only Google’s crawler (user-agent name Googlebot) not to crawl any pages that contain the URL string www.example.com/example-subfolder/.
    Blocking a specific web crawler from a specific web page

    User-agent: Bingbot
    Disallow: /example-subfolder/blocked-page.htmlThis syntax tells only Bing’s crawler (user-agent name Bing) to avoid crawling the specific page at www.example.com/example-subfolder/blocked-page.
    How does robots.txt work?

    Search engines have two main jobs:

    1. Crawling the web to discover content;
    2. Indexing that content so that it can be served up to searchers who are looking for information.

    To crawl sites, search engines follow links to get from one site to another — ultimately, crawling across many billions of links and websites. This crawling behavior is sometimes known as “spidering.”
    After arriving at a website but before spidering it, the search crawler will look for a robots.txt file. If it finds one, the crawler will read that file first before continuing through the page. Because the robots.txt file contains information about how the search engine should crawl, the information found there will instruct further crawler action on this particular site. If the robots.txt file does not contain any directives that disallow a user-agent’s activity (or if the site doesn’t have a robots.txt file), it will proceed to crawl other information on the site.
    Other quick robots.txt must-knows:

    (discussed in more detail below)

    • In order to be found, a robots.txt file must be placed in a website’s top-level directory.
    • Robots.txt is case sensitive: the file must be named “robots.txt” (not Robots.txt, robots.TXT, or otherwise).
    • Some user agents (robots) may choose to ignore your robots.txt file. This is especially common with more nefarious crawlers like malware robots or email address scrapers.
    • The /robots.txt file is a publicly available: just add /robots.txt to the end of any root domain to see that website’s directives (if that site has a robots.txt file!). This means that anyone can see what pages you do or don’t want to be crawled, so don’t use them to hide private user information.
    • Each subdomain on a root domain uses separate robots.txt files. This means that both blog.example.com and example.com should have their own robots.txt files (at blog.example.com/robots.txt and example.com/robots.txt).
    • It’s generally a best practice to indicate the location of any [COLOR=#0077b3]sitemaps[/COLOR] associated with this domain at the bottom of the robots.txt file. Here’s an example:

    Technical robots.txt syntax

    Robots.txt syntax can be thought of as the “language” of robots.txt files. There are five common terms you’re likely come across in a robots file. They include:

    • User-agent: The specific web crawler to which you’re giving crawl instructions (usually a search engine). A list of most user agents can be found [COLOR=#0077b3]here.[/COLOR]
    • Disallow: The command used to tell a user-agent not to crawl particular URL. Only one "Disallow:" line is allowed for each URL.
    • Allow[COLOR=#0077b3] (Only applicable for Googlebot): The command to tell Googlebot it can access a page or subfolder even though its parent page or subfolder may be disallowed.[/COLOR]
    • Crawl-delay: How many seconds a crawler should wait before loading and crawling page content. Note that Googlebot does not acknowledge this command, but [COLOR=#0077b3]crawl rate can be set in Google Search Console[/COLOR].
    • Sitemap: Used to call out the location of any XML sitemap(s) associated with this URL. Note this command [COLOR=#0077b3]is only supported[/COLOR] by Google, Ask, Bing, and Yahoo.

    Pattern-matching

    When it comes to the actual URLs to block or allow, robots.txt files can get fairly complex as they allow the use of pattern-matching to cover a range of possible URL options. Google and Bing both honor two [COLOR=#0077b3]regular expressions[/COLOR] that can be used to identify pages or subfolders that an SEO wants excluded. These two characters are the asterisk (*) and the dollar sign ($).

    • * is a wildcard that represents any sequence of characters
    • $ matches the end of the URL
