Robots.txt Generator is a handy tool to generate a Robots.txt file in order to direct Google and other search engines that which page should be indexed by the crawlers and which page should be excluded and not be indexed. Creating Robots.txt is not a big deal, it's so easy and simple to generate the file.
Robots.txt is a text file that is created by webmasters to tell or instruct the search engine's crawlers how to crawl webpages on their website. The file instructs the robots which page should be crawled and which shouldn't be.
Actually, this file is part of Robots Exclusion Protocol (REP), it's the web standard that regulates the robot's crawling function and tells them how to crawl the website, and which page should be index. The crawl instructions are specified by the terms such as "disallowing" and "allowing".
User-Agent: [user-agent name]
Disallow:[URL string not to be crawled]
Crawl-Delay: This directive is very important and is used to prevent the crawlers from overloading the host. It's treated differently by different search engine bots. For Bing, it's a time interval in which the bot will visit the site. And for Google, you can control the visits of the bots by using Search Console.
User-Agents: This indicates the name of a specific crawler such as Googlebot for Google, baiduspider for Baidu, bingbot for Bing, and * for all web crawlers.
Allowing: Allowing means that a specific URL is allowed to be crawled by bots. You can add as many URLs as you want.
Disallowing: Disallowing means that a specific page or URL is not allowed to be crawled by bots. Add many URLs which you don't want to be crawled and indexed.
A sitemap is a structure or blueprint of the website that the Search Engine's robots crawl and index all the website (all pages and posts) whereas robot.txt instruct crawlers which page to crawl and which to not crawl. A sitemap is mandatory in order to index your site whereas robots.txt is not necessary, you can run a site without robot.txt but it's highly recommended that you generate robot.txt.
In order to use this tool, follow the steps below:
Enter all detail that is being asked such as Crawl-Delay, Sitemap, and other information.
Once you fill in all the fields, now click on the "Create Robots.txt" button or hit enter.
Wait for few seconds and you'll get the result.
