How to Generate a robots.txt File Step by Step
- Specify your rules. Set the rules you want, such as which parts of your site crawlers may or may not access, and for which crawlers the rules apply.
- Add any other directives. Include other directives you want, such as pointing to your sitemap, to give crawlers the guidance you intend.
- Generate the robots.txt. The tool produces a correctly formatted robots.txt file with the syntax matching your specified rules.
- Review the file. Check the generated robots.txt to confirm the rules are as you intend, since they control how crawlers treat your site.
- Place it on your site. Put the robots.txt file in the correct location on your site, typically the root, so crawlers find and follow it.
What robots.txt Is and What It Does
A robots.txt file is a file placed on a website that tells search engine crawlers how they should crawl the site, such as which parts they may or may not access. It sits at a standard location, typically the root of the site, where crawlers look for it. Through directives, it guides crawler behaviour, letting site owners control which areas of their site are crawled.
The file works through directives that specify rules for crawlers. You can indicate which crawlers the rules apply to, and which parts of the site they should or should not access, and include other directives such as pointing to the site's sitemap. Crawlers that respect robots.txt read these rules and behave accordingly, so the file is a way to communicate your crawling preferences to search engines.
The syntax of robots.txt, while not complex, must be correct for the rules to work as intended, and it is easy to make mistakes writing it by hand. A misplaced or misformatted directive can fail to have the intended effect, or unintentionally block or allow the wrong things. A generator produces correct syntax from your specified rules, reducing the risk of errors that could misconfigure how crawlers treat your site.
robots.txt generators are used by website owners and those managing sites who want to control crawler access. Because the file influences how search engines crawl a site, getting it right matters for SEO and for controlling what is crawled. A generator makes creating a correct robots.txt straightforward, letting you specify your rules and get properly formatted syntax, rather than risking errors writing the file manually.

| Aspect | Using a generator | Writing by hand |
|---|---|---|
| Syntax | Correct from your rules | Easy to get wrong |
| Errors | Reduced | More likely |

What is a robots.txt file?
A robots.txt file is a file placed on a website that tells search engine crawlers how they should crawl the site, such as which parts they may or may not access. It sits at a standard location, typically the root of the site, where crawlers look for it. Through directives, it guides crawler behaviour, letting site owners control which areas of their site are crawled. Crawlers that respect robots.txt read its rules and behave accordingly. So robots.txt is a way to communicate your crawling preferences to search engines, controlling what is crawled, which matters for SEO and for managing access to parts of your site.
What does robots.txt do?
robots.txt works through directives that specify rules for search engine crawlers. You can indicate which crawlers the rules apply to, which parts of the site they should or should not access, and include other directives such as pointing to the site's sitemap. Crawlers that respect robots.txt read these rules and behave accordingly, so the file lets you guide how search engines crawl your site, controlling which areas are crawled and helping crawlers find your content via the sitemap. It is a way to communicate your crawling preferences, influencing how your site is crawled, which is relevant for SEO and for keeping crawlers out of certain areas.
Why use a generator instead of writing it by hand?
Because although robots.txt syntax is not complex, it must be correct for the rules to work as intended, and it is easy to make mistakes writing it by hand. A misplaced or misformatted directive can fail to have the intended effect, or unintentionally block or allow the wrong things, which could harm your SEO or expose areas you meant to keep crawlers from. A generator produces correct syntax from your specified rules, reducing the risk of these errors. So using a generator makes creating a correct robots.txt straightforward, letting you specify your rules and get properly formatted syntax rather than risking misconfiguration from manual writing.
Where do I put the robots.txt file?
You place the robots.txt file at the standard location where crawlers look for it, which is typically the root of your site. Crawlers check this standard location for the file, so it must be there for them to find and read your rules. If you place it elsewhere, crawlers will not find it, and your directives will have no effect. So after generating and reviewing your robots.txt, put it in the correct location, typically the site root, ensuring crawlers can find and follow it. Correct placement is essential, since even a perfectly written robots.txt has no effect if crawlers cannot find it at the expected location.
Can robots.txt block content from search engines?
robots.txt can guide crawlers that respect it away from certain parts of your site, indicating areas they should not access. However, it is important to understand that robots.txt is a guideline for compliant crawlers, not a strict enforcement or security mechanism. Crawlers that respect it will follow its rules, but it does not physically prevent access. So while you can use robots.txt to indicate that crawlers should not crawl certain areas, you should not rely on it to secure or hide sensitive content, since it only communicates preferences. For actually protecting content, use proper security methods, reserving robots.txt for guiding the crawling behaviour of compliant search engine crawlers.
What is a common robots.txt mistake?
A common and serious mistake is accidentally blocking important content, where a rule that is too broad or misformatted prevents crawlers from accessing parts of your site you actually want crawled, which can harm your SEO. Because robots.txt controls crawler access, an overly broad or incorrect rule can have a big unintended effect. This is why being careful and specific with your rules, and reviewing the generated file before using it, is important, to confirm you block only what you intend. Using a generator for correct syntax and checking the file helps avoid this mistake, ensuring your robots.txt guides crawlers as you want without inadvertently blocking important content.
Is the robots.txt generator free?
Yes, it is completely free with no account and no usage limit. You can generate as many robots.txt files as you like, as often as you like, at no cost. It runs in your browser on any device, so there is nothing to download or install, and the correctly formatted robots.txt is ready to review and use once you specify your rules. Remember to review the file, place it in the correct location on your site, and understand that robots.txt guides compliant crawlers rather than enforcing access, using it to manage how search engines crawl your site.
