Frequently Asked Questions

Where do I upload the `robots.txt` file?

The `robots.txt` file must be placed in the root directory of your website. For example, `https://www.yourwebsite.com/robots.txt`.

What's the difference between 'Allow' and 'Block'?

`Disallow: /` tells a bot it should not crawl any pages on the site. `Allow: /` explicitly permits a bot to crawl all pages. If no rule is specified for a bot, it is implicitly allowed.

Can I block bots from specific parts of my site?

This basic generator blocks access to the entire site. For more complex rules, like blocking specific folders (e.g., `Disallow: /private/`), you can manually edit the generated file before uploading it.

The `robots.txt` File: Your Website's Gatekeeper

The `robots.txt` file is a fundamental part of the Robots Exclusion Protocol (REP), a standard used by websites to communicate with web crawlers and other web robots. The file, which must be placed at the root of a domain, gives instructions about which parts of the website should not be processed or scanned by crawlers.

While originally designed for traditional search engines like Google, `robots.txt` has become the de facto standard for controlling access for a new wave of AI crawlers. These bots, operated by AI companies, collect vast amounts of text and data to train their models. By using a `robots.txt` file, you can signal your preferences about whether your content should be used for this purpose.

Key Directives in `robots.txt`

Our generator uses two main directives to create rules for AI bots:

  • User-agent: This directive specifies which crawler the rule applies to. For example, `User-agent: GPTBot` targets OpenAI's main training crawler. Each bot has a unique user-agent string.
  • Disallow: This directive tells the specified user-agent not to crawl the paths that follow. Our generator uses `Disallow: /` to block a bot from accessing the entire website.
  • Allow: While not part of the original standard, `Allow` is recognized by major crawlers like Google. It can be used to counteract a `Disallow` directive for a specific sub-path. Our generator uses `Allow: /` to explicitly permit access, which is the default behavior if no `Disallow` rule matches.

It's important to remember that `robots.txt` is a guideline, not an enforcement mechanism. Reputable companies will respect the rules you set, but malicious actors will likely ignore them.
