What Is a Robots.txt Generator?
A robots.txt generator creates valid robots.txt rules from user inputs so beginners can generate crawler instructions without writing the file manually. It can help create allow rules, disallow rules, sitemap lines, and simple crawler groups for websites, blogs, stores, and SEO projects.
Where Should Robots.txt Be Placed?
Robots.txt should be uploaded to the root of the site host it
controls, such as https://example.com/robots.txt. It
