Frequently Asked Questions
What is a robots.txt generator?
A robots.txt generator is a tool that helps you create a robots.txt file with the correct directives for search engine crawlers. It provides a visual interface for setting allow/disallow rules without writing code manually.
Why do I need a robots.txt file?
A robots.txt file tells search engine crawlers which pages to crawl and which to skip. It helps manage crawl budget, prevent indexing of admin pages or duplicate content, and guide crawlers to your most important pages.
What's the difference between allow and disallow?
Allow directives tell crawlers they CAN access a path. Disallow directives tell crawlers they CANNOT access a path. Disallow takes precedence when both apply to the same URL.
How do I test my robots.txt file?
Use Google Search Console's robots.txt tester to verify your rules. You can also check the file by visiting yourdomain.com/robots.txt directly in a browser.
