Questions

What is a robots.txt file and why do I need one?
A robots.txt file tells search engine crawlers which pages or directories on your site they should or should not access. It is placed at the root of your domain and helps manage crawl budget, prevent indexing of private pages, and guide SEO strategy.
Can robots.txt block a page from appearing in Google search results?
Robots.txt can prevent crawling but does not guarantee removal from search results. If other sites link to a blocked page, Google may still index the URL without content. Use a noindex meta tag or X-Robots-Tag header for reliable deindexing.
Where do I place the robots.txt file on my server?
Place it at the root of your domain so it is accessible at https://yourdomain.com/robots.txt. Search engine crawlers always look for it at that exact URL.
Is robots.txt a security measure?
No. Robots.txt is a voluntary directive that well-behaved crawlers follow, but malicious bots can ignore it entirely. Do not rely on robots.txt to protect sensitive content; use authentication or access controls instead.
How do I allow all crawlers but block a specific directory?
Use User-agent: * with a Disallow rule for the directory you want blocked, such as Disallow: /admin/. The generator makes this easy with a visual rule builder.
