Frequently Asked Questions

Common questions about this tool answered.

What is a robots.txt file?
A robots.txt file is a text file at the root of a website that tells search engine crawlers which pages or sections they are allowed or not allowed to crawl. It is one of the first files search engines check when visiting your site.
Can a bad robots.txt hurt my SEO?
Yes. A misconfigured robots.txt can accidentally block search engines from crawling important pages, CSS files, or JavaScript resources, which can prevent pages from being indexed or cause them to render incorrectly in search results.
Should I block /admin or /login pages in robots.txt?
Robots.txt is not a security mechanism since it only suggests what not to crawl, it does not prevent access. For sensitive pages, use authentication and noindex meta tags instead. Blocking in robots.txt can actually draw attention to those URLs.
How do I add my sitemap to robots.txt?
Add a Sitemap directive at the bottom of your robots.txt file, like: Sitemap: https://example.com/sitemap.xml. This helps search engines discover and crawl your sitemap more efficiently.
How often should I review my robots.txt?
Review your robots.txt whenever you restructure your site, add new sections, or change your CMS. At minimum, audit it quarterly to catch accidental blocks that may have been introduced during development.
