Frequently Asked Questions
What does the Robots.txt Checker actually check?
It fetches your robots.txt file, validates the syntax, and reviews every rule. You get a report showing blocked paths, misused directives, missing sitemap references, and recommendations to fix each issue.
Is the Robots.txt Checker free to use?
Yes. Create a free Brainito account and you can run robots.txt checks whenever you need them, along with the rest of Brainito's SEO tools. No credit card is required.
Can a robots.txt file really hurt my SEO?
Yes. A single Disallow rule in the wrong place can hide entire sections of your site from Google. Regular checks catch accidental blocks after site updates, migrations, or CMS changes before rankings drop.
