**What is robots.txt file, in plain terms?**
robots.txt is one of the smallest files on your server and one of the easiest to get catastrophically wrong — a single misplaced Disallow: / has taken entire sites out of Google's index overnight.
**How often should this be checked?**
Regularly, not just once. Disallowing CSS/JS folders, which stops Google from rendering the page properly and can hurt how it's evaluated. Set a recurring reminder rather than trusting memory.
**What's the most common mistake here?**
Blocking /wp-admin/ or /cgi-bin/ style paths that don't exist on your platform, copied from a generic template without checking.
**Does this actually affect rankings, or is it just best practice?**
It's rarely a single ranking factor on its own, but it affects whether search engines and users can do what you actually need them to do — which shows up in rankings indirectly, often more than any one direct factor would.
**What's the fastest way to check this on an existing site?**
[Robots.txt Generator](../tools/robots-generator.html) — paste your URL in and it does the check directly, no setup.
