# Robots.Txt File for Beginners: The 5-Minute Primer

If you've never touched robots.txt file before, here's the version without the jargon.

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.

You don't need to understand everything about it on day one. Start with just this: never use robots.txt to try to keep a page out of the index — it only blocks crawling, not indexing; a blocked page with external links pointing to it can still show up in search results with no description.

The most common beginner mistake is skipping it entirely because it sounds technical. It usually isn't — robots.txt file is one of those things that looks intimidating from the outside and takes ten minutes once you actually sit down with it.

Once this feels comfortable, broken image links is a natural next thing to learn.

Robots.txt Generator is the fastest way to see it in action on a real page.
