 +===== Definition =====
 +
 +The **robots.txt** is a text file stored on the website'​s server. It can be used to leave instructions for [[crawler|crawlers]] (e.g. which pages they should not visit or index). This way you can make sure certain pages won't be displayed in the search results.

 +===== Importance for SEO =====
 +
 +It is important to realize that the instructions in the robots.txt are rather suggestions than mandatory instructions. While most crawlers will follow these instructions,​ some might ignore them. Furthermore,​ even a backlink from another website could be enough to index a page, although you don't want that.
