What is a robots.txt file?
Robots.txt is a small text file located in the root directory of your website. It’s job is to tell search engine robots what content on your website what not to visit.
Why would I want to do this?
The main reason why you want to do this from an SEO standpoint is to avoid duplicate content issues. For example if you have a printer friendly page on your website you would not want this indexed because it would be competing with the main page.
