How do I use Robots.txt and the noindex meta tag?
Quick Answer: To create a Robots.txt file, you can use any text editor (such as Notepad). Make sure to save the file with UTF-8 encoding during the save file dialog. This file must also be named “robots.txt,” and your site can only have one such file. This file must also be located at the root of the website host you’re applying it to. To use a noindex tag for pages that you do not want to be included in search results, add “<meta name=”robots” content=”noindex”>” to the <head> section. Or, you can add the noindex tag using a X-Robots-Tag in the HTTP header: “X-Robots-Tag: noindex”.
