About Robots.txt Generator

Robots.txt is a text file located in the site’s root directory that specifies for search engines’ crawlers and spiders what website pages and files you want or don’t want them to visit. Usually, site owners strive to be noticed by search engines, but there are cases when it’s not needed: For instance, if you store sensitive data or you want to save bandwidth by not indexing excluding heavy pages with images.

A robots.txt file lives at the root of your website. So, for site YYY com, the robots.txt file lives at http:/www YYY com/robots.txt. A robots.txt file consists of one or more rules. Each rule blocks (or allows) access for a given crawler to a specified file path in that website.

Basic robots.txt examples:

Prevent the whole website from indexation by all crawlers:
User-agent: *
 Disallow: /

Allow all web crawlers to index the whole website:
User-agent: *

Prevent only several directories from indexation:
User-agent: *
Disallow: /script/

Prevent the website’s indexation by a specific web crawler:
User-agent: Bot1
Disallow: /
