Robots.txt Guide

[megri]

The robots.txt is a very simple text file that is placed on your root directory. An example would be yourdomain.com/robots.txt. This file tells search engine and other robots which areas of your site they are allowed to visit and index.

At it's most simple, a robots.txt file while allow every thing to index looks like this:

User-agent: *
Disallow:

If you disallow to all bots

User-agent: *
Disallow: /

Allows only major search engines and known friendly spiders

To remove your site from Google only and prevent just Googlebot from crawling your site in the future, place the following robots.txt file in your server root:

User-agent: Googlebot
Disallow: / To remove all pages under a particular directory (for example, cgi-bin), you'd use the following robots.txt entry:

User-agent: Googlebot
Disallow: /cgi-bin

[megri]

To ask MSN Bot to visit after 10 days you can use below

User-agent: msnbot
Crawl-delay: 10

You can see the google robots.txt file here
