Structure of a Robots.txt File :

The structure of a robots.txt is pretty simple (and barely flexible) � it is an endless list of user agents and disallowed files and directories. Basically, the syntax is as follows:

User-agent:

Disallow:

�User-agent� are search engines' crawlers and disallow: lists the files and directories to be excluded from indexing. In addition to �user-agent:� and �disallow:� entries, you can include comment lines � just put the # sign at the beginning of the line:

# All user agents are disallowed to see the /temp directory.

User-agent: *

Disallow: /temp/

Robot.txt tells to Google that which page should be crawl in the website.
