User-agent:Name of the robot comes here for eg. Googlebot

Disallow:The name of the file or directory comes here (This instruction disallows the files/directory from being indexed). Here are some examples:

Disallow:/admin/

Disallow:/personal/

• Below is an example of a Robots.txt file that instructs bots not to crawl any file ending in .PDF

User-agent:*

Disallow:/*.pdf

The Robots.txt file can also have multiple sets of instructions for more than one bot. Each set of instructions should be seperated by a blank line. There is only one Robots.txt file for a website.

What are Directories and how do they differ from Search Engines?

Directories are sorted listings of websites that are maintained and approved for listing by human editors. Directory databases comprise of websites that have been manually submitted by the website owners or website editors, unlike search engines which make use of automation through spiders and bots for searching new websites, directories make use of human intelligence to ensure that each new site submitted to the directory meets certain standards and is placed in the appropriate category within the directory. Some of the important directories from the point of view of the search engine optimization are:

• http://www.dmoz.org
• http://dir.yahoo.com
• http://www.looksmart.com
• http://www.rocktheadored.com
• http://www.etup.org
• http://www.searchsight.com

A good site for locating directories is www.addurl.nu which lists several directories. Since most directories offer free listings, it is always a good idea to get listed in as many as possible since it is viewed favorably by most major search engines while ranking the site in the search results.
