Now lets run a query “record yahoo webcam” on Google, now notice, results on the first page have at least two domains which have the exact same sub domains as the query. If you look further you will see similar sub domains sometimes from the same site as well. What’s interesting about it is that these are search term sub-domains, I’ll call them “Search Domains” of a site.

This technique certainly seems to work, however, I just hope someone used some technology to automate it. If it is automated it should create “Search Domains” either from the Tag Cloud’s or the Keyword log from your web analytics tool.

I did search a little bit to see if any such software is available which converts Tag Cloud to “Search Domains” but all I came across was “SubExpress” which is good for quick “Search Domain” creation but it does require certain amount of manual effort (which is not always bad).

Following article has a good read about how sub domains are better than folders or directories. I recommend you to read just “Pros” for sub domains or add-on domains, rest is not very important.

Do leave a comment if you know of any software which creates "Search Domains" based on Tag Cloud or Keyword logs and if you are planning to create one based on this article, keep me on the credit list
