SEO Friendly URL deployment

There could be two very strong reasons for you to rewrite your URLs.
One of them is related to Search Engine Optimization (SEO). It seems that search
engines are much more at ease with URLs that don’t contain long query strings.

The other strong reason for URL rewriting would be the increase
in usability for web users, and in maintainability for webmasters.

Below are some examples of how URLs can look before and after rewriting:

Example 1:

* Dynamic URL:
* http://www.companyname.com/products/items.php?id=x&model=y&variety=z (before rewriting) Static URL:
http://www.companyname.com/x/y/z.html (after rewriting)

Example 2:

* Dynamic URL:
* http://www.example.com/cgi-bin/gen.pl?id=4&view=basic
(before writing)Static URL:
http://www.example.com/4/basic.html (after writing)
