An improved version of the previous example is a modified URL that removes the dynamic paramters and hides them in a static URL. This static URL is then mapped to a dynamic URL using an Apache module called mod_rewrite. The ref_id paramter previously alluded to is also not present, because those types of tracking parameters usually can and should be avoided:
http://www.example.com/Products/1/
http://www.example.com/Products/2/1/
The impact of numeric URL rewriting will likely be negligible on a page with one parameter, but on pages with two parameter or more, URL-rewriting is desirable.
This form of URL is particularly well-suited to the adaption of existing software. Retrofitting an application for keyword-rich URLs, may present additional difficulty to implemented.
It is important to realize that rewriting a dynamic URL only obscures the parameters. It prevents a search engine from perceiving that a URL structure is problematic as a result of having many paramaterers. If underlying problems still exist on a web site, usually in the form of duplicate content, a search engine still may still have difficulty indexing it effectively.
The improvement should not be implemented on a currently indexed site unless the old URLs are redirected to their new counterparts. Other web sites may cite them event if you do not, and this may create a duplicate content issue, as well as squander link equity.
