With the advent of dynamic database driven pages many moons ago, you can probably access the same information from multiple URLs.  How does that affect your Google rankings?  Probably adversely.  Enter the canonical URLs via an HTML meta tag which you put in the head part of your document:

 <link rel="canonical" href="http://www.example.com/directory/page.html" /> 

Canonical URLs allows webmasters to provide a "preferred" or "canonical" link that specifies the preferred version of the webpage as part of SEO.  If you have multiple ways to get at the same content, then you should be specifying a canonical link to the preferred URL for SEO.

According to Google, canonical links are just a directive but "strongly honored" accord Google search guru Matt Cutts. So it's about time you start thinking of canonical URLs.
