Each page on my site can be accessed by a shortened URL and normal "long" URLs. The shortened URL redirects to the long URL and the long URL includes an optional title that's not parsed (much like on this site, where http://webmasters.SE/questions/7/accepting-money
... is equivalent to http://webmasters.SE/questions/7
).
When pages show up in Google search results, there is a mixture of three kinds of URL.
http://site.com/Ab1C.html
http://site.com/content/123/full_name
http://site.com/content/123
Is there a way to encourage Google to use a specific format in the results?
