My current url format is like this: http://www.wunderwedding.com/weddingvenues/venues/343/venue-name I want to rewrite my urls to a more friendly format: http://www.wunderwedding.com/weddingvenues/venue-name-343
Of course I will have to 301 redirect the old url to the new url. But what happens with the Facebook likes and Google+1 that users have already given to the old url? Will those be maintained?
