I have a client that has a yearly event. Each year they create a new, complete website for their event in a subdirectory on their event's domain. Last year their URL had this structure:
http://event.domain.com/spring2012
This year, they'd like to use:
http://event.domain.com/spring13
Before they move ahead with it, they've asked me whether there's any benefit to keeping the same structure. My only thought was that Google might prefer a consistent structure, but I'm not sure if it actually matters in this case since they are completely separate sites.
So I'm wondering, does this matter to Google, and/or are there any other possible downsides to using this slightly different URL structure?
