One thing you need to make sure of is to keep your URLs as short as possible. They should not be longer than 70 characters in length. You also want to make sure that your URLs don’t have too many sub folders. For example, www.domain.com/locations/tampa. “Locations” is a sub folder, so is “Tampa”. So you never want a URL to look like this: www.domain.com/subfolder1/subfolder2/subfolder3/subfolder4/subfolder5/subfolder6/. The most sub folders you would want to use would be two or three if possible. Also, each sub folder should be named well.
