Short... no key terms... ie. domain.com/category-name/item-number.
After we did it:
1. Our user metrics went up (apparently having less "spammy" URL's does make a difference.
2. Zero negative affect from Google... if anything our traffic improved SLIGHTLY... less than 2% difference hard to tell if it was from the url switch.
3. BUT BE CAREFUL! Don't make a mistake!
We did it for branding... I didn't like the long urls... and for SEO; we were hit by panda and one of the metrics they measure may be spammy signals like long ridiculous URL's... I didn't expect that user metrics would improve 5 - 10%...
