I currently have my Permalink set up as URL/%postname%/ I have taken a lot of time to put posts in categories, so now I am thinking I should change permalink to URL/%category%/%postname%/ (though I wonder about posts in 2 categories?) The site is relatively new but I have 500+ posts already. I know I can set up a 301 redirect just wanted to get some feedback on whether changing the permalink now is a good idea.
It would not be ideal in this case. The only time I keep stuff before post name is if its news related and requires a date. At the end of the day it really doesn't matter anyway. The question is not germane to SEO. hope that helps, Nigel
