I just learned of a way to create custom URLs in WordPress that are SEO friendly. It involves changing the Permalink structure to use Categories and Post Names in the URL. Makes a lot of sense and is also easy to do! I’m using it here, if you look up at the address bar for an example.
I documented it on our Sites@UCI blog if you are interested.
