One error I’ve seen on a number of sites recently is that they are not setup correctly for both the www and no-www versions of their domain.

Ensuring canonical urls with .htaccess

I was reading an article about SEO on Red Cardinal and I came across the Canonical URL issue for the first time. Apparently Google may treat http://aidanf.net and http://www.aidanf.net as separate sites. I am inconsistent in the url I use for this site - sometimes I use one and sometimes the other. Even if Google doesn’t treat these urls as distinct it is good to have consistency in using one or the other. Luckily it’s easy to setup a permanent redirect of one to the other.
