In my feed reader from SEO Roundtable this morning... thought some might find it useful.

One thing that I would strongly recommend and agree with in the thread is that you should always try to keep your blog on your own domain. Do not use a blogspot.com domain or something similar. Try to keep it on a domain name you control and own. This way if you ever decide to move from one domain to another, you have the control to set up the proper redirects and keep all your link popularity.

Thank you for this rob.

Another tip is to make sure you keep your permalinks the same or configure your .htaccess (or use plugin for Wordpress) to forward incoming requests.
