I am getting this problem here:
When I went to website grader... I got this...
|Search engines may think mydomain.com and www.mydomain.com are two different sites.You should set up a permanent redirect (technically called a "301 redirect") between these sites. Once you do that, you will get full search engine credit for your work on these sites.|
What to do so that the search engines treat the url's as the same site?
I even have tags indexed and therefore my content in the blog below shows up as duplicate content which is bad in the search engines.
