Permanent Redirect Not Found Search engines may think www.domainname.net and domainname.net 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. I ran my website through website grader and it came up with this error. I'm going to implement a 301 redirect in the next few hours but how much does it matter? I've done all my marketing and link building to www.domainname.net when I guess I should have been doing it for domainname.net. I just checked in Traffic Travis and for my domainname.net the backlinks are coming up as 3, while the backlinks for the whole site are appearing as 3255. Have I made a stupid mistake?
