Hi, This is really confusing me now, people say ignore it but I can't. My site is setup currently as http://domain.com without www but both work. All my SEO stuff was done using www. and some using non-www I setup my Webmaster Tools as www. In the below image you can see that non-www gets more impressions than www. as it appears in Google natureally as non-www because I have not done a redirect or amended .htaccess. Is this bad for SEO, should I add non-www to Webmaster Tools and then set the preferred domain to www. ? All backlinking has been done on www. but it seems to get less impressions than non-www... From what I have read when my site can be viewed as www. and non-www it affects ranks as Google will rank both sites. What should I do? Ideally I want Google to see it as www. only instead of both so that all impressions and views/clicks etc are controlled on one domain not non-www. Any advice will help, If you are going to post and ask me to delete Webmaster Tools or use something else don't bother because I won't do that as Google will de-rank me like last time so just advice please. Thanks and + rep to helpers.
