I just launched a site and it set at "Don't set a preferred domain" on Webmasters Tools. I received this alert recently: "Your site is indexed as http://mywebsite/ not as http://www.mywebsite/. If you want to see all data for your site, you need to add and verify http://mywebsite/ as well. " Im not entirely sure what this means. Can someone elaborate more it, along with pros and cons? I've setup many sites before on Webmaster Tools but never received this before. The only variable that is different with this particular site is that, it's hosted in some weird company I never worked with. ARe errors like this hosting dependent? Thanks in advance for any help.
Google bots treats your website in different way. like if you set recommended http://abc.com then it treat as http://abc.com and your pages will index in same manner with out www. if you set recommended http://www.abc.om then your pages will inded in same manner with www.abc.com google bots considering www.abc.com and http://abc.com as different. so for that you have to redirect not www to with www using .htaccess file if you are using apache server.
