Dear All In the past few months i found in my webmaster tools all black links link to my home pages was gone I continue build links link to my home page ,but no effect at all! I sudden realized maybe the domain name resolution problem! I check the url:www.mydomian.com in google but the result was the: mydomian.com does it means? my www.mydomain.com this url not index by google? So it means whether I do how many BL to my www.mydomain.com, will no use! So what should i do now? any good suggestion?
