A month ago when i logged in to my webmasters tools it showed me that my site had 0 backlinks!! But i am sure that it showed more than 200 backlinks some days back. So I waited for over a month thinking that google may update it. But still it shows 0 backlinks. Half of them are from digitalpoint from my signature. But why isn't google counting them?? I even had backlinks from digg, youtube, etc. Can anyone please tell me why is this happening?? Thanks.
Google rarely shows you all of your backlinks. Perhaps the pages with your links ended up in Google's supplemental index. I notice that you have both http://z-revolution.net/ and http://www.z-revolution.co.cc/ This is a blatant example of duplicate content. I think Google probably penalized your site(s). You should just keep one of those domains active and use a 301 redirect for the other one.
Try to check it again dude. Maybe that time, webmaster tool have error or google is in update process.
look carefully i have already used a 301 redirect!!!!! and this backlink issue happened before i bought http://z-revolution.net. So there was only one domain at that time which was http://www.z-revolution.co.cc/. Anyone knows what may be the problem?
