Thanks Brad.

Incrediblehelp I got your points and will make changes on those pages but I don't think this getting the same result is directly related with the quality of content or links (indirectly of course related). Issue here is not ranking good or bad, but (at least on my browser) I keep getting the same SERP for quite a few search terms, which suggests there is probably a cap for my site in Google. And not managing this duplicate content issue is probably the key.

I think like what Brad mentioned, we are getting the domains (which are not even domains, but supposed to be redirect for typein URL traffic like printeink.com) that are not real in the search results (and most cases performing better than the real site).
