For the latest two years i never bought or exchanged links. All what I have been doing is gathering links from blog, forums, newspapers websites and adding content. Every new PR or BL update my indexed pages and backlinks go down and by the way it's going, now, in the next update i won't have any backlink or indexed page!I beginning to think that Google blacklisted my web site Is it possible to contact them?
yes, you can contact them but you can't be sure they'll ever reply. and, yes, penalization against certain sites is possible. they usually have strong reasons when applying a penalization!
If you do n't buy links Your site won't be in Google.... None of mysites ( for which I did n't buy links) has been able to rank well in Google. and also PR....
That is not true. You don't need to buy link to survive. What happen with content creation? What happen with social networks? and many other things.
complete bollox. I've never bought a link in my life and I get good results in serps and workable pagerank
Sounds like you might be suffering from the infamous hand edit. That wonderful technique that Google uses to make its search systems seem far more sophisticed than they are. Oh, and to add a little confusion to SEOs lives.
If they get the indication your site is MFA site you will find your self deindexed quicker then you can type "google" and forget reinclusion...
