I don't know why? my site was getting 19,000 visitors daily now its gone down to just 2k to 3k. My site is not getting indexed for any of the popular keywords. what would be the problem.
In webmaster tools its showing. Links to my site is 42,000 links from 340 websites. In those 340 sites around 300 sites page rank is 0. Is that's what the problem?
I use free backlink Builder tools like socialmonkee and voltsrank. Shall i use those sites or not.
