My sites stuck on page 2 for now.
They won't be there long.Yesterday I noticed 2 parasites ranking in 2 big niches with hacked links in less than a week (top3).
Are your sites getting ranked after latest google algorith,
I see there is 30 day sandbox, but its not for long tail keywords.
I had started 4 sites, they are on page 3 itself even after building links from 100 pr3 websites.
