I have been working on some sites having keywords; incense, sticks, supplier in the domain name for the past one year. They were doing good for at least 6 months. Each keyword would rank within top 10 in Google.com. Now, after the Penguin Update, there have been a great loss in traffic as well as in keyword rank positions.


I had collected links mostly from low P/R sites.


Is that the reason?
