In the last few days saw to my horror that my website (www.thewhippet.net) dropped from the first page to the second and today to the third when I search for the word "whippet".
I cannot see any reason for it as I was always committed to providing useful and original content for my visitors.
Could the reason be the fact that I host user generated content?
I think should not be penalized because obviously visitors participate with their contributions because they like my website and they feel comfortable about adding content!
