Ive been getting 15000-20000 impressions per day and literally 2-6 clicks a day. Aparently the problem was having the directory offensive and pron in my url string.... they were: miscipedia.net/roflpron miscipedia.net/offensive those links still work but they redirect and show ads noW11!1!1
it's common knowledge the pron (as well as porn, and probably pr0n) are stopwords (=PSA).. but i'm not so sure about "offensive" .. here's a good list of stopwords: http://www.vaughns-1-pagers.com/internet/adsense-stop-words.htm
