I'm the webmaster of 6 italian sites about lists of addresses (list of professions, list of shops, list of restaurants, etc). One of this site is www.cerca-in-internet.com
From june to the half of september, I had near 10.000 pages viewed, and near 100$ a day from adsense.
In september 16, ALL the pages indexed on google disappeared (all the same day!!), and now pages viewed are only 100-200 a day.
Anyone could explain me WHAT'S HAPPENS??
