We have had a bad drop in Google Adsense revenue after december 15th, this has been caused by a decline in adv visualisation and ppc revenue for the website www.impresaitalia.info.
Consider that we have only 2 kind of pages:
1 - directory ie: [login to view URL]
2 - company ie: [login to view URL]
We would like to solve this issue and optimize adsense adv in order to increase revenues
