Hai. I just tried out these 2 recently.

CHITIKA
After 2 months (29/08/2012 - 31/10/2012)
7840 (US/CA Impression) - 50 Clicks - eCPM $0.18 - Revenue $1.43

INFOLINKS
After 2 days (02/11/2012 - 03/11/2012)
535 (Net Page Views) - 84 (Ad Views) - eCPM $1.64 - Earnings $0.38

Disappointed with the result from CHITIKA. INFOLINKS performed better on my end.

How about you guys? Appreciate any input. Thanks.
