My site averages 7-10k uniques a day with visitors averaging 3.8 page views a visit. I have 2-3 image advertisements per page (image):
-728x90
-336x280
-160x600
from google adsense and if the ad can't show widgetbucks kicks in.
From these two providers I am averaging about $6-8 a day. I feel like I should be earning more, or no?
