For the pass few days I have been making $10+ a day (with less impressions) since i went to 5th with the keywords proxysites (url: proxysites.org). I get around 300 imps a day. Yesterday I got only $2.33, the day before i got $11. The payment seems to vary, look at today, so far 22 clicks and made $8.00, whats causing it to vary so much??
