It depends on which type of earning you are talking about. If its Adsense, then that's nothing, because some may or some may not click ads, even if the traffic is same. Check out the CTR, and if its still same, they you probably shall be receiving low paying ads.
If its the Hub Ad program, then that's a problem, because as far as I know they pay per view.
Oh so...... Did they not tell you about your new income sharing obligations and that Senor J Alverez and Jesus Gomez from M-Turk (Texas) each earned .05c from viewing and rating your page??? Unbelievable!
Last time I was paid was August 28th and have received enough to get payments each month. It's October 10 and I haven't received anything for September yet.Do I need to simply be patient or is there something else...
