Has anyone woken up and checked their adsense stats in the morning, to see like a dozen impressions and a few high quality clicks, and for the day your eCPM is like $300.00 ... That's scary... I'm glad that clicks are rare, so the impressions will bring my eCPM back down to nothing soon enough... Sorry, just had to post that...
My eCPM is always very high in the morning - because the impressions/clicks are relativly low you're not getting very good stats.. always evens out as the day wears on like you said.. I guess stress and worry is part of the fun of Adsense
For really accurate stats you need to look at them the next day. Then all the figures have evened out. On a side note I earn 8cents for impression with only 21 visitors. Hopfully this will be a high paying day.
