As an adsense publisher of many years, I'm advising you not to even try and work out adsense daily earnings from a single website You've just got to accept that the earnings are going to vary wildly from day to day I've found the only way to get a steady daily adsense income is to build lots of different sites - then things even themselves out - it's also a lot safer than coming to rely on a single site to make your adsense money - as google can take a dislike to your site any time, and for no obvious reason
