Ahh. Another observer.
I think it's just the way google stats work.
I would LOVE to hear an expansion of this statement.
I just can't understand HOW they could "work" in this manner.
1. Does the first click reward you for potentially upcoming future clicks?
2. Then, are all subsequent clicks downgraded?
3. Or, do Adwords buyers say, "I will pay big money for the first click only? On all subsequent clicks, I will pay far less."
4. Does Google do this to "encourage" us early each day, to work harder? They could start out with one "bonus" click, and then pay us less on subsequent clicks, to even out to 68%?
5. Could it be "catch-up" - Google holds back money from the previous day, while it checks out those clicks, and then dumps the extra money into the first click of the next day? What about those occasions where there were ZERO clicks on the previous day? How long does it take Google to validate a click? 24 hours? I am thinking milliseconds.
I am certain of only one thing - this is weird. And I can offer no plausible, logical explanation.
