Can it at all have to do with Googles Indexing of those changed pages... could that at all effect the ads on other pages?
i have a rev crash 50% since April start for the major site.
my revenue has gone down and my traffic has taken a hit.
There are two reasons why publishers experience 50% drops. The first one is the dollar amounts are low. So it's easy to drop from $20 per day to $10 per day.
Why is it easier to drop from $20 to $10 than from $1000 to $500? 50% is 50% no matter how you look at it.
I thought it was pretty obvious why.
Someone who loses $10 when they are earning $1000 a day is a piss in the ocean.
But someone who earns $20 a day and loses $10 is a big deal. That is why percentages mean little when earnings are on the low end of the scale.
Hah? Run that by me again. How is $10 from $1000 50%?

Statistics are easily manipulated, plus, Lapizuli's positions are hardly defensible. Even though his arguments sound great, they're full of miscomprehension concerning the efficacy of algorithmic models.

Great post, Lapizuli.
Just because something is bigger doesn't mean that it's more accurate.
He makes assumptions that aren't always accurate.
For the last 2 months, a majority of the publishers, including old timers, are reporting:
1. Massive drop in revenue epc/ecpm
2. Problems getting pages indexed
3. Excessive amount of public service ads
I've been with adsense for almost 7 years now and have never seen it this bad, or this many people affected. I don't want to be one for exagerated hyperbole, or to say the sky is falling, but I will say where there is smoke there is fire and smoke is coming out of the adsense house.
