Now that March is over, my Adsense Performance compared to the first quarter of 09 shakes out like this
Clicks up +351%
Page CTR up +685%
Page eCPM +660%
Earnings +337%
Rev/Click -3%
All elements are up significantly except Rev/Click.
NOTE: I did remove non-performing ads and worked on re-design in the later part of 2009.
I track by day of week this year / last year and graph out the Rev/Click.
I don't believe in comparing April 1 of 2009 to April 1 of 2010 because April 1 of 2009 was a Wednesday and this year it is a Thursday.
Surprisingly (or maybe not) the graphs comparing TY to LY by Day of week look almost identical on Revenue per click, with this year being slightly below 2009.
Applying a Linear Trend line I get an almost parallel set of lines again with 2010 being on the bottom.
My Revenue per click is down 3% totally but on a graph is almost mirrors Last Year though the actual rev/click varies by 100% with a high and a low. In other words some days it = Y and others it is (Y-50%)
Is a 3% reduction in the amount paid per click the "X Factor" so far this year.
It is so consistant that it jumps out at you. (At least for my sites)
Either this means my niche is simply paying 3%less
or
G is keeping 3% more of the revenue,(giving themselves a raise),
or
it is just a random fluctuation and doesn't mean anything.
What is your X Factor? The Percent (+/-) when comparing your (Total 1Q Earnings divided by your clicks) 2010/2009?
Don't want your Rev/click but the Percent difference between TY and LY.
