I've been sending some of my cheapest 404 traffic to this page
http://www.freevaluedeals.com/
and here is a chuck of my stats ..not bad extra for overflow traffic
Page impressions / Clicks Page /CTR / Page eCPM [?] /Your earnings
4,159.......................167........4.0%.....$2 2.53..............$93.72
8,461.......................536........6.3%.....$9 .89................$83.69
6,415.......................253........3.9%.....$2 0.56..............$131.92
Right now my stats are low ..i need to spend a bit of time and tweak them .. they were better.
