In my last post I suggested CPM is falling due to a slow economy. Maybe that’s not the case. I think it was four sub-$2 CPM days in a row that threw me off. But as my daily traffic has fallen, my daily sample of the total ad pie has shrunk also, so my daily CPM measurements aren’t as telling as I’m used to.
Several consecutive slow days was probably due to random chance, because it’s Nov 20th and my average CPM compared to last month is only $.15 lower than October. September was my best month ever and October wasn’t that far off from September.
The big news today, according to IAB, Internet advertising is up from last year. Sure ad growth isn’t accelerating but I’m optimistic and building more websites.
