Yahoo Search update someone's rank has been gone as well as revenue September-26-2007, Yahoo search update, nightmare
~ 7% up to previous months, the last 10 days or so however have been much better than early 20 days of October: PR down - traffic UP eCPM same or little up CTR always same (=2 digits)
I had a slight increase, but the last week was terrible. Over 50% decrease. My affiliate links are performing the same, so I highly doubt I was smart priced. I am getting 3 times bigger ecpm with affiliate links than with adsense.
I'm pretty sure I got smart-priced on one of my sites. It earns about 20% of what another one of my same site earns with less clicks.
Smart-pricing theoretically would affect ALL your sites, so if it's only one, probably not smart-pricing?
Now in October Adsense is my 4th best revenue source, after Adbrite, Bannerconnect and Valueclick. I am barely breaking 20 bucks a day with adsense, when giving it ~100k impressions across many different sites. I'd replace most of my adsense ads with something else if the alternative just didn't make the webpages look so ugly.
