redzone, a member at WebmasterWorld received an announcement from Shopping.com and soon after, Bizrate - about CPC price increases due out the 1st of February. In his post he said:
The most notable subcat increases are:Electronics -> Flat Panel TV's - $.40 to $1.00 Health & Beauty -> All SubCat's - $.15 to $.50 Home & Garden -> Small Appliances - $.30 to $.50 Jewelry -> Watches - $.40 to $1.00 Kids & Family -> Strollers, Car Seats, Cribs & Carriers - $.30 to $.75 Office - MultiMedia Projectors - $.40 to $1.00
He also believes this is happening because merchants are using the free conversion tracking utilities provided by Shopping.com. His logic; now shopping.com knows how much your ROI really is and can rationalize taking a larger piece of your pie. He also adds that soon after Shopping.com's announcement, BizRate followed suit with an increase in CPC prices.
