As bot-nets drive down the cost of sending spam and as spam filtering programs improve, some spammers moving from CPM to CPC pricing. The resulting emails have no links or tracking, just a jumble of text to fool the filters and an image to carry the marketing message. Like all spam, these image emails are unwanted and annoying, but also poetically surreal. The takeaway? If the CPM drops low enough, brand advertising becomes attractive even to direct marketers.
Google now provides time-of-day cost and click reporting. This is a good thing — more transparency helps advertisers.
