Google CPM
Google announced a beta feature for AdWords that will allow advertisers to target ads to thousands of specific content sites in the Google network. Google will test a cost-per-impression (CPM) bidding model for AdWords ads, and for the first time advertisers will select which websites their ads are displayed on.
Google has posted an article about google CPM advertising
“With site-targeted advertising, advertisers will simply set a max CPM—that is, the maximum price they’re willing to pay for every thousand impressions their ad receives on a particular site.”
This should add an interesting twist to the current adwords system. This model is different from other CPM (cost-per-impression) models, where advertisers must pay a fixed CPM. Keyword-targeted ads will still follow a cost-per-click bidding model, where advertisers set the maximum price they’re willing to pay for each click their ad receives.
This piques my curiosity as to how to show or not show these CPM ads on certain sites. Will publishers have the option to opt in or out of showing CPM ads on their site. I am sure that the CPM program will work better than RPC on some sites but not as well on others. This is just another sign that online advertising is becoming more and more diverse, spawning multiple forms of advertising models, and causing advertisers to bid on highly targetted traffic.
