I just found out about this new type of advertising offered by alertbar.com. They let publishers put html code that displays a small unintrusive bar at the top of the page with an ad. Since whenever a user has to move the mouse to the top of the page for any action (to type in the location field, for back button, stop button almost anything), the user mouse will be going over the alert bar. The color of the bar changes when the mouse is focused on it. So, as the mouse quickly moves over the bar, it sort of creates an alert effect and this may make many users to pause their action and take a note of the message (your ad) on the bar.
Their pricing is very low as well. Just $0.35 CPM. Yes, that’s right. It’s 35 cents for 1000 impressions. And a mere $300 for 2 million impressions! Check them out at alertbar.com.
