Excerpt of an e-mail from WidgetBucks:

International CPM Ads

Here’s an upcoming feature. In early December, we will start serving CPM ads to the non-U.S./Canada traffic. This will give you revenue, per impression, for your site visitors who come from other countries. This is designed to help publishers who have a blend of traffic from a variety of countries.

Our system will do the geo-location for you, determining where the visitor is coming from. Then we’ll either show the regular pay-per-click widget (to visitors from the U.S. and Canada) or show an ad that pays per impression (to visitors from other countries). You’ll see a new column, called “CPM Revenue” in your earnings reports.

As far as I know, and I don’t keep up to date on changes like this very often, this is a good thing. Last I heard Widgetbucks was not going to count traffic from international visitors at all. I also remember reading that this would be the best thing for Widget bucks to do. I do apologize but I can’t remember the person who said this. Nonetheless, it looks like Widgetbucks is changing around to accommodate the complaints of bloggers.
