    • Google rolls out pay-per-action. Google's got a new advertising scheme, and it's set up to help small-time advertisers avoid the dangers of click fraud. Instead of just paying by the click, advertisers can set up predetermined actions the user must go through, such as purchasing an item or browsing a certain section of the site. The new system has sparked controversy in the blogosphere as a potential destroyer of smaller affiliate marketing services.

    • Congoo launches News Portals. Premium news content distributor Congoo (previous coverage) has rolled out a customizable single-page-aggregation service that pulls stories from user-selected topics. Users can also create their own newsfeed by using keywords that filter upcoming stories.

Users can then track widget statistics using MuseStorm. (via SexyWidget)
