Alexa.com is now selling sponsor boxes in the 125×125 graphic format which have been made popular by blogs such as Search Engine Journal, TechCrunch, FederatedMedia and Mashable.
The ad spots are sold at a rate card price of $15,000 per month, which is somewhere around a $.50 CPM.
Alexa is one of the first major sites I’ve seen which is not a blog running these sponsor boxes, which goes to show they are becoming a more affordable and effective form of online advertising and brand building.
Given that Alexa attracts mostly bloggers and webmasters into its traffic ranking stats and service, the use of these ad spots only makes perfect sense.
