The cat is out of the bag, but I only read about them the other day, so forgive me as I have been busy with floods & stuff.
The new Google gadget ads allow:
“ advertisers the option to add flash, video, real-time feed, and transaction functionality to typically static display ads.” from mediapost.com
According to the article there will be no serving costs & they will be sold through the existing auction system & intergrated into an existing Adsense budget with CPC or CPM pricing.
(which is bloody genius, I can`t wait until it becomes the model for all ad channels IE TV, Radio, Magazine etc).
You dont have to be a genius to create them, anyone with web site experience can create them & there have been a suite of Google Analytics tools to track all metrics.
Nice work team Google.
