Google has just introduced expandable ads — and the best part is that they’re not annoying like the ones you may be familiar with. Personally, I love this idea because it gives the advertiser more real estate for the ad without taking up a bigger footprint on the page. When a user clicks on an ad (I wish it expanded upon rollover) it expands into a larger size, displaying more information and larger pictures without taking the user to a whole new page. Google’s new AdSense expandable ads can even show a video clip. That’s pretty sweet.
