I saw this latest news Google Adsense that they’re going to launch their new ad type, the Expandable Ads. This new type of ad will create a more real estate for the ad and more interaction for the users. However this is only available in European and North American visitors only.

As what Darren Rowse commented in the topic:

OK - some mixed thoughts on this one. I’ve fully outlined them here but:
1. I like the idea and think it could be profitable for publishers…. but
2. again, you’ve excluded some sites showing these ads based upon publisher location instead of the location of their readers? Bizarre and annoying.
3. if I’m reading your post right advertisers can use CPC ads, capture the attention of readers, communicate a message to them about their brand…. and if our readers don’t click the ads we as a publisher get no benefit from them despite them expanding and covering up part of our site? I’d be much happier to see them as CPM based ads or at least CPC where we get some payment for a click.
4. Opting out - I’m not sure if you’ve ever tried to use the Ad Review center when you have a popular site but last time I looked I had hundreds of Rich Media ads appearing in mine - so many that when I viewed the Ad Review center 100 ads at a time that it crashed my browser. It’s a very slow process and on a popular site can take a long time to eliminate ads. The competitive ad filter option you describe doesn’t seem satisfactory to me either as wouldn’t adding an advertiser’s URL also eliminate any text or image based ads on my site? Most advertisers I see targeting my sites use a mixture of different ad formats not just one.

Of course my concerns as an Aussie publisher are irrelevant as I don’t get these ads on my site - but I hope that this first impression criticisms are of some help in improving this promising ad unit type.

I agree with Darren Rowse, advertiser gets to roll out their ads for branding and we publishers gets nothing from it. I hope that this Adsense Expandable Ads would be really beneficial for both advertisers and publishers. Ifyou want to read the whole blog post of it, click here.
