for those of you who run ecommerce sites... could emptyspaceads help boost sales?
The idea with emptyspaceads is that your site's empty space isn't providing you any value beyond simple aesthetics. Firstly, the ads only appear when when your user's mouse is in the empty space of your site, and they only appear within your site's empty space. So for some users, they'll never see the ads.
You can create your own TextAds, ImageAds, or even HTMLAds. These allow you to drive users to content on your website or blog that you monetize well (a CafePress store for example), or behavior you'd like to encourage (like more RSS subscribers). (See our blog for an example how we use emptyspaceads to get more RSS subscribers to our blog by embedding the feedburner chicklet). Or our Sample TextAd, ImageAd, or NetworkAd... our check out our demo.
I think the potential interest for e-commerce sites is using our product to offer a 5% or $5 off coupon that appears in your wesbite's empty space. I think it's like putting a coupon outside a department store... not everyone who sees it will want to pick it up... but it will give an excuse for more frugal people to buy your products & services.
I think if you could control how many times the ad appeared to the same customer, it might be worth testing.
The annoyance and distraction factor for an ecommerce shopper trying to complete their transaction may make ecommerce sites slow to try it out.
But like you say, if it was used to drive traffic to special offers or coupon codes and not shown every time the customer got lazy with the mouse, it could work. Might even work for upselling lower priced products.
