What about implementing all types of Ads in a ecommerce site?

For instance there are, Floating ads, Banners ads, Sidebar ads, unicast ads, small ads, pop-up ads. Would that be reliable or ok to implement and use all this types of ads in e-commerce site?

I would also like to know where and how to distribute all this kinds of ads through the site. Which ones to put in the homepage, and in the subsequent pages?
