If you have products to sell probably you need some reviews to convince your costumers, don't you think? Use "the magic link" or buy blog posts which will fancy them so that they can get into a real situatiion which is profitable.
If you need banner, that will help too. But again, we focus on the link and we need to be smart with the link. Otherwise, you will only waste your time tickled by your own fancy.
Well, that's all for today, ladies and gentlemen, keep tickling!
