How Do They Target The Ads in Hotmail Like This?
Let me explain. I am a hotmail user and I noticed that when I am reading my emails I get customized banner ads on the side. For instance, the other day I was looking for prescription sunglasses on Google etc and then when I checked one of my emails a banner for prescription sunglasses showed on the right. This happened a few times to me now with different products and I am puzzled as to how this is done. I think this type of marketing can be a gold mine if utilized right.
Any insights would be much appreciated.
