I'm not sure how many people have started using the amazon native shopping ads, but I am having good success with the them so far. They look awesome and are converting well on some of my review websites after the content at the bottom of the articles. I have also placed them in the sidebar of 2 of my authority websites with very good conversion rates. If you don't know what these are you can find a tab link at the top of your amazon affiliate account. They will read your page and put associated products (up to 6) on your page. So far for me they have come up with high converting products which are very relevant (if not the same) items to what is on the page. I am having amazing success. Just thought I would give you a heads up in case you haven't noticed the new tab on top of your amazon affiliate page. It could be they are working so good because of the holiday season, but I have a feeling they will have a permanent place on many of my websites. They are a perfect fit for review sites, give them a try!
