So on many product pages over at Amazon there is a section titled:
Customers Viewing This Page May Be Interested in These Sponsored Links
and it has what basically look like Text Ads in a block. You can see them here right before the customer reviews: [amazon.com ]
I have someone who is interested in having their advertising show there but I can't figure out where the ads are coming from. The only thing I could find from Amazon was:
The Sponsored Links placement includes Amazon Clickriver ads for services and a range of products from third party ad networks. Sellers using third party ad networks cannot directly influence which products are included in this placement. The only way to ensure your products are advertised to Amazon customers is by using Amazon Product Ads
The ads all go through a9.com and of course all Clickriver stuff just points you to Amazon Product Ads. Does anyone have any info on this?
A little bit about Amazon Product Ads, it's a CPC program that drives quality traffic and conversions and a good deal of traffic. I'd highly recommend it, yes your ads show up I believe as text but mostly as actual product listings, if you look at "Product Ads from External Websites" those are examples of Amazon Product Ads.
In terms of the management involved, Amazon does not have their own reporting system or tracking pixel to track conversions, so you'll need to do that on your own and append your URLs with Google Analytics code or other 3rd party tracking so you can optimize your campaign.
Last quarter it was the largest driver of traffic for all comparison shopping engines so your management of the account will suck up some resources especially if you have a good number of products in a high-trafficked category.
Also, recently Amazon Product Ads came out with a traffic extension program where Amazon is going to leverage a 3rd party publishing network and a complex product recommendation algorithm to drive even more traffic to online retailers. Right now the program is free in beta version and does not drive much traffic, but I would not be surprised if it soon challenged Adwords as one of the largest ad networks out there.
Amazon, with so much rich customer data, will be able to construct highly targets ads on these 3rd party sites.
Hope this helps. Bottom line: Definitely give it a shot!
