I use the product links (the iframes which show a link and a picture of the product). Thing is, rather than showing the product links they're showing a standard amazon banner. Is amazon broken?
Iframes at Amazon are intended to display those banners, just another way to do it instead of javascript or the <img> tag itself.
Not really sure I explained myself well enough. Using the wonders of print screen and paint heres what I mean:
Now I see, you mean the orange banner. Those banners are delivered when there are not enough products available matching the chosen category and your keywords. To avoid getting them, reduce the number of keywords, or change them total or partially.
