As you may already know, Amazon manages a different associates programs for each country it has an online store on (e.g: US, UK, Canada, France, Germany, China, Japan and so on).
In fact, you need to maintain a separated associates account for each local Amazon store in order to earn the maximum commission possible.
If you redirect someone from the UK to Amazon.com and he prefers to buy from Amazon.co.uk you may lose your commission.
In order to solve this problem, I've developed a prototype geo targeting engine, that knows how to route the end user to the nearest local Amazon store, and add your special Amazon id tag for that store.
Do you think this kind of engine may increase your conversion rate ?
Do you know of any other product that does that?
