One great benefit to having your app on the Amazon Appstore for Android is cross-promotion. Cross-promotion is a form of marketing where customers of one product are targeted with promotion of a related product. Amazon.com has millions of customers, and those customers purchase tens of thousands of products every day. With so many great products (and customers), we have the unique ability to employ cross-promotion, even across product categories.

So, what do you need to do? Nothing! By default, apps that are published in the Amazon Appstore qualify to get picked up in the cross-merchandising widgets and promotions.

In the below image, you’ll see the product detail page for an Android app. In the Customers Who Bought Related Items Also Bought widget right below the general app information, you see that our site is automatically recommending a USB cable to the customer who is interested in this app—simply because other customers purchased similar items.

Similarly, in the following image, you can see the Customers Who Bought This Item Also Bought widget. This form of cross-promotion allows customers to make informed decisions about which apps they purchase while also showing them additional apps that might interest them.

Another Amazon widget that can benefit your app is the What Other Items Do Customers Buy After Viewing This Item? widget. Below, the widget is appearing on the product detail page for a tablet device and is advertising an app that was purchased by a customer who also purchased the tablet.

All of the above-mentioned widgets are automated, but we also have the ability to manually cross-promote your app. In the following image, note that on the product detail page for a hardcover copy of this Dr. Seuss book, we’ve added a recommendation for the related Android app.

Cross-promotion means customers can discover your app in a number of ways—not just by searching on the title or category. And over time, your app sales have the potential to increase, purely based on this cross-promotion. That’s never a bad thing, right?
