If you are a developer with an app in progress or already in the App Store, the iTunes Affiliate Program is an absolute no-brainer. But this logic also applies for any other iTunes content, even free content.

The commissions are 7% on sales that result from your affliate traffic. In the case where a customer clicks on your link, to your app, from your website, and buys your app, that effectively means you have reduced Apple’s cut from 30% to 23%.

But it gets even better:

The affliate links carry over to other purchases made by the user that followed your link as well. If they browse more and decide to buy a competing product, you also win.

If your app is free, and they follow your link, then buy something totally different within 24 hours, you win.

This is not new, but this article just came out and I thought it was worth sharing for folks who might not be aware of the math. This program is a huge win for app developers and anyone with content they place in the App Store, even free content.

And, as pointed out by Anthony Waller, there’s no better way to manage affiliate links than with the excellent Blink app, written by John Voorhees.
