With more than 700,000 apps available in Apple’s App Store, promotion means everything. But when it comes to advertising, it’s important to know what is and isn’t working.

In April, Google began offering Android developers the ability to track their apps’ downloads from their AdWords campaigns. Today, the company announced that this functionality is now available for iOS as well.

This means that you can now track downloads of your iPhone, iPad, and iPod touch apps through AdWords as an AdWords conversion — meaning a download that has resulted from clicking on an ad. However, this functionality is somewhat limited.

Google noted that it can only track iOS downloads driven by ads served within mobile apps and not downloads that originated from ads on Google Search. While this limits the insight offered, we imagine that you’ll still have a solid understanding of which campaigns are the most effective. From there, you’ll be able to determine whether to revamp your app promotion strategy or continue moving forward with the existing plan.

To set up iOS conversion tracking you’ll have to create a code snippet in your AdWords account and install it in your app.
