Striking a balance between how much you should spend on marketing and anticipated revenues is a challenge for any product developer. It’s especially a challenge for Android app developers because of the low price point and the fact that Google takes a 30% share from all sales. So, the question that’s often asked is, how much marketing is needed for profits to be realized?
Think of marketing in terms of driving visitors to two locations to learn about your app: the Android Market and your app product website. You will spend most of your time optimizing your product website, just like any other web-based business. However, you should always look for opportunities to update your content on the Android Market as well.
