We didn’t use PPC, but it is certainly a viable option for you if you have the budget. The Google Adwords keyword tool will help you come up with list of keywords most relevant to your target audience. You can then use those keywords in your promotional materials, on your website, in YouTube tags and in your articles about the app.
We’re keen to test the effectiveness of Quick Response (QR) codes in the promotion of the app. Many marketers shy away from them as they are ugly and overall usage levels are perceived to be low. However, you are able to customise QR codes and our feeling is that they are here to stay.
Once you have a QR code, I’d recommend exploiting traditional means of promotion, like posters and fliers. The magic of the QR code is the instant response. Anyone with the right smartphone can download your app immediately by scanning your QR code at the moment they see it on a poster.
