Hi,
AdMob wants everyone to have a great experience when using our
advertising platform. Therefore, we have spent a considerable amount
of time collecting and analyzing valuable conversion data that will
help advertisers understand what to expect when spending money with
AdMob, which I'd like to share with everyone. There are essentially
two types of applications an advertiser can advertise, Free or Paid.
Depending on the application, conversion rates for free apps are
typically around 10%, but vary from 5-20% depending on the app. This
means that for every 100 people who click on your advertisement,
roughly 10 will install your app. Many factors such as the appeal of
the app, effectiveness of the landing page, user reviews all
contribute to the conversion rate.
Historically, conversion rates are far lower for paid apps with
generally only 1% of clicks converting into paid customers. This means
that for every 100 people who click on your advertisement, roughly 1
will install your app. For many paid apps, this may result in a cost
per acquisition that may be higher than the sales price of the app.
