General Questions

  • What is AdWhirl and why should I use it?

    • AdWhirl is a free, open source tool that helps you make more money from your iPhone or Android app. It enables you to serve ads in your app from any number of ad networks as well as your own house ads. By using multiple networks, you can determine which perform best for you and optimize accordingly to maximize your revenue and fill all your inventory.

  • Do I have to pay to use AdWhirl?

    • No. Both the AdWhirl Client SDK and Server code are free to download and use.

  • Does AdWhirl take a cut out of the revenue that I get from the ad networks?

    • No. AdWhirl is a free service to the mobile community, and we believe that it is a necessary component of a healthy mobile ecosystem.

  • How will I get paid?

    • You will receive payments directly from the ad networks you work with. AdWhirl does not have any insight into your business relationships with ad networks and does not have access to your eCPMs or earnings on the ad networks you use.

  • How is AdWhirl maintained?

    • AdMob has dedicated resources focused on improving the AdWhirl product and looks forward to working with the developer community at large to improve the product.



  • Why did you decide to open source the AdWhirl Client SDK and server?

    • AdWhirl was acquired by AdMob in 2009. We decided to release it to the open source community so that ad mediation can be transparent and open and unbiased. Developers can review the code and then decide which ad networks to include in their own custom build.

  • I have an app that produces a lot of traffic. Can you guys handle a lot of traffic?

    • Yes. AdWhirl was built to handle massive amounts of traffic, and many apps that use AdWhirl generate millions of impressions per day, so you shouldn't worry about scalability issues with AdWhirl.

  • How do Allocation Percentages vs. Backfill work?

    • The former is used by AdWhirl to manage the first requests that are sent to the ad networks. These allocation percentages represent the percent of initial ad requests that will be sent to each network. (Please note that your allocation totals must add up to 100% before you'll be able to save your changes.)

    If these requests come back unfilled, AdWhirl will then roll over to your backfill settings, starting with your #1 priority network, and continuing down.

    If you'd like to use only priorities, and not percentages, to request ads, you should set 100% of allocations to your #1 priority ad network. This way, all requests will be sent to this network initially, then unfilled requests will be filtered down to your lower-priority backfill networks.
