Key Points

  • Mobile ad mediation solutions were initially built to help app developers easily monetize their apps with ads. A few mediation partners have come to be known as the “top providers.”
  • Over time, it has become clear that mediation solutions have a few key problems, and don’t come close to the level of transparency and technological advancement available for web monetization.
  • Playwire’s RAMP for App solution helps app developers overcome those problems and provides a more comprehensive solution than any ad mediation platform alone.

Frequently Asked Questions

 

Frequently Asked Questions

What is an App Ad Mediation Partner?

App mediation partners have built solutions to monetize mobile apps with ads. They are integrated into an app by the developer using a pre-built SDK.

App ad mediation partners provide centralized access to multiple ad networks in a single software development kit (SDK) integration. They then work to increase your cost per mille (CPM) rates by algorithmically selecting the best ad network to fill each programmatic call for bids.

What are the Biggest drawbacks when it comes to App Mediation solutions?

When app mediation solutions first entered the market, they were great. They solved a problem that app developers had little way to solve on their own.

However, over time it became clear that app mediation solutions didn’t quite measure up to the technology used for website monetization. In particular, traditional app mediation comes with a few drawbacks:

  • Every SDK requires integration: To incorporate more sources of demand means integrating (and painstakingly maintaining) many different SDKs.
  • Waterfall auction means losing chances at higher bids: Because of the auction process used in mediation solutions, app publishers regularly miss out on the opportunities for higher bids.
  • Lack of revenue transparency: The app industry also hasn’t quite matched up with the level of transparency available on the web side. Traditional mediation solutions give app publishers no knowledge of how much an impression is being sold for, meaning they have no idea what “cut” of that impression is held by the mediation partner.

The Complete Guide to App Monetization for Publishers

A Better Solution

So, Playwire decided to change that. We’ve taken our 17+ years of experience monetizing websites and translated the best parts into our RAMP for App solution. It incorporates demand from all the top mediation networks and works to unify the auction with in-app header bidding.

Rather than integrating a single app mediation partner, you can integrate all of the following in a single SDK:

  • Google Open Bidding
  • Amazon Transparent Ad Marketplace (TAM)
  • Prebid
  • Google Premium Demand
  • Full-service management of meditation partners

Not only do you get access to quality demand in a single SDK, but Playwire’s approach to in-app header bidding means you don’t miss out on opportunities for higher bids, as is common in the traditional waterfall approach built into most mediation integrations.

How do mobile ad mediation platforms help app developers manage multiple ad networks simultaneously?

Mobile ad mediation platforms are essential tools that allow app developers to connect multiple ad networks through a single SDK integration. Rather than individually implementing and managing several ad networks, developers can use one mediation platform to optimize their ad inventory across numerous demand sources. This simplified approach not only streamlines technical implementation but also creates competition among networks, ultimately increasing ad revenue through higher fill rates and improved CPMs. Playwire's RAMP for App solution takes this concept further by incorporating in-app header bidding technology that ensures you never miss opportunities for higher bids.

What are the different ad formats supported by top app mediation partners?

Leading app mediation partners support multiple ad formats to maximize monetization opportunities across various app types. These formats typically include banner ads, interstitial ads, rewarded video ads, native ads, and rich media ads. Each format serves different purposes within the user experience - banner ads for consistent revenue, interstitial ads for natural transition points, rewarded video ads for engagement-based monetization, and native ads for non-disruptive integration. Playwire's comprehensive solution not only connects you with mediation partners supporting these formats but enhances performance through advanced optimization techniques that consider both revenue potential and user experience.

How does in-app bidding differ from traditional waterfall approaches in mobile ad networks?

In-app bidding represents a significant advancement over traditional waterfall approaches used by most mobile ad networks. While waterfall mediation sequentially calls ad networks in a predetermined order (potentially missing higher bids from networks lower in the sequence), in-app bidding allows multiple ad networks to compete simultaneously in real-time auctions. This unified auction approach ensures publishers receive the highest possible bid for every impression. Playwire's RAMP for App solution integrates true in-app header bidding technology, similar to what's available for web publishers, giving app developers access to a more efficient and transparent monetization method that consistently delivers higher ad revenue.

How can app publishers optimize ad placements to balance user experience and revenue?

Strategic ad placement optimization is crucial for mobile app publishers looking to maximize revenue without compromising user experience. Effective optimization starts with identifying natural breaks in user flow for interstitial ads, creating value exchanges for rewarded video ads, and finding non-intrusive locations for banner and native ads. The best mobile ad mediation platforms provide placement testing tools and analytics to help identify optimal configurations. Playwire takes a data-driven approach to ad placement optimization, analyzing user engagement metrics alongside revenue data to find the perfect balance for each app's unique audience. Our team of monetization experts works directly with publishers to implement and continuously refine these strategies.

What reporting tools should app developers look for in a mobile ad mediation platform?

Comprehensive reporting tools are essential when selecting a mobile ad mediation platform. App developers should look for platforms offering granular insights into performance metrics including eCPM by network, fill rates, ad format performance, user segment analysis, and revenue trends over time. The ability to create custom reports, export data, and access real-time analytics is particularly valuable for optimizing monetization strategies. Beyond basic reporting, Playwire provides publishers with unprecedented revenue transparency, showing exactly how much each impression sells for and what percentage goes to each party in the transaction—transparency that traditional mediation solutions simply don't offer.
