In mobile app marketing, a media buying model is the process and approach used in paid marketing efforts. The goal is to identify and purchase ads on channels that are relevant to the target audience at the optimal time, cost-effectively. Media buying is a process relevant to both traditional marketing channels (television, radio, print) and digital channels (websites, social media, streaming). When done effectively, media buyers achieve maximum exposure among their target market for the least amount of spend.
What is a Media Buying Model?
Our Media Buying Model works in tandem with our Ad Concept Model and uses a similar matrixed approach to systematize best practices for user acquisition campaign development. Any mobile app can leverage a unique combination of distinct UA strategies and campaign parameters to develop a robust, iterative testing harness for ongoing mobile campaigns across social platforms.
In its most generic state, our Media Buying Model looks like a matrix, prior to building out a mobile app user acquisition strategy. The entire matrix is tailored to a respective ad network and operating system requirements and constraints. Geographies, languages, and bid types are all modified based on the client’s needs. Each campaign is structured to meet specific goals at the intersection of strategies and parameters.

Testing on Android
Even prior to IDFA loss, Consumer Acquisition conducted creative and UA testing on Android because it was less expensive, and results translated well to iOS. We saved iOS testing for the rare clients without an Android app or those who were solely targeting iOS users.
- Unlimited ad accounts and campaigns
- Unobstructed deterministic tracking
- Comprehensive A/B testing with full reporting
- Distributed scale and spend across campaigns
- Rapid testing, unlimited test campaigns
- Success drivers easy to identify and scale
- Google Firebase enables tROAS, delivering ~15% lift on CPA campaigns with better user mapping
iOS IDFA Impacts
- Many accounts but only 9 campaigns, 5 ad sets
- SKAN tracking disabled after 24-48 hours (See AppsFlyer Conversion Studio below)
- A/B testing in DCO blobs, no asset reporting
- Fewer campaigns, higher budgets, more significant edits
- Restricted testing, only 9 campaigns
- Aggregate insights drive slower optimization
- Post-IDFA, iOS lookalike audiences have lost -65% of their reach and effectiveness
Testing on iOS with AppsFlyer
If you use AppsFlyer on iOS, we recommend testing through Conversion Studio, released September 9, 2021. Conversion Studio helps maximize LTV measurement for post-install activity by:
- Extending post-install event collection up from 24 hours to 72 hours and enabling D3 optimizations
- Tracking multiple iOS KPIs instead of only one in SKAN
- Measuring sequential events in the conversion funnel
- Marrying SKAN data to AppsFlyer attribution
Why use a model like this?
Our industry expertise comes from managing over $3.5 billion in creative and paid social spend for the world’s largest mobile apps and performance advertisers. We run our tests using our software AdRules via Facebook, Google, and TikTok APIs. Our Media Buying Model systematizes the UA campaign process, so we know what works, why it works, how to do more of it, and how to easily communicate status. Our process is designed to save time and money by optimizing quickly to reduce non-converting spend and to scale as pockets of efficiency are uncovered.
Below, see our Media Buying Model built out for sample mobile app campaigns across Facebook Android, Facebook iOS SKAN, Google iOS SKAN, and TikTok iOS and Android.

Measurement Limitations for iOS Campaigns
- Pre-IDFA Loss, iOS < 14.5
- Lifetime deterministic tracking provided in AppsFlyer
- 28 days of attribution across Facebook, Google, Snap, and Tiktok for bid optimization and creative testing
Measurement Post-IDFA Loss: iOS 14.5+ Limits
- User is anonymized; install and event reporting delayed 24+ hours
- Limited to a single conversion value; only one KPI can be reported back to your ad campaign
- Limited to 24 hours post-install for event attribution timeframe
- Event reporting is triggered after a minimum of 24 hours of inactivity
- SKAN provides 6 bits of information to hold your conversion event data
- This conversion value is set each time a user triggers specific events in your app, like a purchase
- Each time you set it, a 24-hour timer starts, and at the end of that timer, your conversion will be reported back to the ad network with a random delay buffer added
- Each time you set an event, the 24-hour timer restarts, potentially delaying your reporting to 64 days post-install!
