Ad Mediation in React Native

Ad mediation is the essential "go-between" for React Native developers looking to maximize app revenue. Rather than relying on a single ad network, mediation creates a real-time auction where multiple networks compete for your ad slots. This ecosystem ensures that every impression—whether it’s a banner, interstitial, or high-value rewarded video—is sold to the highest bidder. The transition from traditional "waterfall" models to programmatic bidding has revolutionized monetization, often increasing earnings by 10% to 30%. By integrating a single mediation SDK, developers can access premium demand from giants like AdMob, AppLovin, and CAS.ai without the engineering overhead of managing dozens of individual plugins. Beyond higher eCPMs, mediation offers unified analytics, improved fill rates in secondary markets, and built-in A/B testing. For any React Native developer aiming for professional-scale growth, a robust mediation strategy is no longer optional. It is the foundation of a profitable mobile business.

The Complete Header Bidding Guide

Traditional waterfall mediation is failing modern publishers. By ranking ad networks in a fixed, predetermined order based on historical data, the waterfall model creates a structural revenue leak where higher-paying bidders are often ignored simply because of their rank. Header bidding solves this by flipping the auction model entirely, allowing all demand partners to bid simultaneously before the ad server is even called. Whether you are a hyper-casual game developer or a cross-platform creator using Flutter or Unity, understanding the technical nuances between client-side and server-side auctions is critical. While client-side offers transparency, server-side bidding is often preferred for mobile apps to reduce latency. By integrating header bidding into your ad mediation platform, you move away from managed queues toward a live, competitive market, ensuring you capture the true market value of every single impression.

The Best Mobile Ad Networks

Choosing the right mobile ad mediation platform is the single biggest lever for app revenue in 2025. While the global in-app advertising market heads toward $350 billion by 2026, professional studios are moving away from single-network setups toward hybrid mediation. This approach uses real-time bidding to force competition, often resulting in 40–100% ARPU uplifts. This guide covers the metrics that matter for independent developers: payout speeds, SDK support for frameworks like Unity, Godot, and Unreal, and why an independent mediation partner avoids conflicts of interest. Whether you are self-publishing on Google Play or managing a gaming studio, selecting a partner with verified A/B-tested results is the most reliable way to maximize eCPM without compromising user experience.

Ad Mediation for Unreal Engine

Building a high-performance mobile game in Unreal Engine is only half the battle; the real challenge lies in effective monetization. Ad mediation is the essential bridge between your game and dozens of global ad networks. Rather than relying on a single provider, mediation creates a live auction environment where networks compete in real-time to fill your ad slots, ensuring you receive the highest possible eCPM for every impression. For Unreal Engine developers, whose games often attract high-value, engaged audiences, mediation isn't just an option—it’s a revenue multiplier. By integrating a solution like CAS.ai, developers can access over 150 DSPs through a single SDK. This independent, programmatic approach removes network bias, leading to reported ARPU increases. With features like a "no-loss" A/B test guarantee and reduced crash rates, ad mediation allows you to focus on gameplay while maximizing your bottom line automatically.

What Is Ad Mediation for Unity Developers

For Unity developers, ad mediation is the essential technology layer that sits between your mobile game and dozens of global ad networks. Instead of relying on a single provider, mediation connects you to a vast marketplace, triggering real-time auctions for every impression. By polling multiple networks simultaneously, the system ensures the highest-paying ad is always served, significantly increasing your eCPM and fill rates. Modern platforms utilize programmatic bidding (or header bidding) alongside traditional waterfalls to create a competitive environment where 20 to 70+ networks bid for your inventory. For Unity creators, this eliminates single-network dependency and centralizes reporting into one dashboard. Whether you choose native solutions like Unity LevelPlay or high-performance independent options like CAS.AI, implementing a robust mediation strategy is the most effective way to automate growth and ensure you aren't leaving money on the table.

Ad Mediation: The Guide to Mobile App Monetization

Managing monetization network by network is a grind - multiple SDKs, scattered dashboards, constant eCPM tweaks, and missed revenue. Ad mediation, which manages ads across networks, solves this. With mediation, you get a single SDK and dashboard. Each ad request is sent to multiple networks, bids are compared in real time, and the highest-paying ad wins - no manual prioritization or stale data, just maximum value per impression. The result? Higher eCPMs, better fill rates, and far less operational overhead. Modern platforms combine real-time bidding and waterfall fallback, so every impression is monetized efficiently. Centralized analytics and automated optimization mean you’re scaling performance, not just reacting. Manual setups leave revenue on the table. Mediation isn’t just a tool - it’s the backbone of smart app monetization.

Programmatic Advertising for Mobile Apps: How It Works | CAS.AI

Programmatic advertising is the automated, real-time buying and selling of ad impressions through instant auctions. In mobile apps, this operates as in-app bidding directly inside the mediation SDK, where demand-side platforms bid simultaneously on every impression in milliseconds, ensuring the highest bidder wins. Unlike the older waterfall model, which calls networks sequentially and often leaves money on the table, programmatic auctions force all demand sources to compete at the same time. This maximizes revenue and drives higher eCPMs. However, publishers must navigate unique mobile constraints like privacy frameworks, alongside risks such as ad fraud and brand safety. Mitigating these risks requires publishing an app-ads.txt file and partnering with trusted mediation platforms that verify demand sources. By integrating a reliable mediation SDK, mobile publishers can seamlessly access global DSPs, optimize fill rates, and automate monetization with minimal ongoing maintenance.

How to advertise your app

Programmatic advertising is an automated, real-time auction that determines which ad wins each impression in a mobile app. Inside the mediation SDK, the ad request goes out to every connected network and DSP simultaneously, not one at a time. Each bidder returns a price in milliseconds, and the highest bid wins before the ad ever renders. This is what separates in-app bidding from the older waterfall model, where networks are called in a fixed sequence, and lower-priority demand never sees the best impressions. With programmatic, every impression goes to whoever values it most, which typically results in higher eCPM and less manual reordering. Mobile adds its own constraints SKAdNetwork, Privacy Sandbox, and device ID limits that make in-app bidding a distinct engineering problem, not a straight port of web header bidding. Publishers access it through mediation platforms like CAS.AI, which connect networks and DSPs into a single real-time auction.
