In the mobile landscape of 2024, the most effective ad networks for monetization and user acquisition were Google AdMob, AppLovin (MAX), Unity LevelPlay (formerly ironSource), Meta Audience Network, and Liftoff (Vungle). These platforms led the industry by offering superior real-time bidding (RTB) technology, high global fill rates, and advanced creative optimization tools that successfully navigated the evolving privacy constraints of the era.
The Evolution of Mobile Advertising in 2024
As we look back from 2026, the year 2024 stands out as a pivotal moment for the mobile advertising ecosystem. It was a year characterized by the definitive shift away from traditional "waterfall" mediation toward unified, programmatic bidding. This transition was driven by a need for transparency, reduced latency, and higher yields for developers who were feeling the pressure of a saturated app market.
The mobile ad networks that rose to the top in 2024 did so by addressing the two most significant challenges of the time: the deprecation of traditional identifiers like IDFA and the increasing demand for high-quality, non-intrusive ad experiences. Developers no longer looked for just "any" ad network; they sought partners that could provide granular data insights while maintaining compliance with international privacy regulations.
Successful networks in 2024 focused on AI-driven optimization. By leveraging machine learning models, these platforms could predict user behavior and value even with limited deterministic data. This enabled them to maintain high eCPMs (effective cost per mille) for publishers and high ROAS (return on ad spend) for advertisers, solidifying their positions as the "Big Five" of the year.
1. Google AdMob: The Global Standard for Scale
Google AdMob remained the undisputed leader in 2024 for both independent developers and large-scale enterprises. Its primary advantage stemmed from its integration with the broader Google Ads ecosystem, providing access to an unparalleled pool of global advertisers.
Comprehensive Ad Formats and Integration
In 2024, AdMob excelled by offering a highly versatile range of ad formats. This included standard banners and interstitials, but the real growth was seen in Native Ads Advanced and Rewarded Interstitials. Native ads allowed developers to match the look and feel of their app’s UI, leading to higher engagement rates and a less disruptive user experience.
The integration with Firebase, Google’s mobile development platform, provided developers with a seamless transition from app building to monetization. By using Firebase’s analytics, publishers could segment their audience in real-time, serving different ad frequencies or formats based on user value—a strategy that became standard practice throughout 2024.
Real-Time Bidding and Open Bidding
AdMob’s "Open Bidding" technology was a cornerstone of its 2024 success. By allowing multiple ad sources to bid on ad inventory simultaneously in a fair, real-time auction, AdMob ensured that the highest-paying ad always filled the slot. This reduced the operational overhead associated with managing complex waterfalls and significantly boosted the "Average Revenue Per Daily Active User" (ARPDAU) for mobile publishers.
2. AppLovin (MAX): The Performance Powerhouse
By 2024, AppLovin had transitioned from a high-growth network into a dominant infrastructure provider, primarily through its MAX mediation platform. After the full integration of MoPub’s assets in previous years, MAX became the preferred choice for publishers focused on hyper-casual and mid-core gaming.
The AXON 2 AI Engine
The true differentiator for AppLovin in 2024 was its proprietary AI engine, AXON 2. This machine learning technology was designed to better match advertisers with relevant users. For advertisers, this meant significantly more efficient user acquisition (UA) campaigns. For publishers, it resulted in higher conversion rates on ads shown within their apps, which naturally drove up eCPMs.
MAX Mediation Dominance
AppLovin MAX pioneered the "Header Bidding" style of mobile mediation. In 2024, its dashboard was widely regarded as the most user-friendly for A/B testing different monetization strategies. Developers could test different "price floors" or ad placements with a single click, allowing them to optimize their revenue based on real-time data rather than historical averages. This level of control made AppLovin an essential partner for developers aiming to maximize their bottom line.
3. Unity LevelPlay: The Premier Choice for Game Developers
Following the merger with ironSource, Unity LevelPlay emerged as the leading specialized network for the gaming industry in 2024. Despite the challenges faced by the Unity engine itself during that period, the LevelPlay mediation platform remained a gold standard for game monetization.
Gaming-First Optimization
Unity LevelPlay was built with the specific needs of game developers in mind. In 2024, its strength lay in Rewarded Video ads—ads that users choose to watch in exchange for in-game currency or items. Because Unity had deep visibility into game engine telemetry, LevelPlay could optimize ad timing to ensure it didn't interfere with the "game loop," thereby preserving user retention while maximizing revenue.
Advanced Analytics and the "Sonic" Suite
The ironSource legacy brought sophisticated growth tools to the Unity ecosystem. The Sonic suite allowed developers to manage the entire lifecycle of a game, from prototype testing to global launch and long-term monetization. In 2024, Unity LevelPlay’s "Ad Quality" tool was particularly influential, giving publishers the ability to see exactly which ads were being shown in their games and block any that were low-quality or off-brand.
4. Meta Audience Network: Leveraging Social Intelligence
In 2024, the Meta Audience Network (MAN) continued to be a top-tier choice for developers looking to monetize high-quality traffic, particularly on Android. Despite the limitations imposed by Apple's App Tracking Transparency (ATT), Meta’s deep understanding of user interests across Facebook and Instagram remained a powerful asset.
Precision Targeting in a Privacy-First World
Meta’s strength has always been its data. In 2024, the network utilized Contextual Advertising and aggregated data models to maintain targeting efficiency. Advertisers on MAN were able to reach specific demographics with high precision, which meant that the ads served were generally more relevant to the user than those from more "blind" networks. This relevance translated directly into higher click-through rates (CTR).
Focus on Native and Interstitial Ads
Meta Audience Network specialized in "Native" ad formats that felt like a natural extension of the social media experience. In 2024, many non-gaming apps (such as utility, news, and lifestyle apps) preferred Meta because its ads were aesthetically superior and often had higher production values. The network’s transition to a bidding-only model in early 2024 simplified the technical implementation for developers, requiring them to use mediation partners like MAX or AdMob to access Meta’s premium demand.
5. Liftoff (Vungle): The Creative and Performance Leader
Liftoff, which integrated the Vungle network, solidified its place among the top five in 2024 by focusing on the "creative" side of mobile advertising. While other networks focused on the plumbing of the auction, Liftoff focused on what the user actually saw.
Creative Optimization and Playable Ads
Liftoff was a pioneer in Playable Ads and high-definition video in 2024. Their in-house creative labs helped advertisers build interactive ad units that allowed users to "try before they buy" (or download). These interactive units were highly sought after by publishers because they offered the highest engagement rates in the industry. For a developer in 2024, having Liftoff in their mediation stack was often the key to unlocking premium "Brand" advertising dollars that were otherwise inaccessible.
Global Reach in Emerging Markets
While AdMob dominated the general market, Liftoff made significant inroads into emerging markets during 2024, particularly in Southeast Asia and Latin America. Their localized ad serving and expertise in regional performance trends made them an essential partner for developers looking for a truly global monetization strategy. Their ability to deliver high fill rates in Tier 2 and Tier 3 countries was a major factor in their 2024 success.

Technical Considerations for 2024 Implementations
When implementing these networks in 2024, developers had to adhere to several technical prerequisites to ensure maximum performance and compliance.
The Rise of SKAdNetwork 4.0 and 5.0
In 2024, Apple’s SKAdNetwork (SKAN) was the primary method for measuring ad performance on iOS. The top networks all updated their SDKs to support SKAN 4.0 and the emerging SKAN 5.0, which allowed for better attribution of re-engaged users. Developers who failed to update their network SDKs saw a significant drop in reported performance, leading to lower bids from advertisers.
SDK Orchestration and Size
A major concern in 2024 was "SDK Bloat." Adding five different networks could significantly increase an app’s file size, potentially deterring downloads. The industry solved this through Mediation Adapters. Instead of fully integrating every network's heavy SDK, developers used a primary mediation SDK (like MAX or AdMob) and added "lightweight" adapters for the other networks. This kept the app's footprint small while still allowing for a competitive bidding environment.
Data Privacy and Consent Management
The year 2024 saw stricter enforcement of the General Data Protection Regulation (GDPR) in Europe and the California Consumer Privacy Act (CCPA). All five top networks required the implementation of a Consent Management Platform (CMP). Without a verified CMP, these networks would often serve non-personalized ads (which pay significantly less) or refuse to serve ads entirely in certain jurisdictions.
Choosing the Right Network for Your Strategy
Selecting from the top five networks in 2024 wasn't about finding the "single best" one, but rather about building the most effective Mediation Stack. Most successful publishers used a combination of at least three of these networks to ensure 100% fill rates and competitive pricing.
- For maximum global fill: Start with Google AdMob. It is the most reliable "safety net" for unfilled inventory.
- For maximum gaming revenue: Prioritize AppLovin and Unity LevelPlay. Their bidding environments are specifically tuned for gaming audiences.
- For high-quality user experience: Integrate Meta Audience Network. Their native ad templates are generally the most aesthetically pleasing and least likely to cause user churn.
- For high-conversion UA: Use Liftoff. Their focus on interactive and playable creatives results in users with higher long-term value (LTV).
Frequently Asked Questions
Which mobile ad network had the highest eCPMs in 2024?
Generally, the Meta Audience Network and AppLovin often reported the highest eCPMs for rewarded video and interstitial ads in 2024. However, eCPM is highly dependent on the app's geographic audience and user retention metrics. Google AdMob typically offered the most consistent eCPMs across a wide variety of "Tier 2" and "Tier 3" countries.
Is it better to use a single ad network or a mediation platform?
In 2024, using a mediation platform (like MAX, AdMob, or LevelPlay) was the standard recommendation. Mediation allows multiple networks to compete for your ad space, which almost always results in higher revenue than using a single network exclusively. It also provides a single dashboard for managing all your ad partners.
How did privacy changes affect these networks in 2024?
Privacy changes, specifically Apple’s ATT and Google’s Privacy Sandbox for Android, forced networks to move away from individual user tracking toward probabilistic modeling and contextual targeting. The networks that stayed on top in 2024 were those that invested most heavily in AI to predict user value without needing a permanent device ID.
What was the most popular ad format in 2024?
Rewarded Video remained the most popular and highest-earning format for games. For non-gaming apps, Native Ads saw the most growth because they allowed for monetization without degrading the professional look of the application.
Do I need a separate SDK for every network?
No. While you need the "adapter" for each network, you typically only interact with the primary Mediation SDK in your code. This simplifies the development process and makes it easier to update your monetization strategy without releasing a new version of your app every time you add a partner.
Recommendation for Moving Forward
To succeed in mobile monetization based on the standards set in 2024, you should begin by integrating Google AdMob and AppLovin MAX as your foundational mediation layer. This combination provides the broadest reach and the most sophisticated bidding technology. Once your baseline is established, perform an A/B test by adding Unity LevelPlay if you are in the gaming space, or Meta Audience Network if you have a lifestyle or utility app. Continuous testing of your "ad floors" and format placements is the only way to ensure you are not leaving revenue on the table.
