Bundle Insights are crucial for advertisers and app developers navigating the ever-evolving mobile landscape.
In this article, we will explore the April 2025 rankings of the Top 100 Bundle IDs for mobile apps in North America, focusing on open programmatic advertising volume.
We will evaluate how invalid traffic (IVT) impacts these rankings, providing valuable performance insights that help stakeholders understand market trends and improve ad quality.
By analyzing these trends, advertisers can strategically enhance their campaigns, ensuring they stay ahead in a competitive market.
Overview of Pixalate’s April 2025 Top 100 Bundle ID Report
A bundle ID is a unique identifier tied to a specific mobile app, acting as a digital fingerprint that distinguishes one app from another across iOS and Android platforms.
More than just a technical tag, bundle IDs allow platforms and ad exchanges to track advertising volumes, user engagement, and even detect suspicious traffic.
Because these identifiers play a foundational role in digital ad targeting and tracking, understanding which apps drive the most ad traffic is critical.
That’s why Pixalate’s rankings matter—not only do they reflect which apps dominate programmatic advertising, but they also provide visibility into ad quality by adjusting for invalid traffic (IVT).
As a result, developers, marketers, and programmatic buyers can benchmark success and refine monetization strategies.
At its core, the rankings help cut through noise and identify which apps sustain both scale and trust in the ecosystem, demonstrating Pixalate’s position as a market standard.
Also Compiled from open programmatic advertising data, this report focuses on North America throughout April 2025.
In addition Pixalate analyzed programmatic ad traffic volume from thousands of apps and adjusted for IVT to better represent legitimate ad impressions.
This approach delivers clearer performance insights while reducing the influence of ad fraud.
For app developers, the insight reveals how app activity relates to advertiser demand.
In conclusion For advertisers and marketers, it helps allocate spend efficiently by showing which channels are safest and most trafficked.
Below is a simplified view of three core criteria Pixalate used to rank bundle IDs:
| Criterion | Example |
|---|---|
| Download Volume | 10 M+ |
| Invalid Traffic Rate (IVT) | 3.1% |
| Ad Requests | 5 B+ |
Evaluating Open Programmatic Advertising Volume
Open programmatic advertising refers to the transparent, automated buying and selling of digital ad inventory across a wide range of supply sources without predetermined deals or commitments.
Also Pixalate evaluates open programmatic volume by analyzing measurable signals from real-time bidding environments, focusing closely on supply-side activity tied to bundle IDs to understand trends within mobile app ecosystems.
This assessment incorporates billions of daily impressions, filtering volumes through metrics such as geographic origin, platform type, and invalid traffic (IVT) rates, which helps quantify true advertiser value.
According to Pixalate’s North America April 2025 Mobile Rankings, volumes shifted significantly compared to March.
While March saw a heavier surge in lifestyle and gaming categories, April’s open programmatic volume grew modestly by 4% overall, but several top-ranked apps recorded individual declines of up to 12% following IVT adjustments.
Pixalate’s methodology isolates legitimate impressions from fraudulent or manipulated traffic, prioritizing accuracy in its ranking system.
Advertisers benefit from these insights by aligning their strategies with high-performing, trustworthy apps.
Meanwhile, developers gain transparency about their app monetization strengths in a heavily scrutinized programmatic market where both quality and volume directly influence brand investment decisions.
The Role of Invalid Traffic in Ranking Integrity – Bundle Insights
Invalid traffic refers to any activity that does not originate from a real user with genuine interest in the content or offer, often disrupting the accuracy and value of digital advertising metrics.
It includes a range of fraudulent or unnatural behaviors that distort ad performance and can lead to significant financial loss for advertisers.
Examples of relevant types of invalid traffic include:
- Bot-generated requests
- Click farms or incentivized clicks
- App spoofing and misrepresentation
Pixalate utilizes sophisticated detection tools that leverage machine learning, pattern recognition, and behavioral analytics to identify and filter invalid traffic across mobile and CTV ecosystems.
Their rankings, such as the Top 100 Mobile Bundle IDs for April 2025, are calculated only after removing IVT, ensuring a more accurate reflection of app inventory quality.
According to the latest benchmarking by Pixalate, the United States saw a 26% mobile app IVT rate in Q1 2025, reinforcing the urgency of fraud prevention strategies.
By separating human traffic from fraudulent sources, Pixalate offers a cleaner, more reliable view of the mobile advertising landscape in North America
Filtering invalid traffic is not optional—it is essential for maintaining ranking integrity and protecting advertiser investments

Market Trends and Ad Quality Insights
As of April 2025, Pixalate’s Top 100 bundle ID rankings for mobile apps in North America reveal increased dominance of word games and casual puzzle apps within open programmatic advertising markets.
Titles like Wordscapes and Scrabble GO dominate share across the Apple App Store and Google Play, reflecting the sustained popularity of low-friction, high-retention content.
At the same time, lifestyle and entertainment apps are showing signs of stabilization after Q1 volatility, suggesting a maturing audience and more efficient monetization strategies evolving post-pandemic.
Key to this ranking is not just impression volume, but also the quality of those impressions, especially as advertisers shift from pure scale to more verifiable performance.
Ad quality, as defined by Pixalate, encompasses the authenticity of traffic, reliability of impressions, and resistance to invalid traffic (IVT).
The firm measures these using signals from over 20 billion impressions across mobile platforms.
In Q1 2025, mobile app IVT in the United States hovered near 26%, demanding accountability in how bundle IDs are monetized according to Pixalate’s North America IVT Benchmark Report.
As advertisers invest more in quality-driven targeting, developers must adapt by emphasizing IVT-minimized environments to sustain app monetization
Looking ahead, the interplay of reliable ad traffic and category-specific user retention will likely reshape budget allocation, incentivizing apps that prioritize both engagement and trust.
Bundle Insights from the April 2025 rankings reveal key trends that can guide advertisers and developers.
By understanding the dynamics of programmatic advertising and the influence of IVT, stakeholders can make informed decisions to optimize ad performance and quality.
