AppHarbr by GeoEdge Launches the First Index Ranking In-App Ad Networks on Ad Quality & Safety

Why It Matters

The index gives publishers a measurable way to assess ad safety beyond eCPM, reducing revenue‑draining malvertising and user‑experience risks. It signals a market shift toward accountability and higher‑quality ad demand sources.

Key Takeaways

• 50% ad networks failed baseline safety standards.
• iOS apps see three times more malicious ads than Android.
• All networks violated ad‑skippability, extending ads up to 80 seconds.
• Meta leads ad safety in gaming apps, followed by AppLovin.
• Header‑bidding SDKs correlate with higher ad‑quality performance.

Pulse Analysis

Mobile advertising revenue continues to grow, but the surge in intrusive and malicious creatives has eroded user trust. AppHarbr’s new Index provides the first data‑driven snapshot of how ad networks perform on safety, user experience, and compliance, using real in‑app traffic rather than self‑reported claims. By analyzing 25 billion ads across 500 apps, the report uncovers systemic weaknesses that traditional metrics like eCPM overlook, highlighting the need for publishers to prioritize quality as a core KPI.

The findings reveal stark disparities: 50 % of global ad networks fail baseline safety standards, and iOS environments suffer nearly three times the malicious ad exposure of Android. Moreover, ad‑skippability standards are universally breached, with many ads stretching from the promised 15‑30 seconds to 60‑80 seconds, inflating user frustration and churn. For monetisation teams, these insights shift the evaluation framework toward safety‑adjusted eCPM, where the cost of poor‑quality ads—lost users, brand damage, and increased support costs—must be factored into revenue calculations.

Strategically, the Index spotlights leaders such as Meta, AppLovin, and ironSource in gaming, and Meta, The Trade Desk, and TripleLift across broader apps, indicating that networks leveraging header‑bidding SDKs tend to deliver cleaner inventories. Publishers can use this data to renegotiate contracts, adopt stricter mediation layers, and integrate real‑time monitoring tools like AppHarbr’s platform. As the industry leans into transparent, safety‑first ad ecosystems, early adopters of quality‑centric measurement will likely capture higher user retention and premium ad rates.
