CAS.AI mobile publishing: KPIs, UA testing, monetization, in-app purchase

CAS.AI Method in Action: Reliable, Scalable Mobile Publishing

October 17, 2025 6 min read

At CAS.AI we do mobile publishing the pragmatic way—clear KPI gates, Tenjin-powered analytics, and ILD monetization—so we’re scaling apps efficiently, not blindly. Start small, validate, then grow what works.

Who We Are

PSV games started in Ukraine and moved its headquarters to Cyprus in 2014. Today we operate two offices in Cyprus and one in Ukraine, with a 150-person distributed team. Our portfolio includes roughly 500 apps: about 300 kids’ games (including our own Hippo brand and licensed IP like Masha and the Bear, LOL, etc.) and around 100 non-kids titles. Actively, we run UA for ~100 apps, with 40–45 of them receiving major acquisition scale at any time.

From Mediation to Mobile Publishing

We initially built our own monetization stack and mediation (“CAS.AI”), then partners asked for help with UA because monetization performance was strong. This is how our publishing arm was born about 18 months ago. We now publish and scale UA for roughly 20 external studios, supporting marketing, UA, and monetization end-to-end.

How We Evaluate New Games

Before committing to scale, we review in-game metrics and run a small paid UA test. We primarily focus on hyper-casual and casual genres. Our baseline acceptance thresholds:

  • Retention. D0 (Day 0): ≥ 20% • D7: ~5–7% • D30: ~2–3% (higher is better).
  • Playtime / session length. Casual & hyper-casual: 7–10 minutes per session is a solid starting point.
  • Ad load & formats. Ad-only games: ~5–7 ad impressions per user/day. If mostly interstitials: target ~7/day. If interstitial + rewarded mix: ~5–7/day total (e.g., ~5 interstitials + 2 rewarded, adjusted via tests). Banners can lift LTV ~10%, but watch UX: they often bother users unless placed carefully.

Recommendation for studios: Set genre-specific guardrails, not absolutes. Use these benchmarks to decide “go/no-go” after a small test, then tune per cohort (geo/device/channel).

UA Testing for Mobile Publishing Scale

We start with small budgets—typically $150–$200 per channel—to validate economics before scaling. Historically we began with Google Ads + Firebase, but today we diversify channels. Example: a recent Mintegral test passed our KPI, so we scaled spend and added sources.

A typical early KPI might be D0 ROAS ≥ 67% (illustrative; varies by genre/country). If ad-mediation revenue on D0 exceeds the KPI threshold, we greenlight scaling and broaden channels.

Recommendation for studios: Define a per-genre D0/D1/D7 ROAS template (and margin of error). If a channel beats your target with stable retention and CPMs, promote it to your “always-on” set.

Monetization Stack and Impression-Level Data (ILD)

We operate our monetization via CAS.AI mediation and collect impression-level revenue data (ILD). For every ad impression, we know the network, placement, format, and revenue. This feeds our dashboards and lets us see which combinations of network × geo × format × placement drive profitable scale.

  • Ad-first games: start with interstitial + rewarded; add banners only with no UI overlap and good viewability.
  • Hybrid games: lead with rewarded, add native/immersive where you can provide 2+ seconds of safe on-screen time, and place interstitials only at clean milestones.

Recommendation for studios: Treat ILD as a must-have. It’s the fastest way to spot dying placements, underperforming networks, or geos with inefficient CPMs.

Analytics: Tenjin as the MMP and Data Backbone

  • Attribution + MMP basics (our single source of truth for UA).
  • Raw Data + DataVault access for analytics engineering.
  • Custom dashboards by game/platform/geo/channel/campaign.
  • Cohort breakdowns for ROAS, retention, LTV, CPM/eCPM, CTR/CR by country, device, source, and creative.

We import historical data (last 30/90/120 days) to analyze behavior and forecast LTV. Then we align creative and channel strategy with the best-performing cohorts.

Learn more about our analytics approach in thisTenjin × CAS.AI interview with our CMO , where we discuss DataVault usage, ILD workflows, and ROAS tracking in practice.

Recommendation for studios: Start with an MMP that gives you raw data. Let your analytics team own a single self-serve dashboard with the exact cuts UA managers need (channel × geo × D0/D7 ROAS, retention, CPI, eCPM).

Reporting, Access, and Collaboration

Internally, different teams (UA, analytics, monetization) receive role-based access (e.g., admin for analytics to build dashboards, read raw data). For publishing partners, we grant scoped access—they can see only their own apps and create reports. This transparency speeds up joint decision-making without exposing unrelated portfolios.

Recommendation for studios: Implement RBAC and per-app scoping for partners. Transparency builds trust; isolation protects data.

Example Outcome (What “Pass” Looks Like)

  • Early test on a new network meets/exceeds D0 KPI (e.g., ≥67% ROAS).
  • Ad mediation shows higher-than-target D0 revenue per user.
  • Retention and session length hold under added ad load.

Decision: scale spend, add more channels, iterate creatives, and retest geos with best early CPMs.

What Other Studios Can Apply (Actionable Takeaways)

  • Define acceptance KPIs per genre — use D0/D7/D30 retention and D0 ROAS guardrails to decide “test → scale” quickly.
  • Start small; prove unit economics — $150–$200/channel is enough to validate before you ramp.
  • Ad mix by design. Hyper-casual: 5–7 impressions/day total; interstitials at clean breaks; rewarded for boosts; banners only if they don’t harm UX. Hybrid: lead with rewarded + native/immersive; interstitials only at milestones.
  • Collect impression-level data (ILD) — prune weak placements, negotiate floors, and tune waterfall/bidding strategy.
  • Use an MMP with raw data — Tenjin (or similar) + a central dashboard by geo × channel × campaign accelerates decisions.
  • Segment by geo from day one — your D0 KPI in Tier-1 vs Tier-3 will differ. Don’t average them.
  • Respect UX — banners can add ~10% LTV only if they avoid UI overlap and accidental clicks.
  • Scale only what passes — if a channel beats your KPI and retention holds, move it to “always-on.” If it slips, pause and triage.

Closing: CAS.AI’s Way of Mobile Publishing and Scaling Apps

CAS.AI evolved from a kids-games studio to a global publishing and mediation platform by standardizing acceptance KPIs, testing UA in small, data-driven steps, running ad monetization on ILD, and building analytics on reliable MMP data. If you’re a studio looking to publish or to scale UA/monetization, adopt these practices—then iterate relentlessly.

Ad Mediation for Godot

Ad mediation is the essential middleman between your mobile game and multiple ad networks, ensuring you never leave money on the table. Instead of relying on a single provider like AdMob, mediation triggers a real-time auction for every ad slot, allowing the highest bidder to win the impression. For Godot developers, this technology is a game-changer. By implementing a mediation layer, you can navigate the engine's unique SDK landscape while accessing high-paying formats like rewarded videos and interstitials. Platforms like CAS.ai streamline this process by connecting your project to over 20 networks and 150 DSPs through a single integration. This setup eliminates the "empty slot" problem, stabilizes revenue during seasonal shifts, and provides unified analytics. Whether you are building hyper-casual titles or complex midcore games, ad mediation can boost your total revenue by 30% to 60%, making it a non-negotiable tool for any serious mobile developer.

The Best Mobile Ad Networks

hoosing the right mobile ad mediation platform is the single biggest lever for app revenue in 2025. This guide compares top industry leaders—CAS.AI, AdMob, AppLovin MAX, and Appodeal—across performance metrics essential for independent developers. 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. The comparison highlights CAS.AI’s independent model and "no-loss guarantee" against the giant ecosystems of Google-owned AdMob and AppLovin MAX. Key factors include payout speeds (ranging from 5 to 21 days), SDK support for frameworks like Unity, Godot, and Unreal, and the critical importance of avoiding conflicts of interest. Whether you are self-publishing on Google Play or managing a gaming studio, selecting an independent partner with verified A/B-tested results is the most reliable way to maximize eCPM without compromising user experience.

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.

Beyond Gaming: How Non-Gaming Apps Are Rewriting the Mobile Monetization Playbook

Non-gaming apps are set to out-earn games in 2025: $85.6 billion versus $81.8 billion. But if you’re leaving most users unmonetized, the headline is irrelevant. Most non-gaming apps blow it in three main ways: They obsess over subscriptions, which only convert 2-5% of users; run lazy, single-format ad stacks; and cling to the myth that better monetization ruins the user experience. It doesn’t. Combine ads and subscriptions. Watch lifetime value jump over 50%. Users who hit rewarded video are 4.5 times more likely to pay. Clearly, the formats work. Hybrid models work. The blueprint is already out there. Gaming has already paid the price to figure this out. Skip the mistakes: start adopting hybrid monetization strategies now to close the gap.

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.
