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.

Creative at the Speed of AI

By Q3 2026, AI-generated creative isn’t an experiment; it’s the default production method for most UA teams. But that shift created a new bottleneck: not making variants, but deciding what to do with them. Ad accounts that once ran 5-8 creatives now cycle through 30-50, and no human reviewer can keep up with that volume. Studios are pulling ahead, automating not just generation but the decision layer. Their systems flag CTR decay, frequency saturation, and CPM drift before dashboards catch up, then automatically rotate and regenerate creatives. Most teams optimize for install volume because it’s easy to track, but it’s the wrong metric. A creative can win on CPI and still fail on retention and revenue. The real gap is whether studios connect creative performance to downstream monetization, not just installs. Mediation-layer transparency becomes a creative-testing tool, not just a finance metric.

ASO in 2026: How to Make Sure Users Can Actually Find Your App Page

ASO isn’t a launch-day checkbox. It’s a feedback loop. If you skip the update cycle, your rankings slip and competitors pass you. This checklist cuts through the noise and shows what actually drives organic installs in 2026: build separate keyword structures for iOS and Android (copy-pasting is lazy and costs you installs), rebuild your semantic core every 2-4 weeks, and run visual tests that isolate a single variable so your data is actionable. You’ll get the real rules: why the first three screenshots on iOS make or break your conversion, how literal translation kills your numbers in new markets, and the only four A/B tests that matter when you start: icon style, hero screenshot message, color themes, and video vs. static. The 2026 AI stack is here: keyword tracking, competitor moves, creative testing, and review monitoring so you’re not stuck in spreadsheets. Five mistakes still tank rankings, even if your keywords look perfect.

ASO and paid user acquisition have merged into a single growth system as store algorithms focus on product quality, Apple expands ad placements, and organic-only strategies lose ground inside the competitive app economy of 2025. Mobile marketing entered 2025 at a crossroads. The rules that governed app growth for years - organic optimization here, paid acquisition there - no longer hold. Apple Search Ads rolled out new placements, user behavior shifted in unexpected ways, and competition intensified across every category. The result? ASO stopped being a standalone discipline practiced in isolation and became inseparable from the entire product and marketing funnel.

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.

App Monetization Guide

Making money from an app is not as simple as flipping a switch. You need a whole toolkit. Ads, in-app purchases, subscriptions, and mixing them together all come with their own twists. What actually works depends on your app and the people using it. This guide walks you through every model that is actually worth your time. I will show you how in-app ads and mediation work in practice, where in-app purchases and subscriptions fit in, and why hybrid monetization is taking over in 2026. You will see how to choose a strategy based on your app, your platform, and your region. I will also break down the five metrics that really matter and the common mistakes that quietly put a lid on revenue for most teams. Let us look at some real numbers. One CAS.AI publisher, Fail Games, saw their revenue jump by about 80 times after it switched to a hybrid setup with both ads and in-app purchases, using mediation to manage the ads. Another publisher went from making just four dollars a day to eighteen thousand euros a month, simply by adding mediation. Here is how they did it.
