Share your approach in the comments and subscribe for future deep dives tailored to your product.

Know Your Ad Formats and Their Purpose

Rewarded video works best when the benefit is fair, clear, and immediate. Prefetch creatives, guard against failed rewards, and place it where motivation is strong. Ask users what they value most, then tune the reward size. Tell us your best‑performing reward structure and why it resonates.

Target calm moments—after achievements, save actions, or completed tasks. A puzzle app moved an interstitial from mid‑level to the summary screen and saw session length grow without revenue loss. Micro‑delays for prefetching help. Try it and comment with your before‑and‑after observations.

Placement and Frequency That Respect UX

Targeting, Privacy, and Consent Done Right

Use concise language, a clear value proposition, and accessible design. For iOS, warm up the ATT prompt with a helpful pre‑permission screen. Test copy, order of options, and visuals. Track opt‑in by cohort and journey stage. What uplift have you seen from better consent copywriting?

Targeting, Privacy, and Consent Done Right

Leverage privacy‑safe context: device class, connection quality, time of day, on‑screen content type, and in‑app behavior events. These signals help mediation route demand without personal identifiers. Start simple, log results, and iterate. If contextual targeting lifted eCPM for you, share your strongest signal.

Creative Strategy and Testing for Real Results

Hypothesis‑driven A/B tests

Write a crisp hypothesis, define primary metrics, and estimate sample size up front. Use sequential testing or fixed horizons to avoid p‑hacking. Monitor spillover effects on retention, crashes, and ratings. What’s your favorite success metric for creative tests—IVR, eCPM, ARPDAU, or something else?

Short‑form video and playables

Short videos (6–15 seconds) and playables convert well when they respect audio‑off defaults and teach one clear benefit. Consider a reward follow‑up that nudges completion. An indie team added a tiny tutorial overlay and cut early exits. Share your best creative tweak that surprised you.

Localization and cultural nuance

Adapt visuals, idioms, currencies, and calls to action by region. Celebrate local holidays and avoid imagery that reads negatively in specific cultures. Test font legibility and color contrast. Consistency matters. Subscribe and send examples from your market—we’ll feature standout localized creatives.

Floor prices and demand diversity

Set dynamic floors per geo and format, revisiting weekly with sufficient data. Avoid dependence on a single network and cultivate a healthy long tail. Rotate underperformers out. Comment with the geo where floors moved your revenue needle most and how you validated the change.

Hybrid setups you can maintain

Lead with top‑tier bidders, then a trimmed instance waterfall ordered by recent eCPM and reliability. Prioritize only the complexity you can actually support. Automate syncs and sanity checks. What’s your current stack shape, and which change delivered the clearest performance lift?

Measure What Matters: KPIs and Incrementality

Start with ARPDAU, eCPM, fill rate, and IVR, but tie them to retention curves and crash rates. Review trends weekly with product and ads teams together. Make tradeoffs explicit. What metric did you intentionally improve last sprint, and what cost did you accept to get there?

Measure What Matters: KPIs and Incrementality

Compare ad‑exposed cohorts against controls to reveal behavioral shifts. Inspect funnels: where do viewers churn, and which rewards drive repeat engagement? Look for journey friction, not just revenue spikes. Share a cohort insight that changed your placement strategy, and help others learn faster.

Operational Excellence and Creative Hygiene

SDK hygiene and crash prevention

Keep a predictable upgrade cadence, test on a diverse device matrix, and use feature flags to isolate changes. Track ANR, memory, and cold start impacts for each update. Share your release checklist and subscribe to get ours—lightweight, developer‑approved, and battle‑tested across multiple stacks.

Detecting and blocking bad creatives

Implement category blocking, maintain a creative review channel, and escalate quickly with network partners. Protect kid‑safe experiences with strict filters and default‑off categories. Monitor user reports and complaint keywords. What safeguards saved your ratings recently? Tell the story to help others avoid pitfalls.

Rituals that keep everyone aligned

Run a weekly monetization review: top movers, experiments, creative learnings, and open risks. Set sprint goals visible to product, growth, and engineering. Celebrate small wins to reinforce the culture. Add your team’s favorite ritual in the comments, and subscribe for templates you can copy.
