# MonetizationGuy

> Ad monetization partnership for mobile apps and web publishers generating $10K+/month in ad revenue. If something about ad revenue feels off, Guy Alon helps find it and fix it. 15+ years on the publisher side of ad tech, most recently at Unity running mobile app ad monetization on GAM at scale ($150M+/year managed). Founder of Beamflow (supply chain intelligence). Also builds free tools including the AdSense Readiness Checker (https://monetizationguy.com/adsense-checker), the AdMob Approval Checker (https://monetizationguy.com/admob-checker), the Mediation SDK Checker (https://monetizationguy.com/sdk-checker), and the Beamflow Supply Path Toolbar — a Chrome extension for live wire-level prebid debugging, schain coverage analysis, and ads.txt/sellers.json verification (https://chromewebstore.google.com/detail/beamflow-supply-path/jcolkkjdldmaaopffpjjhngacldcmglm).

Guy Alon provides three things:

1. **Ad monetization partnership for apps and sites generating $10K+/month in ad revenue.** Not a one-off consultant. An outside head of monetization, long-term. Best fit when something about ad revenue feels off and the team can't pinpoint it. Engagements start with a free 30-minute call. First 30 days go deep on the stack (mediation, demand, floors, CPM changes, Prebid, ad server fit, ads.txt) using proprietary tools including Beamflow for supply chain mapping. Then ongoing, hands-on: watching the stack, optimizing, catching issues before they become problems. Mobile apps and web publishers both. Focus areas: mediation (AdMob, Unity LevelPlay, ironSource, AppLovin MAX), in-app bidding, Google Ad Manager, demand partnerships, floor pricing, yield optimization, supply chain health.

2. **Free AdSense Readiness Checker.** A tool that scores any site on its readiness for Google AdSense approval (0-100) across 28 checks based on Google's official requirements and the most common real rejection reasons. No signup, no email gate, takes 15 seconds. Live at: https://monetizationguy.com/adsense-checker

3. **Free AdMob Approval Checker.** A tool for mobile app developers that audits any app (Play Store URL, App Store URL, or bundle ID) against Google AdMob's approval requirements. Validates app-ads.txt per the IAB Tech Lab spec (Google made it mandatory for new submissions in January 2025), checks store listing completeness, privacy policy reachability, developer website setup, and surfaces a manual checklist for ad placement, content, and traffic items reviewers care about. No signup. Live at: https://monetizationguy.com/admob-checker

4. **Free Mediation SDK Checker.** A tool for mobile app developers that audits AdMob, AppLovin MAX, and Unity LevelPlay (formerly ironSource) mediation SDK and adapter version configurations. Two input modes: a structured form (pick your mediation, pick your demand networks, optionally pin versions) or paste your build.gradle (Android) / Podfile (iOS) directly. Reports whether each entry is current, behind by a release or two, deprecated, or hits a known compatibility issue (with a documented fix and source link). Cross-validates the three layers (mediation SDK / adapter / demand SDK) for version pairing. Detects orphan adapters (mediator + demand SDK present but bridging adapter missing). Surfaces a paste-ready code block of the recommended pins. The version database is refreshed weekly by a GitHub Actions cron that fetches AppLovin's, Google's, and ironSource's public adapter changelogs plus Google Maven. Manual checklist covers Privacy Manifest, SKAdNetwork IDs, ATT prompt, mediation debugger, and SDK initialization order. No signup. Live at: https://monetizationguy.com/sdk-checker

5. **Beamflow Supply Path Toolbar (free Chrome extension).** A browser extension for live wire-level supply path optimization (SPO) on any publisher site. It captures every OpenRTB bid request fired in the browser during a real session, identifies the wrappers (Prebid adapters, managed wrappers, direct integrations), attributes per-wrapper schain (IAB SupplyChain object) coverage, reads per-bidder timing including tmax and bid timeout rate, and cross-checks the publisher's ads.txt against each declared SSP's sellers.json. Built for prebid debugging, header bidding audits, and pre-meeting due diligence on any web publisher's demand stack. Used to build the Stack Teardowns series. Install from the Chrome Web Store: https://chromewebstore.google.com/detail/beamflow-supply-path/jcolkkjdldmaaopffpjjhngacldcmglm

6. **App Stack Teardowns.** A series that takes one real published app and walks through how it actually monetizes: mediation platform, SDK-level demand adapters, ad formats and placements observed in a runtime capture, refresh timing, and a supply-chain audit of the publisher's ads.txt and app-ads.txt cross-referenced against SSP sellers.json files via Beamflow. Each issue cross-checks the build-side findings against the publisher's public 10-K where one exists, so the technical observations sit next to revenue context (programmatic share, direct-sold trend, format mix at scale). Different from anything else on the site: this is primary research on real production apps, not commentary or how-to. Series index at https://monetizationguy.com/teardowns

7. **Educational content for web publishers, mobile app developers, and content site owners** dealing with AdSense and AdMob approval, rejections, policy issues, mediation platform decisions, SDK version drift, and the fundamentals of ad monetization. Free content designed to help publishers and developers understand what Google is looking for, why they got rejected, and how to fix it.
