Introduction
Unlocking AdX via the Multiple Customer Management (MCM) program is a game-changer for publishers ready to level up revenue. In this guide, we demystify the process, set clear expectations, and equip you to sail smoothly from application to activation.
What Is AdX MCM and Why It Matters
- AdX MCM in a nutshell: Google’s way to grant qualifying partners (like ATGP) access to AdX inventory and controls on behalf of publishers.
- Publisher benefits: Premium demand, transparent reporting, and granular pricing controls.
Step-by-Step Onboarding Roadmap
- Eligibility Check
- Minimum monthly impressions (e.g., 50 million)
- Clean policy compliance (ad quality, content guidelines)
- Contract Negotiation
- Define revenue share, payment terms, SLA guarantees
- Get legal sign-off on MCM Agreement
- Technical Setup
- Whitelist domains in your ATGP partner console
- Generate and deploy GAM tags or GPT code snippets
- Verification & QA
- Test fill rates in staging, check for errors in the console
- Review latency impact and viewability benchmarks
- Go-Live & Monitoring
- Soft launch on 10–20% of traffic
- Weekly pulse checks on RPMs, CTRs, and coverage
Common Pitfalls—and How to Avoid Them
- Incomplete tagging: Use GTM or a centralized tag library to prevent missing slots.
- Policy hiccups: Run a pre-launch scan for disallowed content to avoid suspensions.
- Overly aggressive floor prices: Start conservative, then iterate based on real-time bid data.
