What It Checks
DUPLICATE KEY DETECTION
Finds duplicate keys at every layer — top-level params, per-slot prev_scp, and cust_params. The exact issue that silently kills render rates.
VAST PARAMETER AUDIT
Validates all required and recommended VAST params against Google's official spec — env, vpmute, vpa, plcmt, description_url, output, and more.
HEADER BIDDING ANALYSIS
Breaks down active bidders per slot, flags missing HB keys, and identifies configuration issues that suppress bid density.
TARGETING INSPECTION
Reviews all cust_params key-values including IAS brand safety, Permutive audience segments, viewability signals, and privacy flags.
PRIVACY & CONSENT CHECKS
Checks GDPR consent string presence, GPP privacy strings, NPA (non-personalized ads) flag, PPID presence, and TFCD child-directed content flag.
INSTANT HEALTH SCORE
Every request gets a 0-100 score with Critical / Warning / Healthy status. Prioritized action plan tells you exactly what to fix first.
Built For
You've been on a call with Google support for two hours.
Your video render rate dropped 30% overnight. The ad unit looks fine in GAM. Prebid is returning bids. But the ads just won't serve.
Nine times out of ten, it's a duplicate key. Or a description_url=n. Or a missing env param. Things that GAM won't tell you — but this tool catches in seconds.
Built for AdOps Directors, Revenue Ops Managers, Yield Analysts, and Publisher Engineers who need answers fast.
