Check a Tag →What gets checked
Vendor auto-detection
30+ ad-server and verification profiles. Identified by tag structure, URL patterns, and macro signatures.
Macro compliance
Every tag checked against its vendor's macro requirements. Missing macros auto-inserted using verified GAM syntax.
SSL audit
Every network request traced for HTTPS compliance so you don't ship mixed-content that breaks in secure contexts.
Landing page test
Click URL followed through the redirect chain, HTTPS verified, load time measured, loops detected.
TCF / GDPR consent
Consent macros detected, CMP API presence checked, TCF 2.0/2.2 strings validated.
Bulk upload
Excel or CSV with up to 25 tags per batch, with auto-column-mapping for trafficking sheets and vendor exports.
How it works
Paste any ad tag
Single tag or paste many — we handle INS tags, JS tags, IMG redirects, VAST URLs, VAST XML, iframe tags, pixel URLs.
Vendor detected, macros inserted
We identify the vendor and insert the correct macros for trafficking — so the test matches real GAM behavior.
Full compliance report
Risk score, IAB compliance, SafeFrame analysis, pixel classification, landing-page test, SSL audit, and every finding prioritized.
