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.
