What gets checked

Tag format detection

INS (data-dcm-ad-tag-value), JavaScript tags, IMG redirects, and legacy iframe formats all auto-detected.

Click macro analysis

Detects %%CLICK_URL_UNESC%%, %%CLICK_URL_ESC%%, data-dcm-click-tracker. Auto-inserts missing click macros.

Cache busting

Validates ord=, %%CACHEBUSTER%%, and vendor-specific cachebuster parameters are present and correctly placed.

SSL compliance

Every network request is checked for HTTPS. Mixed-content flagged so your tag doesn't break in secure contexts.

Landing page validation

Click URL is followed through the redirect chain to verify landing page responds, uses HTTPS, and loads reasonably fast.

Network behavior

Every domain called by the creative is classified (ad server, measurement, tracker) so you know what the tag is really doing.

How it works

Paste your DCM tag

Supports INS tags, JavaScript tags, IMG redirects, iframe tags — just paste and go.

Tag executes in a sandbox

We render the tag in a headless browser with synthetic GAM macros, capture every network request, console message, and cookie access.

Detailed compliance report

Risk score, IAB compliance, macro analysis, SSL audit, landing page check, and vendor classification — everything you need before trafficking.
