Test a DCM Tag →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

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.

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