Tag inventory
Tag X-ray
Browser session capture
The tool opens the page in a headless Chromium session and records the cookies, requests, tags, and dataLayer activity visible during that run.
Scoped rule set
Each tool applies a narrow ruleset to the captured session. It is useful for implementation QA, not a full-site crawl or legal determination.
Point-in-time report
Results show what was observed in that session, with severity labels and evidence. Re-run after changes or if your site varies by region or user state.
What we check
Tag inventory (40+ brands)
Identifies every tracking tag on the page. GA4, GTM, Meta, TikTok, LinkedIn, Hotjar, and dozens more.
Firing timeline (ms-accurate)
Records exactly when each tag fires, down to the millisecond, relative to page load.
Consent compliance per tag
Flags tags that fire before consent is given, violating GDPR and ePrivacy regulations.
Tag count & performance
Measures total tag count and flags when excessive tags are degrading page performance.
How to read results
Tags are sorted by first-fire time. Pre-consent tags appear at the top and are flagged.
Common issues we find
Tags firing before consent banner loads
Marketing pixels like Meta or TikTok fire in the first 100ms, before the CMP even initializes. Fix: load all non-essential tags via GTM consent triggers.
Multiple tag managers conflicting
Both GTM and a hardcoded gtag.js on the same page, causing duplicate events and inflated data. Fix: consolidate all tags through a single GTM container.
20+ marketing tags hurting Core Web Vitals
Excessive third-party tags add hundreds of milliseconds to page load. Fix: audit which tags deliver ROI and remove the rest.
