The honest take
Google Tag Assistant is invaluable when you're debugging a specific page in the moment — you've just pushed a new GTM tag and you want to see if it fired correctly. It's the right tool for real-time, in-browser tag inspection. It's free, it's made by Google, and every analytics professional should have it installed.
Check My Tracking is for the moment after. Once the tag is live, you want to audit the entire GA4 property — not just what fired on a single page, but whether conversions are configured correctly, whether Consent Mode v2 signals are set in the right order across your CMP, whether your GTM container has paused tags quietly failing, whether the data quality has drifted. That's a different job, and Tag Assistant can't do it.
The other key difference is workflow. Tag Assistant produces no shareable artifacts — it lives in your browser session and disappears when you close the tab. Check My Tracking generates structured reports you can share with clients via read-only links, export as white-labeled PDFs, and track over time. If you work with clients or teams, that audit trail is essential.
Common questions
Should I use Tag Assistant or Check My Tracking?
Use both. Tag Assistant is the right tool for debugging a specific page in real time — checking if a tag fired, what data it sent, what the datalayer looks like. Check My Tracking is for auditing the full GA4 property configuration, consent implementation, event tracking health, and data quality across your entire setup. They don't replace each other.
Does Check My Tracking replace Tag Assistant for consent debugging?
Not entirely. Tag Assistant lets you watch consent signals fire in real time as you interact with a CMP. Check My Tracking runs 12 automated Consent Mode v2 checks including pre-consent cookie blocking (via Playwright browser inspection), signal initialization order, and update propagation — but it's a batch audit, not a live debugger. For complex CMP debugging, you may want both.
Is Check My Tracking worth paying for if I already have Tag Assistant?
If you manage GA4 for clients or multiple properties, yes — significantly. The value isn't in replacing Tag Assistant's real-time debugging; it's in the audit depth (65+ checks, GA4 Admin API config validation, GTM container inspection), the reporting artifacts (shareable links, PDF export), and the historical tracking that shows you when things changed.
