Frequently Asked Questions

Find Quick Answers

What Google tags does this tool check for?

The tool checks for Google Analytics (both GA4 and Universal Analytics), Google Tag Manager, Google Ads conversion tags, Google Optimize, and other common Google marketing and tracking tags.

Can I check tags without visiting the website?

Yes! You can either enter a URL (the tool will fetch the HTML) or upload an HTML file directly from your computer for offline analysis.

Does this tool modify or add tags to websites?

No, this is a read-only verification tool. It only analyzes existing tags and never modifies or adds tags to any website.

Why are some tags showing as 'Not Found' or 'Invalid'?

Tags may show as 'Not Found' if they're not installed on the page. 'Invalid' status indicates the tag exists but has configuration issues (like missing tracking ID or syntax errors).
