Adriaan Dekker shared a new update on how Google has added new warnings and recommendations to the Tag Diagnostics tool to help advertisers catch and fix tagging issues more effectively.
What’s new:
- Your tag data may be restricted
Appears when using a supported CDN (e.g., Cloudflare) without first-party mode.
Fix: Enable first-party mode or dismiss if not needed. - Missing gtag config command
Shows up when the config code is missing or incorrectly placed.
Fix: Add it right after the opening<head>tag on all pages. - Missing Google tags
Triggered when GTM event tags don’t have matching Google tags.
Fix: Add a Google tag for each product, like GA4, Ads, or Floodlight.
Google has launched Tag Diagnostics in March 2024 and has been continuously adding new features to support advertisers.
