Tag Manager Updates & Release Notes

Google tag gateway for advertisers integrations with Akamai and Fastly are now available

This release introduces a streamlined integration to configure Google tag gateway for advertisers using Akamai or Fastly as your content delivery network (CDN). You can now authorize Google to automatically detect your CDN zones and inject routing rules directly from the Google tag interface, eliminating the need for manual configuration in the Akamai Control Center or Fastly dashboard. By automating the deployment of first-party measurement paths and geolocation headers, these integrations give you greater control over your data, improve the accuracy of your Google Analytics reporting, and drive conversion uplift through enhanced signal recovery.

Google tag gateway for advertisers via Google Cloud Platform is now in available in Beta

This release introduces a new workflow for Google tag gateway for advertisers, allowing you to leverage Google Cloud Platform’s Global external Application Load Balancer. This "one-click" integration directly in GTM and Google tag settings, streamlines deployment and configures your Google tag and tag containers to send data through your first-party web infrastructure before it is relayed to Google, helping to improve data signal quality.

readAnalyticsStorage sandbox API

The readAnalyticsStorage sandbox API is now available. This client-side JavaScript API allows developers to read client and session IDs in a custom template. Previously, developers relied on reverse-engineering or custom parsers to understand Google-set cookie formats, which wasn't a reliable approach. It was prone to breaking whenever Google Analytics updated its cookie formats.

Now, the readAnalyticsStorage API allows Tag Manager users to safely read the necessary cookie parts, future-proofing their approach and preventing interruptions from format updates. Learn more about Custom template APIs.

Conversion parameters for Floodlight Sales tags

• Merchant ID: The Google Merchant Center ID of the retailer.
• Merchant Feed Label: A label identifying the specific feed used within Google Merchant Center.
• Merchant Feed Language: The language of the feed, represented using the 2-letter ISO 639-1 code.

These parameters will be passed within the Floodlight tag's URL as mid, fcntr, and flng respectively. The data sent through these parameters can be used to distinguish the item_id from other product feeds and merchants. This approach mirrors the implementation currently used by Google Ads conversion tracking and offline Floodlight conversions. Learn more about setting up conversions with cart data.

Tag Diagnostics updates

We’ve added new diagnostic alerts and a recommendation to the Tag Diagnostics tool in the Google Tag settings:

• Your tag data may be restricted: This recommendation appears when we’ve detected that you are using a Content Delivery Network, like Cloudflare, that Google supports but the first-party mode is not enabled. To fix this you can enable first-party mode or you can dismiss the recommendation.
• Missing gtag config command: This diagnostic appears when we’ve detected that your Google tag code isn’t configured correctly, which may prevent your property from measuring automatic events. To fix this issue, place your Google tag configuration code immediately after the opening HTML tag on all pages of your website. Learn more about setting up the Google tag on your website.
• Missing Google tags: This diagnostic appears when your event tags in Google Tag Manager don’t have matching Google tags. To fix this issue, add a Google tag for each of your measurement products, including Google Ads, Google Analytics, and Floodlight.

You can now dismiss tag diagnostics alerts that show in the Tag Diagnostic tool, but not all alerts or recommendations can be dismissed. Dismissed alerts can resurface if certain conditions are met. Dismissing alerts won’t affect your overall tag quality and will be moved below the active action items. Learn more about troubleshooting tag issues with Tag Diagnostics.
