Several announcements at GML addressed the same underlying problem: the signals going into Google’s automated systems are often incomplete, misaligned with business goals, or technically leaky. Three tools are Google’s answer to that.
Google Tag Gateway (GTG).
Routes conversion tag signals through your own domain’s server rather than Google’s infrastructure. The result is better data accuracy, higher match rates and first-party data more resilient to browser-level tracking restrictions – with no changes to existing tag code. GTG provides 11% more signals through Confidential Matching for advertisers using customer match – a direct performance unlock.
Product Value Adjustments (PVAs).
Allows ecommerce advertisers to apply conversion value multipliers to specific SKUs directly within Merchant Center or Google Ads – without touching campaign structure. Brainlabs outline the practical applications: upweighting high-repeat-purchase products, deprioritising high-return SKUs, or accelerating sales of overstocked inventory.
Data Manager API Updates.
Google’s centralised hub for connecting first-party data now has direct connectors to Mailchimp, ActiveCampaign and Klaviyo. This is a real improvement for mid-market advertisers, where getting CRM data flowing reliably into Google’s systems has been a persistent barrier.
