Household Income Exclusions for Performance Max Campaigns

The update is particularly valuable for brands selling high-ticket items or those with clear income-based purchasing patterns.

Target-Based Bidding Update for Ecommerce

A subtle but important change came in the form of a target-based bidding update for ecommerce advertisers.

This new model allows advertisers to set specific targets—such as cost per acquisition (CPA) or return on ad spend (ROAS)—and Google's algorithms automatically adjust bids to meet those targets. The change is designed to give advertisers more control while leveraging machine learning. Search Engine Journal provided an in-depth analysis, noting that the update is part of Google's ongoing effort to simplify campaign management for ecommerce Google Ads’ Target-Based Bidding Update For Ecommerce.

Advertisers can review these recommendations and apply them to improve measurement accuracy.
