What's the main difference between Performance Max and Standard Shopping ads in terms of how they reach consumers?

The fundamental difference between these two campaign types lies in their scope and automation; Performance Max uses AI technology to reach a wider audience across all of Google's inventory, including YouTube, Display, Search, Discover, and Gmail, whereas Standard Shopping ads have a more targeted reach primarily focused on the Shopping tab and Search results. While Standard Shopping offers more manual control over specific networks and bidding, Performance Max leverages machine learning to find conversion opportunities across the entire Google ecosystem that a merchant might otherwise miss. This distinction makes Performance Max a comprehensive "all-in-one" solution for maximizing visibility, while Standard Shopping remains a specialized tool for retailers who prefer granular, manual optimization of their product placements.
