Search Campaigns vs Performance Max: What's the Difference?

A Search campaign is the traditional Google Ads structure - you choose the keywords that trigger your ads, set match types to control how loosely they're interpreted, and can manage or steer bidding directly. It runs exclusively on Google Search results and the Search Partner network, and it gives you a clear, keyword-level view of what triggered each click.

Performance Max (PMax) is a single automated campaign type that runs across all of Google's inventory at once - Search, Display, YouTube, Discover, Gmail, Maps, and Shopping - built from asset groups (headlines, images, descriptions, video) that Google's machine learning combines and places based on your conversion data and audience signals. There's no keyword list to manage, and far less visibility into exactly where and to whom each ad showed.

The real tradeoff is control versus reach. Search campaigns let you see and adjust which query triggered which click; PMax trades that visibility for broader reach and automated placement decisions, which can surface real incremental volume but also makes it harder to catch low-quality inventory the algorithm decides to chase. The common approach for lead-generation accounts is to run both together - Search for high-intent, measurable terms, PMax layered on top for incremental reach - while watching PMax's available reporting closely rather than assuming the automation is always finding good traffic.
