Performance Max Ad Strength

Ad Strength in Performance Max incorporates new signals that can help you achieve optimal performance across various inventory types. While creating and optimizing your Performance Max campaign, Ad Strength is a good indicator for you to understand if your asset group has breadth and depth to maximize campaign performance.

Note:
  • You may notice a decrease in Ad Strength scores as Google surfaces new ways to guide you towards optimizing your asset mix.
  • While we’ve found a correlation between increasing Ad Strength and performance, these updates won’t cause a change in your campaign results.

Ad Strength Principles

  • Incomplete: This asset group lacks minimum assets to serve.
  • Poor: This asset group only serves to some available inventories because it only has the minimum assets required to launch Performance Max (in other words, not enough breadth).
  • Average: The asset group has all asset types to serve all available inventories, however it lacks variety for better performance (in other words, not enough depth).
  • Good: This asset group has all asset types, good asset varieties, and good text diversification (in other words, good breadth and depth).
  • Excellent: This asset group has all asset types including optional ones that won’t impact inventory but are good for performance (sitelinks, landscape logo, square image), excellent text diversification, and excellent asset varieties (in other words, excellent breadth and depth).
