Ad Strength in Performance Max incorporates new signals that can help you achieve optimal performance across various inventory types. While creating and optimising your Performance Max campaign, ad strength is a good indicator for you to understand if your asset group has breadth and depth to maximise campaign performance.
Note:
- You may notice a decrease in ad strength scores as Google surfaces new ways to guide you towards optimising 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, horizontal logo, square image), excellent text diversification and excellent asset varieties (in other words, excellent breadth and depth).
Great creative drives results: Google found that advertisers who improve their Performance Max ad strength to 'Excellent' notice, on average, 6% more conversions. Learn more about Gemini models that are coming to Performance Max.
