Google Ads doesn't publicly share the exact formula used to calculate the asset performance rating in Performance Max campaigns. However, we do know some key factors that contribute to it:
Conversion data: This is the primary factor influencing asset performance ratings. Google Ads analyzes how each asset contributes to conversions (e.g., clicks, leads, sales). Assets that lead to more conversions and higher conversion value will receive a higher rating.
Engagement metrics: Google also considers how users interact with your assets, including click-through rate (CTR), impressions, and engagement rate. Assets that generate more engagement are likely to be rated higher.
Relevance and quality: Google evaluates the relevance and quality of your assets based on factors like keyword alignment, image quality, and text clarity. Assets that are deemed more relevant and higher quality are likely to receive a higher rating.
Learning phase: When you first launch a Performance Max campaign, the asset performance ratings will be marked as "N/A" until Google gathers enough data to make accurate assessments. This typically takes a few weeks or even months, depending on the campaign and traffic volume.
