The article discusses the introduction of Google's new ad strength metric, which evaluates the quality of advertisements on a scale from "poor" to "excellent." This feature aims to help advertisers optimize their ads for better performance by providing actionable insights based on various factors such as relevance and creativity. The new metric is expected to enhance user experience and improve ad effectiveness across the platform.

Instead, marketers should focus on a broader set of metrics, such as customer lifetime value, conversion rate, and engagement metrics, to gain a more comprehensive understanding of their campaigns' effectiveness.
