Susana has recently implemented Responsive Search Ads (RSAs) on search campaigns. To best understand the full impact of her RSAs, how soon after implementation should Susana measure their performance?

The selected answer option is correct because Susana should measure the performance of her Responsive Search Ads (RSAs) 15 to 30 days after implementation to fully understand their impact. RSAs require a learning period to optimize, as they use machine learning to test various combinations of headlines and descriptions to determine which ones perform best for specific search queries. Within the first few days, performance may be fluctuating as the system gathers data, so waiting 15 to 30 days allows enough time for the ads to stabilize and provide more reliable performance insights. During this time, the system will have tested a variety of combinations and begun to optimize delivery for maximum effectiveness, allowing Susana to assess the full impact of the RSAs on her campaign’s success.
