If your goal is testing various combinations of headlines and descriptions so you can optimize your results accordingly,which two responsive search ads benefits will help you dothis?

Responsive Search Ads (RSAs) allow you to provide multiple headlines and descriptions, which Google then automatically tests in various combinations to determine the best-performing ones. This process directly leads to greater flexibility in ad creation and testing, as you're not limited to a single static ad copy. By testing these combinations, RSAs aim to show the most appropriate ad to each user, leading to more relevance for the search query. This relevance, in turn, can improve ad performance metrics. Low eCTR (expected click-through rate) is a metric, not a benefit that helps with testing. Longer funnels and less click fraud are not direct benefits of RSAs for testing ad copy combinations.
