What are Responsive Search Ads? RSA’s cater to consumer demand for more personalized marketing messages. Today, no one ad is right for everyone all of the time. So RSAs enable machine learning to drive highly personalized ads designed to resonate with search users. RSAs allow you to create an advert with a range of headlines (up to 15) and descriptions (up to 4) that are automatically tested in different combinations to find the optimal ad to show for each specific search term. Keep in mind that responsive search ads are limited to 30 characters per headline. Use punctuation creatively by incorporating dashes and colons to make the most out of the limited space. This allows your ads to compete in more auctions, while delivering the most relevant message for a variety of different queries. RSAs display three of your headlines and two of your descriptions at a time, plus a customizable URL based on your landing page path. 2 Marin Software
