Short answer
Responsive search ads (RSA) are Google search ads in which advertisers supply multiple headlines and descriptions. The system automatically tests combinations and shows those most likely to perform for each search. RSAs are the standard search ad format in Google Ads, and supplying varied, relevant assets helps the system find stronger combinations.
