What is the difference between Expanded Text Ads and Responsive Search Ads?

• A. RSA tests multiple headlines and descriptions; ETA had fixed headlines and descriptions.
• B. RSA had fixed headlines and descriptions; ETA tests multiple headlines.
• C. ETA and RSA are identical.
• D. RSA uses only the first headline.

Answer: (C)

The key idea here is how each ad format handles copy testing and presentation. Expanded Text Ads use a fixed set of headlines and descriptions that you write and that appear exactly as written. You provide the copy once, and Google serves that static version. Responsive Search Ads, by contrast, let you supply a larger pool of headlines and descriptions. Google then tests different combinations of these assets and serves the combinations that perform best for the user’s query, device, and context. This means RSA automates optimization across multiple variations, while ETA is fixed and manual. So the best summary is: RSA tests multiple headlines and descriptions and serves optimized combinations, whereas ETA uses fixed headlines and descriptions.
