This is seen as Google’s way of pushing automation through their ad products.
Beginning in July 2022, advertisers will no longer be able to create new ETAs or edit existing ETAs in Google Ads according to an announcement by Sylvanus Bent, Product Manager, Google Ads .
“Your existing expanded text ads will continue to serve alongside responsive search ads, and you’ll still see reports on their performance going forward. Additionally, you’ll be able to pause and resume your expanded text ads or remove them if needed. You’ll also still be able to create and edit call ads and Dynamic Search Ads” said Bent.
