Starting October 15, 2024, Google will automatically activate Travel feeds for advertisers who connect their Hotel Center feed to Google Ads.
This update will enhance search ads with real-time hotel prices, images, and relevant details, aiming to boost user engagement and ad performance.
The new feature is expected to increase click-through rates by up to 20% and offers easier management at both account and campaign levels. It will apply to both specific hotel searches and broader queries, such as “hotels in Boston” with advertisers automatically opted in upon connecting their feed.

This update was spotted by Adriaan Dekker and Rudolph Dekker.
Here is the official announcement: Improve ad performance with Travel Feeds in Search Ads.
