Google looks to be doing a push to encourage users to search for deals with a new banner in the middle of organic search results. Clicking the banner takes you to a “shop deals” query which again features the same banner styling with custom results, where you’re then able to navigate deal categories. The mobile version looks different.
This test ended up being an official announcement from Google in November. The launch was a set of features to allow users to finding holiday shopping deals on Google, including saving products, tracking prices, and getting price insights in Chrome and Search.
