Google AI Mode now showing descriptions for ads

Google AI Mode is now showing descriptions for ads appearing at the bottom of the page. I spotted this while searching something in the Ai mode, and it looks like a new test, since Google was previously just showing ads with sitelinks in AI Mode, without any description below them. This felt new to me.

Here is a screenshot of how it looks.

Showing a description alongside the ad is a good addition for the websites ranking there, since it also gives users something to read about the site before clicking on it.
