Results may vary:

Searches for Amazon, Temu, Shein - result in each being listed in the promotional panel and then as the first result.

For Firefox: Chrome is listed in the promotional panel and Firefox as the first result (below it).

The promotional panel has a different background colour and “Ad” badge, but is otherwise identical to other listings.

Two results fit on the screen: the promotional panel and the first listing. Diverging from Google is that the ad result is obvious and doesn’t push the search result out of view.
