SGE pulls information from Google Business Profiles, Google Merchant Center, and the internet. Some information that SGE presents was previously highlighted in a SERP feature. For now, the SERP feature still appears in search results beneath the SGE box.
Here’s another example. The following two images are for the same search. The SGE result was provided first and then the local pack. All three restaurants in the local pack appear in the SGE result but in a different order. SGE also included additional restaurants.
