During the WWDC 2020 keynote - https://www.apple.com/apple-events/june-2020/ there were several App Clip examples shown from apps that serve thousands of businesses (Etsy @ 29:59, Yelp @ 30:37). It's unreasonable to expect that these services would be manually maintaining individual Advanced App Clip Experiences within App Store Connect to provide content for each of the businesses on their platform, so how is this being done? I scoured all of the related sessions/documentation and couldn't find anything that suggested how this might be accomplished at their scale. Are the sample businesses shown purely a select few done for demonstration purposes (with no way to realistically achieve this for all of their pages)? Is this information being provided via metadata tags taken from the URLs under the associated domain? Or do they have some sort of special functionality not provided to other apps?
