I'm talking about this region, which is usually populated by a few icons from famous sources, and they don't even have labels:
You.com shows that people want from information from these smaller domain-specific indexes and IMO Brave's way is the best model right now (balance of performance, amount of content on screen and number of sources):
https://search.brave.com/search?q=singin+in+the+rain&source=web
https://search.brave.com/search?q=origin+of+species
https://search.brave.com/search?q=di+caprio
https://search.brave.com/search?q=yellow+submarine
To be completely honest, the "people also searched for" Kagi puts on the same place is much less relevant than a good amount of good sources on the specific search query because it's basically making the user find what they are looking for through multiple searches in adjacent topics (ad-based search engine tactics) instead of giving what was asked.
