Kagi results come from different sources: Bing, its Teclis index, etc. A way to show where a result came from would be really helpful.
There are many ways to do this. Brave displays an estimated/inexact percentage of results that came from its own index when users click the "info" button below the search bar. Alternatively, the exact source could be included in the crystal ball infobox for some or all results.
Right now, it's sort of possible to figure out which results are original by doing a side-by-side comparison with a non-personalized Bing SERP (e.g. through DuckDuckGo) or by looking for commonalities between the main SERP and the "non-commercial" lens. Streamlining this would be appreciated, as it could help users see a greater value-add in using Kagi.
Perhaps a good start could be annotating the non-commercial results' crystal balls in the main SERP.
