I'd like to promote sites in my search results, preferably using a query rule as described in this post https://blogs.technet.microsoft.com/tothesharepoint/2013/10/03/how-to-change-the-order-in-which-search-results-are-displayed-in-sharepoint-server-2013/
I figured that a Manual Condition would do as described in this image (I would Promote to top instead)
However, I can't find what to use to instead of ContentType since sites aren't a contenttype. I'm thinking of something like ResultType:Site
Any advice?
Thanks
