As I wrote elsewhere in the comments we're planning to redesign the results page and rewrite all the text later this year. The current page hasn't changed much since mid-2016. Need to refresh/expand technical advice, be more clear about the limitations of the service, etc. I'll note down all suggestions here.
I'd also like recommend a similar project that was inspired by Webbkoll: https://privacyscore.org/ -- it's slower, but also integrates things like testssl.sh, and most importantly lets you make lists of URLs to check. It uses OpenWPM [0] which has been used for many interesting studies,[1] such as "Online Tracking: A 1-million-site Measurement and Analysis".[2] (Webbkoll uses Phoenix+Puppeteer)
