Website criteria (usability) checklist in 2017

I have been pondering a lot lately about my method. It's rare that we really sit down and try to map out what we know, although experience is a powerful point.
While it is part of one of my compensated choices, I've decided to reveal this checklist. A couple of disclaimers: First, I really don't claim this list is extensive or unique. Jakob Nielsen has a fantastic 113-point checklist for example, Homepage Usability, in his book. This really is my way of arranging what I feel is crucial while attempting to keep it manageable.

I try to keep it simple with 3 fundamental scores: (1) Green Check = Great/Move, (2) Red Check Always = Wants work, but no disaster, (3) Red X = Bad/Fail. Not allpoints are fundamentally applicable to all or any sites.

The "fold" is that imaginary line where the bottom of your display cuts off a a full page. Content can drop below the fold, but something crucial to comprehending who you are or that which you do (especially on the home-page) should fit on that first display.
