Q:

Pathfinder encounter building checklist

I have been GMing in pathfinder for a little under a year now and I have recently realized that I have not been taking full advantage of certain aspects of combat encounters such as terrain effects and such.
I looked online for a checklist of possible things such as, difficult terrain, special objects and hazard that you can add to an encounter but all I found was hero lab and encounter generators which is not what I want.
Is there a manual checklist that I can use to make sure I have at least thought of each mechanical part of an encounter, such as rough terrain or hazards?
It should be easy to copy so I can use it for multiple encounters.

What encounter features make low CR enemies challenging?
How do I design exciting, fun boss fights for my players?
How do I build interesting dungeons?
Tips for making encounters more interesting

But possibly the most comprehensive aid on this topic I've found is this;
