The information in this thread is aimed to be the ultimate list of every single keyword research tool, method, technique, app, website, etc., in existence. What keyword research tools and methods do you use? Whatever it is, please list it here. It doesn't have to be just software. It could be an app, or a website that has useful tools on it, google research tools, or EVEN things/techniques/methods you do or tools you use for research that are not necessarily meant for keyword research, AKA (thinking out of the box, son!) ANYTHING goes. List EM' here!
