When you have a unique KW who has very small or zero search results you become a "Category King" ! And you can dominate google within a few months when users typing that KW in google for brand search (use it on your social media profiles too!) .
It's not easy to find such unique KW even with the namelix tool or with gemini/copilot AI , the AI's spill out words and phrases trhat are taken as com domains and as trademarks, not usefull. These AI tools are best for content creation, not for category design, the AI knows the science methods big marketing agencies using, to creating brand names, but itself is not capable doing this.
Category design example: 5hourenergy, for you to imagine this method.......or the RPM method of Tony Robbins as example.
