Both.
start off single niche: wireless computer trackballs
then cover that topic in depth, become the expert, then step up:
Computer trackballs
Computer mouse, trackballs, trackpads
Computer peripherals(monitors, printers, cables)
Laptops
Desktops
Servers
Office chairs
Gaming chairs
Desks
Standing desks
then when you cover a niche from head to toe, nothing more can be put into it, add a new niche:
Home decoration
Home office decoration
Smart home accessories
And just keep building!
as you build up on a micro niche, you gain authority, then slowly expanding it, you gain more authority and leverage the authority you have. This keep compounding.
unless you can upload 100’s of quality articles tomorrow to cover multiple niches then build from there, this should be your plan.
