I am just building my first amazon website. At first I ordered some kw's from the marketplace and the terms where very niche targeted - I'm not a stranger to kw research so done a bit of digging around myself and found some other kw's that were low comp which were slightly relevant to the original keywords I brought. My question is should I be focusing on a very small niche or should I open up a little to introduce other types of products/target audiences? For example if my keyword was 'best camping shoes' should I focus my website just on camping shoes and other specific camping products? Or should I have a website that has sections such as Camping, Traveling, Hunting etc and then target keywords such as best traveling suitcase and best hunting knife. I read that having an authority website would be better... but I didn't want to go over board.
