What kind of domain name shall I choose?

Hi there, I wanted to start a new Amazon affiliate website. Need some suggestions from experts. What kind of domain name shall I go for ? Why ? And how does it matter in terms of SEO? Niche Based Brand Name E-Commerce Reviews I’m just curious about a few things, so just wanted to clear my mind. As I’ve selected 3-4 micro niches which I want to target. And everyone knows that reviews are the best thing to intercept user to buy directly from Amazon. Haven’t given any thoughts about brand name or E-Commerce.
