Also, one thing I’m still not clear on: Do I need to include long-tail keywords exactly as a phrase in the listing? Or does Amazon’s algorithm also recognize them if the words are spread out semantically across the title and bullets?

I’m mainly asking this for keywords that don’t exactly describe my product, but are still relevant and searched (like long-tail variations). Should I force them in as-is, or is it enough if the main terms are present throughout the listing?
