I have an Amazon niche site with about 30+ product reviews that I wrote. The reviews within my current niche site are organized by category. I'm in the process of creating another website in the same niche, featuring most of the same products from my current site. The inner pages will feature the products by their brand affiliation rather than category. My goal is to target brand based long tail phrases within the same niche. The new site domain is a general key phrase within the same niche. Do any of you warriors see any issues with using the exact same reviews from the old site on the new site?
