As I'm having quite many article under one of my categories (Investments), I'm thinking about creating new subcategories (e.g. Real Estate Investments) under my main category and move some posts there.
Would moving some of my existing posts in the Investments category to a newly created subcategory (e.g. Real Estate Investments) impact my site negatively from an SEO point of view?
Please note: My URL structure does not contain category name, so that's not an issue. I'm thinking more about cannibalisation, duplicate content etc.
