eCommerce SEO - Ranking Category Pages

I have a site with hundreds of product pages in a particular Niche for about six years and they're all working well what do you think would happen if I add hundreds of products of a completely different Niche on the same domain so it's a it's an e-commerce site with multiple products already but you're adding a load of new products that aren't the same niche in general with products you're not actually going to be ranking the products

themselves with e-commerce SEO 9% of the time because people aren't searching the product name they're searching for brand names or they're searching for generic terms like you know like Buy cars online or buy hats online on things like that it's more about ranking the category Pages than the product pages themselves if you go and add 500 a thousand new products onto the site which are completely different from the current website that means that you have all

these new categories and things that you're going to need to rank that essentially means that you're going to have to add new levels of topical Authority new links new trust signals all sorts of things for these categories to actually allow you to rank them in the first place
