Here are my five dimensions: the number of products, categories, followers, ratings, and reviews. Meantime, for eCommerce software such as Shopify, I added the Alexa rank and social data.
According to these, I designed an all-in-one store spy tool – SellerCenter, covering Shopify, AliExpress, Amazon, Wish, Shopee, Lazada.
I hope this tool is useful. And I am trying to improve it......
