Here is justification for removing ‘pages’ from Shopify URL. Let us compare two below URLs. Even if we work hard on SEO work, the first url is not going to show up in searches but the second one might. When we search a product, Amazon shows up at the top. If some good SEO work is done by Shopify then Shopify search results may show up close to those of Amazon. But for some hidden reason, Shopify does not seem interested in that. If Shopify can work on general SEO / Page Speed etc, then the search results will increase drastically. The second url generation is possible in Woo-commerce, but not in Shopify.
