Product reviews and ratings. Product reviews is one of the best forms of the marketing. Asking for feedback on products gives customers a voice, at the same time lettings potential customers know what other people think about your products. nopCommerce also supports the review helpfulness feature (“Was this review helpful to you?”) 

Sitemap. There are two popular versions of sitemaps, and nopCommerce supports both of them. An XML sitemap is a structured format of a site that a visitor doesn't need to see. The sitemap gives information about the pages on a site to search engines: their relative importance to each other, and how often they are updated. HTML sitemaps are designed for users, to help them find content on a page. They don't need to include each subpage. HTML sitemaps help both visitors and search engine bots find pages on the site.
