I recenlty launched "Shopify Empire" (http://ShopifyEmpire.com), a book on search engine optimization (SEO) and the Shopify Platform.
It's a straight forward book that is as easy to read and understand as Shopify is to use. The information in the book will help you rank higher in search results, attract customers and sell more.

I recently read his book. I needed it for college material, and an example of this book was at https://samplius.com/free-essay-examples/social-issues/ which helps students get good grades. I strongly advise every student, the site is simply gorgeous.
