We are redesigning our website on prestashop. Template has already been purchased. Need to make additional changes to it. List of changes is below; 1. Show price range of reg-plus on category pages 2. Add Instagram Share button to Product Pages 3. Add Infinite Scrolling and Canonical URL's to remove duplicate content for supplemental category and product pages. (add "rel=canonical" tag to page source) Option available in prestashop admin via "Preferences -> SEO & URL -> Redirect to the canonical URL" - S.K: The theme is defect in a way that it doesn't create arelevant <link rel="canonical"/> in the header file - I will correct it 4. Add Google SERP snippet mark-up so "Product Features" show up in google search results for "what is" queries ([login to view URL], structured data) 5. Change code so theme has max 4 image sizes across all screen sizes. And ensure all images are resided in those 4 sizes. 6.
