My name is Alex, I'm a guru here at Shopify!
No problem! Shopify auto-generates canonical tags for you - there's more detail on that in our guide right over here! That guide is a great starting point for SEO information, and we've also got a couple video guides that can help with next steps - Ecommerce SEO 101 and A Beginner's Guide to Content Marketing are both awesome resources. If you'd like to dive into SEO a little deeper, our blogs have a wealth of information as well!
Hope that's helped! Please feel free to give us a call or start a live chat at any time, we're open 24/7 for your convenience and always happy to assist!

Thanks for the hint. I only found: 'Some SEO is taken care of automatically: auto-generated canonical tags are added to pages to prevent duplicate content from appearing in search results'
Does it mean for all pages Shopify will auto create the canonical tags? Does it mean for product pages only? The 'Improving SEO' section doesn't tell much. Thanks.
