Developer expert in shopify

THESE ARE THE POINTS THAT A DEVELOPER SUGGESTED TO ME I NEED: 1- My products don't have meta tags in the HTML. (For example, the brand should be enclosed with the correct metadata. This helps google to recognise the type of product you are selling. The full list of meta tags for the content type Product: [login to view URL]) 2- My pages structure is not very well designed. Google doesn't know where is the main content. (Look at the attached screenshot) This is from my home page: Untitled BODY Untitled NAV Your Cart 0 $0.00 SHOP Untitled SECTION CONTESSA VOLPI Links Join our Mailing List Payment Methods Social Networks Untitled NAV Join our Mailing List! 3- I would like to have have internal linking. (e.g. related product, customers who bought this also bought that, etc.). Google looks to sites with internal linking, favourably.
