Etsy’s sections are a great way to guide customers to the products they might be interested in. Shopify does not have sections - the closest thing Shopify has to sections are collections.
With Etsify you can migrate your Etsy Sections as Shopify Collections, this means that Etsify will create your Etsy Sections as Collections in Shopify and associate the relevant products to these Collections.
Another option that you have is to migrate the sections as additional tags, this will help your customers laser focus on their interest and find the right product while they browse through your Shop. But, you probably enough tags in your Etsy listings, that the Section won’t have an added value.
If you have a lot of Tags in your Etsy products (I bet you have at least 13! :)), see here a short tutorial on how Etsify helps you migrate only the right tags to Shopify.
