How to best structure product collections for SEO?

Hi all,

My shop sells engraved signage, mainly slate signs. I have around 70 products on my store.

I am wondering how to structure my products on the site. And if it’s better to have one collection, with product types filtered with tags. Or to have multiple smaller collections without the product tags - is there any benefit either way, maybe for SEO?

For example:
One Collection Called ‘Slate Signs’
Then different tags for each set of products such as Slate Signs On Posts, Square Slate Sign, Rectangle Slate Sign, Round Slate Sign, etc.

Or multiple collections for each - Slate Signs On Posts Collection, Square Slate Sign Collection, Rectangle Slate Sign Collection, Round Slate Sign Collection, etc.

Any thoughts/advice is greatly appreciated. Many thanks in advance.

@KrisG2 - you have 70 products, so I recommend multiple collections

Do you know if
my current site map is structured as:

http://domainame/category/products/item-landingpage.html

But I change the web folder location of the item-landingpage.html to:

http://domainame/category/products/sub-cateogry/item-landingpage.html

Will this new folder structure reindex my page and look at this existing item as an update or as a new page to a website?

I’m trying to minimize of having items falling off the top of google search rankings on my items.
