Collections, inventory, and tags: organizing your catalog before it grows

A well-organized catalog makes every other module easier

Collections are Shopify's way of grouping products so customers can browse by category, and so you can target specific groups in your homepage featured sections, your navigation menus, your email campaigns, and your ads. Getting the structure right now means you won't be reorganizing your catalog in three months.

This is the last setup lesson before module 5. By the end of it, your store has every product page filled in correctly, your products grouped into collections, your inventory tracking turned on, and a tag system that powers everything else you'll build later in the course.
