Shopify collections are the category pages of your store. They group products together so customers can browse by type, and they're often the highest-traffic pages on a store because they rank well for broad category search terms. Getting the collection structure right is one of the most impactful things you can do when setting up or reorganising a Shopify store.
Manual vs smart collections
Shopify has two types of collections:
Manual collections contain products you add by hand. You select exactly which products are in the collection and control the order. Right for curated collections with a specific selection that doesn't follow a pattern - "Staff picks", "Gift ideas under £50", "New arrivals" (though new arrivals is better as a smart collection).
Smart collections add products automatically based on rules you define. A rule like "Product type is equal to Dresses" automatically adds every product tagged as a dress. Rules can combine: "Product type is Jackets AND Vendor is Acne Studios". Smart collections are self-maintaining - add a new product with the right tags, it appears in the collection automatically.
For most stores, smart collections are the right default. They eliminate manual maintenance as your catalogue grows and ensure products never get missed from relevant collections because someone forgot to add them.
The collection structure most stores need
A well-structured Shopify catalogue typically has collections at two levels: main categories (the top level in your navigation) and sub-categories (accessible within main categories or via filters).
Main categories are broad groupings that customers would expect to see in navigation: Women, Men, Home & Living, Skincare, Electronics - whatever makes sense for your product range. Keep top-level navigation to 5–7 items maximum.
Sub-categories are more specific: Coats & Jackets, Knitwear, Dresses within Women. These can live as collections in your navigation dropdown, or as filter options within a broader collection.
Additionally, most stores benefit from a few functional collections that cut across categories:
- New arrivals - smart collection, rule: created in the last 30–60 days
- Sale / Outlet - smart collection, rule: compare at price is greater than 0 (meaning it has a strikethrough price)
- Best sellers - manual collection, updated periodically with your top-performing products
Collection SEO: what to add to every collection
Collection pages rank for category-level search terms - "women's linen trousers", "oak dining tables", "natural skincare UK". For this to happen, the collection needs actual content, not just a product grid.
For every main collection, add:
A collection description. 80–200 words describing what's in the collection and who it's for. Written naturally, mentioning the types of products available and the occasions or needs they serve. This text is indexed by Google and contributes to the page's relevance for category searches.
An SEO title and meta description. In the collection editor, scroll down to "Search engine listing" and customise these. The default is often just your collection name plus your store name - usually not what someone would search for. Rewrite the title to include the keyword a customer would use.
A clean, keyword-relevant URL. Shopify auto-generates collection URLs from the collection name. "Collections/womens-linen-trousers" is better for SEO than "collections/wlt-2024". Check the URL when creating each collection and adjust if the auto-generated version is unclear.
Navigation: how to surface your collections
Collections you build but don't surface in navigation are invisible to customers who aren't explicitly searching for them. Your Shopify navigation (Customise → Navigation in the theme editor) should expose your collection hierarchy clearly.
A standard navigation structure:
- Main menu: links to top-level collections
- Dropdown menus: sub-collections within each top-level category
- Footer: links to functional collections (new arrivals, sale, bestsellers)
Keep your main navigation to items most customers will use. A navigation with 12 top-level items overwhelms rather than guides. If you have many categories, group them in dropdowns rather than listing them all at the top level.
Filtering and sorting
For stores with more than 50 products per collection, filtering significantly improves the browsing experience. Shopify's native filtering (called "Search & Discovery") lets customers filter by product type, vendor, price, colour, size, and any other product attribute you've set up.
Enable filtering in Shopify admin → Apps → Search & Discovery (installed free from Shopify). Configure the filters that are relevant to your product category: size and colour for fashion, material and dimensions for furniture, flavour and format for food.
Sorting options (best selling, newest, price low to high) should be available on every collection page. The default sort order for most collections should be "best selling" - customers expect to see what's popular first, and your top-performing products convert better when they're more visible.
The mistakes worth avoiding
Too many collections with very few products. A collection with two products looks sparse and undermines confidence. Either consolidate small collections into a broader one, or wait until you have enough products to justify the collection before creating it.
Collections with no description or SEO content. Shopify creates the collection page automatically when you add a collection. The default is empty - just a product grid. Without a description, the page is competing for rankings with no text content. Add a description to every main collection before you drive traffic to it.
Manual collections that don't stay updated. If you use manual collections and add new products but forget to add them to collections, products disappear from your catalogue. Either switch to smart collections for anything where automatic maintenance matters, or create a process for updating manual collections when new products are added.
