What is collection performance analysis?

Collection performance analysis measures how well each product grouping in your store performs across multiple dimensions. In Shopify, collections are a primary navigation and merchandising tool, acting as curated product pages that group items by category, theme, season, or use case.

The analysis goes beyond simple revenue ranking. A collection might attract strong traffic but convert poorly, suggesting the product assortment or page layout needs attention. Another collection might convert well but attract minimal traffic, indicating an opportunity to promote it more prominently in navigation and marketing.

Collection analysis also informs catalogue strategy. If customer-curated collections (e.g. "gifts under GBP 50") outperform category-based collections (e.g. "accessories"), it suggests customers respond better to use-case navigation than taxonomy-based browsing. This insight should reshape how you structure your site and create future collections.

Compare per-collection conversion rates against the store average. Collections converting significantly below average are either attracting the wrong traffic or presenting products ineffectively.

How to optimise collection performance

  1. 1

    Curate collections around customer intent

    Collections organised by use case (e.g. "work from home essentials") typically outperform pure category pages because they match how customers think about their needs rather than how your warehouse categorises products.

  2. 2

    Optimise product ordering within collections

    Place your highest-converting and best-margin products at the top of each collection. Default sort order significantly influences which products customers see and purchase.

  3. 3

    Promote high-converting, low-traffic collections

    Collections that convert well but receive little traffic are the lowest-hanging fruit. Feature them in navigation, email campaigns, and on-site banners to drive more visitors to pages that already convert.

  4. 4

    Consolidate or retire underperforming collections

    Collections with low traffic, low conversion, and minimal revenue dilute the browsing experience. Merge their products into stronger collections or remove them to simplify navigation.

  5. 5

    Refresh collections seasonally

    Update collection imagery, product assortment, and positioning to reflect seasonal trends. A static collection page signals stale inventory to returning visitors.

Shopify

Metric Definition

GMV = Number of Transactions x Average Transaction Value

Gross merchandise volume is the total monetary value of all goods sold through a marketplace, ecommerce platform, or payment processing channel over a given period. It represents the full transaction value before deducting fees, returns, discounts, and taxes. GMV is the primary scale metric for marketplaces and platforms because it captures the total economic activity flowing through the business, regardless of how much the platform retains as revenue.
