A Shopify collection page audit checks whether a shopper can narrow a product list and understand its prices before opening a card. A filter that leaves unrelated products in the grid makes the shopper check items one at a time. An unclear “From” price can make a shopper open several products before finding the option they can buy at that price.

How to run a collection page audit

Choose a populated collection, one filter you can verify, and one card with a range or “From” price. Start on your phone in the market and currency you want to test. Note which products you expect to stay and which should leave when you apply the filter. For price comparisons, use the same market and currency when you open the product page.

Tools for checking filters and prices

Use your mobile browser and a short note with the filter value, sampled product URLs, and the card price. If you use Claude or Codex with browser access, or a browser agent like Browser Use, ask it to record a few product URLs before applying the filter, after applying it, and after clearing it. Have it open the sampled price card and record the exact option and any purchase condition. Compare those observations in your own browser before filing a finding.

Add StoreSkills to your agent for a focused collection page audit. Give it the collection URL and the filter you want to test. To install the skills, run this in your terminal.

1. Prove that applying a filter changes the product list

Choose a populated collection and a filter you can verify. For a coffee collection, note one coffee you expect to stay when you choose Decaf and one you expect to leave. Apply the filter using the mobile controls, including the Apply button if there is one. Wait for the results and open a sampled card to check that it fits. If the grid count changes and the non-decaf product is still present, record its card URL and the active filter.

2. Change the selection, then clear it

Switch to a second filter value and compare which products appear. Two values can return eight items each. Check the actual cards, then remove the selection and look for an item from the original list. If the update stalls or fails, check whether the drawer communicates what happened and lets you retry. For an “In stock” filter, check what the store promises. A qualifying product can still have sold-out variants. Shopify’s guide to storefront filters

3. Open a product and return to the collection

From the filtered grid, open a product and use the browser’s Back button. Compare the active filters with the returned list. A store may restore or reset the selection. Either way, the labels, count, and products should describe the same collection state. If the screen still says “Decaf” and the grid has returned to all coffees, capture the screen before opening the card and after going back.

4. Check what the starting price actually buys

Choose a product card that shows a range or a “From” price. Open it in the same market and currency, then find the variant, pack size, or purchase option that qualifies.

Illustrative example
A card says “From $24.” The product opens on a three-pack at $54. Select the single item and see whether an available option costs $24. If you can only get that price by subscribing, check how the card communicates that condition.

5. Check the sale price and savings on the same purchase

If a card says “Save $6,” find the sale and regular prices for the same option and quantity and calculate the difference. Make sure the comparison applies in the market you’re shopping. A single bag’s sale price and a three-pack’s regular price describe different purchases. Capture the card and the matching product option together, including any discount or purchase condition.

For a filter issue, record the collection, selected value, one product that illustrates the mismatch, and what happens when you clear the filter. For a price issue, record the card label, market, and qualifying option.

After checking the collection, audit the product page on mobile. The mobile storefront audit checklist takes you through the rest of the shopping path.
