Shopify Store Health Checklist: 10 Data Issues Slowing Down Your Store

Most Shopify merchants assume their store is in good shape because orders are coming in. But quietly, in the background, a handful of product data problems are costing them — in conversions, in ad spend, in margin, and in organic rankings. A missing cost field here, a duplicate tag there, a few hundred products without descriptions — none of it feels urgent until you add it up.

This checklist covers the 10 most common product data issues found in Shopify stores with 100+ SKUs. Go through it once a quarter. Fix what you find. Your store will perform better for it.

1. Products Without a Cost Per Item

If you haven't entered the cost per item for your products, Shopify can't calculate your margin — and neither can you. This is the single most important data field for running a profitable store. Without it, you're pricing by gut feel.

How to check: In Shopify admin, filter products and look for blank cost fields. Ideally, every active product (and every variant) should have a cost entered.

Why it matters: If your Lodge cast iron skillet costs you $28 and you're selling it for $44, that's a 36% margin. If you don't have the cost entered, you might run a "20% off" sale and drop to a $35 sale price — now you're making $7 on a product that costs you $28 to acquire. That's a 25% gross margin. Better, but not what you intended. Without cost data, you can't know.

2. Active Products With No Description

Product descriptions do two jobs: they help Google understand what you're selling, and they help shoppers decide to buy. A blank description field fails at both.

How to check: Export your products to CSV and filter for rows where the Body (HTML) column is empty. Or use a bulk editor that surfaces this as a filter.

Why it matters: Google's product listings pull from your description. No description means lower relevance scores, lower organic visibility. For paid search, low-quality product data leads to lower Quality Scores and higher CPCs. It compounds.

3. Missing Product Images

Products without images don't convert. Full stop. On mobile — where most DTC traffic happens — a blank image slot reads as broken or untrustworthy.

How to check: In Shopify admin, go to Products and sort by Image. Products with no image appear at the top or bottom depending on sort direction. Alternatively, look for a product count in your data quality tooling.

Why it matters: A Patagonia Nano Puff jacket with no image is going to get scrolled past, regardless of how good the description or price is. Images are the first conversion lever.

4. Missing or Inconsistent SKUs

SKUs matter for inventory reconciliation, purchase orders, and channel sync (Google Shopping, Amazon, etc.). Stores that have grown fast through manual product creation often have large gaps — some products have SKUs, others don't, and the format is inconsistent across vendors.

How to check: Filter your product export for blank SKU fields at the variant level (not just the product level — SKUs live on variants).

Why it matters: If you're syncing to Google Merchant Center, missing SKUs can cause feed rejections. If you're running purchase orders with suppliers like Carhartt or Stanley, mismatched SKUs create fulfillment headaches.

5. Low-Margin Products Hiding in Your Catalog

Most merchants know their top sellers. Few know which products are actively dragging down their average margin. Low-margin products are the ones your ad spend promotes, your team picks, and your warehouse ships — often at a loss once you factor in returns, shipping, and overhead.

How to check: Sort your products by margin ascending. Any product under your target threshold (typically 30–40% for DTC) deserves a review.

Concrete example: If your Yeti Rambler costs you $22 to buy and you're selling it at $30, that's a 27% margin — below most DTC targets. You have two choices: raise the price to ~$31.50 (to hit 30%) or remove it from paid promotion channels entirely. Either way, you need to know it's a problem first.

6. Duplicate or Conflicting Tags

Shopify tags are used for collection rules, discounts, and app logic. When tags drift — sale vs Sale vs on-sale — your automated collections break, discount eligibility gets inconsistent, and filtering becomes unreliable.

How to check: Export products and review the Tags column for case variations and near-duplicates. Common culprits: new-arrival vs new_arrival vs New Arrival.

Why it matters: If your "Summer Sale" collection is driven by a summer-sale tag, any product tagged summer_sale won't appear in it — silently excluded from a promotion you thought was comprehensive.

7. Products Without a Vendor Set

The Vendor field is one of Shopify's most underused organizational tools. It enables vendor-level reporting, supplier-based filtering in the admin, and cleaner purchase order workflows. Stores that import from multiple suppliers (Allbirds, Cotopaxi, or any wholesale brand) and leave this blank are making their own operations harder than they need to be.

How to check: Filter products where Vendor is blank or set to your store name as a catch-all.

8. Incorrect or Missing Weights and Dimensions

If you use calculated shipping rates, wrong weights mean you're either overcharging customers (bad for conversion) or subsidizing shipping on heavy products (bad for margin). Dimensional weight matters too for UPS/FedEx — a lightweight but bulky item will get rated on its dimensional weight, not its actual weight.

How to check: Sort products by weight. Products at 0 or at suspiciously round numbers (exactly 1 lb for every product in a category) are likely guesses or placeholders.

9. Out-of-Stock Products That Are Still Active

Products that are out of stock but still showing as active with a buy button are a conversion problem. Customers add to cart, hit the checkout, and bounce when they realize the item is unavailable. Or worse — they complete the order and you have to cancel it.

How to check: Filter for products with inventory at 0 that are set to "Continue selling when out of stock" — these are the ones to audit. Decide: restock soon, draft them, or archive.

10. No Compare-At Price on Sale Items

The compare-at price is what creates the visual strike-through on your storefront — showing the original price crossed out next to the sale price. Without it, your discounted products don't communicate value. Customers see $49 and think that's just the price. With a compare-at of $69, they see a $20 saving.

How to check: If you run regular sales or promotions, verify that discounted products have compare-at prices set. A bulk editor can surface which products are priced below a threshold but lack a compare-at value.

How Often Should You Run This Checklist?

For stores under 500 SKUs, a monthly pass is usually enough. For larger catalogs — especially those adding products frequently — run it weekly or set up automated alerts so you catch issues as they're created, not three months later when you're preparing for a major sale.

Issue	Priority	Revenue Impact
Missing cost per item	Critical	Margin visibility
No description	High	SEO + conversion
Missing images	High	Conversion
Missing SKUs	High	Ops + channel sync
Low-margin products	High	Profitability
Duplicate tags	Medium	Collection logic
Missing vendor	Medium	Ops efficiency
Wrong weights	Medium	Shipping margin
Out-of-stock active	Medium	Conversion + ops
No compare-at price	Low–Medium	Perceived value

The Fastest Way to Fix These at Scale

Running this checklist manually across a catalog of 500+ products is a multi-hour spreadsheet exercise. The practical approach for most merchants is to use tooling that surfaces these issues automatically — so instead of hunting, you're fixing.

BulkOps flags all ten of these issues in its Data Insights dashboard. You can see exactly how many products have each problem, filter to just those products, and fix them in bulk — updating descriptions, adding costs, or cleaning up tags across your entire catalog in one pass rather than product by product.
