Before building CatalogFix, we scanned a few hundred Shopify storefronts to see what was actually broken on real product pages. We expected to find a long tail of weird edge cases. Instead, the same five mistakes showed up almost everywhere, in roughly the same order.

This is the short list. Fix these and most Shopify stores end up in the top quartile for product page quality in their niche.

1. Blank SEO fields

The single most common mistake. The merchant launched the store, the products work, the SEO title and SEO description fields are empty across the catalog. Shopify quietly falls back to defaults, the storefront renders fine, and nobody notices.

The cost is real. An empty meta description means Google constructs your search snippet from random page content. An empty meta title means your product page shows up as {product title} – {store}, which rarely matches how shoppers actually search.

Fix: open ten random products in your admin. Check the Search engine listing section on each. If more than three are blank, the gap is real and worth a bulk pass. Full breakdown in Why most Shopify stores have blank SEO fields.

2. Missing image alt text

A close second. About 70% of the Shopify catalogs we scanned had alt text on fewer than half their product images. Many had alt text on zero images.

This is the field most merchants forget exists. It sits inside the “Edit alt text” dialog on each image, three clicks deep, repeated for every image. Bulk-filling it by hand on a 200-product catalog with 4 images per product means 800 dialog edits. Nobody does that voluntarily.

The cost: lost Google Image Search traffic (sometimes 10–30% of a visual-product store’s organic traffic) and accessibility failures (screen reader users get “image, image, image” instead of product details).

Fix: at minimum, fill in alt text on your hero product image for every product. That alone closes most of the SEO gap on a typical store. Full breakdown in Image alt text on Shopify: the SEO and accessibility win most merchants miss.

3. Generic, padded product descriptions

This one looks different from store to store, but the pattern is the same. The product description opens with a generic welcome, spends two paragraphs on brand backstory, lists features in a wall of prose, and never quite answers the question the shopper is actually asking.

The test: read the first sentence of your product description out loud. If it could be copy-pasted onto another product on your store with no changes, the sentence is doing no work. If it could be copy-pasted onto a competitor’s product, the entire opening paragraph is doing no work.

The fix is structural. First 50 words should answer what the product is, what it’s for, and why it’s good. Bullet points for concrete features. One paragraph of context if it adds something. Specifications block at the bottom. Most product descriptions should land under 200 words.

4. Inconsistent product titles

Less obvious than the first three, but it shows up reliably once you start looking. A typical Shopify catalog has product titles in three or four different formats, depending on which person added the product and when.

Examples from one catalog we scanned:

  • Black Cotton Hoodie
  • Hoodie - Black - Heavy
  • Northwood Goods | Premium Black Hoodie 14oz
  • Heavyweight Hoodie (Black)

Same store. Same product category. Four different naming conventions. This hurts in three ways:

  • Site search and filtering breaks (Shopify’s storefront search treats these as four totally different products).
  • Meta title fallbacks become inconsistent across the catalog.
  • Shoppers landing on multiple product pages get a confusing brand impression.

Fix: pick one product title format and apply it across the catalog. A good default for most apparel and goods stores is [Adjective] [Product] in [Color/Variant], e.g. “Heavyweight Cotton Hoodie in Black”. For supplements or technical goods, [Brand] [Product] [Spec] works better. Bulk-edit using Shopify’s native bulk editor or Matrixify.

5. Tag chaos

The Shopify tags field is invisible to shoppers but used heavily under the hood. Collections, navigation filtering, related products, automated workflows, and analytics all rely on tags.

The default state of tags across most Shopify stores is chaos. Tags like Black, black, BLACK, colour-black, color/black, and noir all exist on different products. Tags get added during product creation, never reviewed, and accumulate over years until the tag list has 500+ entries and nobody knows what’s used where.

The cost: collections break (a smart collection rule based on Black won’t pick up products tagged black), filtering breaks (storefront filters built on tags show duplicates or miss products), and the SEO impact is uncertain (tags don’t directly help SEO but they do show up in URL slugs for tagged collection pages, and inconsistency there hurts).

Fix: export your products to CSV (Shopify admin → Products → Export). Open the Tags column in a spreadsheet. Count unique values. Decide which to keep, which to merge, which to delete. Reimport. Or use a tag-management app like Smart Tag Manager for ongoing hygiene.

This is the one mistake on this list that mostly doesn’t help SEO. But it makes the store run cleaner, and that’s worth doing once.

What to fix first

The order most merchants should follow:

  1. SEO fields (mistake #1). Highest impact on organic traffic. Bulk-generate meta titles and meta descriptions across the catalog.
  2. Alt text (mistake #2). Second-highest impact, especially for visual product categories. Plus the accessibility upside.
  3. Product descriptions (mistake #3). Slower to fix but the conversion lift is the biggest. Start with your top-20 products by revenue.
  4. Product titles (mistake #4). Once. Then leave it alone.
  5. Tags (mistake #5). Worth doing, lowest direct SEO impact. Do this when the others are fixed.

Most merchants try to fix everything at once, get overwhelmed, and finish nothing. Fix one category at a time, ship the changes, see the impact, move on.

Mistakes 1, 2, and 3 are exactly what CatalogFix bulk-fixes. Scan the catalog, score it out of 100, and generate the missing meta titles, meta descriptions, and image alt text. Bulk-generate product descriptions too if you want, or leave yours alone and just fill the gaps. Review every change before publishing. Install on the Shopify App Store.
