Technical SEO Audit for Shopify: Common Issues & How to Fix Them

Technical SEO ensures search engines can efficiently crawl, index, and understand your site. On Shopify, several platform-specific issues need attention—especially as your store grows beyond a handful of products.

How to Audit Your Shopify Store

A thorough technical audit combines three approaches:

1. Manual review — Check key pages yourself for obvious issues.
2. Crawl analysis — Use a tool like Screaming Frog or Sitebulb to crawl your entire site.
3. Google Search Console — Review Coverage, Experience, and Enhancements reports.

Common Shopify Technical SEO Issues

Non-Canonical Internal Product Links

By default, Shopify themes often link to products through collection URLs: `/collections/shoes/products/running-shoe`. The canonical URL is `/products/running-shoe`. This creates duplicate crawl paths and wastes budget.

Fix: Edit your theme's product grid snippet. Remove the `within: collection` parameter so product links always point to `/products/handle`.

Missing or Broken Breadcrumbs

Once you fix internal product links, default breadcrumbs may break because they relied on the collection context. Use a product metafield (e.g., "breadcrumb") to store the primary collection handle, then reference it in your breadcrumb template:

```liquid <a href="{{ collections[product.metafields.global.breadcrumb].url }}"> {{ collections[product.metafields.global.breadcrumb].title }} </a> ```

Product Tag Pages

Product tags create URLs like `/collections/perfume/125ml`. These are thin pages—same title, same description, fewer products. Multiply that across every collection and tag, and you can have thousands of low-value pages in your index.

Fix: Add a noindex meta tag for tag pages in your theme:

```liquid {% if current_tags %} <meta name="robots" content="noindex, follow"> {% endif %} ```

Then block them in robots.txt: `Disallow: /collections/*/*`

Blog Tag Pages

Same issue as product tags. Blog tags at `/blogs/news/tagged/tag-name` generate thin duplicate content.

Fix: Same approach—noindex via Liquid and optionally block in robots.txt: `Disallow: /blogs/*/tagged/*`

Vendor and Product Type Collections

Shopify auto-generates pages at `/collections/vendors?q=Name` and `/collections/types?q=Name`. These are thin, unoptimized pages.

Fix: Noindex these pages and block them in robots.txt. If certain brands deserve SEO attention, create proper manual collections with unique descriptions.

Other Default Pages

Pages like `/collections/all`, `/collections`, and `/collections/new` are often thin or redundant. Noindex them unless they serve a specific purpose.

Setting Up a Custom Robots.txt

Shopify allows customizing robots.txt through a Liquid template. Add it via Online Store > Themes > Edit Code > Add template > robots.txt.

A typical addition for the `*` user agent:

```liquid {%- if group.user_agent.value == '*' -%} {{ 'Disallow: /collections/all*' }} {{ 'Disallow: /*?q=*' }} {{ 'Disallow: /collections/*/*' }} {{ 'Disallow: /blogs/*/tagged/*' }} {%- endif -%} ```

Warning: `Disallow: /collections/*/*` also blocks product URLs accessed through collections. Only use this after fixing internal product links to point directly to `/products/handle`.

Structured Data

Implement these schema types for rich results:

• Product pages: Product, Offer, AggregateRating, BreadcrumbList
• Blog posts: Article/BlogPosting, BreadcrumbList
• Homepage: Organization, WebSite (with SearchAction)
• Collections: BreadcrumbList, optionally FAQPage

Validate with Google's Rich Results Test. See our dedicated structured data guide for implementation details.

Canonicalization and Redirects

• Canonicalize product variants that are thin or duplicate. Use a metafield-based canonical URL for child products.
• 301 redirect deleted products to the most relevant collection or replacement product. Use Online Store > Navigation > URL Redirects.

Removing Pages from the Sitemap

Shopify does not let you edit the sitemap directly. The `seo.hidden` metafield removes a page from the sitemap but also adds a noindex meta tag. If you only want sitemap removal, strip the noindex with a Liquid workaround in your theme.

Google Search Console Review

After your crawl and fixes, check GSC for:

• Coverage issues: 404s, noindexed pages you expected to be indexed, soft 404s.
• Enhancements: Structured data errors, breadcrumb issues.
• Core Web Vitals: Speed and interaction metrics.

Priority Order

For stores with 100+ products, tackle these in order: fix internal product links first (highest impact), then tag/vendor/type pages, then breadcrumbs and structured data. For smaller stores, the impact of technical SEO is proportionally smaller—focus on content and on-page SEO instead.
