Shopify Technical SEO: The Exact Setup That Eliminates Default Issues and Unlocks Rankings

Fix 1: No-Index Tag Pages

Every time a tag is applied to a product or blog post in Shopify, the platform generates an indexable URL for that tag. A store with fifty product tags and thirty blog post tags can have eighty or more tag pages — each containing only the products or posts with that specific tag, which is a small subset of the full catalog with no unique introductory content. These pages are thin by definition and dilute the site's overall content quality signal.

The fix is robots.txt. Add Disallow directives for the tag URL patterns: /collections/*/* (which covers collection tag pages like /collections/yoga-pants/blue) and /blogs/*/tagged/* (which covers blog tag pages like /blogs/news/tagged/summer). This prevents Google from indexing these paths without breaking anything for users, who can still reach the tag pages — they just won't appear in search results.

Fix 2: Duplicate Product URLs

Shopify routes every product through two URL structures: /products/[product-slug] and /collections/[collection-slug]/products/[product-slug]. Both are valid, both serve the same page, and both can be indexed. Without consistent canonical tags, Google may index both and treat one as duplicate — or worse, split authority between them instead of consolidating it to the correct URL.

The canonical on every product page should point to the /products/ URL — the short form. Most Shopify themes handle this automatically, but theme updates and third-party apps can override canonical behavior. Verify with a Screaming Frog crawl: export all product URLs, filter by page type, and check the canonical tag column to confirm every product page is canonicalizing correctly. The Detailed SEO Chrome plugin also shows canonical tags instantly on any individual page without running a full crawl.

Fix 3: Canonical Tags on Paginated Pages

Collection pages and blog archives with more than one page of content generate pagination URLs: /collections/yoga-pants?page=2, /blogs/news?page=3. Without canonical tags, these pages can be indexed as independent thin-content pages — each showing a subset of the products or posts in the collection with no unique copy.

The correct setup: add a rel=canonical on every paginated page pointing back to the main non-paginated URL (/collections/yoga-pants). The main page should have a self-referencing canonical (pointing to itself), which Google accepts. This consolidates all authority from paginated pages to the main collection page and prevents thin pagination pages from appearing in SERPs.

Fix 4: Blog URL Redirects

Shopify's URL editing interface includes a checkbox labeled "Create URL redirect" that appears when changing a blog post or product URL. This box is checked by default — when checked, Shopify automatically creates a 301 redirect from the old URL to the new one. When unchecked, the old URL immediately returns a 404 error with no redirect.

This checkbox is the most frequently unchecked setting in the Shopify ecosystem and the source of hundreds of broken internal links on many stores. Audit by crawling in Screaming Frog and filtering for 4xx responses on internal links. Any blog post or product URL returning a 404 that previously existed needs a 301 redirect created manually in the Shopify admin under Online Store > Navigation > URL Redirects.

Fix 5: Schema Markup

Shopify themes include basic product schema (name, description, image, offers) by default. What's typically missing: aggregate rating (pulling star count and score from the review app), real-time offers data (price, availability, currency), and any organization or breadcrumb schema for the site structure.

Verify current schema rendering using Google's Rich Results Test: enter any product page URL and check which schema types are present and whether any errors exist. The highest-value addition for most stores is aggregate rating — when properly set up, star ratings appear directly in Google SERPs next to the page title, improving click-through rates by 10–30% without any change to the page's ranking position. Use a schema app like JSON-LD for SEO to fill gaps without editing theme code, or edit the theme's schema templates directly for more control.

Fix 6: Broken Internal Links

Broken internal links accumulate on every Shopify store over time. Products get removed, URLs change, collections get restructured, and the internal links pointing to old URLs are often left in place pointing to nowhere. A crawl in Screaming Frog filtered to 4xx responses on internal link sources produces a complete list of every broken internal link on the site.

Fix each broken link by either creating a 301 redirect from the old URL to the most relevant current page (the preferred fix when external links may point to the old URL) or updating the internal link to point directly to the correct current URL (the preferred fix for internal-only broken links). Once fixed, set up Google Search Console email alerts for 404 coverage errors — this catches new broken links as they appear rather than waiting for the next audit cycle to find them.

Frequently Asked Questions

Does Shopify hurt SEO compared to other e-commerce platforms?

No. Shopify is a capable SEO platform with two fixable default issues (tag page indexing, duplicate product URLs). Both are resolved in a single technical session. The platform is not the constraint for most stores — content and backlinks are.

What are the most important Shopify-specific technical SEO fixes?

In priority order: no-index tag pages (robots.txt); fix duplicate product URL canonical tags; add canonical tags to pagination pages; fix broken blog URL redirects (the 'Create URL redirect' checkbox); set up complete schema including aggregate review rating; audit and fix all broken internal links.

How long does Shopify technical SEO take to fix?

Audit: one to two hours in Screaming Frog and Search Console. Implementation: one to three hours depending on broken link volume and redirect complexity. Total: two to five hours for the initial session. After that: a five-minute monthly Search Console coverage check catches any new issues before they compound.

What is a Shopify tag page and why does it hurt SEO?

Tag pages are indexable URLs generated for every tag applied to products and blog posts — /collections/all/leather, /blogs/news/tagged/summer. They're thin pages with minimal unique content, often number in the hundreds, and consume crawl budget that should go to money pages. No-indexing them via robots.txt resolves the issue immediately.

Does Shopify handle canonical tags automatically?

Partially. Most themes add self-referencing canonicals correctly but may not consistently canonicalize both product URL formats (/products/name and /collections/collection/products/name) to the same URL. Verify with Screaming Frog or the Detailed SEO Chrome plugin — check every product page's canonical tag confirms it points to the /products/ URL regardless of which URL was crawled.
