TL;DR
Shopify auto-generates duplicate product URLs via its collection-product URL structure, and redirect chains stack silently every time you rename a handle. Both fragment link authority. Both are fixable with a structured audit. Here's exactly how to do it.
The Two Technical Issues Quietly Draining Your Shopify SEO
You didn't do anything wrong. Shopify did it for you.
Out of the box, every product in a collection gets two live, 200-status URLs:
-
/products/oak-dining-table- the canonical product URL -
/collections/dining-tables/products/oak-dining-table- the collection-scoped URL
Same page. Same content. Google sees two separate pages competing against each other. Shopify applies a canonical tag on the collection-scoped version pointing back to /products/ - but canonical tags are hints, not directives. If enough internal links or backlinks point at the duplicate version, Google may index that one instead, or split authority between both without fully consolidating either.
On top of that: redirect chains accumulate every time you rename a product handle, restructure a collection, or migrate a theme. Each hop bleeds a small amount of link authority. Over two or three years on an active store, the compounding effect is measurable.
Here's how to audit and fix both.
Part 1: Auditing Duplicate URLs
Step 1 - Crawl for collection-scoped product URLs
Run a full crawl with Screaming Frog or Ahrefs Site Audit. Filter for any URL matching the pattern /collections/[collection-name]/products/. Count how many exist and which collections they live in. On a store with 3,000 products across multiple collections, you can easily have 6,000+ URLs competing for crawl budget before you add filter parameters or pagination.
Step 2 - Verify canonical tags on every collection-scoped URL
In Screaming Frog, filter by canonical. Every collection-scoped product URL must canonicalize to its /products/ equivalent. Flag anything with a self-referencing canonical or a missing canonical - those pages are in direct competition with your canonical product pages right now.
Step 3 - Audit your internal linking
Export all internal links from the crawl. Filter for any link pointing to a collection-scoped URL. Every one of those links is fragmenting link equity instead of consolidating it on your canonical page. In most Shopify themes this is a template-level fix - update the product card or collection loop to output /products/[handle] and you resolve hundreds of instances at once.
Step 4 - Check Google Search Console
Filter your indexed pages by URL pattern. If collection-scoped URLs are appearing in your index, Google has already overridden the canonical hint - either because of a faulty implementation or because too many link signals point at the duplicate. Both scenarios require immediate action.
Part 2: Auditing and Collapsing Redirect Chains
Redirect chains form in predictable ways on Shopify stores:
- Handle renames. You rename a product for SEO. Shopify logs a 301. You rename it again six months later. That's a two-hop chain.
- Collection restructuring. Splitting "Furniture" into "Indoor Furniture" and "Outdoor Furniture" instantly chains any backlinks pointing at the old collection URL.
- Theme or app migrations. URL formatting shifts add a redirect layer if you don't collapse the previous one first.
Each hop alone isn't a crisis. The problem is Shopify has no mechanism to automatically collapse chains as they form, so they stack indefinitely.
Step 1 - Export your full redirect list
In Shopify: Online Store → Navigation → URL Redirects → Export. Stores older than two years often have several hundred rows here.
Step 2 - Identify chains
A chain exists when the destination URL of one redirect is the source URL of another. In a spreadsheet, use VLOOKUP to match destination URLs against source URLs in the same list. Any match is a chain. Screaming Frog's redirect chain report automates this and traces multi-hop paths.
Step 3 - Trace each chain to its final destination
Follow the hops until you reach a live URL. That's your target endpoint.
Step 4 - Update the original redirect to skip the hops
In Shopify's URL Redirects, edit the original redirect to point directly at the final live URL. Delete the intermediate redirects once nothing references them.
Step 5 - Update internal links pointing at redirected URLs
Any internal link that triggers a redirect wastes crawl budget and leaks authority. Update them to point directly at the current live URL.
Step 6 - Pursue backlink updates for high-authority links
For your strongest external backlinks that still point at a URL early in a chain, contact the linking site and request a link update. Not always possible - but a direct link to a live URL passes more authority than the same link firing through even one redirect hop.
Prioritization Order for Your First Audit
If you're doing this on an established store for the first time, triage like this:
- Collection-scoped URLs actively appearing in Google's index - fix canonicalization immediately
- Internal links pointing to collection-scoped URLs - template-level fix, high ROI
- Redirect chains on your highest-traffic product and collection pages
- Redirect chains connected to high-authority external backlinks
- Bulk cleanup of the remaining redirect list - work through it monthly until chains hit zero
Maintenance Cadence
- Redirect chain audit: every quarter for active stores
- Duplicate URL audit: once at the template level, then re-check after any theme update or app change that touches URL structure
The target state is simple: redirect chains at zero, 100% of internal links pointing at canonical URLs. Neither is hard to maintain after the initial cleanup. The cost of skipping it is authority fragmentation across your highest-value collection pages - the pages targeting the category keywords that actually drive revenue.
