Shopify Technical SEO Checklist: 15 Issues Holding Your Store Back

Technical SEO on Shopify is different from WordPress, Magento or any other platform because Shopify's architecture makes certain decisions for you. Some of those decisions are helpful. Others create ranking problems that are not immediately obvious unless you know what to look for. This checklist covers the fifteen technical issues that TPR Media consistently finds when auditing Shopify stores across Australia.

Our Shopify SEO service starts with a full technical audit before we build anything. Every issue on this list is something we fix in the first month of an engagement.

Canonical tag issues (the most common and most damaging)

Shopify generates duplicate URLs for every product that appears in a collection. The canonical tag is supposed to resolve this by pointing all variants to the preferred URL, but it frequently misfires.

The fastest way to audit this: crawl your store with Screaming Frog, filter by canonical, and look for mismatches between the current URL and the canonical URL. Fix the mismatches first.

URL structure issues you cannot fully control

Shopify's fixed URL prefixes (/products/, /collections/, /pages/, /blogs/) cannot be removed. Knowing this, the work is about making the best use of what you can control.

• Use descriptive, keyword-rich handles for products and collections, not auto-generated IDs or short abbreviations
• Keep handles concise but meaningful: /collections/womens-running-shoes is better than /collections/c123 or /collections/shoes-for-women-who-run
• Avoid changing handles after a store is established, every handle change is effectively a URL change that requires a 301 redirect
• Check that Shopify has not auto-generated duplicate collection slugs by appending -2 or -3 to handles

Sitemap and robots.txt audit points

Shopify automatically generates a sitemap.xml and a robots.txt file. Both have known issues.

• Shopify's sitemap includes tagged collection URLs (/collections/all?sort_by= and similar) that create thousands of near-duplicate indexed pages on stores with many tags
• The robots.txt blocks admin and checkout paths but does not block filtered collection URLs by default
• Verify your sitemap is submitted in Google Search Console and returning a 200 status code
• Check that your sitemap excludes draft, archived and hidden products
• Use Shopify's robots.txt.liquid template (available from Shopify 2.0 themes) to add custom disallow rules for parameterised URLs

In Google Search Console, check 'Pages > Not indexed > Excluded by robots.txt' and 'Crawled but not indexed'. Both reveal sitemap and crawl issues that are costing you indexation.

Schema and structured data gaps

Shopify themes vary widely in their structured data implementation. Many popular themes include Product schema, but it is often incomplete, incorrectly formatted or missing the fields Google uses for rich results.

• Product schema must include: name, description, image, offers (with price, currency, availability), and aggregateRating if you have reviews
• Missing aggregateRating means no gold stars in organic results, a significant click-through rate disadvantage
• BreadcrumbList schema improves how Google displays your result paths
• FAQ schema on high-value product and collection pages can earn expanded SERP real estate
• Validate all schema using Google's Rich Results Test before treating it as complete

Core Web Vitals, the mobile benchmark

Shopify's hosted infrastructure gives you a baseline server response time advantage over self-hosted platforms. That advantage is frequently erased by app script injection and unoptimised themes.

• LCP (Largest Contentful Paint) is usually caused by large hero or product images not served in WebP at the correct dimensions
• INP (Interaction to Next Paint) is almost always caused by heavy JavaScript from installed apps
• CLS (Cumulative Layout Shift) is caused by images without explicit dimensions, late-loading fonts and ad placements that shift content
• Run PageSpeed Insights on your homepage, a collection page and your best-selling product page, all three matter
• Check your Shopify Theme Inspector results against your PageSpeed scores to confirm which scripts are responsible for your worst metrics

Key takeaways

• Canonical tag misfires are the most common and most damaging technical SEO issue on Shopify, audit them with a crawl tool before any other work
• Shopify's sitemap includes tagged collection URLs that can create thousands of near-duplicate indexed pages on large stores
• Product schema with aggregateRating from real customer reviews enables gold stars in organic results, missing it costs click-through rate
• Core Web Vitals failures on Shopify are almost always caused by app JavaScript, not by Shopify's infrastructure itself
• URL handles cannot have their prefix removed, but choosing keyword-rich, concise handles from launch avoids costly URL restructures later

Frequently asked questions

Does Shopify need different SEO to WordPress or Magento?

Yes. Shopify has a fixed URL structure, a Liquid templating engine and unique technical quirks, including duplicate content from product variants and paginated collections, that require platform-specific fixes. Generic SEO advice applied to Shopify without understanding those constraints leaves significant ranking potential untouched.
