Ecommerce sites break SEO tools in ways smaller sites don’t — thousands of product pages, filtered URLs multiplying endlessly, and category pages that need to both rank and convert. This checklist covers the ecommerce-specific issues a general SEO audit often misses.
Product Page Checklist (8 Points)
- Check for duplicate or near-duplicate product descriptions, particularly supplier-copied text used across multiple listings or even multiple competing sites.
- Confirm every product has unique title tags and meta descriptions — templated tags with only the product name swapped out are a common ecommerce SEO gap.
- Add product schema markup (price, availability, reviews) so listings are eligible for rich results.
- Check for out-of-stock and discontinued products still being indexed and wasting crawl budget — decide on a clear policy (redirect, noindex, or keep live with alternatives shown).
- Confirm canonical tags are correct on any product available in multiple categories or variants (size, colour), to avoid duplicate content competing against itself.
- Review product image alt text for genuine descriptiveness, not just the file name.
- Check page load speed on product pages specifically — these are often the heaviest pages on an ecommerce site due to image galleries and third-party review widgets.
- Confirm breadcrumb navigation and schema are implemented correctly on every product page.
Category Page Checklist (6 Points)
- Confirm every category page has genuine supporting content, not just a product grid — thin category pages struggle to rank against competitors with real content.
- Audit faceted navigation (size, colour, price filters) for duplicate content and crawl budget waste — confirm filtered URLs are either canonicalised, noindexed, or parameter-handled correctly.
- Check category page title tags and headings for keyword relevance beyond just the category name.
- Review internal linking from category to product pages and between related categories.
- Confirm pagination is handled correctly (rel=next/prev where relevant, or a “load more” pattern that doesn’t hide content from crawlers).
- Check that category pages aren’t competing with each other for the same keyword due to overlapping or poorly structured taxonomy.
Technical & Platform Checklist (8 Points)
- Run a full crawl and check crawl budget usage — large ecommerce sites can waste significant crawl budget on filtered URLs, out-of-stock pages, and internal search result pages.
- Check Core Web Vitals specifically on product and category templates, not just the homepage.
- Confirm site search results pages are noindexed — these should almost never be allowed to index.
- Check for broken links and redirect chains, particularly from discontinued products.
- Confirm the XML sitemap reflects current, live products and excludes out-of-stock or removed items.
- Review robots.txt for any accidental blocking of category or product paths.
- Check platform-specific issues — Shopify and WooCommerce each have known technical quirks (URL structure, variant handling, app bloat) worth checking against current best practice for your specific platform.
- Validate structured data using Google’s Rich Results Test across a sample of product and category pages.
Conversion & Search Behaviour Checklist (4 Points)
- Review internal site search data for what customers are actually searching for once on the site — genuine insight into content and product gaps.
- Check that high-value category and product pages have clear calls to action above the fold.
- Confirm reviews and ratings display correctly and feed into product schema.
- Track conversion rate by landing page, not just traffic, since ecommerce SEO should be judged on revenue impact, not visits alone.
What to Fix First
If you can only tackle a handful of items this month: fix duplicate product content and faceted navigation indexing first (the two biggest sources of ecommerce-specific technical debt), then move to product schema and category page content depth, which tend to have the most direct ranking impact once the technical foundation is sound.
Frequently Asked Questions
How is an ecommerce SEO audit different from a general SEO audit?
A general SEO audit covers site-wide technical and on-page fundamentals. An ecommerce audit adds scale-specific checks — faceted navigation, product schema, duplicate product content, and platform-specific issues — that only apply to sites with large product catalogues.
How often should an ecommerce site run a full SEO audit?
At least twice a year, or after any major platform change, catalogue expansion, or unexplained traffic drop — ecommerce technical debt accumulates faster than on smaller sites given the sheer number of pages.
Can I run this checklist myself, or do I need a specialist?
Much of it is genuinely DIY-friendly with the right tools (Google Search Console, a crawler, Google’s Rich Results Test). Faceted navigation and crawl budget issues in particular often benefit from specialist review given how platform-specific the fixes can be.
Does this apply to Shopify and WooCommerce equally?
The core checklist applies to both, though the specific technical fixes differ — see our Ecommerce SEO Services page for platform-specific detail.
What’s the single highest-impact fix on this list?
For most stores, resolving faceted navigation duplicate content — it’s the issue most likely to be silently wasting crawl budget and diluting ranking signal across near-identical URLs.
