Ecommerce SEO is harder than standard SEO. You are dealing with hundreds or thousands of product and category pages, filters that spawn endless URLs, out-of-stock items, and duplicate content that appears without you doing anything. An ecommerce SEO audit finds where all of that is bleeding rankings and revenue. This checklist is built specifically for online stores, and it pairs with our general SEO audit checklist for the fundamentals.
Quick answer: An ecommerce SEO audit focuses on six store-specific areas: crawl budget and faceted navigation, indexation of product and category pages, product and category page optimisation, ecommerce schema, site structure and internal linking, and handling of out-of-stock and duplicate products.
1. Crawl budget and faceted navigation
Large stores waste crawl budget on low-value URLs. This is the number one ecommerce SEO problem.
|
Check |
What to look for |
|
Faceted URLs |
Filters and sorting should not create thousands of crawlable, indexable URLs |
|
Parameter handling |
Control filter, sort and pagination parameters |
|
Crawl budget |
Googlebot spends time on important pages, not endless variants |
|
robots.txt rules |
Block low-value filtered paths where appropriate |
|
Internal search pages |
Keep internal site-search results out of the index |
2. Indexation of products and categories
The right pages, and only the right pages, should be indexed.
- Category pages indexed: your money pages are indexed and ranking.
- Product pages indexed: important products are discoverable in search.
- Thin or empty categories: noindex or improve near-empty category pages.
- Index bloat: remove low-value variant, tag and filter pages from the index.
- Canonical tags: product variants point to a single canonical version.
3. Product page SEO
Product pages are where the sale happens, so optimise them properly.
|
Element |
Best practice |
|
Titles and H1 |
Include product name plus key attribute and intent |
|
Unique descriptions |
No manufacturer copy pasted across the web |
|
Images |
Descriptive alt text, compressed, multiple angles |
|
Reviews |
Genuine reviews on the page for content and trust |
|
Internal links |
Link to related and complementary products |
|
Out-of-stock logic |
Keep and optimise pages for products returning to stock |
4. Category page SEO
Category pages often have the highest ranking potential, yet are the most neglected.
- Intro content: add useful, keyword-relevant copy to key category pages.
- Clear H1 and titles: target the category’s main search term.
- Logical structure: subcategories and filters that match how people search.
- Internal linking: link from navigation and content to priority categories.
- Pagination: handle multi-page categories cleanly so all products are reachable.
5. Ecommerce schema and rich results
Structured data wins more visible, higher-converting listings.
- Product schema: price, availability and currency on every product.
- Review and rating schema: to earn star ratings in results.
- Breadcrumb schema: reflect your site structure in the SERP.
- Organisation and site search schema: for brand and sitelinks.
- Validation: test all markup and fix errors and warnings.
6. Site structure and internal linking
Structure decides how authority flows to your money pages.
- Flat architecture: important products are a few clicks from the homepage.
- Logical hierarchy: home, category, subcategory, product.
- Internal links: guide authority and shoppers toward priority products.
- Breadcrumbs: help users and search engines understand the hierarchy.
- Orphan pages: find and link to products with no internal links.
7. Duplicate and out-of-stock content
Ecommerce generates duplication and dead pages constantly.
- Duplicate products: consolidate near-identical items or use canonicals.
- Similar descriptions: rewrite so variants are not thin duplicates.
- Out-of-stock: keep, redirect or update depending on whether the product returns.
- Discontinued products: 301 redirect to the closest relevant page, do not leave 404s.
- Seasonal pages: keep evergreen category URLs live year-round to retain authority.
8. Technical health, speed and mobile
Ecommerce sites are heavy, so performance is critical.
- Core Web Vitals: pass on mobile, where most shoppers are.
- Page speed: compress images, lazy-load, and trim scripts.
- Mobile checkout: fast, simple and touch-friendly.
- HTTPS and security: secure across the whole store and checkout.
- Broken links and redirects: fix chains that slow crawling and users.
A slow store undoes good SEO, which is why build quality and SEO belong together. See our ecommerce web development approach.

Frequently asked questions
How is ecommerce SEO different from regular SEO?
Ecommerce SEO adds store-specific challenges: managing crawl budget across thousands of URLs, faceted navigation, product and category optimisation, ecommerce schema, and out-of-stock handling that standard sites never face.
What is the biggest ecommerce SEO mistake?
Letting filters and sorting create thousands of indexable URLs, which wastes crawl budget and buries the pages that matter.
Should out-of-stock product pages be deleted?
Usually no. Keep and optimise them if the product returns, and 301 redirect permanently discontinued products to a relevant page rather than leaving a 404.
How often should I audit an ecommerce site?
A full audit twice a year, with monthly checks on indexation, Core Web Vitals and top category and product rankings.
