Ecommerce SEO Audit: The Store-Specific Checklist
by the AEO GEO Labs team6 min read
An ecommerce SEO audit is a site review focused on the problems that only online stores have: faceted navigation that creates millions of URLs, duplicate product variants, out-of-stock pages, thin category pages and product structured data. A generic audit checks titles and speed. A store audit checks whether Google can find, choose and show the right version of each product.
Start with the general process in our SEO audit guide, then use this checklist for the store-specific layer. It is grouped into crawl control, product pages, category pages and the AI search layer.
Crawl control: faceted navigation and parameters
Crawl control is the first ecommerce site audit check, because faceted navigation can generate far more URLs than a store has products. Every combination of color, size, price and brand filters can become its own URL, and search engines can waste their time crawling them.
Google's guidance on faceted navigation is direct, as of October 2026: if filtered URLs do not need to appear in search, prevent crawling them with robots.txt, or use URL fragments for filters, since Google generally does not crawl or index fragments. It describes rel=canonical and nofollow as weaker options. If some filtered pages do need to rank, Google advises standard & separators, a consistent filter order, and a 404 status for filter combinations with no results.
Check:
- Crawl the site and count unique URLs against the number of products and categories. A ratio far above that suggests parameter bloat.
- Review Search Console's Page indexing report for large counts of "Crawled, currently not indexed" or "Discovered, currently not indexed" on parameter URLs.
- Decide which filter pages deserve to rank (for example "red running shoes") and give them clean, linkable URLs. Block or fragment the rest.
- Confirm sort orders, session IDs and tracking parameters are not creating crawlable duplicates.
Use our robots.txt tester to confirm your rules block the parameters you intend and nothing else.
Product page audit
A product page audit checks that each product has one canonical URL, unique content, complete structured data and a sensible fate when it goes out of stock. These pages carry most of a store's buying intent.
Variants and duplicates. Products sold in several colors or sizes often produce a URL per variant with near-identical content. Pick one approach: either one canonical product URL with variant selectors, or separate indexable variant pages that each have distinct content and demand. Google's documentation on consolidating duplicate URLs explains how canonical signals work.
Manufacturer descriptions. Copying the supplier's description means your page says the same thing as every other retailer selling the item. Rewrite descriptions for your top sellers first, adding sizing notes, use cases and answers to the questions your support team hears.
Out-of-stock products. Decide a rule and apply it consistently:
| Situation | Usual approach |
|---|---|
| Temporarily out of stock | Keep the page live, mark availability correctly, show a restock date or alternatives |
| Permanently discontinued, with a close replacement | 301 redirect to the replacement product |
| Permanently discontinued, no replacement | Return 404 or 410, or keep the page live if it still earns links or traffic, with clear alternatives |
Product structured data. Google distinguishes two kinds of product rich results. Its product structured data documentation describes product snippets for pages where people cannot buy directly, and merchant listings for pages where they can, with details such as price, availability, shipping and returns. Check that markup matches the visible price and stock status. Our structured data checker shows what each page currently outputs.
Images and speed. Product images drive conversions and image search. Check file sizes, descriptive file names, alt text and that the main image is not lazy-loaded above the fold.
Category page audit
A category page audit checks that each category targets a distinct search, has enough unique content to deserve ranking, and links properly to its products. Category pages often rank for the broadest, highest-value terms in a store.
Check:
- One category per intent. Two categories competing for "men's running shoes" split signals. Merge or differentiate them.
- Useful copy. A short intro that helps buyers choose (fit, materials, who it suits) beats a keyword-stuffed block at the bottom.
- Pagination. Google's pagination guidance for ecommerce recommends that each paginated page has its own URL and that you link pages sequentially. Products deep in a "load more" button that never creates a crawlable link may never be found.
- Internal links. Top sellers and new categories should be reachable within a few clicks of the home page.
- Empty categories. Categories with zero or one product look thin. Merge them until there is real inventory.
The AI search layer of an ecommerce SEO audit
The AI search layer of an ecommerce SEO audit checks whether AI engines can read your product data and whether third-party sources describe your products accurately. Shoppers increasingly ask ChatGPT, Perplexity and Google AI Mode for product recommendations before they search a store directly.
Check that product details such as price, materials and dimensions appear as plain text in the server-rendered HTML, not only after JavaScript runs. Check that your robots.txt is not blocking AI crawlers you want to allow. Then look outside your site: AI answers are assembled from many sources, often including reviews, comparison articles and forums, so what other sites say about your products is likely to matter as much as your own pages.

Frequently asked questions
What is an ecommerce SEO audit?
An ecommerce SEO audit is a review of an online store's search performance that adds store-specific checks to a standard audit. It covers faceted navigation and parameter URLs, duplicate product variants, out-of-stock handling, product structured data, category page content, pagination and internal linking. The goal is that search engines find, index and show the right version of every product and category.
How do I audit faceted navigation for SEO?
Crawl the site and compare the number of URLs with your real product and category count. Check Search Console for many unindexed parameter URLs. Then decide which filter pages deserve to rank and give them clean URLs. As of October 2026, Google recommends blocking the remaining filter URLs with robots.txt or using URL fragments, rather than relying only on canonical tags.
Should out-of-stock product pages be removed?
Not automatically. Keep temporarily unavailable products live with accurate availability and alternatives. Redirect permanently discontinued products to a close replacement when one exists. When no replacement exists, return a 404 or 410, unless the page still earns traffic or links, in which case keep it live and point visitors to related products.
What does a product page audit check?
A product page audit checks canonical URLs for variants, unique product descriptions, product structured data that matches the visible price and stock, image size and alt text, page speed, internal links from categories, and reviews. For top sellers, it also checks that the page answers common buyer questions in plain text near the top.
How often should an online store run an SEO audit?
Run a full ecommerce SEO audit once a year and before any platform migration or redesign. Run automated crawls weekly or monthly, because stores add and remove products constantly, and new filters or apps can create URL bloat overnight. Check Search Console's indexing and rich results reports every month.
