Ecommerce SEO Audit: What Should Be Included? 10 Checks

Last reviewed: November 2026

An ecommerce SEO audit should examine 10 things: indexation, URL structure, faceted navigation, structured data, thin content, internal linking, pagination, Core Web Vitals, out-of-stock handling, and measurement. If your audit skips any of these, it is not really an ecommerce SEO audit.

This guide is for store owners and marketing leads who want to know what a real ecommerce SEO audit covers before they pay for one. It applies to Shopify, WooCommerce, and custom storefronts alike. Prefer to have it done for you? Our ecommerce SEO services start with exactly this 10-check review.

What makes an ecommerce SEO audit different from a regular SEO audit?

A regular SEO audit looks at a site’s general health: titles, meta descriptions, broken links, speed. An ecommerce SEO audit goes deeper into store-specific problems, faceted navigation, product variants, thin product content, and structured data for merchant listings, because those are the issues that actually sink online stores.

Check 1: Are your product and category pages actually indexed?

Every ecommerce SEO audit starts with indexation, because a product page Google has not indexed cannot rank no matter how good it looks.

Open Google Search Console and compare indexed product pages against the products you actually sell. Large catalogs often show a gap: pages reported as “Crawled, currently not indexed” or “Discovered, currently not indexed.” The usual cause is orphaned products, pages with no internal links, which Google finds late or never.

Google’s guidance is direct: link to every product you want indexed. If the catalog is too large to link fully, cover the gap with an XML sitemap or a Google Merchant Center feed. A real audit names the missing products and templates, not just a total.

Check 2: Is your URL structure creating duplicate product pages?

Your ecommerce SEO audit should check whether the same product loads under several different URLs, because Google may treat those as separate pages, crawl them all, and discard some as duplicates.

Minimize alternative URLs that return the same content. Use descriptive paths, like /product/black-t-shirt-with-a-white-collar instead of /product/3243. Write parameters as ?key=value, and never put session IDs, tracking codes, or the current time in URLs.

Variants get special attention. Google recommends each variant be identifiable by a separate URL, a path segment like /t-shirt/green or a query parameter like /t-shirt?color=green, with the canonical set to the URL with the variant parameter omitted. One detail many stores miss: Google ignores fragments, so /product/t-shirt#black and /product/t-shirt#white count as the same page.

Check 3: Is faceted navigation wasting your crawl budget?

Faceted navigation is the filter sidebar on category pages, and an ecommerce SEO audit must check it, because its URL parameters can generate thousands of near-duplicate URLs that burn through Google’s crawl budget.

Google documents two harms: overcrawling, where crawlers fetch huge numbers of filter URLs before concluding they are useless, and slower discovery, where time spent on useless URLs delays finding your new products. Picture a store with 400 products and color, size, brand, and price filters on every category. Those filters can combine into tens of thousands of URLs. When new products take weeks to appear in Google, this is usually why.

Google’s recommended fix: disallow filter parameters in robots.txt, for example disallow: /*?*color=, while keeping product pages and one unfiltered listing crawlable. URL fragments are an alternative with no crawl impact. Canonicals help over time but are, in Google’s words, generally less effective in the long term. Dead combinations should 404.

Check 4: Does your product structured data qualify for rich results?

An ecommerce SEO audit validates product structured data, because correct markup makes products eligible for rich results and variant displays in Google’s merchant listing experiences.

For stores selling variants, Google’s product variant documentation describes the ProductGroup approach: group variants with hasVariant, declare what varies with variesBy, and identify the group with productGroupID. Each variant needs a unique ID (sku or gtin) and its own URL. On single-page sites, there must still be one canonical URL for the whole group, typically the base URL with no variant preselected.

Validate markup with Google’s Rich Results Test and check how Google sees the page with the URL Inspection tool. Price and availability in the markup must match what shoppers see.

Check 5: Is your product content thin or copied from the manufacturer?

Your ecommerce SEO audit should flag product pages with thin or manufacturer-copied descriptions, because pages need original, useful content to stand a chance in search.

Google’s helpful, people-first content guidance applies to stores too. A product page that repeats the manufacturer’s 40-word description gives Google no reason to prefer it over the hundred other stores using the same text. Sample pages across templates and check for uniqueness: real specs, compatibility notes, use cases, honest pros and cons, and customer questions answered in your own words.

Category pages deserve the same check. A category that is only a grid of thumbnails with no intro copy is a thin page. One short, genuinely useful paragraph about what the category covers and how to choose is often enough to change that.

Check 6: Can shoppers and Google reach every product through links?

An ecommerce SEO audit traces the link path to your products, because Google discovers pages by following links, and deep or orphaned products get crawled late or never.
