E-commerce SEO audit: what to check, in the order that pays off

Most SEO audits deliver a spreadsheet with hundreds of rows, sorted by tool rather than by stakes. On an e-commerce site, that is the best way to spend six months fixing details while the pages that sell remain under-optimized. Here is a checklist ranked in the order that pays off.

1. Measure where the money is

Before looking for problems, look at the split of your organic traffic by landing page type: categories, facets, product pages, content, homepage. Then the revenue of each group. This segmentation, detailed in our analysis of e-commerce SEO traffic, guides the rest of the audit: if 80% of SEO revenue comes through categories, that is where the audit must dig.

2. Indexing

• Are the important pages indexed? Search Console Pages report: categories under "Detected, currently not indexed" or "Excluded by noindex tag".
• Are useless pages excluded? Sort filters, facet combinations with no demand, internal search, account pages.
• Are canonical tags consistent? A category whose canonical points elsewhere asks Google to ignore it.
• Does the sitemap contain only indexable pages responding in 200?

3. Category pages

For each strategic category: an identified primary query, a clear H1, a specific title tag and meta description, useful copy, a product list visible in the HTML, crawlable pagination. The full checklist is in our guide to optimizing a category page.

4. Facets

• Which combinations have real demand and are not indexed? That is missing revenue.
• Which valueless combinations are crawled or indexed? That is wasted crawl budget.
• Do indexed facets have their own tags, or the parent category's?

See our guide to faceted navigation.

5. Tags at scale

Export the title tags and meta descriptions of all indexed pages and look for:

• duplicates: the same tags on several pages;
• templates: the same formula declined with a variable;
• gaps: empty meta descriptions, title tags reduced to the category name;
• rewrites: on your main queries, does Google display your title tag?

This is often the largest workstream, and the one whose effect on click-through rate is fastest.

6. Cannibalization

In Search Console, spot the important queries for which several of your pages receive impressions, with a position that fluctuates. See our guide to cannibalization.

7. Internal linking

Do strategic categories and facets receive enough internal links? Are there orphan pages, links to redirects or errors? Do blog articles link back to categories? See our guide to internal linking.

8. AI Overview exposure

New item since July 2026: what share of your traffic goes through queries where Google displays an AI Overview? In our study of 599 French queries, it appears on 70% of informational queries but 9% of transactional ones. A site heavily dependent on its blog is more exposed than a site carried by its categories.

9. International

If the site exists in several languages: one URL per language, reciprocal hreflang tags, no automatic redirect based on IP, and tags written for local queries rather than translated. See our guide to international SEO.

10. Basic technical setup

Mobile speed, server errors, redirect chains, blocked resources. These points matter, but on most recent e-commerce sites, they weigh less than points 2 to 6.

From findings to action

An audit is only worth the action plan that follows it. Sort each workstream by two criteria, potential revenue and effort, and start with high-potential, low-effort workstreams. On most sites, the tags and copy of categories and facets come first: high potential, but significant effort by hand. That is the workstream unblind automates, with the quality controls described in our guide to category SEO copy.
