E-commerce SEO audit: the 12 points to check before any content strategy

Of the 650+ clients supported, one observation comes back without exception: the sites which do not move forward despite a significant content budget almost all have a technical or structural problem not resolved upstream. Sometimes, correcting a single point (cannibalization, for example) is enough to trigger an increase of 20 to 30% in traffic without publishing a single new page.

What are the 4 priority technical audit points?

Point 1 — Crawlability and indexing

Start by checking that Google can access all your important pages. Use Screaming Frog (free version up to 500 URLs) or Sitebulb to crawl your site. Check that robots.txt is not blocking your category or product pages. In Google Search Console, monitor the Coverage report to identify pages that are indexed, excluded, or in error.

On an average e-commerce store with 500 to 5,000 products, it is not uncommon to find 20 to 40% of important pages unindexed — facet pages, product variations, duplicate pagination pages. Every unindexed page is a lost traffic opportunity.

Point 2 — Loading speed

Google has been using Core Web Vitals (LCP, INP, CLS) as a ranking signal since 2021. On mobile, an LCP greater than 2.5 seconds directly penalizes positioning. Test with PageSpeed ​​Insights (free) and GTmetrix. The most common causes in e-commerce: unoptimized images (WebP not used), blocking third-party scripts (chat, tracking), undersized shared server.

Point 3 — Structure of URLs and parameters

E-commerce businesses often generate hundreds of thousands of URLs via filters, sorting and pagination. Without correctly configured canonical tags or noindex directives, you create duplicate content at scale. Verify that each facet page (color, size, brand) points to the corresponding canonical category page.

Point 4 — Structured data (Schema Markup)

Structured data is not optional for e-commerce in 2026. Product schemas (with price, availability, reviews), BreadcrumbList and FAQPage are essential for rich snippets and for visibility in Google AI Overviews. Test your pages using Google’s Structured Data Testing Tool.

Point 5 — Keyword cannibalization

Cannibalization occurs when multiple pages on your site target the same keyword. Google doesn’t know which one to promote and oscillates between the two — result: neither ranks well. Detect it with the command site:yoursite.fr “targeted keyword” in Google, or with Semrush (“Cannibalization” report). On e-commerce, frequent cases: category page AND blog article on the same query, two almost identical categories.

Point 6 — Unexploited keyword opportunities

Google Search Console often reveals dozens of queries where your site is ranked 8 to 20 — too low to generate clicks, but high enough to signal real potential. These queries are the basis of a semantic cocoons strategy: create dedicated pages on these topics to capture existing but unconverted traffic.

Point 7 — Thematic coverage vs. competitors

Analyze the top 3 competitors on your target queries with Semrush or Ahrefs. What keywords are they ranking for that you don’t have? These semantic “gaps” are the priorities of your next content strategy. A gap of 300 keywords often results in a lack of 5 to 15 entire themes to cover — so many cocoons to deploy.

What are the 2 internal mesh audit points?

Point 8 — Orphan pages

An orphan page is a page without an inbound internal link. Google rarely crawls it and gives it little PageRank. On e-commerce, orphan pages are often product sheets for new collections, blog pages not linked to the rest of the site, or landing pages created for campaigns and forgotten. Screaming Frog identifies orphan pages via the « Orphan Pages » report (paid version).

Point 9 — Excessive click depth

If an important product sheet requires more than 3 clicks from the home page, it receives little PageRank and is crawled less frequently. On an e-commerce with a deep hierarchy (Home > Category > Subcategory > Sub-subcategory > Product), level 5 products are structurally disadvantaged. The solution: contextual links from blog articles, links from the homepage to priority subcategories.

Point 10 — Thin content (insufficient content)

Category pages without textual content (only a product grid) and product sheets with descriptions copied from the manufacturer are the two most common forms of thin content in e-commerce. Google considers them of little use. The audit involves identifying all pages with more than 500 GSC impressions with content less than 200 words — these are the enrichment priorities.

Point 11 — Internal duplicate content

Product variations (size S, M, L of the same reference) often generate almost identical pages. Identical descriptions across multiple product sheets create duplicate content at scale. The solution: canonical tags pointing to the main page, unique content on each variation if the pages must remain indexed.

Point 12 — Inbound Link Profile

A healthy backlink profile is characterized by a diversity of referring domains, varied anchors (not 80% exact anchors on the same keyword) and an absence of toxic links. Use Ahrefs or Semrush to analyze your profile. If you find spam or link farm links, submit a disavow file through Google Search Console.

The backlink audit also reveals opportunities: which competitors have links that you don’t have? These domains are your first targets for a link building campaign. Combined with our GEO campaign, a quality link profile amplifies presence in LLMs and AI engines.

Once these 12 points have been audited, you have a precise map of priorities. As a general rule, correcting points 1 to 5 generates quick gains (2 to 4 months). Points 6 to 12 feed into the content and semantic cocoons strategy to be deployed in the following months. Find the details of our approach in our SEO blog.
