Technical SEO audits for e-commerce stores

Shopify, WooCommerce, BigCommerce, and Magento stores have a similar technical-SEO failure shape: thousands of templated product pages, faceted navigation, and theme updates that silently break structured data. Wrendex audits the catalog daily so you catch regressions the day they ship, not the next quarter.

All 140+ checks run on every audit. Free audit, no credit card.

Issues that frequently surface on e-commerce stores

6 common patterns from real audits.

Out-of-stock products still return 200

Discontinued SKUs stay live as soft-404s instead of returning 410 Gone or redirecting to a category. Search engines keep crawling them and indexing thin pages.

Faceted navigation generates duplicate content

Sort and filter combinations spawn thousands of crawlable URLs that share the same product set. Without a canonical strategy, every page competes with itself.

Review snippets break after a theme update

Theme upgrades on Shopify and WooCommerce frequently strip or break Product and AggregateRating JSON-LD. Rich-result eligibility silently disappears between deploys.

Canonical points at the wrong variant

Color and size variants get a canonical pointing at a parent SKU that is itself out of stock or noindex. The canonical chain leaks crawl signal away from the page that should rank.

Pagination loops with infinite scroll

Infinite-scroll category pages append parameters that are not handled by the canonical, producing redirect chains and deep pagination that bots abandon before reaching the long tail.

Duplicate analytics on PDPs

Layout-level GA tag plus a Tag Manager tag plus a vendor pixel injection produce two or three pageviews per product view. Conversion math gets unreliable.

Wrendex catalog checks that fire on e-commerce stores

9 checks, 4 linked. Linked checks open the full catalog entry: what it is, why it matters, how to fix it. The rest are industry-specific checks fired during the audit; their detail pages arrive in the next catalog refresh.

• 404-on-crawled (detail page coming)
• soft-404 (detail page coming)
• canonical-missing
• canonical-points-to-4xx
• title-duplicate
• redirect-chain
• duplicate-tracker (detail page coming)
• Product JSON-LD broken (detail page coming)
• Out-of-stock returns 200 (detail page coming)

What an audit run on a e-commerce store actually produces

5 steps on the first run.

1. Crawl the live catalog. Wrendex follows internal links, samples templated PDPs and category pages, and records the response code, canonical, and structured data on every URL.
2. Group issues by template. The audit clusters findings by URL pattern (PDP, PLP, brand page, search results) so you triage by template, not by individual URL.
3. Drill into the worst-offending template. Open one product-detail page and Wrendex shows every check that fired on that template family, with the source line where the issue surfaces.
4. Get PR-ready remediation. Each finding ships with concrete fix copy: the exact <link rel="canonical"> value to render, the status code to return, the JSON-LD shape to emit.
5. Re-crawl and verify. After deploy, Wrendex re-runs the affected templates and confirms the fix. Regressions in the same template re-fire in the dashboard on the next daily audit.
