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 hourly so you catch regressions in the deploy window, not the next quarter.

I.01
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.
I.02
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.
I.03
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.
I.04
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.
I.05
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.
I.06
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.

- 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.
- 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.
- 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.
- 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.
- 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 within an hour.
