Who this ecommerce SEO audit is for

  • Stores with large catalogues and faceted category navigation
  • Teams seeing index bloat from filters, sorts, or search-result URLs
  • Brands with variant PDPs competing against each other in the SERP
  • Platform migrations or redesigns where category and PDP templates change

Who this is not for

  • Lead-gen sites without product or category templates
  • Stores seeking only paid-media or email merchandising help
  • Teams that want an open retainer instead of a finite audit

Facets: useful filters without index chaos

Facets help shoppers and can create valuable landing pages when a filter combination matches real demand. Most combinations do not. We map which facet dimensions should be indexable, which should be canonicalized or noindexed, and which should be blocked from crawl entirely. We also catch self-referencing canonical mistakes that let filter URLs stay indexed. Index waste themes are covered in index bloat: find it and what it costs.

Facet and parameter handling patterns we evaluate
URL classTypical intentPreferred control
Core categoryHead demand, browse entryIndex; strong internal links
High-demand facet comboReal search demand (e.g. size+color)Index selectively; unique copy
Sort / view / session paramsUI state onlyNoindex or canonical to clean URL
Multi-facet explosionsNear-zero demandBlock crawl; do not sitemap

# Do not blanket-Disallow all query strings if valuable facets need crawl.

PDPs and variants

Product detail pages need a clear indexation story for variants (color, size, bundles). We check whether variants collapse to a parent, whether unique content exists beyond manufacturer boilerplate, and whether out-of-stock handling soft-404s or preserves equity correctly. Structured data review covers Product requirements that affect rich results eligibility without turning the audit into a schema vanity project.

  • Variant canonical strategy versus separate indexable PDPs
  • Thin PDPs: sparse unique copy, duplicated manufacturer text
  • Internal linking from categories, merchandising modules, and related products
  • Out-of-stock and discontinued URL behavior
  • Image and LCP patterns on mobile PDP templates

Index control for large catalogues

We reconcile sitemaps, crawl discoveries, and Search Console coverage. The goal is a catalogue Google can understand: money categories and PDPs in, utility noise out. When large crawled currently not indexed buckets appear on product templates, we look for quality, duplication, and discovery issues rather than submitting the same sitemap repeatedly. See crawled currently not indexed diagnosis and technical SEO audit checks that matter.

Category architecture and internal discovery

Categories are often the real money pages in ecommerce search. We review depth, pagination, and whether merchandising modules create crawl traps or orphan PDPs. We also check that seasonal or campaign landing pages do not steal canonical signals from evergreen categories without a plan. Pagination and infinite scroll patterns get explicit recommendations so page 2+ of a category does not become an accidental index swamp.

Process

  1. Scope platforms, locales, and sample categories that represent the catalogue
  2. Crawl with ecommerce parameter awareness; pull Search Console and analytics
  3. Audit facet rules, category templates, and PDP/variant behavior
  4. Score findings by revenue exposure and engineering effort
  5. Deliver backlog plus walkthrough for SEO, platform, and merchandising owners

We score with impact versus effort so a cosmetic schema tweak does not outrank a facet ruleset that indexes tens of thousands of junk URLs. Method notes are in impact vs effort scoring for SEO fixes.

Optional implementation after the audit

Rule changes in the platform, template copy, and redirect cleanup can be handled by your team. We can optionally review PRs, re-crawl after facet rule changes, or re-check coverage. That support is scoped after the ecommerce SEO audit, not sold as a vague retainer. For the difference between a finite diagnosis and continuous SEO, read SEO audit or ongoing SEO.
