Custom catalog scope

Ecommerce catalog migration audit

A custom technical SEO audit for large catalogs where product URLs, category routes, filters, canonicals, redirects, sitemap splitting, and post-launch monitoring decide whether rankings survive the migration.

View sample audit

Scope	Best fit	Boundary
Standard audit	Small marketing or content site	Public 490 dollar audit when URL volume and risk are contained.
Urgent recovery	Traffic dropped after launch	Custom diagnostic when rankings, indexed pages, or revenue changed after migration.
Catalog migration	1,000 to 10,000+ product/category URLs	Custom audit for product, category, filter, stock-state, sitemap, and redirect risk.
Code-aware review	Next.js, Payload, route handlers, middleware, CMS models	Custom scope when the cause may live in routing, metadata, canonicals, or sitemap generation.

What gets checked

The public 490 dollar audit is not forced onto catalog sites. Catalog migrations need a wider evidence set because one routing or canonical rule can affect thousands of URLs.

Product URL inventory, old-to-new mapping, and SKU or slug matching confidence.

Category, collection, tag, brand, filter, pagination, and search-result indexability rules.

Redirect chains, 404 product removals, out-of-stock policies, and homepage catch-all detection.

Canonical policy for duplicate products, variants, faceted pages, alternate categories, and retired URLs.

Sitemap splitting, lastmod policy, omitted URLs, noindex leakage, and stale submitted sitemaps.

Structured data parity for Product, Offer, BreadcrumbList, AggregateRating where visible proof supports it.

Internal links from navigation, category grids, product recommendations, breadcrumbs, and blog assets.

GSC/GA4 comparison by product group, category group, country, device, query family, and lead or revenue event.

Deliverables

Catalog risk map

Priority URL groups, failure modes, severity, evidence source, and owner for implementation.

Redirect and canonical queue

Rows for missing redirects, wrong destinations, duplicate routes, canonical conflicts, and recrawl order.

Sitemap and indexability audit

Which catalog URLs belong in XML sitemaps, which should be excluded, and which are missing from discovery.

Developer-ready findings

Implementation notes tied to route handlers, middleware, CMS fields, templates, and deployment behavior.
