A B2B manufacturing company came to us with a product catalog spanning hundreds of parts and components, convinced their site simply wasn't big enough to compete. The real issue was that a large chunk of their catalog wasn't actually reachable by search engines at all.
The Situation
Their product pages were technically live and technically indexed in some cases, but many had no internal links pointing to them from anywhere else on the site. They existed only if you knew the exact URL or found them through an internal search bar that Googlebot doesn't use the way a human visitor does.
What We Found
A full crawl using the same methodology in our SEO audit checklist turned up over 200 orphan pages, meaning pages with zero internal links pointing to them. Some had been live for years, quietly invisible to both search engines and most human visitors browsing normally through categories.
What We Did
We rebuilt category and subcategory navigation to ensure every product page was linked from at least one relevant category, added a related-products section cross-linking similar components to each other, and built out a proper XML sitemap covering the full catalog rather than just the pages someone had remembered to link manually.
The Result
Within two months, previously orphaned product pages began appearing in search results for specific part numbers and technical specifications, terms with low competition but genuine buyer intent, and organic traffic from long-tail product searches increased meaningfully as a result.
The Takeaway
Large catalogs are especially prone to orphan pages because nobody manually checks every single product's internal linking as the catalog grows. Building internal linking into your on-page SEO checklist for every new product, not just new blog posts, closes a gap most B2B sites don't even know they have.
