What HGM actually did to create movement.

A practical view of the workstreams behind the result, before the long-form story expands on the details.

01

Find the real constraint

We reviewed where large e-commerce growth was stalling across visibility, content depth, technical health, conversion paths, and measurement.

02

Rank the work by impact

The Technical SEO work was ordered around the changes most likely to influence qualified demand, not around a generic checklist.

03

Execute the growth work

Crawl paths, link depth, anchors, category relationships, and priority pages were reviewed before restructuring recommendations were made.

04

Track the movement

32% more organic category clicks, 44% fewer orphaned URLs, and crawl depth reduced for 126 priority ecommerce pages.

The decisions, fixes, and execution behind the result.

Who Was the Client?

A large ecommerce website with many products, categories, subcategories, and supporting content pages.

What Was the Challenge?

As the catalog expanded, internal links became inconsistent. Some high-value categories were too deep, product groups were poorly connected, and supporting content was not passing relevance to commercial pages.

What Was the Strategy?

We audited crawl depth, internal anchors, orphaned pages, category paths, navigation links, and blog-to-category connections. Recommendations were organized by commercial impact.

What Were the Results?

  • Priority categories surfaced more clearly
  • Internal links mapped around revenue pages
  • Crawl paths simplified for important templates
  • Scalable linking rules created for future products

Impact Metrics

  • 32% increase in organic clicks to category pages
  • 44% reduction in orphaned URLs
  • 126 priority pages moved closer to the homepage
  • 18% lift in product-page revenue from organic traffic

Why Did This Work?

Large ecommerce SEO depends on architecture. Internal linking cleanup helped search engines understand which categories mattered and how products related to search demand.

For similar architecture work, see Technical SEO for crawl paths and indexation, or Ecommerce SEO when category, product, and content pages need to support revenue together.

We thought the issue was just traffic. HGM showed us that our product pages were not explaining the offer clearly enough. The changes were practical, the reporting was easy to follow, and the enquiries we got afterwards were a better fit.

Questions this case study can help answer.

What was the main constraint in this Technical SEO case study?

Important product and category pages were buried because internal links had grown messy over time.

What work did HGM focus on first?

Crawl paths, link depth, anchors, category relationships, and priority pages were reviewed before restructuring recommendations were made.

Can this result be guaranteed for another business?

No. This case study shows what changed in one context. Results depend on the starting website, market, competition, tracking, offer quality, implementation speed, and the buyer journey.

Is this case relevant for other e-commerce businesses?

It can be useful as a pattern, but the right plan still depends on the specific market, service mix, proof assets, conversion path, and growth constraint for each business.
