YELUX / HairSupplierCN/ Case Study

What Crobstacle Found at the Start

When Crobstacle began working on YELUX's organic search presence, the website presented challenges across several areas of SEO. One of the most significant issues emerged inside Google Search Console.

Google was discovering thousands of URLs that were not part of the website's intended SEO or content architecture. At one stage, Search Console reported more than 29.2K URLs as not indexed while only 23 pages were indexed. These URLs included unusual paths, parameter-based URLs and pages that were not part of YELUX's intended sitemap structure, creating substantial crawl noise around the domain.

A Multi-Layered SEO Approach

Crobstacle developed a four-pillar SEO strategy that addressed technical health, on-page relevance, content authority, and external signals in parallel — rather than treating them as sequential or independent activities.

Pillar

Focus

Objective

Technical SEO

Indexing, crawl behaviour, server and WordPress issues

Establish a clean technical foundation so Google can efficiently crawl and index legitimate pages

PHASE 1 — DISCOVERING THE INDEXING PROBLEM

29.2K+ Unwanted URLs in Google's Crawl Queue

During routine Search Console monitoring, Crobstacle identified abnormal URL discovery behaviour. The volume and structure of these URLs required deeper investigation beyond standard on-page SEO.

The team reviewed the website's sitemap, robots directives, URL patterns, website structure and crawl behaviour. The analysis indicated that the intended sitemap and normal SEO activities were not responsible for the thousands of unwanted URLs — pointing toward technical and server-side behaviour rather than a conventional content issue.

Crobstacle documented the problematic URL patterns and provided technical guidance so that the relevant development and hosting-level causes could be addressed.

At the start of the engagement, Google Search Console showed 29.2K+ URLs as not indexed — with only 23 legitimate pages indexed. This level of crawl noise was suppressing the domain's search authority.

PHASE 2 — CRAWL AND INDEX CLEANUP

Reducing Non-Indexed URLs from 29.2K+ to ~1.13K

Once the URL patterns had been identified, the focus shifted toward reducing unnecessary crawl activity and helping Google prioritise legitimate website pages.

Crobstacle worked on sitemap validation, crawl monitoring, index cleanup, reindexing of important pages and coordination around problematic URL handling. Search Console was continuously monitored as Google revisited the website.

The objective was not to force every discovered URL into Google's index. The objective was to create a cleaner search footprint in which Google could focus more effectively on YELUX's legitimate commercial and informational pages.

PHASE 3 — RESOLVING A POST-MIGRATION TECHNICAL ISSUE

WordPress Caching Conflict Causing Homepage Issues

SEO campaigns do not always progress in a straight line. During the project, a technical issue emerged following YELUX's previous hosting migration. The website experienced homepage rendering and WordPress backend accessibility problems.

Investigation and coordination with the technical team identified a conflict involving the Redis Object Cache configuration and the object-cache.php WordPress drop-in. The website was attempting to use Redis even though the caching environment was not correctly configured on the current server.

Crobstacle worked alongside the technical teams to identify the SEO impact and support resolution of the issue. Once the conflicting cache implementation was disabled, website functionality was restored. The homepage was subsequently reviewed and restructured to ensure important SEO elements remained intact.

Technical SEO often requires understanding where search problems intersect with hosting, WordPress, caching and development — not just keyword and content adjustments.

PHASE 4 — ON-PAGE SEO OPTIMISATION

On-Page Score: 72% to 86%

With the technical foundation becoming more stable, Crobstacle focused on improving page-level search relevance across YELUX's priority pages. Optimisation work covered all key on-page elements.

Optimisation work included:

—  Meta title and description improvements across priority pages

—  Heading hierarchy refinement and keyword placement

—  Image alt-text optimisation and image compression

—  Internal linking improvements

—  Content structure enhancement and commercial search-intent alignment

KEYWORD AND CONTENT STRATEGY

Building a B2B Keyword and Content Architecture

YELUX operates in a competitive industry where broad product terms overlap heavily with commercial and B2B searches. Crobstacle mapped keywords according to intent and page relevance, ensuring each priority page had a clear search purpose without competing with other URLs.

Rather than viewing keyword research, on-page SEO and backlink building as separate activities, the strategy connected all three — allowing each important landing page to develop a clearer search purpose and build topical authority over time.

OFF-PAGE SEO — AUTHORITY BUILDING

Structured Backlink Campaign for B2B Visibility

Technical and on-page SEO created the foundation, but competitive international search visibility also required external authority. Crobstacle continued a structured backlink campaign targeting relevant pages and keyword themes.

—  Relevant backlink acquisition targeting priority landing pages

—  Anchor text diversification to build a natural off-page footprint

—  Commercial keyword support through editorial and niche placements

—  Homepage and priority-page authority development

Rather than repeatedly using identical keyword anchors, the backlink profile was developed with greater variation — supporting a more natural and sustainable off-page footprint.
