Grey Haze: Optimising E-Commerce Infrastructure and SEO to Drive a 62% Conversion Surge

Executive Summary

Grey Haze, a prominent Birmingham-based retailer and online store, possessed a strong market reputation but was held back by a fragmented digital infrastructure and high operational overhead. Working directly with the founders to remove reliance on high-cost external partners, I architected a technical roadmap to strip back technical debt, fixing deep-seated technical SEO issues and hard-coding legacy scripts to transform the site into a high-performance sales engine. This resulted in a 62% increase in conversion rates and a £4k+ monthly reduction in operational costs.

Phase 1: Operational Restructuring & Cost Efficiency

The Problem: The business was heavily dependent on an external agency for maintenance and growth, leading to high monthly retainers and slow execution times.
The Solution:

  • Strategic In-Sourcing: I directed the transition of technical delivery from an external agency to an in-house model, bringing strategic oversight directly under my remit.

  • Workflow Implementation: Developed internal website guidelines to ensure SEO and merchandising consistency across the team.

    Impact: Saved the company £48k+ annually in agency fees while significantly increasing the speed of site deployments.


Performance Engineering: Hard-coded delivery and finance widgets to strip technical debt and improve LCP speeds.

Phase 2: Technical SEO & Search Stabilisation

The Problem: Advertising restrictions in the niche meant organic search was the primary revenue driver, yet rankings were declining due to poor header hierarchy, toxic backlinks, and missing keyword opportunities.
The Solution:

  • Technical Audit: Fixed poorly structured header hierarchies and disavowed toxic backlinks to stabilise site authority.

  • Keyword Expansion: Identified high-volume missing opportunities in the "Disposables" category, creating a new collection with internal linking and schema-marked FAQ sections.

  • Local Dominance: Developed optimised location pages with maps and unique content to drive a 42% increase in local organic traffic.

    Impact: Expanded search visibility to rank for 300+ commercial keywords.


Organic Scaling: Stabilised site authority and technical health to drive a consistent 20%+ increase in daily organic traffic.


Search Visibility: Implemented schema-marked FAQs to capture rich snippets and dominate commercial search results.


Local Market Dominance: Engineered location-specific pages to rank for high-intent "near me" search terms and drive foot traffic.

Phase 3: Performance Engineering & UX/UI

The Problem: Average site speeds and a high volume of legacy plugins/scripts were causing friction in the buyer's journey, leading to "leaky" conversion funnels.
The Solution:

  • Performance Leadership: Managed the development team to hard-code essential logic directly into the theme, reducing JavaScript load and significantly improving LCP (Largest Contentful Paint) by 40%.

  • Navigation UX: Implemented internal collection tiles and multi-buy offer logic to streamline navigation and incentivise higher Average Order Value (AOV).

  • Logistics Optimisation: Advised on the integration of Royal Mail and DHL to improve delivery reliability and customer trust.

    Impact: Drove a 62% increase in the online store conversion rate.


Campaign Performance: Reached a 6.56% conversion rate during peak seasonal promotions, representing a 155% improvement over previous high-traffic events.


Navigation Architecture: Deployed visual collection tiles to streamline user flow and reinforce site-wide internal linking.


Commercial Logic: Developed incentivised multi-buy logic to maximise Average Order Value (AOV) and overall profit margins.

Final Outcomes

The project successfully transitioned Grey Haze from a tech-heavy, agency-dependent model to an agile, high-performance e-commerce brand.

  • 62% Conversion Rate Increase
  • £48k+ Annual Operational Savings
  • 42% Surge in Local Organic Traffic
  • 300+ Commercial Keywords Ranked

Growth Logic

"In highly regulated niches, growth isn't about outspending the competition; it's about out-optimising them. My focus at Grey Haze was on removing the 'agency tax' and architecting a scalable roadmap that turned technical performance into a measurable revenue driver."
