01 — Overview

A specialist brand fighting for visibility in a highly technical commercial category.

WebRefresh partnered with STULZ Oceania, a specialist in mission-critical cooling and essential infrastructure solutions, to overcome complex technical barriers and implement a high-value, multi-pillar SEO strategy.

The campaign goal: exponentially increase commercial visibility, establish industry authority, and drive qualified lead generation across the Australian and New Zealand markets — in a category where the buying audience is small, technical, and high-value.

02 — The Challenge

Foundational technical limitations were holding back a brand with genuine industry expertise.

  • /01

    Technical roadblocks

    The existing website architecture severely hindered local market SEO efforts and accurate conversion tracking. Schema markup and analytics settings were misaligned to the Oceania market, suppressing local search visibility.

  • /02

    Invisible commercial keywords

    High-value, product-focused commercial keywords like "data center containment" and "chiller unit" were ranking outside the top 100 — effectively making STULZ invisible to customers actively searching for their core solutions.

  • /03

    A need for category authority

    STULZ required a comprehensive content strategy to reinforce its position as an industry leader and capture search traffic for high-value services and future-focused solutions, including UPS systems and Liquid Cooling.

03 — The Approach

A two-pronged strategy: fix the foundations, then build the authority.

WebRefresh executed a strategic, dual-track approach — correcting foundational site issues while implementing a robust content roadmap focused on commercial intent and thought leadership.

Pillar 01

Foundational & UX Improvements

A thorough technical audit and remediation programme to ensure the site was compliant, discoverable and converting traffic efficiently.

  • Local search complianceAligned schema markup and technical settings with the Oceania region to immediately improve local search visibility.
  • Optimised user experienceReworked the homepage with a new above-the-fold CTA and clearer pathways to high-intent service pages.
  • Enhanced discoveryRestructured product category content to improve keyword relevance for both search engines and AI tools.
Pillar 02

Strategic Content & Authority Building

A comprehensive content roadmap — including the 2026 Solutions Strategy — designed to capture immediate commercial demand and long-horizon industry leadership.

  • High-intent service pagesLaunched dedicated pages for Maintenance, Repairs, Audits and Emergency Support to capture existing high-intent search traffic.
  • Evergreen authority contentFoundational resources covering Air Flow Management, Free Cooling and UPS Efficiency to build topical authority across critical infrastructure.
  • Future solutions focusBuilt early authority for long-horizon strategic bets including Liquid Cooling and AI Server Cooling, alongside high-value UPS topics.
04 — The Results

Measurable growth across visibility, traffic and qualified lead volume.

The strategy delivered substantial, compounding growth — not just in rankings, but in the metrics that translate to revenue: non-branded clicks, contact events, and qualified leads.
