The Challenge

Coltraco Ultrasonics, a recognised global leader in ultrasonic technology, provides innovative tools such as ultrasonic flow meters, air tightness testing equipment, and hatch cover testing solutions. While their reputation was solid, their online presence wasn’t reaching its full potential. They needed to improve their visibility in search engines, connect with the right decision-makers, and turn that attention into valuable inquiries.

The goal was simple: drive substantial growth in RFQs (requests for quotes) and dominate search results for their core product terms. The outcome? A game-changing 424% increase in RFQs year-on-year and a major boost in online visibility for their flagship products.

 

Coltraco faced familiar hurdles in the competitive B2B space:

1. Low Keyword Visibility: High-value terms like “ultrasonic flow meter,” “air tightness test,” and “hatch cover testing” weren’t ranking well, limiting their ability to attract relevant, high-intent traffic.

2. Outdated Content Strategy: Existing content didn’t align with user intent or optimise for competitive search terms.

3. Underperforming Organic Traffic: The non-branded traffic they were receiving wasn’t translating into inquiries, missing opportunities to engage motivated buyers.

4. Tough Competition: To stand out, competing with global heavyweights in niche B2B industries required a refined and smarter SEO strategy.

The Strategy

1. Strategic Keyword SEO

We carried out a deep keyword analysis across Coltraco’s key product lines to target users actively looking for solutions:

  • Ultrasonic Flow Meter: Focused on high-commercial intent terms to reach businesses searching for flow measurement tools.
  • Air Tightness Test: Targeted informational and transactional queries to ensure visibility across all stages of the buyer’s journey.
  • Hatch Cover Testing: Optimised content to dominate the maritime safety niche, connecting with professionals in this specialised sector.

2. Optimised, Value-Driven Content

  • Created detailed, technically informative product and category pages highlighting use cases, benefits, and clear CTAs.
  • Developed content that answered high-traffic search questions, winning featured snippets for queries like:
  • “What is an ultrasonic flow meter, and how does it work?”
  • “Why is hatch cover testing critical for maritime safety?”

3. Technical SEO Upgrades

  • Enhanced page speed and internal linking structure and implemented schema markup to improve site crawlability and user experience.
  • Ensured all pages adhered to Google’s E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) standards to boost credibility and search rankings.

4. Optimising for Conversions (CRO)

  • Improved CTAs to make the RFQ submission process smooth and accessible.
  • Streamlined the navigation and inquiry forms to remove friction points and encourage action.
