About Southern Ocean Subsea
SoSub is an Australian subsea technology company specialising in advanced ROVs (Remotely Operated Vehicles) and underwater robotics. Founded in Tasmania, the company develops solutions that improve efficiency, safety, and sustainability in aquaculture and marine operations.
Their flagship innovations, including the APAMA ROV and Net Repair System, are designed to reduce downtime, minimise environmental impact, and transform how underwater maintenance is performed.
With strong engineering roots and real-world application, SoSub quickly built credibility within Australia’s aquaculture sector but their expertise extended far beyond local waters.
The Challenge
A global product, but a local digital footprint.
Despite having world-class technology, SoSub faced a common issue for highly specialised regional businesses:
- Limited visibility outside Tasmania
- Strong local reputation, but low national and global discoverability
- A niche industry where buyers are global-but search visibility wasn’t
- Reliance on word-of-mouth and industry networks rather than inbound leads
Even though their technology had clear international relevance (with demand in markets like Norway, Scotland, and Canada ), their digital presence wasn’t positioned to capture that demand.
Solution
Our approach focused on repositioning SoSub from a Tasmanian operator to a global subsea technology leader through:
- Website Positioning & Messaging
- Reframed content to highlight innovation, scale, and global applicability
- Shifted messaging from “local capability” to “Australian-built, globally proven”
- Structured pages to speak directly to international aquaculture and subsea clients
- SEO Built for a Global Industry
- Targeted high-intent keywords around:
- Subsea robotics
- ROV technology
- Aquaculture automation
- Optimised technical SEO to improve crawlability and indexing
- Built content aligned with industry search behaviour and not just brand terms
- Authority & Content Strategy
- Developed content that positioned SoSub as a thought leader, not just a supplier
- Highlighted real-world applications, performance data, and innovation
- Reinforced credibility through industry relevance and use cases
This report compares website performance for SoSub across two distinct periods: the three months before Extreme Marketing engagement began, and the four months of active SEO and digital marketing activity following client sign-up on November 5, 2025.
The results are clear. Within four months of commencing digital marketing activities including blog publishing, social media campaigns, and content strategy , the SoSub website experienced dramatic impact andmeasurable growth across every key traffic metric.
The website went from attracting ~420 visitors per month to over 900 — more than doubling its audience.
Two entirely new traffic channels (Paid Social and Organic Social) were activated from scratch.
Organic search presence was maintained and referral traffic more than doubled (+124%).
Form submissions increased by 33%, indicating higher-quality and more engaged visitors.
The average search position improved from 23 to 10.- a shift of nearly 13 places. In practical terms, SoSub moved from appearing on page two or three of Google search results to appearing on page one.
The SoSub website is now attracting visitors from a significantly wider geographic footprint. The social media and content campaigns have accelerated reach into new international markets.
Canada and the United Kingdom emerged as significant new markets, with Canada growing from near-zero to 463 active users. This geographic diversification reduces reliance on any single market and opens doors to new commercial opportunities for SoSub. This aligns with SoSub’s broader trajectory where their technology is now being deployed internationally, proving demand well beyond Australia.
