Will North has led marketing and commercial functions at brands including Meshki, PE Nation, AJE and Superdry UK. For the last two and a half years he's been at <a href="https://www.kulanikinis.com/" target="_blank" rel="noopener noreferer">Kulani Kinis</a>, the Australian swimwear brand doing 75-80% of its revenue in the US. He joined Ryan Martin from <a href="https://www.remarkabledigital.com.au/" target="_blank" rel="ugc noopener noreferrer">Remarkable Digital</a> to talk conversion rate optimisation, attribution, TikTok Shop and the marketing shifts defining 2026.The Kulani Kinis story. Founded 11.5 years ago by Sydney couple Danny and Alex as a side hustle, the brand found its footing in the US when Alex transferred to EY in LA. Today the US makes up 75-80% of revenue; Australia is just 7%.CRO is a business metric, not a digital one. Will's Retail Fest keynote ("I Lost the Company $15 Million and Got a Promotion") explored why every untested change to your site is a potential loss. His starting point: survey customers who've purchased and subscribers who haven't, distil 3-4 themes, then run ideas through an effort-versus-upside matrix before testing.Context kills best practice. Adding "some items in your cart may sell out" drove nearly $2M in annualised revenue at a streetwear brand. The same test lost revenue at a women's fashion brand, because scarcity signalling made shoppers worry about wearing the same thing as everyone else. Customer psychology differs by brand.The thank you page question nobody asks. Immediately post-purchase, ask: "Was there anything that almost stopped you from buying?" Customers who've just converted will tell you exactly what's broken.Attribution in 2026. No one does it perfectly. Will's approach is to define the role of each channel across the seasonal cycle and measure a marketing efficiency ratio (spend divided by sales) as a flow, not a fixed weekly target.TikTok Shop. 72% of fashion revenue on the platform flows through affiliate and creator. The new customer rate is 95%. Will visited the US team last month and TikTok Shop is a major focus for Kulani Kinis in FY27.What you say now matters as much as how you look. LLMs are changing discovery. If a brand has no content narrative, it won't show up when someone asks an AI for a recommendation. Will's take: GEO, AIO and SEO are all just SEO.Not all impressions are equal. Kulani Kinis ran direct mail via Post Pilot at a $600 CPM and it outperformed. A postcard on a fridge is a very different impression to a feed scroll-past.In-person events. A $40,000 Maldives brand trip generated the equivalent of $140,000 in media value from creator and customer content.Collaborations. A LinkedIn conversation between brand experience leads led to a Lounge Underwear collab that spiked Kulani Kinis' German sales in July 2024. Go in with clear objectives or don't bother."Conversion is a business metric. It's not an e-com metric.""There is no such thing as best practice with CRO. Every brand's customer psychology is different.""You've got to sell it twice: on site and when they get it, otherwise it's coming back."<ul><li>Kulani Kinis: kulanikinis.com</li><li>Post Pilot: postpilot.com</li><li>Lounge Underwear: loungeunderwear.com</li><li>Pura Vida Bracelets: puravidabracelets.com</li><li>Retail Fest</li></ul> About Will North:Head of Commercial & Performance at Kulani Kinis.
