JMarketing Agency Reviews & Testimonials
Katie Irving Operations Manager at Advanced Business Abilities
5.0★
Web Design Review from Katie Irving
JMarketing have been an important part of our growth journey for many years. As a business coaching and executive coaching organisation, we were looking for more than marketing execution. We were looking for a partner who could help us understand how prospects engage, what captures attention and how trust is built throughout the buying process. Over the years they have helped us develop websites, training platforms and strategic marketing initiatives that have supported substantial business growth. One of the most valuable aspects of the relationship has been their willingness to continually contribute ideas. They don't simply complete projects and move on. They actively look for opportunities to help us grow further. Their understanding of psychology and human decision-making sits underneath everything they do. More recently, they've helped ensure we remain visible within emerging AI-driven recommendation environments, helping us stay ahead of where marketing is heading. Most importantly, they genuinely care. That is increasingly rare and one of the reasons we've continued working together for so long.

Digital Marketing Review from Mike Irving
JMarketing supported us with a full website redesign, landing pages and ongoing digital marketing for our executive coaching business. Our service is tailored and complex, which creates friction in the buying decision. Previous agencies struggled to articulate what makes us different. JMarketing approached it through the lens of psychology and complex B2B decision-making. They built clear pathways through the website, clarified our positioning and helped us create high-converting landing pages that genuinely reflect how we work. The result feels like having a strong salesperson built into our digital presence. Over the years we've worked together, we've experienced steady growth. Were attracting larger organisations, improving enquiry quality and spending less on advertising than before. Their work has also influenced how I personally present and sell our services. They are proactive, commercially minded and willing to have robust conversations to get things right. If you want strategic input rather than just campaign management, they're an excellent partner.

Web Development Review from David Ashdown
JMarketing partnered with VUKA Group to consolidate multiple exhibition websites into a single unified platform while simultaneously overhauling our messaging and strategic positioning.This was a substantial undertaking. Merging numerous domains required careful SEO planning, technical execution and brand clarity. The outcome has been exceptional.Organic traffic across our brands increased from approximately 1,200 to over 12,000 monthly visits, reflecting an 891% uplift . Our central domain now serves as a powerful authority hub within our industry.Equally important was the messaging transformation. Josh worked closely with us to redesign how we articulate our value to both exhibitors and attendees. We developed an influence cycle that now underpins our broader sales strategy.JMarketing combines strategic thinking, technical capability and commercial focus in a way that is rare among agencies.
