About Ben

Achievement is the sum of dreams, courage, competence multiplied by skills. With this mindset, I get up full of energy every morning, after dreaming at night about this fascinating globe we share.

My credo as a marketer is: ‘no words, but data’.
Because if my work starts with an interesting question, it always ends with measurable(!) results:

• I am a full-blooded strategic thinker with over nine years of experience in online marketing, rooted in SEO and SEA, driven by data and conversion (CRO), and enriched by passionately teaching and mentoring talent in higher education at Tio Business School.

• I am strongly analytical and commercially oriented, answering business questions with the right mix of web, campaign, market, and customer data. I communicate clearly: to clients, specialists, and technical stakeholders. I support beliefs with facts, make choices explicit, and translate them into concrete instructions.

• I help (B2C and B2B) organizations sharpen their growth goals, ask the right questions, and translate those goals into a concrete, scalable roadmap that works. I do this by analyzing web, campaign, market, and customer data in conjunction, forming hypotheses, and running experiments that prove opportunities.

• I contribute and advise at C-level, manage teams for results, and build strategic marketing that is technically sound, commercially performing, and future-proof in an era of zero-click, SGE/AI Overviews, and smart automation.

Daily, I work with Google Ads (Search, Performance Max, Display, YouTube); with GA4 and Google Tag Manager for measurement and attribution; with Google Search Console and Ahrefs/Semrush for search data; and with Merchant Center and Channable for feed-driven performance. I use Meta and LinkedIn Ads where they demonstrably contribute to the whole. I use HubSpot to visualize the pipeline and automate repetitive tasks where appropriate.

Experience

  • Key-advice, Marketing Agency
    Senior Marketeer SEO/SEA | Data Analyst CRO
    DIGITAL AND IT
    December 2019 - Today (6 years and 6 months)
    Amsterdam, Netherlands
    Key-advice supports B2B and B2C organizations in defining, implementing, and adjusting digital marketing strategies, with data-driven decision-making as a strong foundation. The scope ranges from SEO and SEA to paid media and PR, CRO, Data Analytics, content, and CRM. Organizational goals are thus demonstrably and consistently achieved with increased visibility, a stronger market position, and demonstrable growth in conversion and revenue. Our consistent credo is: 'No words, but Data'.

    We work with a proven stack, such as: Google Search Console, Google Ads (Search, Performance Max, Display, YT), GA4 & Tag Manager, Merchant Center and Channable, Google Business Profile, Meta- LinkedIn Ads and automation (HubSpot, Mailchimp).

    Artificial Intelligence has become an integral part of our approach in recent years. AI enables us to efficiently process large datasets and generate valuable insights; advanced algorithms recognize patterns and predict customer behavior. This leads to sharper market analyses, smarter segmentation, and more precise targeting. The efficiency and accuracy of our campaigns demonstrably increase, resulting in higher conversion rates and relevant, personalized content. In short: AI enhances every step from analysis to optimization and provides sustainable competitive advantage.

    As the person ultimately responsible, I translate account data into decisions and execution. After a statistically sound baseline measurement and diagnosis, I translate the findings into an implementation plan with clear KPIs, ownership, planning, and budget. We execute the measures end-to-end (autonomously or in co-creation with the client), ensuring adoption and strictly managing KPIs for immediate demonstrable impact. This is achieved through clear communication, smooth collaboration across teams and departments, and the consistent, expert use of our analysis tools. This is how we translate ambition into demonstrable growth.

  • Tio Business School
    Marketing & E-commerce Lecturer (University of Applied Sciences)
    E-COMMERCE
    December 2022 - September 2025 (2 years and 9 months)
    Amsterdam, Netherlands
    At Tio Business School, I am responsible for designing and teaching the Marketing and E-commerce (Advanced) modules, and I also supervise final-year students with their Theses. In this part-time role, I combine my extensive academic knowledge with my own practical experience to inspire students and prepare them for a dynamic and rapidly evolving market.

    My goal is to equip students with the skills and insights needed to succeed in their future careers. In my lectures, I strive to give students a deep understanding of both traditional and digital marketing strategies. I cover various topics ranging from brand management and consumer psychology to SEO/SEA, CRO, and social media.

    Through case studies, interactive workshops, and guest lectures from industry experts, I help students translate theoretical knowledge into practical applications. As a lecturer for the E-commerce modules, I guide students through the complex world of online commerce. I cover advanced topics such as digital strategies, data analysis, customer behavior, and the technologies driving the e-commerce sector.

    My approach is practice-oriented, encouraging students to develop innovative projects that align with the latest industry trends and best practices. As a thesis coach, I guide students through the entire research and writing process: from problem definition and literature review to methodology, data analysis, reporting, and defense.

    As complex marketing and e-commerce issues from graduating students are entrusted to me as a thesis coach, my thesis supervision also aligns with my specialization and practical experience. I ensure academic quality through sharply formulated questions, a solid theoretical framework, a clear conceptual model, and testable hypotheses. I advise on research design, sampling, instruments, and A/B testing.

    JOUW.STUDIO helps organizations from various sectors to elevate their content strategy and execution. This process begins with thorough exploration and measurement: product, proposition, and target audience on one hand; competition, market mechanics, and channels on the other. Based on this, in close collaboration with the client, we formulate clear positioning and a sharp, commercial message, translated into a realistic action plan with clear priorities, measurement points, and responsibilities. The result is communication that reaches the right people, at the right time, with demonstrable impact.

Additionally, I coached freelancers and SME teams through seminars, masterclasses, and individual consultations.
