Growth Marketing

I help companies grow systematically with an emphasis on sustainable and measurable results. I combine SEO with modern growth marketing approaches, CRO, and strategic use of AI.

Together we will focus on:

  • Creating a scalable, data-driven growth strategy
  • Optimizing the entire customer acquisition process
  • Improving user experience (UX) and conversion rate
  • Reducing customer acquisition cost (CAC)
  • Increasing customer lifetime value (LTV)

As a hands-on consultant, I bring a unique combination of SEO expertise and a growth mindset to projects. Thanks to experience with data analytics and the latest tools, I can create a strategy but also help with its implementation.

"Without question, Jan is the most knowledgeable SEO consultant I have ever worked with in my 15+ year career!

Beyond his expertise, he's just a nice guy always looking out for our company's best interest. I'll randomly get emails from Jan with suggestions for little improvements we can make (which often lead to big impact!). Jan's expertise is one of the prime reasons why organic website traffic to childmind.org has grown 112% in the past 5 years."

Initial SEO Audit

A strategic approach to SEO forms the foundation for sustainable growth. My process begins with:

  • Comprehensive analysis of current performance metrics and processes
  • Gap assessment and completion of essential audits (including targeted keyword research)
  • Full SEO impact analysis and quick-win identification. I focus on key areas including:
    • Keyword strategy and site architecture optimization
    • Landing page content optimization and on-page SEO
    • Technical SEO evaluation
    • Backlink profile analysis
    • Market-specific SEO considerations
    • Strategic recommendations and action item prioritization

The initial audit aims to quickly improve the website's organic search visibility while establishing a solid foundation for long-term SEO success. This strategic assessment serves as a practical roadmap for all subsequent optimization efforts.

An experienced specialist can find the biggest shortcomings on the website in a short time. Thanks to the initial audit, we can quickly get to work and see results sooner.

Long-term processes in SEO and 1:1 mentoring

SEO initiatives typically fail due to two key factors: lack of established long-term processes and insufficient senior expertise.

As your dedicated SEO partner, I focus on continuous process optimization, working collaboratively to implement the most effective SEO strategies for your organization.

You'll gain a committed SEO advocate who not only monitors performance and proactively develops solutions, but also brings the expertise to make informed, strategic decisions.

Through ongoing mentoring, I'll help your team develop their capabilities while providing senior-level guidance. My goal is to help your team achieve and celebrate meaningful SEO success.
