A developer at heart—30 years of programming experience

Before I became an SEO specialist, I was a developer—and I still am. With over 30 years of hands-on programming experience, I bridge the gap between marketing and technology.

From building custom plugins and APIs to debugging complex site issues, my technical foundation allows me to solve problems most SEOs wouldn’t even spot. Whether it’s PHP, JavaScript, MySQL, or automating workflows with n8n, I don’t just understand the tools—I build them.

This unique blend of strategy and code is what gives my clients a serious edge in search.

Turning search visibility into business growth

My passion isn’t just ranking websites—it’s transforming businesses. As an SEO specialist with over 15 years in the trenches, I’ve learned that success isn’t measured in traffic spikes but in qualified leads that actually grow your bottom line.

I still remember my first client back in 2010—a small bicycle shop struggling to compete with larger retailers. Six months after implementing my SEO strategy, they were turning away customers because they couldn’t keep up with demand. That’s the kind of transformation I live for.

I help businesses increase visibility, attract the right customers, and create sustainable growth through data-driven strategies that adapt to Google’s ever-changing landscape. Think of me as the translator between your business goals and Google’s algorithms—I speak both languages fluently.

Industry expertise that makes a difference

Over the years, I’ve developed specialized knowledge in several industries, allowing me to understand the unique challenges and opportunities each presents:

Coaching and Personal Development – Where connection and credibility are everything
Fitness and Training – Highly competitive but with tremendous local SEO potential
E-commerce and Webshops – Where technical excellence meets conversion optimization
Therapy and Mental Health – Requiring sensitivity and trust signals
Hobby, Crafts, and DIY – Content-rich with passionate, research-heavy audiences
Housing, Construction, and Interior Design – Where visual search and local intent dominate
Health and Wellness – Navigating the complexities of YMYL (Your Money, Your Life) content

This industry-specific knowledge means I don’t waste time figuring out what works—I already know the landscape and can hit the ground running.

Enterprise experience meets small business focus

I’m a Microsoft Certified Professional and Scrum Master PSM I certified with a programming background dating back to 1998. This technical foundation gives me an edge when diagnosing complex SEO issues that others might miss.

My career has taken me through the digital departments of Denmark’s most demanding organizations:

Microsoft – Where I learned enterprise-level technical SEO
Danske Bank – Mastering compliance-heavy content optimization
Nordea – Developing international SEO strategies
Novo – Balancing corporate guidelines with search visibility
DSB – Creating location-based search strategies
SaxoBank – Optimizing for highly competitive financial terms

But here’s the thing—I’ve taken these enterprise-level insights and adapted them for businesses of all sizes. The same principles that drive traffic to multinational corporations can be tailored to help your business thrive, whether you’re a solo consultant or a growing mid-sized company.

My approach: The Convergent SEO Framework

I don’t believe in cookie-cutter SEO. Every business has unique goals, audiences, and challenges. That’s why I developed the Convergent SEO Framework—a holistic approach that aligns technical excellence, content resonance, authority building, and user experience into a unified strategy.

Here’s how it works:

1. Thorough SEO Analysis

I start by diving deep into your website’s current performance, examining:

Technical infrastructure and potential roadblocks
Content quality and keyword targeting
Backlink profile and authority signals
User experience metrics and conversion paths
Competitive landscape and opportunity gaps

This isn’t just a checklist—it’s a comprehensive diagnosis that reveals how these elements interact and where the biggest opportunities lie.

2. Customized SEO Strategy

Based on this analysis, I develop a tailored strategy that:

Prioritizes quick wins alongside long-term gains
Aligns SEO efforts with your specific business goals
Accounts for your resources and implementation capacity
Creates a clear roadmap with measurable milestones

No generic recommendations here—every strategy is built specifically for your business situation.

3. Strategic Implementation

Implementation focuses on four key areas:

Technical Foundation – Ensuring Google can efficiently crawl, index, and understand your site
Content Optimization – Creating and refining content that satisfies both user intent and search algorithms
Authority Building – Developing quality backlinks and brand signals that boost your site’s credibility
User Experience Enhancement – Improving how visitors interact with your site to boost engagement and conversions

4. Continuous optimization

SEO isn’t a one-time project—it’s an ongoing process of:

Monitoring performance against KPIs
Adapting to algorithm updates and market changes
Testing new approaches and doubling down on what works
Expanding into new keyword territories as you grow

What this means for your business

Working with me translates to tangible benefits:

Faster, More User-Friendly Website – I’ll optimize your site’s performance across all devices, reducing bounce rates and improving engagement. I once helped a client cut their load time from 8.2 seconds to 1.4 seconds, increasing their conversion rate by 37%.
Content That Connects and Converts – Your pages will speak directly to your ideal customers’ needs while signaling relevance to Google. One client saw their organic lead quality improve so dramatically that they were able to raise prices by 15%.
Stronger Digital Authority – I’ll help establish your site as a trusted resource in your industry through strategic relationship building. A recent client went from zero industry mentions to being quoted in three major publications within six months.
Data-Driven Decisions – No more guesswork or vanity metrics—every recommendation I make is backed by solid data and tied to business outcomes.

Why SEO matters more than ever in 2025

The digital landscape has transformed dramatically, but SEO remains one of the most cost-effective marketing channels available. Here’s why:

Changing Search Behavior – Today’s consumers research extensively before making decisions, with 81% starting their journey on a search engine
Diminishing Organic Visibility – As paid results and featured snippets take up more SERP real estate, ranking well organically has become both harder and more valuable
Rising Ad Costs – PPC costs continue to climb, making the long-term value of SEO even more attractive
Trust Signals – Organic results carry more credibility with many consumers than advertisements

The businesses that thrive in 2025 and beyond will be those with a strong organic search presence that complements their other marketing channels.

SEO for businesses of all sizes

My approach adapts to your specific business context:

For small to medium businesses

I focus on high-impact strategies that work within your resources:

Localized SEO to dominate your geographical market
Content that targets high-intent keywords with less competition
Strategic link building that maximizes authority gains
User experience optimizations that improve conversion rates

For Larger organizations

I address the complexities that come with scale:

Crawl budget optimization to ensure Google indexes your most important pages
Structured data implementation for enhanced SERP features
Faceted navigation solutions that prevent duplicate content issues
International SEO strategies for multi-market businesses

Realistic timelines for SEO success

I believe in setting honest expectations. While some SEO agencies promise overnight results (a red flag!), here’s what you can realistically expect:

1-3 months: Technical improvements lead to better crawling and indexing. Quick wins become visible as we fix critical issues.
3-6 months: Content optimizations begin driving improved rankings and traffic increases. You’ll start seeing movement for your target keywords.
6-12 months: Authority building pays off with stronger rankings across a wider keyword set. Organic traffic becomes a reliable channel for new business.

One of my e-commerce clients saw a 43% increase in organic traffic within four months, but their revenue from organic search took seven months to double. The best results come to those who commit to the process.

Why choose me as your SEO partner?

Proven Track Record – I’ve helped businesses across multiple industries achieve sustainable growth through SEO
Technical Expertise – My programming background means I understand the technical aspects that many SEO consultants miss
Business Focus – I measure success in revenue and leads, not just rankings and traffic
Transparent Communication – You’ll always know exactly what I’m doing and why it matters
