Meet the Person Behind C-Growth

Marielis Martinez — Founder & Lead Website Optimization Analyst

With close to a decade of experience in digital marketing, Marielis Martinez has spent the majority of her career doing one thing exceptionally well: understanding why website visitors don’t convert and fixing it.

Her expertise sits at the intersection of website optimization, conversion rate optimization (CRO), audience persona development, and funnel analysis. Where most marketers focus on driving traffic, Marielis focuses on what happens after the click, the behaviors, friction points, and missed opportunities that determine whether a visitor becomes a customer or quietly leaves.

Based in Tromsø, Norway, Marielis has worked with tourism businesses and established local organizations in the region, delivering in-depth website audits that identify exactly where digital experiences are falling short and what data-driven changes will move the needle. She is currently expanding her practice into the international market, bringing the same rigorous, analyst-led approach to mid-size companies and marketing teams around the world.

Her work goes beyond standard analytics. Marielis analyzes how your target audience behaves on your site, how search engines and AI tools interpret and represent your content, and how your entire conversion funnel performs from first visit to final action, giving you and your team a complete picture and a clear path forward.

Our Mission

To help businesses stop guessing and start growing, by turning website data into decisions that actually drive revenue.

We believe every business deserves to know what’s really happening on their website: who’s visiting, what they’re looking for, where they’re getting stuck, and what it would take to convert more of them. Our job is to find that out and give you the clarity to act on it.

Who We Work With

C-Growth works with two types of clients:

Marketing teams at mid-size and large companies who are receiving traffic from organic and/or ads but aren’t seeing the conversion results they expect. We plug in as your optimization partner, auditing your site, analyzing your data, identifying your gaps, and giving your team a concrete roadmap for improvement.

Digital and advertising agencies who want to offer their clients more value. If your agency drives traffic but doesn’t offer CRO or website analytics services, we can be your behind-the-scenes partner, delivering the audit and optimization work under your brand or alongside your team.

In both cases, you get a senior analyst dedicated to understanding your specific audience, your funnel, and your goals, not a templated report.

Whether you’re aiming to enhance your user experience, boost your conversion rates, or create an exceptional online presence, we’re dedicated to working alongside you every step of the way.
