Viral Tik-Tok Cellular Health Girls’ Brand Strategy and Conversion Copywriting Project

Sep 12

The Cellular Health Girls came to me after going viral on TikTok with zero conversion strategy—they had visibility but no cohesive brand voice or messaging framework to translate that attention into meaningful engagement.

I developed their entire verbal identity system from the ground up: conducted cultural scans to understand how midlife women actually talk about cellular health, analyzed competitor messaging to find positioning white space, and created a messaging architecture that balanced scientific credibility with the bite-sized, accessible tone their audience craved.

KPCopy wrote everything from developing their website: Home Page, About page and Blogging ensuring every touchpoint maintained consistent voice while adapting for platform and context while maximizing SEO/AEO.

What made this project especially relevant is that I wasn't just writing copy—Using language as a lens to understand identity and decision-making. Diving deep into SEO/AEO keyword research discovering that midlife women search "why am I always tired" over 12,000 times monthly, revealing frustration that clinical language alone couldn't address.

I experimented with AI tools to rapidly test messaging variations while maintaining the human craft that makes wellness content feel authentic rather than algorithmic. The result was a brand voice that helped them cut through the noise in an oversaturated wellness space, positioning them as the go-to resource for women seeking practical cellular health solutions. It was strategy, copywriting, cultural analysis, and AI experimentation all working together—for 28% more engagement.

What felt confusing before now feels sharp, focused, and easy to communicate. She has a real talent for turning ideas into words that connect, and she gave us a framework we can keep using as we grow. Highly recommend working with her if you want messaging that actually moves people to action.” -Risa Lynch

“Working with Karin Priou at KP Copy was a transformative experience for our brand.

Over four months, Karin helped the Cellular Health Girls clarify our message, rebuild SEO-optimized landing pages, and develop a blog that speaks directly to our audience. Thanks to her strategic AEO work, we now rank in the top 4 Google results—each linking to a core part of our business.

Karin’s unique gift is translating brand vision into clear, compelling digital presence. She understood our ideal customer, challenged us to refine our offerings, and kept us focused through three major projects. Her clarity, organization, and deep industry knowledge made all the difference.

If you're looking to elevate your message and connect meaningfully online, Karin is the expert you want in your corner.” -Dawn Jenkins
