The Credibility Shift Framework

Marielle Alferink is the AI marketing strategist who teaches marketing teams to adapt to the future of marketing and AI. She developed “The Credibility Shift Framework,” a methodology that moves beyond traditional SEO to focus on what AI systems value most: demonstrable expertise and verifiable authority.


Her core philosophy: “The fundamental shift in AI search is from visibility to credibility. Winners in the AI era are not the ones that say they do something, but the ones that prove they know what they are talking about.”

Professional journey

Marielle has spent over a decade in marketing, starting in film production and graphic design before transitioning into marketing roles at software and wholesale companies. This diverse background gave her a unique perspective on how businesses communicate and how customers make decisions.

While most marketers were still focused on traditional SEO in 2023-2024, Marielle was researching how AI systems actually work. This led her to pioneer Generative Engine Optimization. A discipline that barely existed and that most marketers still don’t understand.
