Two bodies of work shape the methods. The first is PhDr. Oliver Scharfenberg’s empirical study of employer seals, which analyzed more than 60 seals and included a randomized experiment with 1,093 participants. It is indexed on Google Scholar and ResearchGate and forms the basis of the firm’s advice on employer branding and certification.

The second is The AI Visibility Playbook, which brings together current studies on search and AI answers, such as the Princeton research on Generative Engine Optimization, and turns them into practical frameworks.
