Eeat Signals

This walks you through adding Experience, Expertise, Authoritativeness, and Trustworthiness signals to content, which matters especially for YMYL topics like health or finance. It covers author bio structure (credentials, schema, placement), citation strategy, and how to demonstrate first-hand experience through case studies or original research. The skill gives you a concrete assessment of E-E-A-T gaps plus recommendations for bios, citations, and experience signals. Useful when you're writing anything where credibility affects whether people trust the information, or when you need to make AI-assisted content feel less generic by layering in verifiable expertise and real-world proof.
