Aligning content with E-E-A-T on-page signals

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trust. On-page signals are your most direct opportunities to communicate these qualities.

Experience and expertise: demonstrate your depth of knowledge through well-researched content, practical examples, and firsthand insights. Link to case studies and credible sources to reinforce authority.
Authoritativeness: showcase qualified authors with clear credentials and relevant publications. Where possible, include author bios that reflect real-world expertise.
Trust: build trust with transparent editorial policies, precise dates for data and content updates, and citations to credible sources. Presenting a robust references section and a clear corrections policy is valuable.

To operationalize these signals on-page, you can:

Add comprehensive author bios and links to relevant credentials.
Include citations to primary sources and peer-reviewed data.
Publish editorial standards and a robust fact-checking process.
