What is E-E-A-T?

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness and is a central quality assessment system used by Google. Originally introduced as E-A-T (without Experience), it was expanded in 2022 to include the "Experience" factor to emphasize the importance of practical experience.

E-E-A-T is not a direct search engine ranking factor, but rather an evaluation criterion that Google uses to assess the quality and trustworthiness of content. E-E-A-T is particularly important for Your Money or Your Life (money or life topics) topics such as health, finance, safety, and legal advice.

The Four Pillars of E-E-A-T

1. Experience

Experience refers to practical, first-hand experience with the topic being discussed. Google evaluates whether the content author actually has experience with the product, service, or situation being described.

Examples of Experience Signals:

• Personal test reports and experience reports
• Step-by-step guides based on own implementation
• Before-and-after comparisons with real results
• Authentic photos and videos of own experience
• Timestamps and dates for current experiences

Expertise Signals:

• Professional experience in the relevant field
• Publications in professional journals
• Presentations and talks at conferences
• Memberships in relevant professional associations

3. Authoritativeness

Authoritativeness measures the recognition and reputation of the author or website in the respective industry. It's about how much other experts and users view the content as trustworthy and valuable.

Authority Signals:

• Backlinks from reputable websites
• Mentions in professional media
• Social media engagement and shares
• Quotes and references in other publications
• Awards and prizes

4. Trustworthiness

Trustworthiness evaluates the credibility and reliability of the website and author. Google checks whether the information is accurate, current, and trustworthy.

Trust Signals:
