What Is E-E-A-T?

E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is Google’s framework for evaluating content quality, used by human Search Quality Raters to assess web pages. While not a direct ranking factor, E-E-A-T signals help Google understand which content deserves visibility for queries where accuracy matters most.

Understanding E-E-A-T helps content marketing teams create material that both search engines and AI systems recognize as trustworthy and worth surfacing to users.

E-E-A-T Explained

E-E-A-T appears 186 times in Google’s 176-page Search Quality Rater Guidelines. Each letter represents a distinct quality signal:

• Experience evaluates whether content creators have first-hand involvement with the topic. Product reviews from someone who actually used the product carry more weight than theoretical assessments.
• Expertise measures the creator’s knowledge or skills. A certified financial planner writing about retirement strategies demonstrates expertise differently than a hobbyist blogger.
• Authoritativeness considers whether the creator and website are recognized sources for the topic. Industry recognition, citations from peers, and an established reputation all contribute.
• Trustworthiness is what Google calls “the most important member of the E-E-A-T family.” Google’s guidelines state that “untrustworthy pages have low E-E-A-T, no matter how Experienced, Expert, or Authoritative they may seem.”

Why E-E-A-T Matters

E-E-A-T carries extra weight for YMYL (Your Money or Your Life) topics—content affecting health, finances, safety, or well-being. Medical information, financial advice, and legal guidance face stricter quality evaluation.

Google’s 16,000 human Quality Raters use E-E-A-T criteria to provide feedback on search results. This feedback helps Google refine algorithms, similar to how restaurant feedback cards guide service improvements.

For marketing teams, strong E-E-A-T signals improve content performance in both traditional search and AI-powered platforms. LLMs like ChatGPT and Perplexity prioritize trustworthy, authoritative sources when generating answers.

How to Demonstrate E-E-A-T

Building E-E-A-T requires showcasing credentials, experience, and trustworthiness through content structure and author presentation.

Include author bios with relevant qualifications. Add expert quotes with proper attribution. Cite primary sources and link to authoritative references. Structure content so AI systems can identify and extract trustworthy information.
