Understanding E-E-A-T

E-E-A-T refers to Experience, Expertise, Authoritativeness, and Trustworthiness. Google updated its guidelines in December 2022 for search ranking systems and included an extra E. Previously, these guidelines had the acronym E-A-T, meaning Expertise, Authoritativeness, and Trustworthiness. The extra “E” is for Experience.
- Experience – Google now looks for content that shows experience related to the topic. This means that if the user searches for information on paragliding, Google’s search engine results page will rank the pages carrying paragliding information higher.
- Expertise – Google also looks for credibility. It will give higher ranks to content that has been written by someone who has expertise on paragliding and push down copy by a writer with no knowledge on the subject. Expertise refers to a detailed and accurate review.
- Authoritativeness – This refers to the overall reputation in the industry, particularly among those who are experts in the niche. People who depend on you for information, which makes your content authoritative.
- Trustworthiness – This refers to the trustworthiness of your blog or website. It isn’t just about the content and may also include how secure your domain is, what it is doing to protect user information, and the number of positive reviews.

What triggers it: Google sees patterns that only come from real experience. Not “plant tomatoes 18 inches apart” but “I planted my Cherokee Purples 12 inches apart in 2022 and lost 80% to fungal disease. Here’s the photo from July 15.”
Content that works:
• “My 2023 Garden: Complete Harvest Data” – actual numbers, weights, dates
• “Why I Stopped Using Miracle-Gro: 3-Year Test Results” – personal testing
• Before/after photos with dates: “March 1 vs September 1”

Google recognizes: Specific dates, first-person narrative, unique failure stories, progression photos, detailed observations only someone who did it would know.

Google recognizes: Scientific terminology used correctly, cause-and-effect understanding, problem-solving depth, connections between concepts others miss.
3. AUTHORITATIVENESS – Becoming The Source Others Quote
What triggers it: Other sites linking to you as reference. Not self-proclaimed expertise but earned recognition. Your tomato disease guide becomes THE guide others point to.

Content that works:
• About page with real photo: “I’m Sarah, gardening in Ohio since 2008”
• Affiliate disclosure upfront: “I earn from these links, here’s what I actually use”
• Corrections: “Update 2024: I was wrong about neem oil, here’s what works”
• Responding to every comment within 48 hours, even criticism
Google recognizes: Author bio consistency, update timestamps, disclosure presence, engagement metrics, return visitors, low bounce rate on important pages.
How They Connect & Compound
Experience leads to → Expertise (doing teaches you the science)
Expertise builds → Authority (knowledge gets you recognized)
Authority requires → Trust (recognition means nothing without credibility)
Trust amplifies → Experience (people believe your stories when they trust you)
