E-E-A-T SEO Optimization Guide

Build unshakeable authority signals for AI and Google search by Iris (@gingiris) — AFFiNE former COO, 30+ PH #1 launches

TL;DR

• E-E-A-T = Experience + Expertise + Authoritativeness + Trustworthiness
• AI engines (ChatGPT, Perplexity) use E-E-A-T to decide what to cite
• Named authors with credentials are the #1 E-E-A-T signal
• Specific, verifiable claims beat vague statements
• External citations from authoritative sources = your authority
• First-hand experience content gets cited 3x more than generic content

The E-E-A-T Framework

E — Experience

Did the author actually do this?

Signals:

• First-person narrative: "When I launched X..."
• Specific dates and places: "August 2022, in Berlin..."
• Actionable lessons from doing: "I tried X. Here's what happened."
• Screenshots, photos, data from your own work

Content style:

We ran this campaign in Q3 2025 with a $5,000 budget.
Our conversion rate dropped from 4.2% to 2.8% in week 2
after Google updated their core algorithm. Here's exactly 
what we did to recover — and the specific A/B test data.

E — Expertise

Does the author know this topic deeply?

Signals:

• Author bio with relevant credentials
• Consistent coverage of the topic over time
• Technical depth when needed
• Certifications or formal training (where relevant)

About the author: Sarah has managed $2M+ in ad spend 
across 50+ SaaS launches. She's certified in Google Ads 
and has been writing about growth since 2019.

A — Authoritativeness

Is the author recognized as a leader in this space?

Signals:

• External sites citing your content
• Guest posts on authoritative publications
• LinkedIn endorsements or testimonials
• GitHub stars, open source contributions
• Podcast appearances, interviews

This method was also covered in [TechCrunch](link),
[HackerNews](link), and recommended by [famous person](link).

T — Trustworthiness

Is the information accurate and safe to act on?

Signals:

• Contact page, about page, clear identity
• Privacy policy, terms of service
• Verifiable claims with data sources
• Corrections or updates to old content
• Secure (HTTPS) site

E-E-A-T for AI Search (ChatGPT, Perplexity)

AI engines weight E-E-A-T differently than Google:

AI SEO = E-E-A-T × Specificity

Generic content with strong backlinks won't get cited by AI. Specific, experience-rich content with moderate backlinks will.
