# Building E-E-A-T and Authority ## Overview E-E-A-T is not a direct ranking factor — it's the **weighting framework** Google's quality raters apply to evaluate whether a page deserves to rank, and AI engines (ChatGPT, Claude, Perplexity, Gemini) have learned an almost identical pattern. **96% of AI Overview citations come from sources with strong E-E-A-T signals** (r=0.81 correlation) [1][6], and content from authors with verifiable credentials gets cited **~40% more often** by AI engines [2]. In 2026, E-E-A-T is an active filter, not a tiebreaker. Solo founders and small teams **can** build E-E-A-T from zero, but it is a 6-month minimum game. Plant the seeds before you need the shade. The example throughout: **vibecrafting.ai** — a solo-founder product site, no fortune-500 pedigree, building authority in the "vibe coding" / AI-assisted dev space. ## The 4 pillars in 2026 - **Experience** (added Dec 2022 [3]) — first-hand evidence you've actually done the thing. Weighted heavily for product reviews, travel, finance, parenting, and any "I tried it" content. For vibecrafting.ai: screenshots of real projects shipped, dated build logs, "I shipped 14 apps with this workflow" beats "10 best AI coding tips." - **Expertise** — credentials *plus* demonstrated knowledge depth. Less about degrees in 2026, more about specificity, accuracy, and information gain (Google's March 2026 core update made Information Gain the dominant content-quality signal [7]). - **Authoritativeness** —
