The Four Dimensions of E-E-A-T
- Experience: Did the person who wrote the content actually live it? Did they use the product firsthand, or work in that industry? Google tries to distinguish theoretical knowledge from real-world experience.
- Expertise: Is the author sufficiently knowledgeable? In fields like medicine, law, and finance, documented expertise is critical. But for blog-style content, 'lived expertise' also counts.
- Authoritativeness: How well-known are you in your sector? Do other trusted sites reference you? Does your name appear in sources related to that topic?
- Trust: Everything else feeds into this. Does your site show contact information? Is the author identifiable? Are sources cited? Trust is the core of E-E-A-T.
Why Does E-E-A-T Matter More for YMYL Topics?
Google classifies certain topics as 'Your Money or Your Life' (YMYL) — areas like health, finance, law, and safety where incorrect information can cause real harm. For these pages, Google sets the E-E-A-T bar significantly higher. If your business falls into these categories, your site's trust signals deserve extra attention.
On an e-commerce site, product reviews written by real buyers strengthen that page's 'Experience' signal. A human voice saying 'we used this product for six months' is far more valuable to Google than generic company-branded copy.
How Do E-E-A-T Signals Work in the AI Era?
Generating content with AI has become very easy. That's why Google is placing more weight on answers to questions like 'who wrote this?' and 'why should we trust it?' Features like AI Overviews also prefer content with transparent, verifiable sources. Author pages, real names, published articles in the sector, press mentions, and citations from trusted sites — all of these are becoming more important.
- Include a real author name and short biography on every blog post or product page.
- Cite the sources behind claims in your content; link to official reports or research.
- Keep your contact page complete: phone, email, physical address.
- Publish customer testimonials and case studies with real names and industries.
- Seek references and citations from other trusted sites and publications in your sector.
- Update your content regularly and include a publication date and 'last updated' note.
A site with no author biography, incomplete contact information, and unsourced claims carries no trust signal in Google's view. This can hurt your rankings no matter how strong your technical SEO is.
