5.7 E-E-A-T: Building Authority
The Four Components in Plain Language
- Experience -- You have actually done the thing you're writing about. Used the product, visited the place, worked in the field. First-hand knowledge -- not rehashed content from other websites.
- Expertise -- Demonstrable knowledge through credentials, education, or a proven track record. For health, legal, and financial topics, formal qualifications carry heavy weight.
- Authoritativeness -- External recognition. Other credible sources cite you, link to you, or mention you as a go-to source in your field.
- Trustworthiness -- The most important pillar. Google explicitly states "Trust is the most important member of the E-E-A-T family." It depends on transparency, accuracy, and security.
Google's Self-Assessment Questions
Google publishes these questions in their Search Central documentation. Ask yourself honestly whether your site passes:
- Does the content provide original information, reporting, research, or analysis?
- Does the content provide insightful analysis beyond the obvious?
- Does the content have a primary audience that would find it useful outside of search?
- Does the content demonstrate first-hand expertise and depth of knowledge?
- Does the content leave the reader feeling they have learned enough to achieve their goal?
If any answer is "no," that page is vulnerable to ranking losses in future core updates.
Step-by-Step: Demonstrating E-E-A-T for an SMB
Build a proper About page
Not a paragraph -- a real page. Include: who you are, your qualifications and credentials, how long you've been in business, your story (why you started), and photos of you and your team. Link to professional registrations, industry memberships, and certifications. This page is read by Google's quality assessment systems and by every customer who's deciding whether to trust you.
Add author bios to content
If you publish blog posts, guides, or articles, add an author byline and short bio with credentials to each one. "Written by [Name], [Qualification], [Years] years in [industry]" tells both Google and readers that a real expert wrote this. Link the author name to your About page.
Use real photos and evidence of work
Upload photos of actual projects, actual team members, and actual results. Include case studies with specific metrics. "Before and after" photos of your work are powerful E-E-A-T signals because they demonstrate experience -- you actually did the work, and here's the proof.
Display credentials and memberships
Industry association logos, professional certifications, licensing numbers, insurance details, awards. Put them on your About page, your footer, and near CTAs. These are external validation that you are qualified to do what you claim.
Get mentioned on external sites
Authoritativeness comes from what others say about you. Pursue: industry directory listings (section 4.5), local news mentions, guest articles on industry sites, Chamber of Commerce membership, and client reviews that mention specific expertise. Each external mention is a trust signal Google can verify.
Keep your business information transparent
Clear contact information on every page. Physical address visible. ABN displayed. Privacy policy. Terms of service. These seem mundane but Google's quality raters check for them. Missing contact info or hidden business details are red flags.
E-E-A-T is not just for Google. AI engines like ChatGPT, Perplexity, and Google's AI Overviews also use authority signals when deciding which businesses to recommend. 96% of AI Overview citations come from sources with strong E-E-A-T signals. Building authority for SEO simultaneously builds authority for GEO.
Google's December 2025 update specifically targeted pages that summarise existing top-10 results without adding original data, first-hand experience, or a unique perspective. AI-generated content is not automatically penalised -- but it must meet all quality standards. In practice, most AI-generated content fails because it lacks original insights and first-hand expertise.
