When a potential customer searches for a plumber in Sacramento, Google isn't just looking at keywords. It's asking: Can this business be trusted?
That's where E-E-A-T comes in. It stands for Experience, Expertise, Authoritativeness, and Trust. Originally used for medical and financial sites, it's now critical for local service businesses—especially in California, where licensing and regulations vary by county.
In this guide, we'll show you exactly how to build E-E-A-T signals on your website, starting with the essentials: licensing, bonding, insurance, and more.
What Is E-E-A-T and Why Does It Matter?
Google's Search Quality Rater Guidelines use E-E-A-T to evaluate content quality. While not a direct ranking factor, pages with high E-E-A-T tend to rank better because they satisfy user intent and demonstrate trustworthiness.
For local service providers, E-E-A-T translates to:
- Experience: You've done this work before. Show case studies, photos, years in business.
- Expertise: You know your trade. Display licenses, certifications, training.
- Authoritativeness: Others recognize you. Get reviews, mentions, awards.
- Trust: Customers can rely on you. Highlight bonding, insurance, guarantees.
The Foundation: Licensing, Bonding, and Insurance Pages
In California, many trades require state licensing (Contractors State License Board for contractors, etc.). Displaying your license number prominently builds trust and satisfies legal requirements.
Don't bury this information in the footer. Create dedicated pages for:
- Licenses & Certifications: List all your credentials with numbers and issuing bodies.
- Insurance & Bonding: Explain what coverage you carry and why it protects customers.
- Safety & Compliance: If you follow specific safety protocols, mention them.
"We are licensed by the California Contractors State License Board (CSLB #123456). This means we've passed exams, undergone background checks, and maintain continuing education. You can verify our license at cslb.ca.gov."
Showcasing Experience: Portfolio, Case Studies, and Photos
Experience is best shown through real work examples. Include:
- Before/after photos of projects (with permission).
- Case studies describing challenges and solutions.
- Timeline or "years in business" counters.
Add geotags to photos to reinforce local presence.
Demonstrating Expertise: Author Bios and Certifications
If you have employees with specialized training, feature them. Create an "About Us" or "Team" page with:
- Professional headshots
- Bio highlighting experience and certifications
- Links to their credentials (if public)
Pro Tip:
Each team member can have their own author bio on blog posts they contribute to, signaling expertise to Google.
Building Authoritativeness: Reviews, Mentions, and Backlinks
Authoritativeness is about reputation. Google looks for third-party validation:
- Google Reviews: Respond to them, encourage happy customers to leave detailed reviews.
- Industry associations: BBB, Chamber of Commerce, trade groups.
- Local media mentions: If you've been featured in news or blogs, display "As seen in" badges.
- Backlinks from local .edu or .gov sites: Sponsor a little league team, get listed on city websites.
Trust Signals: Guarantees, Warranties, and Clear Policies
Trust is the culmination of all the above, plus explicit promises:
- Satisfaction guarantee: "If you're not happy, we'll make it right."
- Warranty on workmanship: Typical 1-year, 5-year, etc.
- Clear contact info: Phone, email, physical address (if applicable).
- Privacy policy and terms: Especially if you collect personal data.
