A Trusted Electrician.
Reviews AI Couldn’t See.
Craig Diehl earned 4.9 stars across 130+ reviews in and around Lodi. His old website kept that proof off the page where AI could read it. Digilu rebuilt it so the trust leads, and the machines can finally see it.
Six Pillars of AI Trust. Measured, Not Estimated.
AIOInsights scores a site on six pillars of AI trust visibility. Best Diehl Electric's old site failed on the pillars that matter most for a local electrician business. After the rebuild, the score reads 9.6 of 10. Both numbers were measured live on the same engine (AIOInsights v2.3.1) on the same day, the old site against the new one.

A Reviewed Electrician a Plain Site Was Holding Back
Craig Diehl runs Best Diehl Electric, an owner-operated, licensed C-10 electrical contractor doing residential and commercial electrical work in Lodi, California. Homeowners and businesses across the area call him when the work has to be done right. The reputation is real: a 4.9 rating across 130+ reviews, with an A rating with the BBB.
Craig found Digilu through a free AIOInsights check. The check measured one thing: how visible his trust signals were to the AI systems that increasingly decide which electrician gets recommended. The verdict was blunt. His site scored a 7.9 out of 10, with the two pillars that matter most for a local trade, Trust and Local Presence, sitting at a 2.
The reviews existed. 119 on Google, 13 on Angi at 92 percent five-star, an A with the BBB. But they lived on a plain template that carried no structured data. To a language model reading bestdiehlelectric.com, the single most persuasive thing about the business, its 4.9 across 130+ reviews, was effectively invisible.
The gaps the check found
- Trust (2.0): no
AggregateRatingin the structured data, so AI could not see his 4.9 rating across 130+ reviews from his own site. - Local Presence (2.0): no Google Maps link and no service-area structure for the cities he covers.
- No
llms.txt: a missed AI-discoverability opportunity, with little a modern crawler could parse about the business.

The Template Became a Business
The old site opened with a plain template that pushed Craig, the reviews, and the proof off the page. The rebuild flips it so trust leads. Here is what came first, what replaced it, and the score it produced.
What came first. A plain template with a typeset B.D.E. wordmark, the owner buried, and nothing a machine could read about the 4.9 rating or the cities he serves.
What we built. A gold-and-black Trust Seal design that leads with Craig, his 4.9 rating, and the reviews behind it, all of it written as structured data an AI model can read.
People and AI assistants size up an electrician in the first few seconds, on the trust they can actually see. Craig had 130+ real reviews, but a plain template kept them off the page and wrote nothing a model could parse. Leading with the proof, and encoding it as structured data, fixed the thing that was really holding the business back.
A New Brand, Built to Be Trusted
Best Diehl Electric did not just get a new website, it got a new brand. Digilu replaced the typeset “B.D.E.” initials and the muted navy-and-amber theme with a real Trust Seal mark and a sharper black-and-gold system, built on the gold-and-black heritage Craig already had.

130+ reviews on Google, Angi, and the BBB, plus an A rating with the BBB.
He Already Had the Trust. It Just Wasn’t Reaching AI.
This is the part most marketers get wrong. Best Diehl Electric did not need a louder pitch. It had a wall of five-star reviews and an A with the BBB. The problem was structural: that reputation never made it into a form an AI model could read off the business’s own website.
We published his real aggregate rating as AggregateRating structured data, added Review objects, and marked the business up as a literal LocalBusiness / Electrician. Now when an AI system reads his site, the first thing it learns is that real customers trust him, and exactly how much.
His biggest asset went from invisible to the first thing both people and machines see. Trust and Local Presence both moved from a 2.0 to a 10, lifting the overall score from 7.9 to 9.6.
What Digilu Built
A plain template became a real business presence, built to the standard that earns a 9.6.
Machine-Readable Trust
Real AggregateRating and Review structured data so AI systems can finally see the 4.9 rating and the 130+ reviews behind it, straight from the business’s own site.
City Service-Area Pages
Distinct city pages for Lodi, Sacramento, Elk Grove, Stockton, Galt, Lockeford, and Acampo, each with local content, a Maps link, and its own schema.
AI Discoverability Layer
An llms.txt file, an AI-crawler-friendly robots.txt, a clean sitemap, an entity graph, and literal LocalBusiness / Electrician schema so modern crawlers can find and trust the site.
A Trust Seal Brand
A gold-and-black design system on Craig’s heritage colors, a real Trust Seal logo, and the tagline “electrical work done right,” replacing the plain wordmark that buried him.
A Review-Generation Engine
A dedicated review page, a QR code for business cards, and a guide to leaving a Google review without a Gmail account, so the wall of reviews keeps growing.
Lead Capture That Works
A contact form that emails Craig directly, plus phone and quote calls to action on every page, turning new visibility into real conversations.
A Case Study That Keeps Score

Each bar is a real monthly reading from the live AIOInsights engine. As the site earns real traffic and results, winning performance metrics will be added here too.
The trust was always there. Visibility was the missing piece.
A 9.6 is not the goal. It is the evidence. Best Diehl Electric proves what the trust thesis predicts: when a business already deserves to be chosen, the work is not manufacturing trust, it is making the trust legible to the systems doing the recommending.
Search is changing. People ask an AI assistant which electrician to call before they ever open a map. The businesses that win that question are the ones whose proof is machine-readable. Craig’s customers always trusted him. Now the machines can read why.
That is the thesis. Best Diehl Electric is the proof.
