Most diesel shop websites were built by a generalist agency that started with a "trades" template and swapped in truck photos. The hero says "Your trusted partner in mobile diesel solutions." There's a sliding banner. The phone number is buried. The services page lists every brand you've ever touched in alphabetical order. None of it converts a real fleet manager who's standing next to a downed truck.
A diesel website has one job: turn a Google click into a phone call. Every design choice should serve that. Below, the four-page minimum we ship for our shops, and the trust signals that move conversion from 2% to 7%+.
The four pages that actually matter.
Home — phone number above the fold
Hero with shop name, three services (heaviest hitters), call button at the top right, and a one-line proof: "30 years on Class 8 trucks. 4.9 stars across 240 reviews." That's the whole top of the page.
Services — one page per service
Don't list 40 services on one page. Build a separate page per service: injector replacement, DPF cleaning, DOT inspection, transmission, etc. Each page targets one keyword cluster, names brands, and shows pricing ranges.
Fleet — a dedicated capability page
Specifically for fleet managers. Bay count, hour-rate, brands serviced, equipment owned, current customers (logos if allowed), one-page capability PDF download. This is the page that closes a 30-truck account.
Contact — phone, map, hours
Phone number huge. Map embed. Hours listed (including after-hours line if you offer it). Form is secondary — trucks call, they don't fill out forms.
The hero isn't a slogan.
It's a phone number.
Trust signals a diesel buyer actually reads.
- Years in business — "Family owned since 1991" beats every certification on the page.
- Specific brands serviced — Cummins, Detroit Diesel, Paccar, Volvo, Mack, ISB, ISX, X15. Brand-name signals tell a fleet manager you can actually do the work.
- Equipment list — JPRO, Cummins INSITE, Detroit Diagnostic Link, DPF cleaning machine, frame straightener. Lists like this signal capability faster than any bullet of marketing copy.
- Photos of trucks in bays — Real trucks. Real bays. Real techs. Stock photography is an instant trust killer.
- Reviews on the page, not just on Google — Pull 6–10 of your best Google reviews onto the homepage with full text and customer name.
- One verifiable customer — "Reference: Mike at ABC Trucking, [phone]" if they've agreed. Nothing closes a fleet account faster.
What to cut.
The hero slideshow.
Nobody waits for slide three. Pick the one most important message and keep it static.
Stock truck photos.
If a fleet manager can reverse-image-search and find your "best mechanics in [city]" photo on a shop in three other states, you've lost the trust battle.
The "About Us" novel.
Three sentences and a photo of the owner. Anything longer is for you, not the customer.
The contact form as primary CTA.
Diesel buyers call. Forms convert at 1%. Phone buttons convert at 7%+. Stop optimizing for the lower number.
Mobile is the entire game.
80%+ of diesel queries happen on a phone, often standing next to a broken truck. If your site loads in five seconds, you've already lost half. If your phone number isn't tappable above the fold, you've lost the rest. Mobile-first isn't a design philosophy for diesel shops — it's the actual battlefield.

We rebuild our shops' websites as part of onboarding when needed — built around conversion, tracking, and the diesel buyer's actual decision flow.
