Mobile Diagnostics — On-site Car Diagnostics

Astro website (no CMS) for mobile car diagnostics with OEM dealer equipment + an AI diagnostic assistant (Claude): symptom/OBD-code guidance and booking right in the chat.

About the Project

Mobile Diagnostics is a service where the specialist comes to your address with original dealer (OEM) equipment and reads exactly what the dealership would read — at your doorstep or on the road. The site started on WordPress, but we rebuilt it completely on Astro — no CMS, no plugins: one fast, lean page built around how customers actually call — "can you come to me, for my make, today". Front and center sits an AI diagnostic assistant: describe a symptom or paste an OBD code, get an initial direction, and book an on-site visit right in the chat.

A four-step path from call to diagnosis, written in plain language
Coverage block: home, office or roadside — Sofia and the region

What Makes It Special

The rebuild replaced a generic CMS site with a focused sales page that loads instantly and answers the three questions every caller has: do you cover my brand, do you come to me, what happens next. The AI assistant qualifies the inquiry before the call — symptom in, direction out, booking captured. Combined with LocalBusiness + FAQ schema, the site earns its traffic organically — no ad budget.
