The old site was a placeholder that had never been finished
One page, and every link in the navigation went nowhere — parts, cars, about, contact, warranty, shipping, privacy, terms. It also listed specific vehicles, prices and inventory counts that did not correspond to anything real, which is worse than having no site at all.
The shop had moved, and the internet had not been told
The new address was right in one place and wrong in most others. Name, address and phone disagreeing across services is one of the strongest suppressors of local ranking there is, and it is invisible from the inside — the owner sees the one listing he checks.
Apple Maps was sending customers to a directory site
The listing carried the previous address, and its website field pointed at a review directory rather than at the business. Apple Maps was handing the shop’s own traffic to somebody else.
There was no email on the business’s own domain
A free consumer address on every quote and invoice. The cheapest credibility problem there is to fix, and one of the most visible.
