Six tests, ten minutes
Do these standing on your own forecourt, on mobile data, not the office wifi. That is where the customer is deciding. Score each pass or fail, then fix in the order the failures come.
1. Read the wash menu without tapping twice
The test: open the site and find the price of your mid-tier wash.
Pass: a menu with every wash and its price, one tap from the home page, and you can edit it yourself when prices move.
Fail: a PDF, a photograph of a sign, or "see forecourt for prices".
The fix: a real price table you control. A car wash competes on a number a driver can see in three seconds; a PDF loses to the site down the road that shows it.
2. Buy a membership without visiting
The test: try to sign up for your monthly plan from the site, on a phone, as a new customer.
Pass: tiers explained side by side, the plate or QR link explained in one sentence, and payment taken online.
Fail: "ask at the kiosk". This is the single biggest gap on most car wash sites — the plan is the profitable product and it is only sold to people already standing in front of you.
The fix: sell the tiers online and link the plate or tag at signup. Washify and DRB both do the plate side; Square Appointments, Booksy or Acuity handle the payment if your plan is simple.
3. Book a hand wash or valet into a real slot
The test: book tomorrow morning for a full valet.
Pass: live slots that land in your diary, with the duration blocked correctly for a valet rather than a tunnel wash.
Fail: an enquiry form, or a phone number and opening hours.
The fix: put the valet and hand wash side of the business on live booking. The tunnel does not need it; the labour-bound services do, because those are the ones you lose when nobody answers.
4. Appear in under two seconds
The test: on mobile data, count until the menu or the main heading is usable.
Pass: under two seconds.
Fail: a hero video of a car being foamed, a slider, or a chat bubble loading on every page.
The fix: one compressed image, no slider, and the booking script loaded only when the button is tapped. Forecourt traffic is impatient traffic.
5. Answer a fleet enquiry properly
The test: look for anything aimed at a company with twelve vans.
Pass: a fleet page with terms, invoicing, and an enquiry form that captures vehicle count.
Fail: nothing, so fleet work only arrives when a manager happens to drive past.
The fix: one honest page. Fleet contracts are the highest-value thing a car wash sells and almost no competitor has a page for it.
6. Be findable at the moment of need
The test: search your town plus "car wash" on a phone.
Pass: correct hours and location markup so Google shows you as open, plus gift cards purchasable online.
Fail: hours that disagree with your Google profile, which is the fastest way to lose a driver who is already nearby.
The fix: get the hours and location markup right and keep the two in sync. Add gift cards — they cost nothing to list and sell themselves in December.
Scoring
Six passes and the site is doing its job; spend the money on advertising instead. Four or five, fix the failures and leave the rest. Three or fewer and the structure is wrong — patching it will cost more over two years than rebuilding once.
Where this sits
Our car wash websites are built to pass all six at a fixed price. The wider trade version is on the automotive page. Run the six on your two nearest competitors as well; most fail the membership test.
