Reviews are the cheapest ranking and conversion lever a detailer has, and the easiest one to get wrong. The temptations are obvious: ask only the happy customers, throw in a free wash for five stars, get the family to post a few. Every one of those is against Google's policy, and in the US, UK and Australia at least one is now against the law. Here is what the rules say, what the numbers say, and a system that gets reviews steadily without any of it.

What Google's policy bans

Google's Maps user-contributed content policy is short and specific. Prohibited content includes "reviews or ratings that have been paid for, directly or in kind" and content "posted from multiple accounts by or at the request of one person". Merchants must not "offer incentives – such as payment, discounts, free goods and/or services – in exchange for posting any review or revision or removal of a negative review", and must not "discourage or prohibit negative reviews, or selectively solicit positive reviews from customers". That last line is the one most detailers break without knowing: sending the review link only to customers who said they were happy, or asking "how did we do?" first and routing the unhappy ones to a private form, is review gating, and Google removes reviews and can suspend profiles for it.

Google also says, on its local ranking page, that "more reviews and positive ratings can help your business's local ranking" and that "there's no way to request or pay for a better local ranking on Google". So the reviews are worth having. They are just not worth faking, and Google's filters are good enough now that a burst of five-star reviews from accounts with no history is more likely to be removed than to help.

The law, briefly

Three regulators cover Detail Up's markets. In the United States, the Federal Trade Commission's rule of 14 August 2024 bans fake reviews, bans "compensation or other incentives conditioned on the writing of consumer reviews expressing a particular sentiment, either positive or negative", requires insiders such as owners and staff to disclose their connection, and lets the FTC seek civil penalties against knowing violators. In the United Kingdom, the CAP Code (rule 3.47) requires advertisers to hold documentary evidence that a testimonial is genuine and contact details for the person who gave it, and the ASA treats a fake or edited review as a misleading advertisement. In Australia, the ACCC's guidance on online reviews is that businesses must be transparent about commercial relationships, must not post or publish misleading reviews, and that "omitting negative reviews can be as misleading as posting fake reviews". The common thread: incentives tied to a positive review, staff or family reviews without disclosure, and hiding the negative ones are all off the table.

What the numbers say (US data)

BrightLocal surveys US consumers each year. Its 2024 survey found that 75% of consumers always or regularly read online reviews, that 71% would not consider using a business rated below 3.0 stars, and that 76% expect a rating between 4.0 and 5.0. The most useful statistic for a detailer is about replies: 88% of consumers would use a business that replies to all of its reviews, compared with 47% for a business that does not respond. The 2025 survey (1,026 US consumers) found only 4% of people never read reviews, that Google is the platform used by around 87% of them, and that 63% expect a reply to their review within a week. These are American consumers, but there is no reason to think a driver in Leeds or Brisbane behaves differently when picking someone to polish their car.

A post-job review system that runs itself

The goal is a steady flow of two to four reviews a week, every one of them from a real customer, asked the same way, with no filtering. Steady beats bursts: Google's ranking guidance rewards prominence built over time, and a profile that gains reviews every week looks like a business that does work every week.

  1. Ask at handover, in person. Walk the customer around the car in daylight, point out two things you fixed, and say: "If you're happy with it, a Google review helps me more than anything. I'll text you the link." Ask everyone. Not just the ones who are gushing.
  2. Send the link within an hour. One SMS with your direct review link (the short link from your Business Profile), the customer's first name and one sentence. "Thanks for today, Sarah. Here's the link if you have a minute: [link]." No stars, no instructions on what to write, no offer.
  3. One reminder, three days later. "No pressure, but if you get a minute the review link is here: [link]. Thanks again." Then stop.
  4. Reply to every review within 48 hours. Name the service and the vehicle ("Glad the two-stage correction on the Golf came up well"), because the reply is indexed too and it is where your service keywords belong. Reply to the bad ones with the fix you offered and nothing else.
  5. Put the reviews to work. Pull the best three onto the relevant service page with the customer's first name and suburb, as written. Do not edit them beyond trimming length, and do not use one from a different service on your coating page; the ASA and FTC both require testimonials to relate to the product advertised.
  6. Track the ratio. Jobs done divided by reviews received. A good detailer with this system lands one review for every three to five jobs. If the ratio is one in twenty, the ask at handover is being skipped.

What not to do, in one list

  • No discounts, free add-ons, gift cards or entry into a draw in exchange for a review, positive or otherwise.
  • No review kiosks or "leave a review on my phone now" at the job; Google flags multiple reviews from one device and location.
  • No pre-screening. The unhappy customer gets the same link as the happy one, and a fixed problem and a public reply is worth more than a hidden complaint.
  • No reviews from staff, family or your own accounts. If a staff member genuinely used the service, the review must say they work there.
  • No bought reviews from any platform, ever. They are removed, the profile is flagged, and in the US it is now a federal offence.
  • No asking a customer to mention a keyword. You can ask them to describe the job; you cannot script it.

What to do next

Set up the handover ask, the one-hour SMS and the three-day reminder this week and run it for a month. Detail Up builds the review request into the post-job sequence on every client account as part of Google Business Profile management, with the tracked number doing the sending. Book a call.
