The average Adelaide cleaner is rated 4.7 stars. On 14 reviews.

When our transparency study found that not one of 94 Adelaide commercial cleaning websites publishes a firm price, the obvious comeback was: who cares — just check the reviews. So we did. Same 106 companies, Google Business Profile ratings and review counts, matched conservatively (when we could not be confident a listing belonged to the Adelaide business, we counted it as not found). Here is what the stars are actually standing on.

What the ratings are built on

30 of 106 have no Google review presence at all. 17 have no findable listing for their Adelaide business; 13 more have a listing with zero reviews. More than a quarter of the market is star-invisible.

14 reviews is the median, among companies that have any. That is the entire public evidence base for the average operator — fourteen opinions, accumulated over years.

36 companies hold a perfect 5.0 rating. The median number of reviews behind a perfect score: seven. A flawless record is easiest to hold when almost nobody has voted.

4.68 stars is the market's average rating. Two-thirds of rated companies sit at 4.8 or above. When nearly everyone is excellent, the stars stop ranking anyone — a 4.9 tells you almost exactly what a 4.8 does.

Stars measure visibility, not competence

Here is the honest part, and it cuts both ways. Some of the largest, most established commercial cleaners in South Australia have no Google presence at all — because a pure business-to-business operator wins work through tenders and relationships, and no facilities manager has ever thought to leave them a star. Meanwhile a rating built on a handful of reviews is statistically closer to a coin flip than a verdict. So the absence of stars does not mean bad, and five of them does not mean good. For a commercial decision, the rating is mostly measuring whether the company has ever asked its happiest customers to vote.

The sweep also caught the churn the stars never show: listings marked temporarily or permanently closed, businesses absorbed into other brands mid-listing, and — from the original study — 12 of 106 websites that no longer load. A star rating is a photograph of a moving target, usually an old one.

Sarto has no Google reviews either

We are pre-launch; zero reviews is exactly what we should have, and pretending otherwise would put us on the wrong side of our own study. But it is also why the platform is not built on star-begging. The proof we offer is structural: the price is published, the scope is published, and every visit produces photographs of your site against that scope — evidence about your building this week, not fourteen opinions about someone else’s. Reviews will come, and we will take them; we would just never ask you to buy on them. The quote translation guide covers the rest of the evidence a provider should be able to show you.
