At some point, every restaurant owner sees the ad: fifty five-star Google reviews, £50, delivered in a week. When you are sitting at eleven reviews and the place across the road is at two hundred, it looks tempting. Here is the honest breakdown of what actually happens — mechanically, legally, and commercially — because buying reviews is one of the few moves that damages your profile, your wallet, and your legal position at the same time.
The filter catches a share immediately
Every review passes through Google's spam detection before it goes live. Fifty five-star reviews arriving in a week, from accounts with no history, with similar wording, posted from a handful of devices — that is not a pattern a filter misses. Some will never appear at all, some will appear briefly and then vanish in batches, and you will not be told which is which or why. The mechanics of that filter — including why genuine reviews get caught in the same net — are worth understanding: why Google reviews sometimes do not show up.
The purge pattern
Bought reviews that survive initially tend to die in a purge — a periodic sweep, often after Google's systems link the seller's accounts together (and fake-review sellers' accounts always get linked, because they reuse them). The telltale aftermath: a rating that held at 4.8 for two months suddenly drops to 4.3 in an afternoon when thirty reviews disappear. Your rating is not just back where it started — it is now visibly unstable, and a rating that visibly fluctuates in steps reads as manipulated to the customers who notice. Meanwhile the sellers move on to the next restaurant.
It is illegal — and getting more so
In the UK this is not a grey area. Since April 2025, the Digital Markets, Competition and Consumers Act makes it a banned practice to submit, commission, or publish fake reviews, with CMA fines that can reach 10% of global turnover. The buyer is caught alongside the seller. Before that, the practice was already actionable under consumer law, and the CMA has gone after fake-review sellers repeatedly. The full legal picture is in our guide: are fake Google reviews illegal?
The commercial arithmetic nobody mentions
Set the law and the filter aside. Suppose half the bought reviews stick. Do they even help? Not the way genuine ones do:
- Customers read reviews, not just ratings. Fake reviews are generic by nature — "great food great service" — because the writer has never eaten there. Against a competitor whose reviews name dishes, servers, and moments, generic praise reads hollow.
- Fakes do not convert. A review exists to remove a stranger's doubt. A profile full of hollow five-stars removes doubt about exactly one thing: that the reviews are hollow.
- You paid for an asset you do not own. Those reviews belong to the seller's accounts, not your business. When the accounts get banned — they will — the asset evaporates with them.
The part that takes longest to rebuild
Here is the real cost. Businesses caught with fake reviews — or that acquire the burst-and-purge pattern — face the slow rebuild: every genuine review from then on is judged against the suspicion. Google's systems trust a profile less after manipulation, which means more of your genuine reviews get filtered too. You have not just wasted £50; you have taxed every honest review you earn for the foreseeable future. And if a competitor or a journalist runs your profile through a fake-review checker, that is a story that outlives the rating.
What works instead — the boring truth
The venues that win at reviews do the unglamorous thing: they ask every customer, they make leaving a review take thirty seconds, and they let the reviews be real — including the mixed ones, because a 4.6 with texture converts better than a suspicious 5.0. The exact ask scripts are in how to ask for a Google review, the volume strategy is in getting more reviews honestly, and the tool that removes the friction — printed Google review cards with a QR that opens the review flow — is the whole reason Revly exists.
Revly never writes or fakes a review: the customer taps their experience, edits an AI-assisted draft, and posts it themselves. Genuine volume, collected honestly. (Revly is currently running a free pilot — the first 50 cafés get everything free.) See the demo page or get in touch.
