The short answer

Google removes reviews automatically when its filters flag them, most often for policy breaches, suspicious patterns or because the reviewer's account was removed. There is no notification and usually no explanation. Genuine reviews caught by mistake can sometimes be recovered by reporting them, but a review removed for a real policy breach is gone and will not come back.

You had forty-two reviews. Now you have thirty-five. Nobody told you, nothing in your dashboard explains it, and the seven that vanished were real customers.

This happens more than most owners realize, and the reasons are usually knowable even though Google will not tell you which one applies.

First, rule out the boring explanations

Before assuming a filter caught you, check three things that look identical from the outside.

The reviewer deleted their Google account. When an account goes, everything it posted goes with it. Nothing to do with you and nothing you can do about it.

The reviewer deleted the review themselves. People do this, sometimes years later, sometimes for reasons unrelated to your business.

You are looking at a duplicate profile. If your business has more than one Google Business Profile, reviews split between them and it can look like some vanished. Search your business name and see how many versions of you exist. Duplicates are common after a move, a name change or a rebrand, and they genuinely harm you beyond the confusion.

If none of those explain it, the filter caught them.

Why Google removes genuine reviews

The filters are automated and they are blunt. They are aimed at review fraud, which is a real and large problem, and they catch honest businesses in the sweep.

A burst of reviews in a short window. This is the most common cause and it usually happens to a business that just started trying. You finally ask twenty customers, fifteen leave a review in three days, and the pattern looks purchased. A steady trickle almost never trips this. A sudden spike often does.

Several reviews from the same network. If you hand your tablet to customers in the waiting room, or ask staff to review from the office wifi, those reviews come from one IP address and get flagged as coordinated.

Reviews from accounts with no other history. A brand new Google account whose only ever activity is a five-star review of your business looks manufactured, even when the person is a genuine customer who made an account specifically to thank you.

Anything that reads as incentivized. Mentioning a discount, a draw entry or a free service in the review text is a policy breach on its face, and it can take neighbouring reviews with it.

Text that trips a content rule. Naming staff members in some contexts, links, contact details, or anything read as offensive. Also, occasionally, reviews that mention a competitor by name.

What you can actually recover

Be realistic here, because the recovery rate is not high.

If a genuine review was caught by mistake, you can report it through your Google Business Profile support. Have the specifics ready: the reviewer's name, roughly when it was posted, and confirmation they were a real customer with a record in your system.

Expect this to take weeks and expect it to fail more often than it succeeds. Google errs toward leaving removals in place, because the alternative is reinstating fraud.

A review removed for an actual policy breach is gone. If it mentioned the discount you offered, no appeal will bring it back, and pushing the point invites a closer look at the rest of your profile.

The part that matters more than recovery

Chasing seven lost reviews is usually the wrong use of your afternoon. Preventing the next removal is worth far more, and it comes down to one change.

Ask continuously instead of in bursts. Five a month forever is both better for your ranking and far less likely to trip a filter than sixty in a campaign. The steady pattern looks like what it is, which is a business quietly doing good work.

Alongside that:

Send a direct link by text and let people review on their own phone, on their own connection, in their own time. Never on your device or your wifi.

Never offer anything in exchange. Not a discount, not a draw, not a free session. It breaks the rules, it puts every other review at risk, and it works less well than simply asking at the right moment anyway.

Ask everybody who finished a job, not only the ones you are certain adore you. Selective asking produces a small, suspiciously perfect profile that convinces nobody.

If you want the full method rather than the cautions, the asking process is here.

A note on timing

Some businesses see reviews vanish and then reappear days later. The filters run continuously and occasionally reverse themselves.

So before you spend an evening on support forms, wait a week and look again. A meaningful share of disappearances resolve on their own, and there is nothing you can do to speed that up.

Common questions

Why did Google delete my reviews without telling me?

Google's filters run automatically and it does not notify businesses when a review is removed. There is no log in your dashboard either, which is why owners usually notice only when the count drops.

Can I get deleted Google reviews back?

Sometimes, if a genuine review was caught by mistake. Report it through Google Business Profile support with the reviewer's name, the approximate date and evidence they were a real customer. Success rates are modest and a review removed for a real policy breach will not return.

Does asking lots of customers at once get reviews removed?

It can. A sudden spike after a long flat period is one of the most common patterns the filters flag. A steady few each month is safer and better for your ranking.

Can reviews left on my office wifi be removed?

Yes. Multiple reviews from one IP address look coordinated to the filters. Send a link by text so people review on their own connection instead.

Will offering a discount for reviews get me in trouble?

Yes. Incentivized reviews breach Google's policies, the review itself is likely to be removed, and it can put the rest of your profile under scrutiny. It is the one shortcut genuinely not worth taking.
