Fake Google reviews don't expire on their own. Google doesn't have a clock running in the background that quietly deletes reviews once they hit a certain age. A fake review from three years ago can sit on a business profile just as easily as one from three weeks ago, and it will stay there indefinitely unless something else takes it down: a policy violation, a suspended reviewer account, or one of Google's periodic spam sweeps.
That last part is where most of the confusion comes from. Reviews do disappear all the time, sometimes in large batches, and it's easy to assume age is the trigger when it almost never is. What's actually happening is closer to an ongoing cleanup operation than a countdown timer.
Age alone has never been grounds for removal under Google's review policies. A five-star review posted in 2019 and a one-star review posted yesterday are judged by exactly the same rulebook. If neither breaks a rule, both stay up forever, warts and all.
What changes over time isn't the review's eligibility for removal. It's the odds that Google's detection systems eventually catch something they missed on the first pass. Spam models get retrained, new signals get added, and reviews that slipped through an earlier, cruder version of the filter can get swept up months or years later. From the outside, that looks a lot like expiration. It isn't. It's re-scoring.
Google doesn't read a review and simply decide "this sounds fake." The system is built around behavioral signals that are much harder to fake convincingly than the text itself:
Google confirmed in 2025 that its Gemini model is now part of this pipeline, layered on top of the older rule-based filters rather than replacing them. The older systems still catch the bulk of obvious spam quickly and cheaply; Gemini gets called in on the ambiguous cases, the ones where a review looks fine in isolation but fits a pattern that only becomes visible when you compare it against thousands of others. That combination is a big part of why enforcement has scaled up so sharply: Google reported removing more than 240 million policy-violating reviews in 2024 alone, a jump of roughly 40% year over year.
Google's Prohibited and Restricted Content policy lays out a fairly specific list, and it's worth knowing because "I don't like this review" isn't on it. Reviews get removed when they fall into one of these categories:
A genuinely negative review from a real customer doesn't qualify for removal just because the business owner disagrees with it or finds it unfair. That distinction frustrates a lot of business owners, but it's also what keeps the review system from turning into a tool that only ever shows the good stuff.
Google has also tightened the rules around how businesses collect reviews in the first place. As of the most recent policy update, review gating (asking only your happiest customers for feedback while quietly skipping the rest) is explicitly banned, along with offering any kind of incentive for a review, pressuring customers while they're still on the premises, and directing staff to hit review quotas. Sudden spikes in review volume get flagged as a manipulation signal on their own, regardless of whether the reviews themselves look genuine.
If you manage a business profile and watch your review count fall without warning, a few different things could be going on, and they rarely have anything to do with the business itself:
A reviewer's Google account gets suspended or deleted for unrelated reasons, and every review tied to that account disappears with it. A large-scale spam purge runs across thousands of listings at once, often timed to a broader algorithm update, and catches legitimate reviews alongside fake ones as collateral damage. Or a review that passed the initial screening gets re-evaluated by a newer filter and quietly pulled days or weeks later, with no notification sent to the business.
None of these are things a business can appeal its way out of quickly, and Google has been notably quiet about the scale of these sweeps. Businesses in the same industry or region sometimes lose reviews within the same week, which is usually a sign of a broader algorithm-driven purge rather than anything specific to one listing.
This is the distinction that causes most of the "do reviews expire" confusion. Google's local ranking algorithm does weigh recent reviews more heavily than old ones when calculating how a business shows up in Maps and local search. A business with a steady stream of recent reviews will generally rank better than one whose last review came in two years ago, even if both have the same overall star rating.
But that's a ranking calculation, not a removal decision. An old review isn't deleted because it's old; it just contributes less to how the business is currently ranked. The review stays visible, and a shopper scrolling through will still see it sitting right there next to reviews from last month.
Fake reviews used to be purely a platform-moderation issue. That changed in August 2024, when the Federal Trade Commission introduced a rule that directly bans businesses from writing, buying, or selling fake reviews, with civil penalties that can run past $50,000 per violation. That rule sits on top of whatever Google's own systems catch or miss, which means a fake review that survives Google's filters for months can still expose a business to a federal enforcement action later.
For a business owner, that's a good reason to stop thinking about fake reviews as a "get away with it if the algorithm doesn't notice" problem. For a shopper trying to figure out whether a glowing five-star wave is real, it's a reminder that the review itself is only one data point, and it's worth checking a business's reputation somewhere that isn't relying on a single platform's spam filter to do all the work.
You don't need Gemini-level pattern matching to spot most of the signals that get reviews flagged in the first place. Before trusting a business's star rating at face value, run through this:
Any one of these on its own isn't proof of anything. Several of them stacked together on the same profile is a pattern worth slowing down for. This is exactly the kind of cross-checking WebVouch is built to make faster: instead of manually digging through a review history looking for these patterns, you can pull up a business's trust profile and see the same red flags surfaced without the guesswork.
If you run a business, the practical takeaway isn't to hope a bad review eventually falls off with age, because it won't. The more useful move is to focus on the things that are actually in your control: requesting reviews from every customer equally rather than cherry-picking happy ones, avoiding any language that even implies an incentive, and responding to negative reviews professionally instead of trying to get them removed through a policy loophole that doesn't apply.
Reviews that genuinely violate policy do get caught eventually, often through the same Gemini-assisted layer that's driving the recent spike in removals. Reviews that don't violate policy are staying up regardless of how uncomfortable they are, which is exactly how the system is designed to work.
Nothing about a fake review's age gets it removed. What gets it removed is a policy violation, a suspended account behind it, or a spam sweep that finally catches what an earlier version of the algorithm missed. Recency affects ranking, not survival. And with the FTC now enforcing its own rule against fake reviews on top of whatever Google catches, the incentive to game the system keeps shrinking on both sides. If you're trying to size up a business's reputation before you buy, don't stop at the star rating. Check WebVouch for a fuller trust profile, including the kind of pattern-level red flags that a five-second glance at a review page won't show you.

No. There's no age-based expiration built into Google's system. A review stays visible indefinitely unless it violates a specific policy, the reviewer's account is suspended or deleted, or it gets caught in a spam sweep. Age by itself is never the reason a review comes down.
That pattern usually points to one of two things: a reviewer account was suspended for reasons unrelated to your business (which pulls every review tied to that account), or Google ran a broader spam purge tied to an algorithm update that swept up your listing along with others in your industry or region. Neither is something you did wrong, and neither comes with a notification explaining what happened.
Not on those grounds alone. Google only removes reviews that violate a specific policy, such as fake engagement, conflict of interest, or off-topic content. A harsh but honest account of a real visit stays up even if you disagree with how the customer described it.
Not quite. Recency is a confirmed ranking signal in Google's local algorithm, so a steady stream of recent reviews carries more weight than a pile of old ones, even at the same star rating. The old review stays visible; it just contributes less to how you currently rank.
Gemini acts as an added layer on top of Google's older rule-based spam filters, mainly handling ambiguous cases where a review looks fine on its own but fits a manipulation pattern only visible across thousands of reviews. It's a big part of why removal volume has climbed sharply in the last couple of years, but it works alongside the existing system rather than replacing it outright.
No single method reliably catches AI-written text on its own, and that includes the detection tools built specifically for the job. Most AI detection tools rely on repetitive grammar and lexical patterns in the text, and not concrete data, meaning that they have a very wide margin of error, and can't reliably tell you if you're dealing with AI-generated content.
One test underlies all of the FTC's influencer guidance: if a reasonable person watching your content wouldn't otherwise realize it's paid, sponsored, or gifted, you're required to tell them, clearly, in a place they'll actually see it before they finish scrolling past.
