You spent six months building up 40 Google reviews. You're ranked well locally. Then you get busy, stop asking for reviews, and three months later your ranking quietly drops. You didn't lose any reviews. You didn't get a bad one. Your reviews just got old. Here's why that matters more than most tradespeople realise.
The number that changes everything
Most tradespeople think of their Google review count as a number that only goes up. You get a review, it stays forever, it keeps working for you. That's not how Google sees it.
Nearly three quarters of your potential customers are only reading your most recent reviews. The 35 reviews you collected last year are still visible on your profile — but from a trust and ranking perspective, they're doing a fraction of the work they once were.
Google isn't just counting how many reviews you have. It's asking: when did this business last satisfy a customer? A review from 14 months ago doesn't answer that question convincingly. A review from last Tuesday does.
"A business with 25 recent reviews can outrank a competitor with 75 old ones. Recency beats quantity every time."
How reviews age — and when they stop pulling their weight
Reviews don't expire in a hard sense — they don't disappear and they don't stop counting toward your total. What changes is how much weight Google's algorithm assigns them and how much trust customers give them when they read your profile.
Full weight — peak trust
Maximum ranking signal. Customers who read your profile see this first. Google treats your business as currently active and trusted. This is the window where reviews do their best work.
Reduced weight — fading trust
Still contributing to your total and your rating, but the recency signal is weakening. Customers increasingly skip these and look for something more current. Ranking benefit starting to decline.
Minimal recency signal — stale
69% of consumers consider these outdated. They still count toward your star rating but they're no longer telling Google you're actively serving customers. A competitor getting fresh reviews is pulling ahead.
What happens to your ranking when reviews go stale
This is the part that surprises most tradespeople. Research from Sterling Sky found that rankings can drop noticeably when businesses stop receiving reviews — in some cases within just three weeks of review inactivity. Whitespark's 2026 local ranking factor analysis confirms that review recency has become one of the most underrated local ranking signals.
The reason makes sense when you think about what Google is trying to do. Google wants to recommend businesses that are currently active and currently satisfying customers. A plumber who got 40 great reviews in 2024 and nothing since tells Google one of three things — the business got quieter, the quality dropped, or something changed. None of those are signals that inspire confidence.
Meanwhile, a competitor who has been getting 2–3 reviews per month consistently is telling Google something very different: this business is active, customers are happy right now, and it's a safe recommendation today.
42 total reviews — all from 2024
4.8 star average
Last review: 5 months ago
No recent activity signal
Ranking slowly declining
28 total reviews — mostly recent
4.7 star average
Last review: 4 days ago
Strong recency signal to Google
Ranking improving every month
Plumber B has fewer reviews and a slightly lower rating — but wins on recency. Google rewards the business that's demonstrably active right now, not the biggest historical number.
The 18-day rule worth knowing
Research into review recency and ranking identified what some local SEO practitioners call the 18-day rule — rankings can start to weaken if a business goes more than two to three weeks without a new review. This isn't a hard Google policy, but it reflects a consistent pattern observed across multiple businesses and industries.
For a solo plumber doing 20 jobs a week, going 18 days without a new review should be impossible if they're asking for one after every job. But for a tradesperson who only asks occasionally — or doesn't ask at all — that gap can stretch to months without them noticing. And by the time the ranking drop becomes visible in fewer inbound calls, the problem has been building for weeks.
"You don't lose rankings overnight. You lose them gradually, quietly — every week that passes without a fresh review telling Google you're still the right answer."
The fix is simpler than it sounds
Maintaining review recency isn't about a campaign or a one-time push. It's about making review collection a consistent part of every completed job — so that reviews arrive in a steady flow rather than in bursts followed by silence.
Ask after every single job — not occasionally
The only way to maintain recency is consistent collection. A review request sent after every completed job means Google always has something recent to work with.
Timing matters — ask within hours, not days
Customers are most likely to leave a review when the job is fresh in their mind and their satisfaction is at its peak. A request sent 3 days later converts at a fraction of the rate of one sent right after completion.
Make it one tap — not a search
A direct link to your Google review page eliminates the friction of finding your profile. The easier it is, the higher the response rate, the more consistent your review flow.
Don't do a one-time blast
Asking all your old customers for reviews at once generates a spike that looks unnatural and fades quickly. Steady beats sudden every time — for both Google's algorithm and customer trust.
In CashWrench, the review request goes out the moment you mark a job complete. Every job. Every time — so your review flow always gives Google something recent to factor into your ranking.
Your older reviews don't disappear. They still contribute to your overall rating and your total count. But the ranking and trust work is done by the fresh ones. Keep them coming and your profile stays competitive. Let them go stale and a competitor with fewer total reviews but better recency will quietly pass you in the local results.
