Direct Answer
Request reviews 7 to 10 days after purchase — response rates peak at 18 to 22% at days 7 to 8, versus 8 to 10% on day 3 and single digits by day 30. Exception: restaurants, salons, and home service providers should request within 24 hours, while the satisfaction peak is still active. For timing, send SMS between 2 and 5pm, then follow with email Tuesday to Thursday at 10am to noon for non-responders. The two-channel sequence consistently delivers 2 to 3x more reviews than a single-channel or same-day request.
RelinkAI is a review management platform that helps local businesses intercept negative reviews before they go public, automate 5-star review collection, and recover their Google rating.
The timing of a review request matters more than the message itself. A well-written request sent at the wrong moment gets ignored. The same request sent at peak satisfaction gets a response.
The Timing Window: Why 7 to 10 Days Beats Immediate or Late
Kudo Buzz’s review response study shows a clear performance curve by day: response rates peak at 18 to 22 percent around days 7 to 8, compared to 8 to 10 percent on day 3. By day 30, rates drop back to single digits. The 7-to-10-day window is not a guideline; it is a data-backed inflection point.
The psychological mechanism behind this is the peak-end rule: customers form lasting judgments of an experience based on its most emotionally intense moment and how it ended. A review request that arrives while that emotional memory is still active catches the customer at a moment of cognitive readiness. Requests that arrive same-day, before the customer has formed a settled impression, generate vague reviews and low completion. Requests that arrive 30 days later compete with dozens of other experiences and arrive after the emotional charge has dissipated.
The exception to the 7-to-10-day rule is immediate-service businesses. A restaurant, salon, or home service provider should request reviews much sooner, because the “product” was experienced in full and the satisfaction peak occurs at or immediately after the appointment ends. For these categories, the window is hours, not days.
Day of Week and Time of Day: The Double Optimization
Timing is not just about the post-purchase window. The day of week and time of day compound the effect. Expert Reputation’s review request best practices research identifies Tuesday through Thursday at 10am to noon as the peak email window, with 75 percent of email opens occurring between 9am and 11am. Mondays suffer from inbox overload. Fridays suffer from the mental shift toward the weekend.
SMS operates on a different rhythm. According to Expert Reputation’s research, the peak SMS response window is 2 to 5pm, with response rates 3 to 4 times higher than morning or evening sends and SMS open rates exceeding 98 percent. The reasoning is straightforward: customers are past the busy morning but not yet disengaged from the workday. They have their phone in hand and are more likely to act on a short request than they would be at 8am or 9pm.
Kudo Buzz’s research also shows response rates drop sharply after 7pm for both channels. A review request that lands at 8pm competes with social media, family time, and the mental winding-down of the day. The same request at 2pm competes with much less.

Business-Type Timing: Matching the Request to the Experience
Timing varies by how quickly customers can evaluate the experience. A restaurant meal is judged in real time; a software subscription takes weeks to assess properly.
According to Digital Harvest & Local Impact research, timing windows shift by industry:
For restaurants, bars, and hospitality, the optimal window is within 24 hours, ideally 1 to 2 hours after the visit. The emotional peak is at its highest, the meal is still the most recent thing they ate, and the request arrives before the next day’s experiences crowd it out.
For personal services like salons, repair shops, and cleaning services, the request should go out same-day, immediately after the service ends. The transformation is visible and immediate. Waiting 7 days lets the haircut grow out a bit and dilutes the satisfaction peak.
For home services and contractors, the moment of job completion is the request window. The technician leaving a well-done job is the satisfaction peak. A follow-up request 24 hours later as a backup is appropriate if the immediate moment was missed.
For product-based businesses, how to ask for Google reviews without spamming covers the sequencing in more detail. The 7-to-10-day rule applies most cleanly here: the customer has received, unboxed, and used the item, and has formed a settled opinion. Asking before this point generates either non-responses or unhelpfully vague reviews.

Frequently Asked Questions
Should I ask for a review immediately after the service, or wait?
It depends on the business type. For restaurants, salons, and personal services, ask within 24 hours while the emotion is fresh. For products and longer-term services, wait 7 to 10 days so the customer has had time to use and evaluate the item. Research shows response rates of 18 to 22 percent at days 7 to 8 versus 8 to 10 percent on day 3 for product-based requests.
What is the best day of the week to send a review request?
Tuesday or Wednesday. By Tuesday, customers have cleared Monday’s overloaded inbox and are actively engaging with messages. Avoid Monday, when inbox congestion is highest, and Friday, when the weekend mindset reduces response rates.
Should I use SMS or email for review requests?
Both, in sequence. Send SMS at 2 to 5pm for the highest engagement window, then follow with email 24 to 48 hours later for non-responders. The combined sequence captures customers across their different communication preferences and moments of readiness.
Does the customer's time zone affect timing?
Yes, always send based on the customer’s local time. A 2pm send in your timezone lands at 8pm for a customer three time zones away, dropping into the low-response evening window. Time-zone-aware automation is essential for any business with customers across multiple regions.
What if I missed the optimal window and it has been 30 days?
Send anyway, but keep expectations calibrated. Day-30 response rates drop to single digits compared to the 18 to 22 percent peak at days 7 to 8. Going forward, set up automation that triggers within the right window for each transaction rather than relying on manual campaigns that inevitably run late.
