How star ratings and review counts affect bookings

What the research actually measures

Owners often hear confident claims like 'every extra star adds X% to revenue'. Most of those numbers come from studies of restaurants or online retail, not of plumbers, roofers or house cleaners, and many come from vendors who sell review software. It is worth separating what is well established from what is a reasonable guess for home services.

Two well-known sources are useful. Pew Research Center surveys tell us how Americans use reviews in general. The Spiegel Research Center at Northwestern University analyzed how reviews relate to purchases, using data from online retailers. Neither studies home services directly, so treat them as a guide to how people read reviews rather than a forecast for your booking rate.

How many people read reviews

Pew found that 82% of US adults at least sometimes read online ratings or reviews before buying something for the first time, and 40% always or almost always do^[1]. Younger adults rely on them most: 53% of 18- to 29-year-olds and 47% of 30- to 49-year-olds always or almost always read reviews before buying something new^[1].

Trust is mixed. About half of review readers (51%) say reviews generally give an accurate picture, while 48% say it is often hard to tell whether reviews are truthful and unbiased^[1]. In other words, most people read reviews and many read them skeptically. They look for signals that the reviews are real.

For home services, the stakes of choosing wrong are high and the choice is often rushed. In Angi's 2025 survey, 53% of homeowners on average reported difficulty finding pros^[3]. When it is hard to find someone at all, the few listings that look established and trustworthy get the call.

What the Spiegel research found

The Spiegel Research Center reported that a product with five reviews had a purchase likelihood 270% greater than a product with no reviews^[2]. The effect was larger for more expensive items: conversion rose 380% for a higher-priced product versus 190% for a lower-priced one^[2].

Two findings are especially relevant to contractors. First, the jump from zero to a handful of reviews matters most, which means a new business or a new location should prioritize getting its first real reviews. Second, purchase likelihood typically peaked at ratings in the 4.0 to 4.7 range and then declined as ratings approached 5.0^[2]. A perfect score can look too good to be true.

The study also found that verified buyer badges improved the odds of purchase by 15%^[2]. Google reviews do not carry such badges, which is one reason specific, detailed reviews and real photos carry weight: they are the closest thing a reader has to proof that the reviewer was a customer.

What probably matters for a home service listing

Putting the research together with how people choose contractors, these are the signals worth managing. They are practical judgments, not measured effects.

How homeowners tend to read a contractor's reviews

Watch a homeowner choose a contractor on a phone and a pattern appears. They glance at the rating and count in the map results, open two or three listings, scroll the newest reviews, and then look for the one-star reviews to see what went wrong and how the business answered. The whole process can take less than two minutes when something is broken.

• They read the newest reviews first, because they want to know what the company is like now.
• They look for their own situation: an emergency at night, an older home, a rental, a specific brand of equipment.
• They read the worst reviews deliberately, to judge whether problems are rare and handled well.
• They notice technician names that appear again and again, which suggests a stable team.
• They dismiss vague praise and reviews that sound alike, which is why honest, varied reviews beat a pile of generic ones.

None of this needs a study to act on. It tells you to keep reviews recent, to reply to complaints with care, and to make it easy for customers to mention the specifics of the job when they write.

Common myths about ratings

• 'One bad review will sink us.' In a profile with steady volume, a single complaint with a calm reply rarely decides a booking, and it can make the praise more credible.
• 'We need to remove every negative review.' Only reviews that break platform policy can be removed. The rest are managed through replies and better service.
• 'Review count is all that matters.' A large count of old reviews says little about current service. Recency matters.
• 'Asking for reviews will annoy customers.' A short, polite request once or twice is normal. What annoys people is repeated pressure or offers that feel like bribes.
• 'Our rating explains our slow month.' Check answer rate, speed and availability before blaming reviews.

Example: two listings side by side

Example: a homeowner with a dead furnace compares two fictional HVAC companies on a map at 7 a.m.

• Company A: 5.0 stars, 11 reviews, the newest from 14 months ago, no owner replies, stock photos.
• Company B: 4.6 stars, 240 reviews, five from this week, replies to every review including two recent complaints, photos of branded vans and technicians.

Most people call Company B, even though its average is lower. The volume and recency show it is busy and real, the replies show it is accountable, and the two complaints with calm replies make the praise more believable. Company A's perfect score is not what loses the call; the silence around it is.

Where to focus based on your profile

1. 01

   Fewer than 20 reviews

   Focus entirely on volume. Ask every customer, in person and by text, with a direct link. See how to get more Google reviews.

2. 02

   Rating below 4.0

   Look for patterns in complaints before asking harder for reviews. Fix the operational cause, reply to every negative review and let new reviews reflect the change.

3. 03

   Rating 4.0 to 4.7 with steady volume

   Maintain the flow and improve replies and photos. You are in the range the research associates with the strongest purchase likelihood.

4. 04

   Rating near 5.0 with low volume

   Prioritize volume and recency. A few honest four-star reviews will not hurt you.

5. 05

   Strong profile, slow bookings

   Look elsewhere: answer rate, response speed, availability and price clarity. Reviews get the call; the phone call gets the booking.

Reviews start the booking, the phone finishes it

A strong profile earns attention, but a homeowner who calls and reaches voicemail moves on to the next listing. Track how many calls come from your profile and how many of those become booked jobs. If profile views rise and bookings do not, the gap is usually in answering and booking, not in the reviews. Covering every call is also where an AI employee such as Ava can help, answering when the office is busy and booking the visit.

Finally, read your reviews for what they teach, not just for the number. Complaints about arrival windows, price surprises or messy work are free consulting. For tools to act on that feedback, see mapping the customer journey for a service call and Net Promoter Score and post-job surveys.
