Trustpilot is where consumers argue about deliveries, and that is exactly why it is interesting for a service business. A platform built for high volume consumer complaints holds a company to a standard that a curated case study page never will: anybody can write, the company cannot remove what it dislikes, and the number on the profile moves.
Reading one for a business-to-business decision takes a small amount of care, because the score is not what most people assume, and the volume is not what most people expect.
A TrustScore is not the average of the stars on a profile. Trustpilot describes it as a weighted score that gives more weight to recent reviews and pulls a profile with few reviews towards the middle until there is enough evidence, so a young profile with three five star reviews will not show 5.0, and an old bad year fades as newer reviews arrive.
For a business service, judge content rather than volume. An agency has tens of clients a year, not thousands of orders, so read whether reviewers name the channel, the problem and the outcome, check that the reviews are spread across months rather than bunched in one fortnight, and read every negative review with the company's reply, noticing whether it answers the specific complaint.
Five minutes is enough: the latest five reviews, then all the negatives and replies, then the dates, then whether reviewers describe the service you are buying. What a profile can establish is that the company is real, has clients and handles complaints well; whether it can run your account is settled in a conversation with numbers in it.
The single most useful thing to know about a TrustScore is that it is not the arithmetic mean of the stars on the page. It is widely reported to be a weighted calculation that leans towards recent reviews and pulls a profile with few reviews towards the middle of the scale until enough of them exist to say anything. Trustpilot publishes the mechanics in its own help centre, and that is the place to read them rather than any summary, this one included: the article did not render for us on 21 September 2026, so everything in this section is reported rather than quoted.
Two consequences follow, and they hold whatever the exact arithmetic is. A young profile with three perfect reviews will not show a perfect score, which is a feature rather than a fault: it is the platform refusing to let three reviews mean as much as three hundred. And an old profile carrying a bad year from three years ago recovers as newer reviews arrive, so a score is a statement about the company now rather than a permanent record.
For a buyer this changes what the number is good for. Do not compare a 4.3 against a 4.6 as though they measured the same quantity of evidence. Look at how many reviews each is built on, and when they were written.
A reader judging a profile should know what the company can and cannot do to it, because that is what makes a review platform worth reading at all.
A business cannot delete a review. It can report one it believes breaks the platform's guidelines, such as a review not based on a genuine experience, one containing personal information, or one that is abusive. The platform's own team decides, and a review that is merely negative stays.
Invited and uninvited reviews. Reviews written after a company invited the customer through the platform's own invitation tools are labelled, so a reader can see how much of a profile came from invitations and how much arrived unprompted. A profile made almost entirely of invited reviews is not suspect, but it shows the company's ask more than the customers' impulse.
Warnings on profiles. Where the platform finds a company has tried to manipulate its reviews, it can place a visible warning on the profile. Few things tell a buyer more, and a reader should look for one before reading anything else.
What this means for the reader. The negative reviews still on a profile have survived the company's chance to report them, which makes them some of the most reliable lines on the page. Read them, and read how the company answered.
A retailer has one customer per order and can ask for a review the day the parcel arrives. An agency has perhaps twenty clients in a year, each of whom is busy, and no equivalent moment to ask. So a service business's Trustpilot profile is measured in tens where a retailer's is measured in thousands.
That makes volume the wrong test, and content the right one. Five reviews that describe the work in sentences, from named roles, across different months, tell you more than two hundred one-line ratings would. Read for whether the reviewer knows what they bought: somebody who names the channel, the problem and the outcome was actually a client.
It also makes the negative reviews unusually informative, because on a low volume profile nobody is hiding behind the average. Read them, read the company's replies, and notice whether the reply engages with the specific claim or recites a paragraph.
A service business has to ask for reviews, because satisfied clients rarely write one unprompted. How it asks decides whether the profile it builds is worth anything.
Ask everyone, at a natural moment. Review platforms' guidelines ask businesses to invite customers fairly rather than choosing only the happy ones. For a service, the natural moments are a milestone reached, a quarterly review, or the end of a project, and every client at that moment gets the same request.
Never pay for a review, or for a good one. In the United States, the Federal Trade Commission's rule on consumer reviews and testimonials, in force since October 2024, prohibits fake reviews and offering anything in return for a review on condition that it is positive, and the platforms' own rules go further. A discount for a five star review is exactly what the rule forbids.
No reviews from the inside. Staff, their families and partners writing reviews without saying who they are is the other thing the same rule names. A team that wants to help should ask clients, not write.
Keep it easy. One short email with the link, sent by the person the client works with, gets more reviews than a campaign. A reminder a week later is reasonable; a third is not.
A profile built this way grows slowly, and that slowness is part of why a reader can trust it.
No review anywhere will tell you whether an agency can run your account, because your account is not the one in the review. What a good profile establishes is that the company is real, that clients exist, that complaints are handled like an adult, and that nothing systematic is going wrong.
The rest is settled in a conversation with numbers in it. Ask what the first ninety days would do and how it would be measured. Ask which metric they would refuse to be judged on and why, which is a better question than it sounds: an agency that says
ACoS on its own understands what it is doing, because that metric can be made to look good by spending less and selling less.
And ask what happens when something breaks.
An account health problem does not wait for a monthly report, and the honest answer to that question is a process rather than a reassurance.
Sort by most recent and read the last five, whatever they say. Then read every negative review on the profile and each reply, which on a service profile is usually a short list. Then check the dates: a profile whose reviews all land in one fortnight had a campaign, and a campaign tells you about the marketing rather than the work. Then check whether the reviewers describe the service you are buying. Then stop, because the sixth minute adds nothing that a call will not settle faster.
For a buyer reading a service company's profile, the reply to a negative review often says more than the review. It is the one place the company shows, in public, how it behaves when something has gone wrong.
Reply once, in public, and promptly. A short answer within a few days shows the review was read. Silence reads as indifference, and a long exchange in public reads as an argument.
Be specific and say what changed. Acknowledge the problem in the client's terms, say what has been done about it, and say what the company does now so it does not happen again. A specific change is worth more to the next reader than any apology.
Protect the client's confidentiality. A service company knows a great deal about its clients' businesses. None of it belongs in a public reply, even when the review seems unfair. Correct a factual error plainly and offer to talk directly; leave the details out.
Do not argue the stars. Asking a reviewer to change a rating, in public or in private, rarely works and often appears in the next review. If the problem is genuinely solved, the client may update it themselves.
When reading another company's profile, judge its replies by the same test: specific, calm, discreet about the client, and clear about what changed.
Bring what the profile showed into the call. If a negative review names a problem, ask what changed afterwards and how the agency would know if it happened again; a specific answer is worth more than an apology.
Ask what the first ninety days would deliver and how it would be measured, and which number they would refuse to be judged on alone. For marketplace advertising, an agency that names ACoS understands the work, because ACoS can be improved simply by spending less and selling less.
Ask who would do the work day to day, how often you would see the numbers, and what happens out of hours when an account health warning or a suppressed listing appears. The good answer to the last question is a process with a named owner, not a promise.
And ask for a client you can speak to whose account looked like yours. A review is one client's view at one moment; a conversation lets you ask about the parts a review leaves out, such as how the agency behaved when results dipped.
