The Short Answer
Client reviews are one of the strongest prominence signals feeding into Google Maps 3-pack ranking, and they're often the single factor a prospective client weighs most heavily before ever calling a firm. Both review volume and average rating matter, but recency and response rate matter almost as much — a profile with 40 reviews from three years ago and none since reads very differently to both Google and a searcher than one with steady, recent activity.
What Actually Moves the Needle
Volume matters, but not in isolation — a firm with 15 recent, detailed, genuine reviews often outperforms one with 60 old, generic ones. Google's systems weigh recency, and prospective clients scanning reviews specifically look for detail and specificity, since vague five-star reviews with no substance read as less trustworthy than a review that actually describes the experience.
Response rate is the most consistently overlooked lever. A firm that thoughtfully responds to every review — thanking positive ones, addressing negative ones professionally — signals active, engaged management, which is itself a trust and prominence factor Google and prospective clients both notice.
Building Reviews the Compliant Way
The Law Society of Alberta doesn't prohibit asking for reviews, but the process has to stay within the same advertising rules that govern everything else client-facing — no incentivizing reviews with anything of value, no soliciting only from clients with favorable outcomes while ignoring others, and no review content the firm writes or edits on a client's behalf.
A simple, consistent ask — built into the intake or closing process rather than a one-off campaign — steadily builds a review base that reads as genuine, which matters more for both compliance and actual persuasiveness than a review-generation push done all at once. See how this fits into the broader Google Business Profile picture.
A steady trickle of genuine, recent reviews beats a burst of forty reviews in one week that then goes quiet for two years. Google notices the pattern, and so do prospective clients scrolling through the dates.
