The Short Answer
Reviews are one of the strongest prominence signals in local SEO, directly affecting Google Maps 3-pack ranking and giving a prospective client the social proof they're actively looking for before choosing a lawyer. A firm with 5 recent, detailed reviews consistently outperforms an otherwise-similar firm with none, or with reviews that are years old.
Quality and Recency Matter as Much as Volume
A steady, ongoing flow of recent reviews signals an active, currently-trusted practice far more than a large batch from years ago followed by silence.
Detailed reviews mentioning specific practice areas or outcomes — without breaching client confidentiality — also help relevance signals, since they reinforce which services the firm is actually known for.
Building an Ethical, Consistent Review Process
The most effective approach is simple and repeatable: ask satisfied clients for a review at the natural close of their matter, make it as easy as possible with a direct link, and never offer any incentive in exchange for one — which violates both Google's policies and Law Society of Ontario advertising rules.
