Do Google Reviews Help Local SEO?
Yes. Reviews are a clear local-search signal: the number of reviews, your average rating, how recent they are, and even the words customers use all feed into local rankings and the map pack.
They also lift click-through, a profile with lots of recent, high reviews earns more clicks than a competitor with fewer. Reviews are one of the few ranking factors you can honestly influence.
Caveat: they are not the only factor, proximity, categories and profile completeness matter too. But among things in your control, steady genuine reviews are high-leverage.
