The short answer: there is no fixed number of reviews you "need," but the rule that matters is simple — you should have more recent, higher-rated reviews than the competitors ranking above you, and you should keep a steady flow coming in. Volume, rating, recency, and your responses all count.
It is relative, not absolute
If the top plumber in your city has 80 reviews and you have 15, you are behind — regardless of the raw number. Look at who ranks in your local top three and aim to beat their review profile.
Rating threshold matters for AI and Google
Both Google's local ranking and AI search tools favor businesses at roughly 4.3 stars and above. A high volume of reviews with a mediocre average can actually hurt you.
Recency beats a big old pile
A steady trickle of new reviews signals an active, trusted business. Ten reviews in the last month can outweigh fifty from three years ago. Consistency is the goal.
Respond to every review
Responding — to positive and negative alike — is itself a ranking and trust signal. It shows Google and customers that you are engaged.
The simplest system that works
Ask for a review right after the job is done, while satisfaction is highest, and send a direct link so it takes one tap. Automating this request is the single highest-ROI thing most home-service businesses can do.
