Why a 4.7-star rating with 80 reviews beats a perfect 5.0 with 12
September 22, 2026

A perfect 5.0 star rating sounds like the goal. It is not. Research from Northwestern University's Spiegel Research Center found that purchase likelihood typically peaks at ratings between 4.0 and 4.7 stars, then begins to drop as ratings approach a perfect 5.0. The reason is straightforward: nobody believes perfect.
When a potential customer sees a 5.0 rating with 11 reviews, their instinct is to question it. Are those reviews real? Are they from friends and family? Did the business delete the bad ones? The same research backs that up: ratings in the 4.7 to 5.0 range were less likely to lead to a purchase than ratings between 4.2 and 4.7.
A 4.7 with 80 reviews tells a completely different story. It says this business has done enough work that 80 real customers bothered to leave feedback. It says the business is not perfect, which is true of every business, but the overwhelming majority of customers had a good experience. That is believable. That is trustworthy. That converts.
The volume also matters for Google's local search. Google says that more reviews and positive ratings can help your business's local ranking, and that prominence is based partly on how many reviews you have. The three-pack, the map section at the top of local searches, is where that ranking shows up. A high rating on a handful of reviews has a hard time competing with a strong rating on a large, steady stream of them.
This is why suppressing bad reviews is not just against Google's policies. It is bad strategy. A negative review that you respond to professionally tells customers something important about how you run your business. It shows you are paying attention, that you take concerns seriously, and that you are the kind of company that makes things right when something goes wrong. That is a selling point.
The contractors with the strongest Google profiles are not the ones who never had a bad job. They are the ones who asked every customer for a review, responded to every piece of feedback, and let the volume of genuine positive experiences speak for itself. PorchPrompt helps you build that kind of profile one job at a time, automatically, without gaming anything.
