NPS Surveys vs Google Reviews: Which Should You Run?

Net Promoter Score asks one question — how likely are you to recommend us — on a nought-to-ten scale, and sorts respondents into promoters, passives and detractors. It is a well-established internal measure.

A Google review is a public statement attached to the listing customers find when they search for you.

Both involve asking a customer what they thought, which is why they get conflated. They serve entirely different purposes.

What each is actually for

NPS tells you something. It is a diagnostic instrument: a trend line, segmented by location or service or team, that tells you whether you are improving. Its value is internal and it is mostly about the comparison over time rather than the absolute number.

Google reviews tell everyone else something. They are the thing a prospective customer reads at the moment of deciding, and they feed local ranking. Their value is external.

A perfect NPS score wins you no customers if nobody outside the company can see it. A strong Google rating wins customers while telling you relatively little about why.

The trap: using NPS to filter

This is the pattern worth being blunt about, because it is widely sold as best practice and it breaches Google's policy.

It goes: survey the customer first, and route the nines and tens to your Google review link while sending everyone else to a private feedback form. It sounds reasonable — why advertise your unhappy customers?

That is review gating. Google's policy prohibits selectively soliciting reviews from customers based on expected sentiment, and the penalty can include removal of reviews collected that way.

The legitimate version: ask everyone for a public review, and separately offer everyone a private channel to raise problems. The private channel is genuinely valuable — it catches issues before they become reviews — but it must be offered to all customers, not used as a diversion for the ones likely to complain.

Which to run first

For most small and medium local businesses, public reviews come first, and it is not a close call. If you have thirty reviews and a competitor has three hundred, your constraint is visibility, not measurement. An NPS programme will produce a number you are not currently able to act on better than your reviews already tell you.

NPS starts earning its keep when:

• You have multiple locations or teams and need to compare them fairly
• Volume is high enough for the trend to mean something
• You have someone whose job includes acting on the result
• You want structured data on specific aspects rather than whatever reviewers chose to mention

Read your reviews as research

Before investing in a survey programme, note that your reviews are already a dataset. Recurring complaints are your lowest-hanging operational fixes, and they came free, with the names of the people affected.

Running both

If you do run both, keep them separate. One message asking for a public review. A different, clearly internal survey for measurement. Combining them produces a confusing experience and drags you toward the gating problem.
