What are reviews actually worth?

The ROI calculator on this page estimates the revenue impact of collecting more Google reviews for a local business. It works from three published effects, each of which ReviewNudge is built to move.

Higher star rating

A one-star increase on Google is associated with a 5–9% revenue lift, per Harvard Business School research. ReviewNudge routes happy customers to Google and catches unhappy ones privately, which lifts the average rating that prospective customers see.

Complaint firewall

91% of unhappy customers who do not complain simply leave, and 72% switch after a single bad experience. Intercepting a complaint before it reaches Google protects the revenue attached to that customer and gives you a chance to put it right.

Referral engine

After a 5-star review, ReviewNudge asks "know someone who'd love us?". Referred customers show roughly 37% higher retention and 16% higher lifetime value than customers acquired through other channels.

Fresh reviews are an SEO signal

Review volume and recency both feed Google's local pack ranking. A business collecting a steady stream of new reviews outranks one with an older, larger pile, which is why a monthly cadence matters more than a one-off push.

What the calculator asks for

Your monthly customer count, your average transaction value, your current Google rating and your current review count. It returns a projected monthly and annual figure. The numbers are an estimate built from the research above applied to your inputs — not a promise, and not a measurement of your business.
