Estimate based on common industry patterns. Not a guarantee.

What this means

At this level, no-shows are often costing the equivalent of one full day of revenue each month — sometimes without anyone realizing it. The goal is to make the cost visible so you can prioritize what to fix first.

Formula

Monthly revenue loss = New customers/month × Star-drop impact × Avg ticket

Assumptions

  • Conversion impact assumed at 6% for the selected star-drop scenario.
  • Impact model: ~12% conversion impact per full-star drop, calibrated to Harvard Business School (Anderson & Magruder 2012) + subsequent BrightLocal/ReviewTrackers ranges.
  • Gross margin assumed at 60%.

Tips

  • Respond to reviews consistently to stabilize trust.
  • Follow up with unhappy customers privately before issues spread.
  • Track rating changes alongside new customer volume.

Local SEO impact (plain-language)

Ratings influence how often people click your listing. A small drop can reduce clicks even if your services stay the same.

Why responses help even without rating changes

Replying quickly shows accountability, which can soften the impact of a lower rating and improve conversion.

How this was calculated

Methodology v2026.01.1. These estimates are directional and depend on inputs and assumptions.

  • Monthly new customers × rating change impact.
  • Average ticket converts customer impact into revenue.
  • Gross margin optional for profit impact.
  • Ranges reflect conservative conversion shifts.

FAQ

Does this assume a direct rating-to-revenue link?

It models an indirect conversion impact and keeps assumptions conservative.

Are these estimates exact?

No. They are directional so you can see the size of the leak before refining assumptions.

Can I change the assumptions?

Yes. Adjust the inputs to reflect your business and rerun the numbers.

Why use a range instead of a single number?

Ranges reflect uncertainty and help you stress-test best and worst cases.

Does this include profit?

Use the gross margin input to translate revenue impact into profit impact.
