How to Use Google Review Data to Find Your Best Prospects — Margo field notes

Review Data as a Prospecting Signal

Most salespeople ignore review data. That's a mistake. A business's Google review score and review count tells you a lot about their situation — and how likely they are to need what you're selling.

Decoding Review Scores

ScoreWhat It SignalsOutreach Opportunity
4.5–5.0Established, confidentPremium offers, growth tools
3.5–4.4Growing, room to improveReputation management, marketing
2.5–3.4Struggling, likely frustratedOperational tools, quick wins
Under 2.5Crisis modeAvoid unless you solve reputation directly

Review Count as a Size Proxy

Review count correlates with customer volume. A restaurant with 800 reviews is doing much more business than one with 20. Use this to estimate business size without needing revenue data.

Using Review Recency

Recent reviews indicate an active business. Businesses with their last review from 18 months ago may be declining or closed — worth filtering out.

Building Segments Around Review Data

With Margo, you can filter leads by review score. A few high-value segments to build:

  • "Ready to grow" list: 4.0–4.5 stars, 100+ reviews, has a website
  • "Needs help" list: 3.0–3.9 stars, any review count, no clear marketing presence
  • "Established" list: 4.5+ stars, 200+ reviews — for premium-tier offers

Conclusion

Review data is free, publicly available, and deeply informative. Use it as a prospecting signal and you'll build sharper lists with fewer wasted touches.
