The review math: why 4.6 stars is the actual target

The counterintuitive truth of restaurant reviews: perfect scores hurt you.

**The 4.6 sweet spot.** Northwestern's Spiegel Research Center found conversion peaks between 4.2 and 4.6 stars. Above 4.7, buyers get suspicious — it looks too clean, like fake reviews. Below 4.2, the negatives start scaring people off.

**Volume matters more than average.** A 4.5 with 400 reviews beats a 4.9 with 22. Volume signals "many people have tried this and mostly liked it." Sparse-and-perfect signals "the owner's friends left reviews."

**Freshness matters more than volume.** Google's local algorithm weights recent reviews harder. A single review from last week is worth 3 from 2022. If your last review is 4 months old, you're not just stagnant in ranking — you look closed.

**The operator playbook:** 1. **Ask every table.** Bottom of the receipt. QR code on the check presenter. Physical card. Get 30-day post-visit texts firing. 2. **Respond to every review** — 5-star and 1-star. Google reads the response rate. Prospective diners read the responses. 3. **Never buy reviews.** Google catches this. It's a permanent listings-suspension risk. 4. **Aim for 4–6 new reviews per week.** That's the floor for a restaurant doing 40+ tables a day. Below that and you're losing to competitors who are asking harder.

Getting to 4.6 from 4.2 is worth roughly 15% more clicks from search. On a busy restaurant, that's easily $40k+/year in incremental revenue.
