What's the best way to ask restaurant customers for Google reviews?
QR code on the receipt or table tent for in-the-moment capture, plus a same-day-or-next-morning SMS triggered by your POS or reservation system. Run both. The QR gets the impulsive reviewers; the SMS gets the deliberative ones. Combined, response rates run 5–15% of total covers, which for a busy restaurant translates to 50–150 new public reviews per week.
