Google review gap calculator
Last updated: October 2026
Search your trade and town on Google Maps, then enter your review count and the top three results' counts. The calculator shows how far behind you are and roughly how many review requests a month it takes to catch up. It runs in your browser, and nothing you type is saved or sent.
Gap to the top-3 average (100): 80 reviews · gap to the leader: 130
To close it in 6 months: about 14 new reviews a month, or roughly 94 review requests a month at a 15% response rate.
If you ask every customer: 40 jobs a month at 15% is about 6 new reviews a month. Add your backlog of past customers to close it faster.
The response rate is an assumption you set, not a promise. Real rates vary by trade and customer. Look up your competitors' counts on Google Maps.
Why volume wins
Most strong local shops already have great ratings. The difference between them and the local leader is usually how many customers were actually asked. ReviewAsk asks every customer after each finished Jobber or Housecall Pro job, plus one follow-up on day 3, for $39/month. Email requests work today, and SMS is rolling out.
