Review Signal Compounding

Review Signal Compounding treats review volume and recency as a compounding input to local search visibility rather than a vanity metric. Each new review adds a freshness signal and a keyword-rich snippet that feeds Google Business Profile ranking, which lifts map-pack impressions, which produces more customers who can leave the next review. The loop decays fast: a profile that collected 40 reviews in 2024 but nothing since loses recency weight while a competitor adding 6 per month overtakes it. For agencies, this reframes the retainer from reputation defense to a growth lever with a measurable cadence, and it gives a defensible reason to keep collection running through quiet months. Reviewly's SMS invitations, which the vendor reports at a 98% open rate, illustrate how the loop is fed at the point of service. The practical discipline is a monthly collection floor per client location, tracked alongside rank movement, not a one-off campaign.
