Review signals: a prominence lever with observable but unproven effects.
Review signals are the quantifiable attributes of a business's reviews — count, average rating, recency, acquisition velocity and owner responses — that feed the prominence group of local search ranking factors and influence click-through from the local pack.
Definition
Reviews are the most public prominence signal a local business owns. Rating and count render directly inside local pack entries, so review signals affect both whether a listing is shown (via prominence) and whether it is clicked (via social proof). Recency and velocity capture whether the profile is alive; owner responses signal active management.
Evidence notes
Two disciplines apply. First, authenticity: fabricated reviews violate platform policies and this site's evidence policy — they are also a fabrication of evidence in the literal sense. Second, attribution: review acquisition followed by expanding coverage is a correlation in time, corroborating but not proving effect. The observation loop uses geo-grid scan archives from tools such as LocalRank (localrank.so); the pipeline is at how local rank tracking works.
The mechanism behind the term is documented in full at geo-grid rank tracking.
