Why reputation is now the main local ranking factor
For a local business, the search result page is the storefront. Google's local pack ranks on relevance, distance and prominence, and prominence is largely built from reviews: how many you have, how recent they are, how highly they score and how consistently you respond. That means reputation is not a branding exercise that sits next to marketing - it is the input that decides whether you appear in the three-result map pack for the searches that actually generate calls. Two contractors a mile apart with identical services will see wildly different call volume purely because one has 240 recent reviews averaging 4.8 and the other has 31 reviews averaging 4.2 with nothing new in a year. Reputation compounds: the businesses that rank get more customers, who leave more reviews, which entrenches the ranking.
