1. Maps is a GPS-first search engine — position is a function of location, not query
On google.com, if two people in Denver type the same query, they get almost the same results. Personalization is real but modest. On Maps, that same query from two people 800 feet apart returns different top-three results because Google is ranking by physical distance to the phone. Proximity is the single strongest ranking factor in the Maps algorithm, and it is applied at street-level granularity. A dental office one block off Main Street is winning searches from Main Street and losing them from three blocks east, where a competitor is closer to the searcher. This is why the 'one number per keyword' model fails. A tracker that pulls one Maps rank per keyword is either scanning from a fixed IP address (worthless — the result is the rank for that datacenter, not your customer) or averaging across cells you have no visibility into. SeoNexus scans from a grid of real GPS coordinates set to your storefront's actual latitude and longitude, radiating outward to the edge of your realistic service area. Every cell is an independent Maps search. You see the block-by-block picture that actually predicts whether a customer standing at a specific corner finds you. When we say we track Maps, we mean we simulate the Maps app at every point on the map that matters — not the query in aggregate, but the physical geometry of your competition.
