Use this when
competitor radius, nearby competitors, local competitor landscape, competitive density.
Process
Geocode the business address, then query OpenStreetMap's Overpass API for other businesses tagged with the same category within a defined radius (default a few kilometers, adjust to business density: tighter for urban, wider for rural). For each competitor found, capture name, address, phone, website, and distance from the target.
Sort by distance and present the competitive landscape: how many same-category competitors are within the radius, and where the target sits relative to them geographically. Calculate a rough competitive density (competitors per square kilometer) to contextualize how crowded the market is.
This is free, keyless public data (Overpass, Nominatim) — no account or API key required, and no live rank data. Be explicit that this maps physical proximity and listing presence, not search ranking: live geo-grid rank tracking (simulating searches from multiple points to see where the business actually ranks) requires a paid Maps/DataForSEO integration this team doesn't have. Never present a proximity map as if it were a rank map.
Report: competitor count within radius, a sorted list of the nearest competitors with available contact/web info, and competitive density. Recommend the paid-tier upgrade path only when the user asks for actual rank visibility, not as a default upsell.
