Everything on this site in one connected picture: what Maps data is, the five-stage system that turns it into pipeline, and the deep guide for each stage. Start here, branch where your situation demands.

Why Maps, and why not
Google Maps holds a listing for effectively every discoverable local business: name, phone, website, address, coordinates, category, hours, rating, review count. For anyone selling to local businesses, that is the market census, fresher than any purchasable database and segmentable in ways none of them offer. The honest limits: no named decision-makers, no emails on the listing itself (discovery runs 20-40% via linked websites), and no coverage of businesses without physical presence. Right source, specific shape.
Stage 1: extract completely
A single search returns roughly 120 results however large the city, so real coverage means grid extraction: subdivide, sweep, merge. Tooling is a three-way choice (extension, cloud, desktop flat-licence) decided by volume and refresh frequency, with free routes covering small jobs and the extraction guide covering technique, including building your own and the official API's place in it.
Stage 2: clean on the right keys
Raw exports carry designed-in duplication and real-world rot. The sequence: de-duplicate on place ID, filter permanently-closed listings, drop uncontactable rows, normalise phones to E.164, stamp the extraction date. Expect to lose 10-20% of rows, which is the cleaning working. Field-by-field trustworthiness lives in the data-quality guide; spreadsheet mechanics in the Excel and Sheets guides.
Stage 3: segment before anyone dials
Three cuts carry most of the value: review-count bands (the best free qualification signal local data has), website presence (routes rows between email and phone work), and geography by coordinates for coherent territories. The workflow guide adds the discipline that makes segments convert: rationed release, one to two hundred rows at a time.
Stage 4: outreach that fits category and market
Channel is a category question first (trades answer mobiles, clinics answer front desks, professionals read email; the 50 industry and audience guides carry per-niche notes) and a legal question second (the legality guide for the frame, the country pages for US, UK, India, Canada, Australia and Germany specifics). The message itself should use the data visibly; the strategies guide details the five plays, review-gap prospecting first among them.
Stage 5: refresh, and mine the difference
Lists decay at roughly 1-2% a month; quarterly re-extraction resets the clock, and the diff between pulls is its own product: new listings are businesses in buying mode, disappeared IDs are the do-not-dial list, review-count jumps flag businesses investing right now. This compounding loop is what a Maps-built pipeline has that no purchased list can, and it costs minutes under a flat licence.
