Google Maps scraper: how Lead Finder extracts business listings

What is a Google Maps scraper?

Lead Finder is a Google Maps scraper: software that collects publicly published business listings from Google Maps and writes them to a spreadsheet. A scraper reads what the map already shows, business name, phone number, address, coordinates, website, category, rating and review count, and converts it into rows. Three delivery models exist and they fail in different places: browser extensions read what the page has loaded, cloud platforms run on someone else infrastructure and bill per row, and desktop applications run on your machine under a flat licence. One constraint binds all three equally. A single Google Maps search returns roughly 120 results regardless of how many businesses exist, because the ceiling applies per query rather than per city, so complete coverage requires grid extraction whichever model you pick.

The three delivery models

A browser extension runs inside Chrome and reads the listings the page has already rendered. It installs in seconds, usually costs nothing, and suits lists of a few dozen rows. Its ceiling is structural: it cannot see past what the interface loaded, so whole-city coverage is out of reach.

A cloud platform executes the job on the provider infrastructure, can run on a schedule and can be called by another system. It is the only model that works unattended. Billing follows volume, so thoroughness and cost rise together, which matters most precisely when you want the complete picture.

A desktop application runs on your own machine under a flat annual licence. Cost does not move with row count, which makes exhaustive coverage free in the only sense that matters to a budget. The trade is that the machine must stay on during long runs and nothing can call it programmatically.

What every scraper hits

The 120-result ceiling is not a limitation any particular tool imposes, and no tool removes it. It applies to the query, so a city with four thousand restaurants still returns roughly 120 for a single search, and the list gives no indication that it is truncated.

Grid extraction is the only workaround that exists. The target area is divided into smaller cells, each cell is searched as its own query, and the results are merged with duplicates removed on place ID because the same business commonly appears in neighbouring cells. Desktop and cloud tools implement this; extensions generally cannot.
