Google Maps sourcing

Where the listings come from

Public Google Maps business listings, read during your order against the business categories and locations you specified. One order can cover several categories and several places at once; the 2026-07-23 build below ran two metros in a single order.

We do not use the official Places API. Its terms prohibit reselling the data, and a product built on a licence it violates is not a product. Working from public listings is the decision that lets us sell you the file.

On 2026-07-23 we built a 20-lead HVAC contractor list in Phoenix, AZ and Dallas, TX with a 50+ Google review bar, and delivered 20 of 20, finishing in 108 seconds.

How a category search actually behaves

Category matching is approximate, not a database join. Asking for one trade will sometimes return an adjacent one, because Maps itself treats them as neighbours. This is the single most common surprise in a delivered file.

The mitigation is wording: specific category language returns tighter results than broad trade terms. Several categories in one order is usually better than one vague one.

• Google Maps category matching is approximate. In the 2026-07-23 HVAC build, a roofing company appeared in the results for an HVAC search because Maps treats the two as adjacent trades. Broad trade searches are the most affected; specific category wording is the mitigation. Observed 2026-07-23.

What “fresh” means precisely

Two different things, both true at build time. The listing data is as current as Google Maps was when we read it during your order. The email address was verified in the same run, minutes before delivery.

Neither claim is about our database being better maintained than someone else's, because we do not keep one. There is nothing stored to go stale between your order and your file.

What can go wrong

• A business with no website almost never yields a verifiable email, because the address is discovered by reading the business's own site. Categories and countries where businesses operate from a social page alone will fill more slowly, or not to the full quantity. Observed 2026-07-27.
• Every run recorded above is US. Orders outside the US are accepted and the engine is not US-specific, but we have no measured fill rate for them yet, and we will say so rather than imply otherwise. In markets where small businesses commonly have no website, expect a lower fill rate and set the review bar lower. Observed 2026-07-27.

Questions

Can one order cover several cities?

Yes. Up to twenty locations per order, and any place Google Maps resolves — a city, a state, a country.

Why did a business from a different industry appear in my file?

Google Maps treats some categories as adjacent and returns them for each other. More specific category wording narrows it.

Do you keep the data after delivery?

The delivered file is retained for thirty days so you can re-download it. A CRM export you upload for deduplication is deleted as soon as the order is fulfilled.
