Why Spain
A deep, fragmented local market
Spain is a lead generation goldmine because its economy is built on small and medium businesses. The national statistics office (INE) tracks millions of active companies through its Central Business Register, and most of them are local operators: restaurants, clinics, workshops, agencies and shops. You can browse the underlying data at the Instituto Nacional de Estadistica.
Almost every one of those businesses has a Google Maps profile with a phone number, an address and often a website. That makes Maps the single largest, freshest directory of Spanish local businesses, and it updates itself as owners edit their listings.
The problem is not finding the data. It is getting it out of Maps and into a usable list without copying rows by hand. That is exactly what a browser extension solves.

The workflow
From a Maps search to a lead list in four steps
The mechanics are simple. You do not need the Google Places API, a developer key or a Python script. You need Chrome, the Vonsel extension and a search query.
1. Search by niche and city. Open Google Maps and type something like peluquerias en Valencia or clinicas dentales Madrid. Use the Spanish term the way locals search, so Maps returns the deepest set of results.
2. Let the extension capture. As you scroll the results panel, the Vonsel pop-up captures each listing: business name, phone, address, category, rating and website. For a full walkthrough see how to scrape Google Maps.
3. Cover the whole city. Google shows a limited window of results per search, so split a big city into districts or postal zones. Our guide on scraping an entire city shows how to tile Madrid or Barcelona into complete coverage.
4. Send it to your dashboard. Everything lands in Vonsel, where it becomes a mapped CRM, not a dead spreadsheet.
Where to hunt
The best Spanish cities and niches to start with
Density is your friend. A single niche search in a large metro can surface hundreds of listings, while the same query in a small town returns a handful. Match the city to your goal: volume in the big metros, higher reply rates in provincial capitals with less competition.

Agencies, clinics, hospitality, professional services
A raw CSV of 500 Spanish businesses is not a lead list. It becomes one only when you know which ones to call first, what to say, and where they sit on a map. That context is the difference between data and pipeline.

Install the extension, run one search, and watch a live lead list build itself. Free download. No trial, no credit card.
The extension is only the delivery mechanism. Once your Spanish leads are inside Vonsel, the value-added layer starts, and this is where a generic scraper stops.
Mapped CRM
Every captured business appears on an interactive map of Spain, so you can plan routes by district and see your coverage of a city at a glance.
Reviews intelligence
Vonsel reads the Google reviews of each business and surfaces pain points and buying signals, so you approach a Valencia salon knowing what its clients complain about.
AI email per business
Instead of one generic template, you get a personalized email drafted for each lead in Spanish, referencing that specific company and its context.
Website enrichment
Vonsel visits each business website to pull emails, phones and social profiles that the Maps listing alone does not show, filling gaps in your list.
Reopen and extend a scrape
Come back to a Barcelona capture later, add more districts, or attach fresh reviews to businesses you already saved. Your list grows instead of resetting.
History and organization
Every scrape is saved, so you can segment by niche and area, track lead status, and never lose the Madrid list you built three weeks ago.
A scraper hands you names. Vonsel hands you a Spanish market you can actually work
Do it right
Stay clean, stay compliant
Scraping public business information is one thing, and outreach is another. Spain applies GDPR strictly, so treat contact data with care: keep it accurate, honor opt-outs, and prefer business channels over personal ones. Our overview of whether it is legal to scrape Google Maps covers the nuances.
Technically, the extension runs in your own Chrome session, so there is no separate server key to manage. If you want the background on how browser extensions work, the official Chrome extensions documentation is a good primer.
One last principle worth repeating: scraped lists are a starting point, not a finished asset. A clean, enriched, contextualized database beats a raw dump every time, as we argue in Google Maps data vs bought lists.

Can I scrape business leads in Spain from Google Maps for free?
Yes. The Vonsel Chrome extension is a free download with no trial and no credit card. You open Google Maps, search for a niche in a Spanish city, and the extension captures names, phones, websites and more into your Vonsel dashboard.
Which Spanish cities work best for local lead scraping?
Madrid, Barcelona, Valencia, Sevilla, Zaragoza, Malaga and Bilbao have the highest business density, so a single niche search returns hundreds of listings. Smaller provincial capitals are useful when you want less competition and higher reply rates.
Is scraping public Google Maps business data legal in Spain?
Collecting publicly listed business information such as a company name, address, phone and website is generally low risk, but personal data and outreach are governed by GDPR and Spanish law. Review our legal guide and treat contact data responsibly.
