Scrape Google Maps: complete guide to extracting business data

Google Maps is the world's largest business database. Millions of listings with name, address, phone, website, hours, ratings and reviews — all publicly accessible. For a sales rep or an agency, it's a goldmine. You just need to know how to tap into it.

This guide explains how to extract this data efficiently, the limits you should know, and the tools available in 2026.

Why Google Maps is the best source for prospecting

Unlike traditional directories, Google Maps is continuously updated by the businesses themselves. Google Business Profile listings contain rich, verified data: contact details, hours, photos, and especially customer reviews that let you filter for active, reputable businesses.

The other major advantage: geographic coverage. Whether you're looking for restaurants in Paris, plumbers in London or hotels in Bali, Google Maps covers the entire world with the same level of detail.

What you can extract from a Google Maps listing

Each business listing potentially contains all of this data:

• Business name and activity category
• Full address with GPS coordinates (latitude, longitude)
• Phone number — present in about 90% of listings
• Website — present in about 75% of listings
• Google rating (out of 5) and number of reviews
• Opening hours
• Status — active, temporarily closed, or permanently closed
• Main photo
• Direct link to the Maps listing

That's already a very complete profile to start a prospecting campaign. And with the website, you can go further by extracting the professional email.

The 100-result limit

The main problem with Google Maps: searches are limited to about 100-120 results per query. If you search "Restaurant Paris", Maps will show around a hundred results, when there are thousands.

This is a technical limitation of the interface, not the database. Google has the data but doesn't display it all. To overcome this limit, you need to split the geographic area into smaller cells and run a search in each one.

Extraction methods

Manual method (copy-paste)

Open Maps, search, copy each listing into a spreadsheet. Functional for 10-20 businesses, unsustainable beyond that. Expect 2-3 minutes per listing, or 5 hours for 100 businesses.

Browser extensions

Chrome extensions can extract visible results from the Maps page. Limited to the 100 displayed results, often unstable, and data is sometimes incomplete. A decent compromise for small volumes.

Google Places API

The official API provides structured data access. The problem: cost. Each request is billed, and extracting thousands of listings can quickly cost hundreds of euros. The API also enforces strict quotas.

Dedicated scraping tools

Specialized software automates collection by simulating Maps navigation. This is the most efficient method for large volumes: thousands of results in minutes, with all data structured and ready to export.

From extraction to prospecting: email enrichment

Having a company's name, phone and website is good. Having their professional email is better. The next step after Maps extraction is scanning company websites to find email addresses.

An enrichment tool crawls contact pages, legal notices, footers and internal pages of each site to detect emails. The success rate depends on the type of business: local shops often display their email, large companies hide it behind forms.

On average, expect a detection rate of about 60-70% on businesses that have a website.

Best practices

Target precisely. "Restaurant" will yield more results than "Fine French dining restaurant". Use simple terms and make multiple separate searches rather than one overly specific search.

Adapt depth to your needs. For occasional prospecting, a hundred results is enough. For market research or directory building, aim for exhaustive coverage.

Filter results. Remove listings without a website (no enrichment possible), closed businesses, and those with very low ratings if reputation matters for your approach.

Export cleanly. A well-structured CSV or XLSX file with consistent columns will save you hours when importing data into your CRM or emailing tool.

Is it legal?

Data publicly displayed on Google Maps is public data. Its collection is permitted for B2B prospecting under legitimate interest (GDPR). However, you must respect the rules for using collected data: allow unsubscription in your emails, don't resell raw data, and don't contact people who have expressed refusal.

Summary

Google Maps remains in 2026 the most complete and up-to-date source for identifying businesses by sector and location. The key to getting the most out of it is overcoming the 100-result limit with GPS gridding, then enriching the data with professional emails extracted from websites.

This is exactly the workflow ContactEra offers: Maps targeting with adjustable depth, automatic email enrichment, and one-click export.
