How to Use Google Maps to Prospect Companies in Your Area: Practical Guide for Sales Reps

Google Maps is one of the most underused B2B prospecting tools available — and it's free. For field sales reps who sell locally, it's possible to build a qualified prospect list for an entire city or region in under 2 hours. Here's the step-by-step method.

Step-by-Step: Prospecting on Google Maps

Step 1: Define Your Search Query

Open Google Maps and search for your target industry + city. Examples: "metalworking factories São Paulo", "dental clinics Curitiba", "car dealerships Porto Alegre." Google displays all matching businesses on the map with name, address, phone, and rating.

Step 2: Filter by Qualification Criteria

Apply quick filters to identify established businesses: 3.5+ star rating, 20+ reviews, photos present, website listed, and business hours defined. Businesses missing most of these are likely too informal or inactive to be worth pursuing.

Step 3: Collect Contact Data

For each qualified prospect, collect: business name, address, phone number (often the owner's WhatsApp in Brazilian SMBs), website URL, and Google rating.

Step 4: Find the Decision-Maker

Google Maps gives you the business, not the buyer. For each prospect, search the company on LinkedIn for the owner/director, check the website's "About" page, or look up the registered representative via CNPJ on the Receita Federal website.

Step 5: Import to Your CRM

Build a spreadsheet with the collected data and import via CSV into your CRM. In Sirius CRM PRO, the Google Maps prospecting feature does this automatically — extract and import with one click from the map interface.

Best Practices

• Only contact businesses genuinely relevant to your solution
• Reference how you found them: "I found your business on Google Maps while looking for [industry] companies in [city]"
• Don't call outside business hours
• If the phone leads to WhatsApp, use a professional, personalized first message
• Store only data you legitimately use and honor opt-out requests

The big advantage of Maps prospecting: updated data (owners update it themselves), geographic focus (your territory), and enough volume to feed a healthy pipeline every month — without paying for outdated lists.
