How to Do B2B Lead Generation: Find Verified Business Leads (2026)

What Is B2B Lead Generation?

B2B lead generation is the process of identifying businesses that could buy your product or service and obtaining their contact details so you can reach them directly. A lead is verified when you have a working phone number, email, or both — and know the business is in your target category.

847 verified business contacts per search. That is what a B2B lead generation tool like LeadTrapper returns from Google Maps in under 4 seconds — phone numbers, addresses, ratings, and websites for any business type in any city worldwide.

Why Standard B2B Lead Generation Methods Fall Short

Most businesses rely on one of four approaches, and each has a significant cost in time, money, or both.

LinkedIn outreach requires a Sales Navigator subscription at $99/month, manual profile filtering, InMail credits that run out, and response rates that rarely exceed 5%. A campaign reaching 500 decision-makers takes days to set up and weeks to play out.

Cold email gives you a 22% open rate on a good day. Spam filters remove a significant portion before they reach inboxes. Building a clean email list from scratch requires purchasing data that is often 6 to 18 months out of date, at $0.10 to $0.50 per contact.

Paid advertising generates inbound leads, but at $20 to $150 per lead for B2B campaigns on Google Ads or LinkedIn. A 100-lead campaign costs $2,000 to $15,000. When the budget stops, the leads stop.

Buying lead lists from data providers gives you volume but not accuracy. Data decays fast — business phone numbers change, companies close, categories shift. A list purchased today may be 30% inaccurate by the time your team works through it.

Google Maps has none of these problems. Every listing is actively maintained by the business that owns it. A business with an outdated number or a closed location drops off Google Maps quickly. The data is current by design.

How Google Maps Changes the B2B Lead Generation Math

Google Maps has 200 million business listings across 190+ countries. Every listing is a business that has invested time in its public presence — adding photos, responding to reviews, updating hours. These are not passive entries on a purchased list. They are active businesses.

When a recruitment agency in Singapore searches “logistics company Singapore” on LeadTrapper, it gets 400 to 800 results: company name, direct phone number, address, star rating, and website. The same search on LinkedIn would require a Sales Navigator filter, manual scrolling, and individual profile visits to find a fraction of that data.

The cost difference is equally stark. Google Maps scraping with LeadTrapper costs $50 per year. LinkedIn Sales Navigator costs $99 per month ($1,188/year). Apollo costs $99 per month. For a small or mid-sized business running regular outreach, Google Maps scraping is the only approach that scales without the cost growing proportionally.

Step-by-Step: How to Build a B2B Lead List from Google Maps

Step 1 — Choose your business category and location. Be specific. “Restaurant London” returns tens of thousands of results across the city. “Indian restaurant Shoreditch London” returns the 40 to 80 most relevant listings for that area. The more specific the search, the higher the relevance of each lead.

Step 2 — Run the scraper. Open LeadTrapper’s Google Maps scraper, enter the business type and city, set the result limit, and click Search. Results load within 4 seconds. For broad searches across a full city, run multiple narrower searches by area or neighbourhood rather than one large query.

Step 3 — Review and filter. The results table shows rating, review count, and category alongside contact details. Filter out listings with under 3 stars or under 5 reviews if you want only established businesses. Sort by rating to prioritize the highest-quality leads.

Step 4 — Export to CSV. One click exports the full table. The CSV is formatted with phone numbers ready for WhatsApp — no column reformatting, no enrichment step required.

Step 5 — Reach them on WhatsApp. Load the CSV into LeadTrapper’s WhatsApp bulk sender. Write a message template with spin syntax to vary each message. Set the auto-delay. Send. WhatsApp’s 98% open rate means the message gets read — often within minutes of delivery.

B2B Lead Generation by Industry

The Google Maps approach works for any business that sells to other businesses. These are the most common use cases across different markets.

Real estate services — Agents in Dubai, London, and Toronto scrape property management companies, landlords, and commercial property listings by neighbourhood. A morning session generates 500 to 1,000 qualified property contacts before the first call is made.

Marketing and creative agencies — Agencies in New York, Berlin, and Singapore scrape restaurants, retail chains, and SMEs by category. They reach potential clients before competitors do, using phone numbers that are verified and current.

Recruitment firms — Recruiters in Mumbai and São Paulo scrape employers by industry sector — IT companies, healthcare providers, logistics firms — and contact HR contacts directly on WhatsApp rather than through LinkedIn’s crowded InMail system.

B2B service providers — Accountants, IT support companies, and cleaning services in Lagos, Manila, and Istanbul scrape businesses in their service area and run outreach campaigns in hours rather than weeks.

Wholesale and distribution — Suppliers in Jakarta and Cairo find retailers and distributors by searching their specific product category. One search for “electronics retailer” in a city returns hundreds of shops with direct phone numbers.

B2B Lead Generation Cost Comparison

LeadTrapper is the only tool in this comparison that includes both a Google Maps scraper and a WhatsApp bulk sender in a single purchase. Every other tool requires a separate messaging platform on top of the lead generation cost.

LeadTrapper is used by B2B teams across London, Dubai, Singapore, New York, Mumbai, São Paulo, and Lagos to build verified lead lists from Google Maps and reach them directly via WhatsApp — all for $50 per year.
