How to Do B2B Lead Generation Yourself, One Step at a Time

What Is B2B Lead Generation?

B2B lead generation is the process of identifying businesses that could buy your product or service, and getting their contact details so you can reach them. A lead is only useful when you can actually reach it: a working phone number or email, and a business that fits your target category.

A B2B lead generation tool like LeadTrapper covers the first half of that for local and service businesses. It reads what businesses publish on Google Maps into a spreadsheet, and its Number Filter and WhatsApp sender cover checking and reaching out.

Why Standard B2B Lead Generation Methods Fall Short

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

LinkedIn outreach needs a Sales Navigator subscription. Core was listed at $119.99 a month on monthly billing when checked on 24 September 2026. It also involves manual filtering and limited InMail credits. LinkedIn bans scraping outright, as does LinkedIn allow scraping explains, so it’s an option only if you work inside its own tools.

Cold email depends on a clean list and on inbox placement. Building a list means buying data or collecting addresses one by one, and spam filters remove part of what you send.

Paid advertising brings inbound leads, but you pay for each click or lead, and when the budget stops, the leads stop.

Buying lead lists gives volume but not accuracy. Contact data ages, and the same list is usually sold to many buyers. The guide to B2B lead generation lists covers what you actually receive.

How Google Maps Changes the B2B Lead Generation Math

Google Maps lists businesses in most countries, and most of them publish their own phone number, address and website, because customers use them. That makes it a strong starting point for local and service businesses, such as clinics, restaurants, gyms, agencies and suppliers. It’s a weaker source for large companies with no local presence, or for individual decision-makers.

When a recruitment agency in Singapore searches “logistics company Singapore” on LeadTrapper, the scraper searches several areas of the city, scrolls each list, and opens every listing. The result is company name, phone, address, rating, review count and website in a table, without a person copying anything by hand.

On price, Google Maps scraping with LeadTrapper costs $50 per year with no per-lead fees. Other approaches are priced monthly or per user, and the table at the end of this guide compares them.

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

Step 1: Choose your business category and location. Be specific. The more precisely you describe the segment, the more relevant each lead is. A narrow list you can contact this week beats a huge one you never work through.

Step 2: Run the scraper. Open LeadTrapper’s Google Maps scraper, enter the business type and city, and start the run. It searches several areas of the city in turn, scrolls each list to the end, and opens each listing. A large search takes minutes because it reads listings one at a time. To cover one area only, use Direct URL mode and paste the address of a Google Maps results page.

Step 3: Review and filter. The table shows rating, review count and category next to contact details. Filter out low-rated or very-low-review listings if you want established businesses only.

Step 4: Check the numbers. Phone numbers are what each business published. Run them through the WhatsApp Number Filter to remove numbers that aren’t registered on WhatsApp before you send anything.

Step 5: Export and reach out. Export to CSV, load the file into Campaign Builder, and send through the WhatsApp bulk sender. Use spin syntax so messages vary, keep the delays on, and only contact businesses you have a reason to reach.

B2B Lead Generation by Industry

The Google Maps approach suits any business that sells to local or service businesses. These are common uses.

Real estate services. Agents in Dubai, London and Toronto search property management companies and commercial property firms by area to build outreach lists.

Marketing and creative agencies. Agencies in New York, Berlin and Singapore search restaurants, retailers and small businesses by category and reach out before competitors do.

Recruitment firms. Recruiters in Mumbai and São Paulo search employers by sector, such as IT, healthcare or logistics, and contact hiring managers directly.

B2B service providers. Accountants, IT support companies and cleaning services search businesses in their service area and run focused campaigns.

Wholesale and distribution. Suppliers in Jakarta and Cairo find retailers and distributors by product category, for example electronics retailers in a city.

Rules to Know First

There are three separate questions: whether collecting from Google Maps is a crime, whether it breaks Google’s terms, and whether you can lawfully use the data. In the US, courts have read the main anti-hacking law narrowly for public pages. Google’s Maps terms still restrict mass downloading, LeadTrapper can’t grant Google’s permission, and privacy or marketing law can apply to the list you build, especially for sole traders.
