Google Maps vs Facebook for B2B Prospecting

Google Maps and Facebook seem to be made for two different uses. One helps you find a restaurant closed on Sundays, while the other shows you photos of your high school friends. But in reality, both platforms are lead generation machines for B2B — if you know how to use them.

The question is not "which one to choose," but rather "which one works for MY industry, and how to automatically extract data without wasting 40 hours a month."

This guide compares the two platforms on concrete criteria: data quality, targeting, ROI, and shows you how IBLead transforms Google Maps into a lead factory.

Comparison of Extracted Data

What You Find on Google Maps

Basic Data (100% of listings): - Business name - Full address (street, city, postal code) - Phone - Website - Category(ies) - Opening hours - Number of photos - Google Place ID

Quality Data (70-90% of listings): - Google rating (average) - Number of reviews - Complete reviews (text, author, date, rating) — EXCLUSIVE TO IBLead - Enriched email from the website — EXCLUSIVE TO IBLead - Social media (Facebook, Instagram, YouTube, LinkedIn, Twitter)

Advanced Data (with IBLead): - 160+ detected technologies (WordPress, Shopify, HubSpot, Google Analytics, etc.) — EXCLUSIVE TO IBLead - SIRET, SIREN, APE, manager (France only) — EXCLUSIVE TO IBLead - SEO title of the site, meta-description - Presence of advertising pixels (Facebook Pixel, Google Ads, etc.) - Detected contact forms

What You Find on Facebook

Basic Data (if provided): - Page name - Address - Phone number - Email (rarely) - Website (link) - Category (very basic)

Engagement Data: - Number of followers - Last post - Engagement rate (if you have access to the page) - Private messages (Messenger)

Missing Data: - Structured reviews (Facebook has no equivalent to Google reviews) - Site technologies - Automatic enrichment data - SIRET/SIREN data

The Facebook Problem: 85% of business pages do not update their information. You find outdated addresses, inactive phones, emails that are never checked.

Targeting: The Major Difference

Google Maps: Exhaustive Targeting

By Geography: - Search by city (e.g., "Plumbers in Paris") - Search by department - Search by region - Search by entire country - Search by radius (5 km, 10 km, etc.)

By Activity: - 3,000-4,000 available categories - Specific subcategories (e.g., "French Restaurant", "Vegetarian Restaurant", "Gourmet Restaurant") - Combination of categories

By Quality: - Filter by rating (2-5 stars) - Filter by number of reviews (min/max) - Filter by presence of email - Filter by presence of website - Filter by presence of phone - Filter by number of photos - Filter by claimed/unclaimed listing — EXCLUSIVE TO IBLead

Real Use Case: You sell practice management software. You search for "Lawyers in Lyon" + filter "rating > 4" + filter "website" = 47 qualified leads. Setup time: 2 minutes.

Facebook: Limited Targeting

By Geography: - Search by region - Search by city (imprecise)

By Activity: - Only ~20 categories - No subcategories - No combinations

By Quality: - No automatic filters - You must manually check each page

The Facebook Problem: If you search for "Lawyers in Lyon", you find 3-5 pages, some of which are personal pages or outdated pages. No sorting by rating, no structured data.

Where IBLead Wins on Raw Google Maps

1. Google Reviews Automatically Scraped

Google Maps displays reviews, but you cannot download them in bulk. With IBLead, you extract: - Full text of each review - Rating (1-5 stars) - Publication date - Author's name

Use Case: You are prospecting restaurants. You find 500 restaurants in Paris, then filter those with < 3 stars. You contact the manager: "I saw that your customers are complaining about slow service. I offer an order management solution that reduces delays by 40%."

Conversion rate: 3x higher than generic prospecting.

2. Detection of 160+ Technologies

IBLead automatically detects if a business uses WordPress, Shopify, WooCommerce, HubSpot, Mailchimp, Google Analytics, Facebook Pixel, etc.

Concrete Use Case: - You sell a WordPress plugin. You search for "Restaurants in Paris" + filter "WordPress". Result: 120 leads that are ALREADY using WordPress. - You sell HubSpot. You search for "Marketing Agencies in France" + filter "HubSpot". Result: 340 leads that are YOUR CURRENT USERS (you call them for upsell).

Impact: Conversion rate x10 vs cold prospecting.

3. Automatic SIRET/SIREN Matching (France)

With IBLead, each French business is matched with INSEE Sirene data: - SIRET (identification number) - SIREN (group number) - Legal form (SARL, SAS, EIRL, etc.) - APE code - Manager's name - Date of creation - Revenue (if public)

Use Case: You sell payroll software. You search for "Restaurants in Paris" + filter "SARL" + filter "10-50 employees". You find exactly the restaurants that need automated payroll.

4. Emails Enriched from the Website

Google Maps does not display business emails. IBLead automatically extracts them from: - Contact page of the website - Footer of the site - Forms - Whois of the domain

Result: 70% of exported listings include a direct email, without third-party enrichment.

Where Facebook Wins (Honestly)

1. Direct Communication via Messenger

On Facebook, you can send a private message to a page and get a response. It is a direct communication channel that Google Maps does not have.

Use Case: You are an event agency. You find a restaurant on Facebook, you send them a Messenger: "Hello, I offer corporate events. Are you interested?" Response in 30 minutes.

With Google Maps, you have to call or send an email.

2. Visual Content and Engagement

Facebook allows businesses to post photos, videos, and engage their audience. If you are prospecting in a visual sector (restaurants, hotels, salons), you can assess the quality of the establishment in 10 seconds.

Google Maps also has photos, but Facebook allows for smoother navigation.

3. Audience and Followers

The number of followers on Facebook can indicate a business's popularity. It is a quality signal that Google Maps does not have as clearly.

Who Should Use What?

✅ Google Maps + IBLead: Recommended for

All B2B sectors: - Lawyers and law firms - Architects and engineering firms - Marketing and advertising agencies - Garages and automotive services - Plumbers, electricians, heating engineers - Accountants and auditors - Real estate agencies - Pharmacies - Agricultural sector - IT providers and developers

B2C sectors with a large database: - Restaurants (to sell management software) - Hotels (to sell booking services) - Beauty salons (to sell appointment scheduling software)

Reason: Google Maps covers 200M businesses. Facebook covers ~50M, with very uneven coverage. For B2B, Google Maps is essential.

✅ Facebook: Recommended for

Pure B2C sectors with a strong visual component: - Restaurants (prospecting end customers) - Hotels (prospecting end customers) - Beauty salons (prospecting end customers) - Events (to see live events) - Retail (fashion, decoration shops)

Reason: Facebook is a direct communication channel. If you sell services to restaurants (e.g., management software), Google Maps is better. If you sell to restaurant customers (e.g., reservation app), Facebook can be complementary.

🎯 Optimal Hybrid Strategy

Phase 1 — Identification (Google Maps + IBLead) - Export your prospects from Google Maps - Apply precise filters (rating, reviews, technologies, SIRET) - Obtain 1,000 qualified prospects in 10 minutes
Phase 2 — Enrichment (Facebook) - Check if your prospects have a Facebook page - Review their engagement, followers, photos - Enrich your understanding of the prospect
Phase 3 — Prospecting (Email + Messenger) - Send a personalized email based on Google Maps data - Complement with a Messenger message if the page exists - Response rate: 2-3x higher
