Project Summary

Case Study: B2B Data Mining & Lead Generation

Objective:

Following the pause of SEO and SEA initiatives in November 2024, I led a GDPR-compliant, high-volume B2B data mining project. The primary goal was to expand digital reach and generate leads in new international markets, particularly within Europe.

Strategy & Workflow:

Market Selection: Countries targeted included DACH, UK, France, Netherlands, Italy, and later USA, China, and Australia.
Prospect Collection: Used LinkedIn Sales Navigator with ChatGPT to export and organize filtered leads.
Data Import & Enrichment: Imported leads into Salesforce or spreadsheets and enriched data via Hunter.io and LeadIQ.
Email Outreach: Executed campaigns focused on education and relevance, not direct sales.
Lead Progression: 38-40% of leads moved to Step 2 of email sequences.
Webinar Promotion: Used webinars to convert prospects and drive brand engagement.

Results:

40,000 to 60,000 leads generated monthly
38-40% Step 2 engagement per campaign group
60-70% of webinar registrations came from email outreach

GDPR Compliance:

B2B contact data only, publicly available
No sensitive data shared or stored
Behavior tracked through non-personal metrics (clicks, signups)

Lead Generation Workflow:

LinkedIn Sales Navigator
Extract 25 Contacts/Page using ChatGPT
Import to Salesforce or Spreadsheets
Email Outreach Campaigns
- Step 1: Awareness Email
- Step 2: Triggered by Engagement
Brand Awareness + Webinar Invites
Analysis of Conversions & Registrations

Innovation & Ownership:

Designed full data mining workflow from scratch
Used ChatGPT for scalable data handling
Maintained lead organization and status updates manually when needed

Outcome:

Despite zero paid ads or SEO post-November, this strategy kept digital visibility and lead generation active, while also expanding into new markets.
