Common Lead Generation Mistakes
-
Over-investing in tools without process: Tools don't generate leads, people do. Invest in people/process first.
-
Building huge prospect lists without qualification: 10,000 unqualified leads is worthless. Start with 500 highly qualified ones.
-
Ignoring data quality: A small list of clean, accurate data beats a large list of stale data.
-
Not integrating with CRM: If leads don't flow into your CRM, sales won't follow up.
-
Measuring wrong metrics: Track pipeline revenue, not just leads generated.
