Lead Generation Types—Seeds, Nets, and Spears Will Reshape Your Marketing Strategy

Sam, a marketing manager for a tech company, believed all leads were created equal. Every month, reports lumped web form signups together with referrals and conference contacts. But, as conversion rates began to slip, Sam’s team adopted a new way to classify their pipeline: Seeds (referrals, word-of-mouth), Nets (broad ad campaigns or events), and Spears (targeted outreach).

Over the next quarter, they tracked and compared each. Seeds—the loyal, network-grown connections—took time to develop, but they closed at the highest rate and brought in repeat business. Nets delivered volume, but many leads dropped off quickly. Spears, while labor-intensive, allowed exact targeting and gave steady, controllable growth. By splitting strategies—and budgets—along these three lead types, Sam freed his team from old assumptions and designed campaigns that aligned with each group’s unique strengths.

This tripartite approach soon became a game-changer. Instead of arguing about which channel was “best,” the team had language and numbers to refine their strategy each month. Behavioral science, after all, shows that breaking down big, messy categories into useful subgroups enables smarter experimentation and continuous improvement.

This week, grab your pipeline or contact list and label where each lead comes from: is it a Seed (personal, trusted), a Net (mass ad or event), or a Spear (targeted outreach)? Track which converts best—not just on a hunch, but with real numbers. Then, shift a bit more budget or attention to your best performer, while adjusting how you nurture each type. Do this monthly, iterating as you learn, for smarter, more predictable growth.
