Digital Marketing Foundations & Full-Funnel Growth
Understand customer acquisition funnels, CAC vs LTV unit economics, and digital channel attribution.
The Modern Digital Marketing Landscape & Core Economics
Digital marketing operates like a quantitative engineering discipline centered on Customer Acquisition Cost (CAC), Lifetime Value (LTV), retention cohorts, and data-backed conversion optimization. A sustainable business targets an LTV:CAC ratio of at least 3:1.
- •Top of Funnel (TOFU): Cold discovery and awareness via Meta Reels, YouTube Shorts, and educational guides.
- •Middle of Funnel (MOFU): High-intent consideration via Google Search Ads, lead magnets, and retargeting.
- •Bottom of Funnel (BOFU): Decision and purchase via branded search, direct sales counseling, and automated follow-ups.
Channel Architecture: Owned vs. Paid vs. Earned Media
A resilient growth strategy avoids dependence on any single ad network by balancing owned email/SMS lists, paid performance channels, and organic earned search authority.
- •Owned Media: Zero-marginal-cost customer assets (email lists, CRM records, community groups).
- •Paid Media: Scalable, on-demand traffic channels (Google Ads, Meta Ads, LinkedIn Ads).
- •Earned Media: Organic search rankings, customer word-of-mouth, and media press.
