Five tactics or one system
Bought separately, each channel competes for credit and budget. Built together, each one lowers the cost of the next.
How the compounding works
Paid buys data. Data sharpens organic and outbound targeting. Organic lowers blended acquisition cost. Automation follows up on all of it, instantly. The site converts what arrives, and every improvement lifts every channel at once.
What to build first
Almost always the conversion layer — the site or landing page — because everything upstream multiplies through it.
