PPC (Pay-Per-Click)
Paid advertising where you pay each time someone clicks your ad.
PPC (e.g. search and social ads) buys traffic quickly and is highly measurable, letting startups test demand and scale acquisition. Costs can rise fast, so disciplined tracking of CAC, conversion and payback is essential to keep it profitable.
Examples
A startup runs PPC to validate a landing page before building. — Paid ads scale signups once CAC is below LTV.
