SEA / Paid Search

PPC

PPC (pay-per-click) is any advertising model where you pay only when someone clicks your ad.

In detail

The click price is set by auction and adjusted by ad quality, so relevance directly lowers cost.

PPC is the pricing model; SEA is search advertising specifically. Not all PPC is search.

Example

Paying €2.40 for a click on a search ad but nothing for the impressions that were not clicked.

Why it matters

It makes cost per outcome measurable, which lets you decide budgets from unit economics.

Common mistakes

  • Optimising for cheap clicks that never convert.
  • Confusing impressions with reach that matters.
