Plain answer
PPC (pay-per-click) is advertising where you pay only when someone clicks your ad, not when it's shown. Google Ads search is the classic example: you bid on what people type, your ad appears, and a click costs you money while an ignored ad costs nothing.
How PPC actually works
You choose who should see your ad — by search keyword, audience, or profile — and tell the platform the most you'll pay for a click. An auction runs every time someone matching your target shows up. Win, and your ad appears; pay only if they click. The model's appeal for an owner is that the meter starts at interest, not exposure.
The price of a click isn't fixed. It moves with competition and with how relevant the platform judges your ad — the mechanics live under CPC and Quality Score.
PPC vs SEO: which one first?
Search engine optimization earns visits over months; PPC buys them this afternoon. That's the whole trade. A new business needing customers this quarter can't wait for rankings; an established site with strong rankings shouldn't pay for clicks it would get free. Most businesses that get this right run both, using PPC to cover the searches their organic presence doesn't win yet.
Is PPC worth it for a small business?
It's worth it when the arithmetic closes: click cost × clicks-per-customer comfortably below what a customer is worth. It's not worth it when the budget is too small to produce decisions, or when nobody is watching the account — unmanaged PPC leaks money through irrelevant searches, and the platform will not stop it for you. The search terms report is where those leaks show up; someone has to read it.
Field note from TomasThe real price of PPC isn't the clicks. Managing $85M+ in ad spend is what taught me the lessons; owners who self-teach re-buy those mistakes with money, time, iterations, and frustration — while being pulled away from the work they actually earn the most from. There's a time and place for DIY. Just count the tuition honestly.
What this means for your ads
Start with searches that signal a wallet — "hire," "cost," "near me" — and build outward from what converts. PPC rewards the boring disciplines: exact tracking, negative keywords, weekly attention. The clicks are auctioned; the profit goes to whoever manages them.
