What is PPC, and how does it work?
PPC stands for pay-per-click: you only pay when someone actually clicks your ad, not when it's shown. Google Ads Help describes an auction that decides both where your ad appears and what that click costs.

How does the auction work?
Your position comes from Ad Rank, which combines your maximum bid, expected click-through rate, ad relevance, landing page quality and the expected impact of assets. Crucially, Google states that "you only pay what's minimally required to clear the Ad Rank thresholds and beat the Ad Rank of the competitor immediately below you" — and that you're "never charged more than your max. CPC bid."
So the highest bidder doesn't automatically win, and the winner usually pays less than they offered.
What does that mean for your money?
| If you improve | What happens |
|---|---|
| Ad relevance | Ad Rank rises, cost per click can fall |
| Landing page quality | Same — quality is priced in |
| Expected click-through rate | Better position for the same bid |
| Nothing, and just bid more | You pay more for the same result |
This is why better ads are genuinely cheaper, not just more effective.
What makes a PPC ad perform?
Google Ads Help's own tips are plain: highlight what makes you different, include prices and offers, use a clear call to action, include a keyword in the ad text, and make sure the landing page actually contains what the ad promised. It also recommends testing three or four different ads per ad group.
Is PPC the same as Google Ads?
No. Google Ads is one PPC platform; the model also appears on Meta, TikTok and others. See how Google Ads works and what CPM, CPC and CTR mean.
