PPC — pay-per-click — is online advertising where you are charged each time someone clicks your ad, rather than for showing it. Google Ads is the best-known example: you bid on search terms, and your ad competes for placement when people search them. Social and display networks run on the same basic model.
Where SEO earns traffic over time, PPC buys it on demand — useful for launches, promotions, and testing demand quickly. Cost depends on competition and on relevance: platforms reward ads and landing pages that match what the searcher wants with lower prices and better positions. Spend is easy to start and just as easy to waste without close attention.
That attention is the hard part — fresh copy, sharp targeting, matched landing pages, and budget following what converts, every day. It's exactly the repetitive optimization an AI system can run continuously, which is the idea behind our AI-run Google Ads engine.
