How CPC Works in Google Ads
Google Ads uses a second-price auction model. You set a maximum CPC bid, but you often pay less than your max. Your actual CPC is calculated as: (Ad Rank of the advertiser below you / your Quality Score) + $0.01. This means improving your Quality Score directly lowers what you pay per click. Manual CPC gives you full control over bids, while automated strategies like Maximize Clicks or Target CPA adjust bids dynamically based on auction signals.
