The average amount you pay each time someone clicks your ad.
Cost Per Click is the price you pay for each click on a paid ad. On auction platforms like Google Ads and Meta Ads, CPC is not a fixed rate: it is set by an auction that weighs your bid against ad quality and competition, so a better, more relevant ad can often win clicks for less.
CPC is a cost efficiency metric, not a success metric. A low CPC is worthless if those clicks do not convert, and a high CPC can be perfectly profitable if the resulting customers are valuable enough.
In Google Ads, actual CPC is driven by Ad Rank, which combines your bid, Quality Score and expected impact of ad extensions. Because quality is part of the formula, improving relevance and landing-page experience can lower your CPC without raising bids.
Chasing the lowest possible CPC in isolation, which usually means bidding on cheap, low-intent keywords that never convert. Judge CPC only alongside conversion rate and cost per acquisition, never on its own.
The share of people who click after seeing your ad or search result.
Google Ads’ 1-to-10 rating of the quality and relevance of your keywords and ads.
Revenue generated for every unit of currency spent on advertising.
Common questions
Straight answers on how this fits your marketing and build.
No. Cheap clicks that never convert waste budget, while more expensive clicks from high-intent buyers can be highly profitable. Always read CPC alongside conversion rate and cost per acquisition.
