Cost per click is the pricing model behind most search and many social campaigns. In an auction like Google Ads, you rarely pay your maximum bid — you pay roughly the minimum needed to hold your position, which depends on competitors' bids and the quality of your ad. Average CPC varies enormously by industry: legal, insurance, and home-services keywords routinely cost many times more than retail or entertainment terms.
A low CPC isn't automatically good. Cheap clicks from the wrong audience waste money, while expensive clicks on high-intent searches can be the most profitable traffic you buy. That's why CPC is best judged alongside conversion rate: what matters is the cost to win a customer, not the cost to win a click.
Example
If a campaign spends $1,200 and receives 400 clicks, its average CPC is $3 ($1,200 ÷ 400).
How Sloss Digital uses it
We manage CPC through relevance and Quality Score rather than simply bidding lower — better ads and landing pages earn cheaper clicks — and we judge every keyword by the cost per qualified lead it produces.
