What Is Cost Per Click?
Cost per click (CPC) is the price an advertiser pays every time a user clicks on a paid advertisement. It is the foundational pricing model behind pay-per-click advertising on platforms such as Google Ads, Meta Ads, LinkedIn Ads, and most other digital advertising networks. You only pay when someone actively engages with your ad by clicking it, which distinguishes CPC from CPM (cost per thousand impressions), where you pay for views regardless of interaction.
In Google Ads, your actual CPC is not simply your maximum bid. It is determined by a real-time auction that factors in your maximum bid and your Quality Score, a 1-to-10 rating reflecting your ad's relevance, expected click-through rate, and landing page experience. Advertisers with higher Quality Scores can achieve better ad positions while paying less per click than competitors bidding more but with lower-quality ads.
The CPC formula when working backwards from spend: CPC = total cost / total clicks. If your campaign spent R3,000 and generated 200 clicks, your average CPC was R15.

Quality Score and Its Impact on CPC
Quality Score is the single biggest lever for reducing CPC without reducing your bid. Google calculates it from three components: expected CTR, ad relevance, and landing page experience. Each component is rated "Below average", "Average", or "Above average". A Quality Score of 7 or higher typically earns you a CPC discount relative to competitors at the same bid level.
Practical steps to improve Quality Score and lower CPC include: writing ad headlines that closely match the keywords you are bidding on; creating dedicated landing pages for each ad group rather than sending all traffic to your homepage; ensuring your landing page loads in under 2.5 seconds (especially important on South African mobile networks); and using responsive search ads that allow Google to test multiple headline and description combinations automatically.
CPC vs CPM: Which Should You Choose?
For direct response campaigns where you want clicks and conversions, CPC bidding keeps you in control of per-click costs. For brand awareness campaigns where you want maximum visibility and are less concerned with clicks, CPM (cost per thousand impressions) can be more efficient. Most South African advertisers running lead generation or e-commerce campaigns benefit from CPC or target CPA bidding rather than CPM.
