Cost Per Click (CPC) is a pricing model and metric used in paid advertising where you pay each time someone clicks on your ad. Rather than paying for impressions (views) or conversions (actions), you pay per click. It's the fundamental unit of cost in paid search advertising and is increasingly common in other advertising channels.
CPC is calculated simply: take your total ad spend and divide it by the number of clicks you received. If you spent £1,000 on Google Ads and received 500 clicks, your CPC is £2. This metric tells you how much you're paying, on average, for each click that reaches your website.
CPC is a starting point, not an endpoint. A low CPC is good if those clicks convert; a high CPC is acceptable if it delivers qualified leads. The real metric that matters is cost per conversion, which depends on both your CPC and your conversion rate.
For B2B growth teams using paid advertising, CPC is the lever you pull to manage campaign profitability. If your CPC is too high, your cost per acquisition becomes prohibitive. If your CPC is too low, you might be bidding too conservatively and missing valuable traffic.
Understanding CPC across channels helps you allocate budget effectively. If LinkedIn delivers leads at a lower cost per acquisition despite higher CPC, it's because the quality of LinkedIn clicks is higher. You might increase LinkedIn budget and decrease display budget, even though display has lower CPC.
CPC also reveals competitive intensity. If a keyword's CPC spiked from £1.50 to £3.00, that often means more competitors entered the market or seasonal demand increased. Monitoring CPC trends helps you stay aware of competitive dynamics and adjust strategy accordingly.
To optimise your CPC, start by improving your Quality Score (on Google) or Relevance Score (on other platforms). These scores depend on your ad copy relevance, landing page quality, and click-through rate. Improving these scores lowers your CPC directly. Write ad copy that matches search intent, and ensure your landing pages are relevant to your ads.
Refine your keyword targeting. Broad keywords typically have lower CPC but attract less qualified clicks. Specific, long-tail keywords usually have higher CPC but attract more qualified prospects. Test to find the right balance for your business. Negative keywords reduce wasted clicks: if you sell enterprise software, add 'free' and 'open source' as negative keywords to avoid clicks from those searching for low-cost options.
Bid strategically based on expected conversion value. You don't need to minimise CPC uniformly; instead, bid higher for keywords and audiences you know convert well, and bid lower for unproven keyword clusters. Use conversion tracking to feed back which clicks led to conversions, then adjust bids accordingly.
A project management software company started bidding on broad keywords like 'project management software', paying £3.50 CPC. After analysis, they realised their highest-converting traffic came from specific keywords like 'agile project management software for enterprise' (£5.20 CPC) and 'project management software for technical teams' (£4.80 CPC). They shifted budget toward these specific keywords, accepting slightly higher CPC to get higher-conversion traffic, and reduced cost per customer by 35%.
A B2B consultancy ran LinkedIn ads targeting Chief Financial Officers at companies with £100M+ revenue. Initial CPC was £4.50 and lead cost was £180. They refined targeting to only companies in financial services (their best-converting vertical), which increased CPC to £5.20 but reduced lead cost to £110 due to much higher conversion rates. The higher CPC was more than offset by better-qualified clicks.
An HR software company noticed their competitor changed their website messaging. They started bidding on competitor brand keywords, achieving £6.80 CPC because competitors were bidding aggressively to defend their brand. Despite the high CPC, the conversion rate from competitor brand searchers was 12%, resulting in a cost per lead of £57. The high CPC was justified by the conversion rate.
