TL;DR
Cost Per Click (CPC) is the price paid per click on a paid advertisement, typically in search, display or social channels. It is the upper-funnel cost metric of paid acquisition, sitting two steps before CPA. CPC matters less for affiliate work and more for performance marketing teams running paid media campaigns where bid management, ad copy and landing page quality all interact to determine final acquisition economics.
Formula
In its simplest form:
In paid search and most modern paid social platforms, CPC is determined by an auction. The advertiser sets a bid, the platform applies its quality and relevance scoring and the resulting CPC is the price per click that occurs. CPC at the campaign level is calculated post-hoc from total spend divided by total clicks.
A typical warehouse-level aggregation:
Warehouse-level aggregationSELECT
channel, campaign_id,
SUM(spend) AS total_spend,
SUM(clicks) AS total_clicks,
SUM(spend) * 1.0
/ NULLIF(SUM(clicks), 0) AS cpc
FROM paid_media_metrics
WHERE date BETWEEN :start AND :end
GROUP BY channel, campaign_id;Why it matters in iGaming
CPC is the price tag on attention in paid acquisition. It sits at the top of the funnel and feeds every downstream metric: a click might convert to a registration (lead) or not, a registration might convert to FTD or not. CPC alone tells you nothing about acquisition outcomes, but it tells you how efficiently you are buying entry into the funnel.
Different teams use CPC differently:
- Performance Marketing optimises CPC through bid strategies, ad copy, audience targeting and landing page quality.
- Marketing tracks CPC trend by channel and keyword as a competitive intensity signal.
- Acquisition uses CPC as input to forecasting (expected click volume at given budget) and as a sanity check on bidding strategy.
- Finance treats CPC mainly as a component of CPA, not as a standalone target.
CPC in iGaming has some structural quirks. Many regulated markets have advertising restrictions that limit which keywords can be bid, which platforms can be used and which creatives can be shown. CPC in iGaming on regulated platforms tends to run higher than in unrestricted verticals because of supply constraints. Comparing iGaming CPC to general retail or SaaS CPC misleads in both directions.
Common mistakes and how teams get CPC wrong
Optimising CPC at the expense of conversion. A campaign that drives down CPC by targeting cheap, low-intent keywords delivers cheap clicks that do not convert. The right north star is CPA or LTV-to-CPA ratio, with CPC managed in service of those goals.
Comparing CPC across very different markets. Regulated markets with brand restrictions show very different CPC dynamics from unrestricted markets. Same operator, same keyword, very different CPC. Cross-market CPC benchmarking without regulatory context is misleading.
Confusing CPC with bid. The bid is the maximum the advertiser is willing to pay. The CPC is the actual price paid per click, often lower than the bid because of platform auction dynamics. Reporting bid as CPC inflates the apparent cost of clicks.
Ignoring quality score impact. On platforms like Google Ads, ad and landing page quality directly affect CPC. Two advertisers bidding the same amount can pay very different CPCs based on quality score. Operators that focus only on bid management without quality optimisation overpay.
Reading aggregate CPC without keyword-level breakdown. A single campaign-level CPC averages across many keywords with very different CPC profiles. Optimisation happens at keyword level, not campaign level. Reports that aggregate too much hide the real cost picture.
Healthy ranges and benchmarks
CPC varies dramatically by platform, keyword, market and competitive intensity. Directional patterns:
- Branded search keywords (operator's own brand name) typically have very low CPC, often under 1 EUR, because relevance is high and competition is light.
- Generic high-intent keywords ("best online casino", "sportsbook bonus") command meaningfully higher CPC, often in the high single digits to low double digits.
- Paid social CPC tends to be lower than paid search CPC, but converts at lower rates.
- CPC during major sports events spikes as competition for ad inventory rises.
- Mature regulated markets often show structurally higher CPC than emerging or grey markets, particularly on premium platforms.
These are directional patterns based on industry observation, not strict benchmarks. CPC management is most useful as a within-channel optimisation discipline rather than a cross-operator benchmark.
How Gamblitude handles CPC
CPC is primarily a paid media platform metric, ingested into Gamblitude alongside other channel-level cost data. The platform exposes CPC as part of the broader acquisition reporting view, paired with downstream conversion rates and CPA so Marketing teams see the full funnel economics rather than CPC alone. Insight Radar surfaces meaningful drift in channel CPC or click-to-conversion ratios that would otherwise show up only at the monthly acquisition review.
FAQ
No. Low CPC on traffic that does not convert is wasted spend. The right framing is CPC in service of CPA: clicks need to convert at rates that justify their cost. Many of the cheapest clicks come from the worst-converting keywords.
Paid search CPC is typically higher because the user is actively searching with intent. Paid social CPC is typically lower because the platform interrupts users not actively searching, but conversion rates are correspondingly lower. Both are valid channels with different economics.
Because of advertising restrictions and competitive intensity. Many regulated markets allow only licensed operators to advertise on premium platforms, which concentrates competition for limited inventory and pushes CPC up. Some keywords are entirely prohibited, which displaces demand toward remaining permitted terms.
CPA, with CPC managed as a component. Optimising CPC alone often hurts CPA by pushing toward cheap, low-converting clicks. The right discipline is to optimise the full funnel with CPC managed at the bid and quality-score level, conversion managed at the landing page level, and the whole stack judged by CPA outcomes.
Significantly. On Google Ads, two advertisers bidding the same amount on the same keyword can pay very different CPCs based on quality score, which reflects ad relevance, click-through rate and landing page quality. Operators that invest in landing page optimisation typically achieve materially lower CPC for the same bid.
