What Is CPC?
Cost per click (CPC) is the amount you pay each time someone clicks on your ad. It's the most common pricing model for search advertising (Google Ads, Microsoft Ads) and is also used in social and display campaigns.
CPC = Total Ad Spend ÷ Total Clicks. If you spent $500 and received 250 clicks, your CPC is $2.00. CPC is directly tied to CTR — a higher CTR generally lowers your effective CPC in auction-based systems because the platform rewards relevant ads.
Average CPC by Platform — 2026
LinkedIn is consistently the most expensive platform due to its professional audience — B2B advertisers pay a premium for intent. TikTok remains the cheapest on a per-click basis but audience intent varies by campaign objective.

CPC vs. CPM — Which Pricing Model Is Better?
CPC and CPM are the two dominant pricing models. The right choice depends on your campaign objective.
Choose CPC when
Your goal is traffic or conversions. You pay only when someone clicks — no wasted spend on unengaged views.
Choose CPM when
Your goal is awareness or reach. You pay per thousand impressions regardless of clicks — better for brand campaigns.
When CPC is cheaper
High-CTR campaigns with strong creative. If CTR is 3%, your eCPM of $10 = $0.33 CPC — better than platform average.
When CPM is cheaper
Low-CTR placements (display, video). If your CTR is 0.1% on display, CPC bidding at $0.63 avg becomes expensive vs. flat CPM.
How to Lower Your CPC
| Method | How It Works | Impact |
|---|---|---|
| Improve Quality Score | Google rewards relevant ads with lower CPCs. Better CTR → higher QS → lower auction price. | High |
| Tighten audience targeting | Narrow to high-intent users. Less waste, better CTR, lower effective CPC. | High |
| Use long-tail keywords | More specific queries have less competition and lower CPCs, often with higher conversion intent. | High |
| Improve ad relevance | Match ad copy closely to keyword intent. Higher relevance = higher CTR = lower CPC in auctions. | Medium |
| Adjust bidding strategy | Switch from Max CPC to Target CPA or ROAS if you have enough conversion data. | Medium |
| Schedule ads | Reduce bids or pause during low-conversion hours to avoid wasted clicks. | Medium |

What is CPC in advertising?
CPC (cost per click) is the price you pay each time a user clicks on your ad. It's calculated as total spend divided by total clicks. CPC is the standard pricing model for Google Search ads and is also used across social and display platforms.
What is a good CPC?
It depends entirely on your industry and what a click is worth to you. A $5 CPC is cheap for a legal firm where a client is worth $10,000. It's expensive for a $20 product. Always evaluate CPC against your conversion rate and CPA.
Why is my CPC so high?
High CPC usually comes from low Quality Score, highly competitive keywords, or broad targeting. Start by improving your ad relevance and landing page experience — Google directly rewards this with lower CPCs.
How does CTR affect CPC?
In auction-based systems like Google Ads, higher CTR improves Quality Score, which lowers the minimum bid needed to win auctions. Better click-through rates mean you pay less for the same placement.
What's the difference between CPC and CPM?
CPC is pay-per-click — you pay only when someone clicks. CPM is pay-per-thousand-impressions — you pay for views regardless of clicks. Use CPC for performance campaigns, CPM for awareness campaigns.
