A recent industry benchmark study reports the average click-through rate in Google Ads across all industries is just 6.66%. That means the vast majority of impressions don’t turn into clicks—making how you pay for those impressions a strategic decision, not just a financial one.
Cost Per Click (CPC) and Cost Per Mille (CPM) aren’t just billing options—they shape the reach, engagement, and ROI of your ad campaigns.
If you’re wondering whether CPC or CPM is the better fit for your marketing goals, this guide breaks down the key differences, benefits, and when to use each.
What Is Cost Per Click (CPC)?
Cost Per Click, also known as pay-per-click (PPC), is a pricing model where you pay only when someone clicks your ad.
This model is standard in:
- Google Ads (Search and Display)
- Facebook Ads
- Linkedin and other PPC platforms
With CPC bidding, you don’t pay for impressions; you pay for actions. This makes it ideal for performance-focused campaigns where conversions, leads, or website visits are the primary goals.
Benefits of Cost Per Click advertising:
- You only pay when someone engages
- Easier to calculate ROI
- Ideal for direct-response marketing
What Is CPM (Cost Per Mille)?
CPM, or Cost Per Mille, is the amount you pay for every 1,000 impressions your ad receives.
This model is more common in:
- Display advertising
- Programmatic platforms
- Brand awareness campaigns
- Video and social media ads
With CPM bidding, you’re charged based on visibility—not interaction. It’s a helpful model when your primary goal is reach, branding, or staying top-of-mind.
Benefits of Cost Per Mille advertising:
Great for increasing visibility at scale
Predictable spend based on impressions
Often lower cost than CPC for reach-based objectives
Feature | Cost Per Click (CPC) | Cost Per Mille (CPM) |
Pricing | Pay per click | Pay per 1,000 views |
Focus | Engagement | Reach/awareness |
Best for | Lead gen, sales, traffic | Branding, exposure |
Platforms | Search, social, display | Display, video, social |
Risk | Higher cost per action | Lower CTR risk |
When comparing Cost Per Click (CPC) to CPM, the most significant difference lies in the intent behind each. CPC is about performance. CPM is about presence.
When to Use CPC Over CPM
Choose CPC advertising when:
- You’re focus is on measurable conversions (leads, calls, form fills)
- You want tighter control over return on ad spend (ROAS)
- You’re running Google Search campaigns or retargeting ads
- You have a limited budget and need to maximize results
CPC shines in performance-driven environments where every click can be tracked and attributed.
When to Use CPM Over CPC
Choose CPM bidding when:
- You’re building brand recognition
- You want to reach a large audience quickly
- You’re running video ads or broad display campaigns
- You’re promoting content that’s not tied to direct conversion
CPM is ideal for awareness-stage marketing, especially when paired with demographic or contextual targeting.
Which Is More Cost-Effective: Cost Per Click or Cost Per Mille (CPM)?
It depends on your campaign goals.
- If your campaign is built around action, a CPC-based approach is generally more cost-effective.
- If you’re trying to increase visibility, CPM can offer more impressions for your budget—but it may require additional tracking to measure impact.
Many advertisers test both. You might start with CPM campaigns to build awareness, then retarget high-interest audiences with CPC campaigns to drive conversions.
CPC vs CPM in Google Ads
In Google Ads, you can choose CPC or CPM, depending on the campaign type.
- Search campaigns (RSA) typically use CPC bidding
- Display and YouTube campaigns can use CPM, vCPM (viewable CPM), or Target CPM
- Performance Max campaigns use automated bidding that may combine both models depending on the objective
Understanding how Cost Per Click (CPC) and CPM functions within each ad type helps you align your bidding strategy with the stage of your funnel.
Combining CPC and CPM in Your Ad Strategy
The best campaigns don’t always choose one or the other—they blend both.
For example:
- Use CPM ads to promote a new treatment program, raise brand awareness, or drive video views
- Follow up with CPC retargeting ads to drive inquiries, bookings, or assessments
This full-funnel approach ensures you’re building visibility at the top and converting interest at the bottom—without wasting ad spend.
CPC vs CPM by Industry: What to Consider
The right bidding model depends heavily on your industry. While Cost-per-click (CPC) vs. CPM comparisons are useful at a high level, your vertical plays a significant role in determining which model drives better results.
Here’s how that breaks down across common industries:
Healthcare and Behavioral Health
For addiction treatment centers, mental health clinics, and other high-trust healthcare providers, CPC is often more effective. These campaigns focus on lead generation, with clear actions such as booked assessments or form fills. Every click needs to matter—making pay-per-click advertising the better option for tracking ROI and controlling patient acquisition costs.
eLearning, SaaS, and Professional Services
CPC is still preferred, especially when the goal is to acquire free trial sign-ups, demo bookings, or consultations. These industries rely on high-intent traffic and direct-response funnels. CPM may be used for early-stage brand awareness, but Cost-per-click campaigns are typically where the performance happens.
Consumer Brands and Retail
For product launches and mass-market visibility, CPM can be effective—particularly in display or video formats. However, retargeting those impressions with CPC ads is critical to move users toward conversion. CPM vs. CPC isn’t an either-or choice—it’s sequential.
Nonprofits and Advocacy
CPM is often used for message amplification or awareness campaigns, especially when leveraging programmatic or social channels. But for donation or volunteer recruitment ads, CPC bidding becomes more helpful in tracking direct impact.
Local Services and Home Improvement
Local businesses need clicks that convert to calls or form submissions. CPC campaigns are better suited for generating leads in a defined service area. CPM may result in views but often lacks the precision needed for local intent targeting.
CPC vs CPM Depends on Intent
There’s no universally better pricing model—only a better fit for your specific campaign goal.
Use Cost Per Click when:
- You want action, not just attention
- Your funnel is performance-focused
- You need clear, measurable ROI
Use CPM when:
- You want broad visibility
- You’re launching a new service or brand
- You’re optimizing for impressions and recall
Whichever model you choose, the key is to track the right metrics, test aggressively, and align your bidding strategy with what drives results for your business.
