In digital advertising, CPM (Cost Per Mille, or cost per 1,000 impressions) is often treated as a key performance indicator. And sure, it can be useful. But here’s the truth: a low CPM doesn’t automatically mean your campaign is successful, and chasing cheaper impressions can distract you from what actually matters. The bottom line, though? CPM isn’t everything.
We know that the real measure of a campaign’s success is tied to results, not just reach. Here’s why CPM shouldn’t be the star of your performance reports, and what to focus on instead.
1. A Low CPM Doesn’t Guarantee Engagement or Conversions
CPM tells you how much you’re paying to get your ad seen 1,000 times. But impressions don’t equal action. You could have a rock-bottom CPM and still have no clicks, leads, or sales.
Let’s say you pay $5 CPM and get 100,000 impressions for $500. If that results in zero conversions, what did that CPM really do for you?
✅ Instead, focus on these metrics:
- CTR (Click-Through Rate): Are people actually engaging with your ad?
- Conversion Rate: Are those clicks turning into purchases, signups, or inquiries?
- Cost Per Result (CPR): How much are you paying for the outcomes that matter to your business?
Those numbers tell a much clearer story about whether your budget is being spent wisely.
2. Audience Quality Matters More Than Impressions
High impressions at a low cost can look great on paper, but if you’re not reaching the right audience, it’s wasted effort. A highly targeted audience may come with a higher CPM, but those impressions are much more likely to convert.
Here’s a quick comparison:
| Campaign A | Campaign B |
| $3 CPM, broad audience | $9 CPM, highly targeted |
| 100,000 impressions | 30,000 impressions |
| 5 conversions | 40 conversions |

3. Campaign Objectives Drive Smarter Decisions
When you’re goal-focused, you build your campaign around what matters most. Whether it’s generating leads, driving website traffic, or boosting app downloads, your strategy should be guided by your objective, not your CPM.
Here’s how we help clients at Mad Men Marketing shift the focus:
- Define your primary goal (e.g., form submissions, e-commerce sales, store visits).
- Choose the right platform and format to support that goal.
- Use real-time analytics to optimize for performance, not just visibility.

The Bottom Line
CPM is just one small piece of the puzzle. A great campaign isn’t built on how cheaply you can buy impressions; it’s built on how effectively you can drive action. We don’t waste time chasing vanity metrics. We build campaigns that get results.
