What Is CPM?
Quick Answer
CPM (Cost Per Mille, or cost per thousand) is an advertising pricing model where you pay a fixed amount for every 1,000 times your ad is shown — regardless of whether anyone clicks it. It's used mainly for brand awareness campaigns where visibility, not clicks, is the goal.
Also known as: Cost Per Mille, Cost Per Thousand
What Does CPM Stand For?
CPM stands for Cost Per Mille — "mille" being Latin for thousand, so it means cost per thousand ad impressions.
CPM vs. CPC — What's the Difference?
| CPM | CPC | |
|---|---|---|
| You pay for | Every 1,000 ad views | Every click |
| Best for | Brand awareness | Direct response (leads, sales) |
| Risk | Pay even with zero clicks | Pay nothing until someone clicks |
Why Does CPM Matter for a Small Business?
- It's the right model when the goal is being seen, not clicked — e.g. building name recognition in a local area.
- It's usually a poor fit for a small budget aimed at generating leads or sales directly — CPC is typically the better tool for that.
How Is CPM Calculated?
CPM = (Total Cost ÷ Total Impressions) × 1,000. If you spend £50 to get 10,000 impressions, your CPM is £5.
Key Takeaways
- CPM charges per 1,000 ad views, not per click.
- It suits brand-awareness goals, not direct lead generation.
- A low CPM doesn't guarantee good results — check it alongside conversion data.

Frequently Asked Questions
What's a good CPM?
It varies hugely by platform and audience, typically ranging from a few pounds to £15+ depending on how competitive the audience is — there's no single universal benchmark.
Is CPM or CPC better for a small business?
For most small businesses focused on getting leads or sales, CPC is the better fit since you only pay when someone actually engages. CPM suits awareness-first goals.
Does a low CPM mean my ad is performing well?
Not necessarily — a low CPM just means impressions are cheap. It says nothing about whether those impressions are leading to clicks or sales.
