What is CPM?

Cost per mille (CPM) is a method of calculating the ad buying price. It is the amount to be paid as an advertiser for every 1,000 readers his ad reaches. This method is also used in radio or TV advertising. CPM is the most common way of estimating ad costs and qua invoice.

What is CPM advertising?

Cost per mille, abbreviated as CPM, is a method for calculating the purchase price of ads. It is the amount to be paid if the advertiser reaches every 1,000 readers with his ad. CPM is the most common way to estimate ad costs and in terms of billing.

How do you calculate CPM?

CPM is based on impressions, not clicks. The publisher (website owner) and advertiser set a price per 1,000 impressions. Let's say an advertiser sets a CPM of €10 and your website gets 1,000 impressions. The advertiser pays you €10. If a website gets 1,000 impressions and 10 people click on the ad, the ad revenue is €1. If 1,000 people click on the ad, the revenue is €10. When you set up an ad, you can usually see the CPM. If you don't see it, ask the advertiser.

What is eCPM?

eCPM is the expected cost per mille, or cost per thousand impressions. The eCPM is the average amount an advertiser pays to have an ad seen 1,000 times. The eCPM is calculated by multiplying the average amount an advertiser pays per click by 1,000. For example, if an advertiser pays €0.50 per click, then their eCPM would be €0.50 x 1,000 = €500. The eCPM is useful in determining how much you can charge for ads on your site, or how much an ad network should pay you for your ad space.

Why is CPM usage in digital advertising so important?

CPM is one of the most common ways of measuring ad value. The unit is most commonly used for pricing banner ads (although it can be used for other ad types as well). CPM pricing is usually determined by supply and demand. The more demand for ad space on a site, the higher the CPM rate. The more supply of ad space on a site, the lower the CPM rate. CPM rates for digital ads are usually significantly lower than rates for other forms of media such as radio, TV or print. This is largely due to the fact that it is much harder to track how many people actually see a digital ad.

There are several challenges in using CPM to set ad rates.

Digital content manager Peugeot

Whether it's about content or technical adjustments, it doesn't matter. Martijn briefs this in a very clear way so that it can be implemented locally or by our head office in France. [...] Since the start of our collaboration, we have achieved great results. Keep it up!

Marien van Stegeren

Eigenaar Kitcentrum

When your online onder venture grows, expectations often grow too, in every area. To a large extent, we were in control of SEO and its interpretation ourselves. We found out that our own "general view" was no longer sufficient, so we engaged Bureau Onder. Surprising and clear. We have built up a fine collaboration, partly because Martijn also regularly visits our office with Eline or Mariska (depending on the case), which is very valuable to us!

Marten Stellingwerf


Martijn and Mariska make the SEO story understandable for the layman and are happy to think along with us. It is nice that there is a personal contact moment every month with an extensive report and the opportunity to talk everything through. After just a few months, Onder has already managed to achieve number 1 positions on Google with some of our webshop pages. We are very satisfied with Onder.

They speak our language: don't nag, get down to business. That is what we love!
