CPM
Le CPM est le prix pour mille vues d'une publicité. Des mots simples, pourquoi c'est important, et un exemple concret du monde de la publicité.
Réponse courte
Le CPM est le prix pour mille vues d'une publicité. Il vous permet de comparer équitablement une grande newsletter avec une petite, car les deux sont tarifées pour mille personnes atteintes. Une newsletter qui facture deux cents euros et atteint quarante mille lecteurs a un CPM de cinq euros.
In one sentence
CPM means the price for one thousand views of an advert. It lets you compare a big newsletter with a small one fairly, because both are priced per thousand people reached.
A real example
A newsletter that charges two hundred euros and reaches forty thousand readers has a CPM of five euros.
How CPM works on Advoratise
Most sellers here do not quote a CPM at all. They quote a flat price for one slot in one send, one episode or one week, and they state the audience size next to it. You divide one by the other and you have the CPM yourself, from two numbers that are both on the listing. That is deliberate: a quoted CPM hides whether the audience number was ever checked, and a flat price plus a stated audience does not.
The mistake people make
Comparing a CPM against one from an ad network. A network CPM usually counts machine-served impressions, many of which were never on screen; a newsletter CPM counts people who were sent the issue. The second number is smaller and worth far more. Compare CPM only against the same kind of inventory.
What to look at next
Every listing shows its price in euros and its audience size, so you can work the CPM out yourself before you book.
Questions fréquentes
- Why do Advoratise listings not show a CPM?
- Because the flat price and the audience size are both shown, and those two are checkable. A CPM on its own is not — it can be made to look good by inflating the audience it is divided by.
- Le CPM est-il le même partout ?
- L'idée est la même, mais le comptage non. Vérifiez toujours comment une plateforme le compte avant de comparer deux chiffres.
- Dois-je comprendre cela pour utiliser Advoratise ?
- Non. Chaque page s'explique avec des mots simples, et ce glossaire n'est là que si vous voulez les détails.
