Target CPM stands for “Target Cost Per Thousand Impressions.” It’s like a special rule that helps people who show ads on their websites (called publishers) decide the minimum price they want for showing ads. Imagine you’re selling lemonade, and you decide that the least amount of money you’re willing to take for a glass is $2. Target CPM is a bit like that but for ads!

Why Do We Need Target CPM?

Sometimes, publishers might set their prices too low because they’re afraid of not selling enough. This means they might not make as much money as they could. Target CPM is like a superhero for publishers – it helps them sell their ad spaces for the best price, so they make more money!

Setting Up Target CPM

Publishers can use Target CPM when they’re setting up new ads, or they can add it to ads they already have. It’s a bit like deciding the price tag for items in a store. The good thing about Target CPM is that it can change the price tag automatically based on how many people want to buy the ad space.

Is Target CPM Right for Everyone?

Well, not necessarily. While Target CPM can help increase the number of ads shown (which is called the fill rate), it might not be the perfect choice for everyone. It’s like choosing toppings for a pizza – some people like pepperoni, while others might prefer mushrooms. Publishers should try it out and see if it works for them.

Target CPM vs. Manual CPM

Here’s a quick method to recall the distinction:

– Manual CPM is equivalent to charging a fixed price for your lemonade, such as $2 a glass. Target CPM, on the other hand, is analogous to altering the price of your lemonade based on how many people want to purchase it. If there are a lot of people who want it, you might charge a little extra.


That’s all there is to it! Target CPM is a useful function in Google Ad Manager that assists publishers in making more money from their advertisements. It’s similar to having an ad price system that varies based on demand. Just keep in mind that you should experiment to determine what works best for you.
