Google AdSense is the best and easy way to get earning with your website by displaying ads. But there is not a single type of website that every one have. Different peoples have made their websites on different topics and with different ways. For example, some people have websites on which they publish articles or stories, so visitors can come and read them. Some people have forums in which they got members which discuss their problems and thoughts.

Most of the peoples have joined Google AdSense as a basic earning point. And most of them are asking why they are not earning on their expectations, although they have the huge number of visitors and page impressions. To give them the answer, i will say they have not joined a best advertisement network for their kind of website. Let me explain it all.

A little introduction of CPM and PPC ads

Mostly there are two types of ads which different network offers.

1. PPC or CPC Ads : These types of ads will give you $$ whenever a visitor of your website clicks on it. You will not get any benifit of these ads if your visitors does not click on it. As the name says these are Pay Per Click or Cost Per Click ads. AdSense Ads are the best example of CPC ads.
2. CPM Ads: These types of ads does not require a visitor to click on them or not. They will give you revenue for every 1000 impression of these ads. The word CPM is “Cost Per 1000 Impressions“. There are many networks which provides CPM ads.

What is the right kind for your website. CPM or CPC

This is the reason which most people want to know, that why they are not earning much even they have a lot of traffic. Lets make an example of my website
I have a website on which i am publishing articles and i have joined AdSense and displaying their ads. I am getting much visitors and clicks, of course a lot of $$. I am getting clicks because my visitors come here to read some type of information from an article. They can click on my ads when they will find some better titles of these ads. Because adsense shows the relevant ads from content, so it works best for me.

But if i would have a forum, on which i have no article just the posts of different peoples. And all of my members are sharing their thoughts and problems, no one will want to leave the forum by clicking an ad. I may got some clicks but not very much. So i will not consider the AdSense ads as a best choice for my forum. I will put the CPM ads there because i have a huge number of daily page visits and i can earn a lot more than AdSense by using CPM ads on my forum.

Another example of site is a gaming site. Suppose i have a website with many free online games. Then CPM will again a best choice of this type of website. Because CPM ads have high rate of gaming related ads. People will come to play the games and i will get earned no matter if anyone have clicked on an ad or not.
