First, read the English article below.

When you sign up for AdSense, you'll want to know what kind of revenue can you expect to see. There is a lot that goes into what kind of return you can expect, and managing those things will help you maximize your earning potential. First and foremost, in order to generate any kind of revenue from AdSense, you must have people clicking on your ads. In order for this to happen, you need to have people on your site, reading your content! Whether you have a business website or a personal blog, the rule is the same: Get the word out!  Heavily trafficked large sites can see over a million hits a day, whereas a blog might feel lucky if they have 100 visitors a day.

An ad that may generate $.03 per click may get 100 hits, but that doesn't add up to much. This is the percentage of visitors to your site compared to how many of them actually clicked on an ad. If 100 people came to your site, and 1 of them clicked an ad, your CTR is 1%, and that's not an unreasonable number. You can see how getting more traffic to your site will really make a difference. This is an estimate of how much you might receive if you have 1000 impressions (page views). If you made, for example, $1 for 100 impressions, your RPM would be $10. There is no guarantee you'll make that, but it's a good way to check the overall performance of your site. The quality of your content is an important factor in understanding your earning potential.
