And there is one method, before which it was really possible to get rich, but now this is impossible, since advertising services have become smarter and will simply block you.
The method is that it creates an Internet site with only one purpose — to place ads and earn ad money.
The sites do not contain useful information, their creation takes more than an hour of time.
The essence of the earnings is that the site will contain advertising blocks of the same advertising service, and visitors to the site are provided through the purchase of advertising on another service. And thus was carried out a quick money.
Now, this method is against the rules of advertising services and you just will cover.
Even if there is a way to earn some kind of loophole, I still recommend you do not use this dishonest earnings. Now there are other ways to earn, much more interesting and which benefit people.
