You've probably heard about this way of making money on the Internet, as creating your own website.
In the ideal picture, a site is a display ad platform that advertisers pay you to place. In order for someone to want to place an advertisement on your site, the site must have a certain audience reach, look presentable, and the advertisement must correspond to the main topic of the page. In order to achieve all this, you need to spend a lot of effort and money on the "promotion" of the site: contextual advertising, interesting topics, regular content filling.
Are there any easier options?
There is. For example: creating a website for a referral link for an affiliate program. Thus, you can "kill two birds with one stone": with proper self-promotion of the partner company, you just have to send a link to your own site to a potential audience and all "recruits" will automatically be included in your team. That is, the growth of the audience on your site will be as organic as possible, while requiring the minimum amount of your resources, and the referral link at this time will do its "monetary" business for you.
