SEO is so broken, it's not about website content or website quality. It's about how much money you pay to some punks - "SEO experts" who are hacking a system. I'm so sick of that.
This is not how it generally works, I would say. It is more about how much you pay Google and how good your page is. I worked with several SEO experts and none of them suggested scams like this. The risk of doing something like this is too high for many companies.
