is this right to create few more site related to your main site and do black hat SEO for other sites related to main site and promote your main site from those BLACK HAT SEO SITES ?
Sorry But why do blackHat do white Hat SEO your supporting sites helps your business through WhiteHat techniques as well.
Why would you link from your blackhat sites to your main site? I mean it depends on what you are trying to do, but it doesn't make too much sense. What is your main site about (type of monetization)?
i am not going to do in black way, i was just wondering what people think about it, i am working hard on white ways but not getting much results
