First of all, before you vote to close it, read the next sentence. I do think this thread can be useful, because as we all know, in SO (StackOverflow) meets people who can implement project by themselves and run the website without any others' help and investments.
So, my question, how can you advertise your idea the best if you do not have money or have very little amount of it?
In my case, I dreamt about one idea last night and I can't find any of the similar websites on the internet and I really think it can be something unique and profitable. But I am teenager, I have no money and my parents definitely won't give me any. So, what can I do? Should I just advertise it through forums, facebook and etc. and expect luck? I really believe in this idea and I want to think about everything before I launch it. By the way, it is for 16-30 years old audience.
Thank you very much.
I tried to post topics in other websites, but got very few advices...)
