How do I effectively build a website that makes me money? ? -

How do you effectively build a website to make money? I m aware of buying the correct software and finding a hosting company, but how about all the other details? I am serious about making this work and am not sure if selling something is the way to go...I may just want to earn money from advertising. I ve got a specific topic that I want to fully exhaust on an informational basis and make money while doing so. Any tips, hints for success, past experiences are all welcome|::::|Setup a blog.
