Don't know where to start

So I have been reading the forums for the last few days and I've come to a conclusion the a good way of legitimate and long term way of making money online is to make an authority website and and use SEO to rank to number 1 and use AdSense to gain money from it.

I am stuck on what part though. Where to start. I have no idea what niche or what keyword to try to rank to number 1.

Also since I am only 16, I was thinking if this AdSense and making websites don't work, I would use a mix of other methods to make money.
Currently I am making 200$ on ShareCash but I am thinking of starting various other ways including:
Promoting products on Clickbank with articles on articlebase
Putting up videos of new music on YouTube and locking the content
Putting trailers on Torrents and locking the content

I don't know which path I should take I have about 80$ to invest!

Any help would be appreciated!

okey, you gotta do a research on a keyword
1). Go to google adwords tool and see how many searches/month your keywords have
2). pick few (related or similar) for your website
3). Get hosting
4). Get domain (EMD - exact match domain is preferred)
5). Build a website or a blog
6). Do onsite SEO and put adsense on
7). Do offsite seo with backlinks and such
8). Do not stop adding content to your website (add at least an article a day)

thats it

You should download a keyword research tool like traffic travis (it's free) or you can get the professional version on this forum.

It will help you see how good a keyword is in terms of competition to commercial value...
