Step 1: Make a blog or a web page like this one here.
Tips: Make it interesting and eye-catching! Making free $$$ on youtube is pretty eye catching right? Also, load it with good info, no lies or scams, and spell words correctly. Make it look professional (mine's lacking slightly).
Step 2: Create what's called Google AdSense .
This is what will bring you your income! Google is a legitimate site and there's absolutely no way to get scammed by them. Just don't lie about who you are or your address. They need this information to be able to send you your checks! That's right, your checks! The one's that you can cash and spend on whatever you like! Alright I think you get the point.
How all this connects: When you use Google Adsense to put ads on your blog, go to youtube. As you watch videos and laugh put the link for your blog in the comments of the videos. This should attract people to YOUR blog. Out of those people some are bound to click the google adds on your page. For every click you get cash. Easy as pie!
So if you found this helpful why don't you go ahead and click some of the adds on my page! Go ahead, it's free for you and it's the least you could do :)
