The Golden Egg Is Ad Arbitrage
Buy Redirect Traffic for a Ridiculously Low Price to Sell at a Higher Price Through Ads
When you sell ad space off your web pages you will know the ad networks value your web space by traffic initially and later, once they compile enough data, conversions.
When you have a landing page that's optimized to earn you money from every visitor who exits the page by either clicking an ad, subscribing to your blog, or following you on Facebook (for later gains).
When the only way off your landing page without earning you money is by closing the browser or hitting the back button.
Imagine what one hundred thousand visitors wanting to leave your page are going to earn you in profit if you are only paying one cent each to get them to land.
