Another big lesson I’ve learned is to go deep when you’re trying to reach an audience or develop a platform. One way to build a really profitable course is a strategy I’ve developed called “the 4-deep technique.” This technique asks you to niche down at least four levels until you’re really at the source of someone’s problem. Start with the pain then come up with a solution. If you want to create a successful product, it needs to be a pain reliever or something that solves someone’s problem in a way nothing else can.
2. InboxDollars – InboxDollars is similar to Swagbucks, since you’re going to be taking surveys, shopping, etc., so if you want to maximize your return, sign up with both websites. They also offer a search engine that pays you (like Swagbucks) and you get $5 just for signing up.  I won’t continue to list survey sites one after another down the list, but if you want to get paid to take surveys, also check out GlobalTestMarket, E-Poll Surveys and Survey Club.
Now this would usually be considered a risky or "blackhat" link building method that could get your websites penalized by Google. However, we aren't building the links directly to your main "money websites," we are building the links to your support layer of websites! This includes article directories, web 2.0 properties, and mini blogs that you've already created (taught in the prior lessons).
