My favorite style in this is article marketing. You create anchor content on your website or blog, then you build authority-content links to that content, effectively driving up the visibility. I've used this single strategy to rank hundreds of keywords in the #1 spot on Google, and I would highly recommend that if you're going to learn any marketing strategy, that you get really good at this one.
It’s one of the oldest and most proven ways to make money – buy low, sell high. The buy low part comes from searching garage sales, estate sales, and even thrift stores to find items that are in good condition (“gently used”) but selling well below what they would if they were brand-new. In this way, you might be able to acquire an item for $5, and later sell it for $50.
Once you’ve had children, many parents find themselves caught in the trap of needing to work but wanting to stay home with their kids. Creating your own parenting blog can not only be a way to make some money, but it can also help you connect with other parents and make sense of those crazy sleepless early parenting years (it does get easier don’t worry!)
