One rule you can always follow in regards to making sites and driving traffic to them is - CONTENT IS KING. There will be nothing else in this world that will drive traffic as much as good content does. Nothing will attract more customers and visitors. Doesn’t matter what your niche is - as long as your content is good, you will see an audience that will grow exponentially.

In my case it’s child development research into play tips for parents. I can already see that the outcome of my experiment is going to be the same as yours. Great content but who cares. I hadn’t even thought about my key influences. I know some important ones, but don’t see how they would share my content. I thought I was writing content for my potential customers.
