Here's an idea...Compete against yourself.
If you've had a look around this blog, you'll know that I have a few different websites and blogs in the same niches. I started to do this so that I would be able conduct different experiments on different sites, then IF it worked, I would apply the same technique to the other sites.
But have a little think about this. It didn't take me very long to figure out what would happen if I had five different sites targeting the same keywords.
So let me plant a seed in you head, but know that I expect you to do the watering...
What if you used a proxy...and set up some "pen names"?
Then used those pen names to register some new domain names?
To build a new site? To target the same niche, same keywords and promote similar products?
What if you built a couple of hundred backlinks to each site?
What if you owned half of the first page of Google??
Icing...or the cake? This is the cake!
Stay tuned, you've got a whole month of ONE thing(s) to consider, this is just the first and trust me, they get better!
