Search engine optimization and Internet marketing are two of the most competitive niche in the blogosphere. Inside the congested blogosphere, it is a serious achievement to make it to the top 20 blogs. Imagine the hundred of thousands weblogs competing against each other. Imagine your blog upstaging them all. It's a euphoric feeling you know.

Really, it is a combination of hard work and know-how. Okay, let me add in a dash of luck. There are instances that are beyond your control. So it is better make a little leeway.
