really awesome article. I have been doing some of those things instinctively going after LTK and MTK. The ones with high search volumes are really difficult to rank for. If you use the Keyword planner tool by google it shows the difficulty of such keywords. Another thing i like about your post which is kind of weird is the length of time it took. I have been blogging on my site about 11 months. So for others they shouldn't be discouraged if they don't see immediate results.
