I get surprised when I want to optimize any keywords, on mostly keywords about.com and wikipedia are coming first, so I want to know that how much effort would I have to make, and what type of technical efficiency should I have?
I would say a lot, however targeting the keyword in the domain and title of your sites homepage could do A LOT for you as well. Use a "niche analyzer" to judge the difficulty. No one does their own research manually these days
