This is a 90k search keyword that I want to churn and burn. I have hear that there is now a waiting period for this churn and burn tactic. I have never used it before - only greyhat methods to rank my monesite. Now that I am pretty much happy with its position I decided to try out a churn and burn tactic. How many pages should I build on this churn and burn website? Is it possible to outrank Wikipedia with 700+ links for this keyword? Most news stories also outrank it easily. The question is - is it worth it to rank this keyword or should I carry on with my kw research?
