Can you expand more on that. She doesn't care what i do article, direcotry, blog comments etc. she just wants me to do everything for those 2-3 high competitive high traffic keywords instead of 10-20 low competitive low traffic keywords. I already explained why she thinks it would be good strategy to work for 2-3 keywords than 10-20.
If i go in general:
Do you think doing all that work for 2-3 keywords is a good strategy?
Is it possible that one can rank for high competitive keywords if huge quantity of quality links to site contains those keywords?
