I am working on a micro site and im going after the 2nd biggest keyword in my micro niche, im currently on page 2 for it. It gets around 300K searches broad and around 50K exact per month. However while doing some research I found out that im ranking on page 2 for a similar keyword. Now this similar keyword get around 2.5 million searches broad, but only 6K exact. My question is: If I can work on this "similar" keyword and I get my site to rank top 3 for the keyword should I expect to get a good % of the 2.5 million searches from the broad searches or will I only get traffic from the 6K exact. Many thanks friends.
