OK, this is probably going to be a really question to answer, basically I need a yes or no answer from people who know about domains/keywords and making money from sites.
I have an existing site about Ronda. And on this site I have a learn English page for local students. But I need to start producing podcast homework for them, and I'd like to make the podcasts available to other people to download along with my lesson plans. The other people who download them will most likely be other English students rather than students.
Should I start a new site with a new keyword rich domain? In a perfect world I'd like to make money from the podcasts, perhaps using AdSense on the site.
