Niche Keywords
Niche keywords is where all the money at. Not just one niche keyword, you'll need a lot. If you had a list of 1000 good niche keywords, they can consistently bring in a constant flow of cash. To find these keywords, think of something common, such as music. Then break it down to maybe hiphop music and rock music, etc. You can then break that down to rock music cds or rock music albums. You can keep doing this and come up with a long list that should rank well in search engines since its a very specific keyword. They might get a visitor every couple days so if you have 1000, that could mean 1000 visitors a day. They key to these keywords is quantity.
