Niche Affiliate Marketing
Niche Affiliate Marketing in simple terms is marketing to a subset or sub-subset of a primary market. The focus of your Niche Affiliate Marketing efforts should be to go after high value, low competition keywords with at least 400 monthly searches.
When starting out with niche affiliate marketing it is easy to get caught up in the keyword numbers game and use a broad keyword that gets tens of thousands of monthly searches. However, the competition is often too high for these search terms and it would take forever to out rank them. If you pay attention to trends or research terms you are familiar with this can help you get into the game.
