Doing keyword research is a tedious process. But because of the rewards we are able to get from doing proper keywords research, it is always worth it to find niche keywords to use in our marketing effort.

There are a lot of websites out there that offers niche keywords for a price. And a lot of people actually pays to get the keywords because the potential returns is worth it.
Here, i attempt to share niche keywords that i found. For free. As of everything, there is usually a catch. Please link back to my site if you think the keywords are useful. Cheers!
