Last night I was looking to build out some keywords lists, and I remembered about a few cool tools for developing and building out keyword lists.

One is called spyfu.

Spyfu gives you the ability to review your competitors keywords, what they are focusing on and what they are using successfully (this requires a little homework).

Another is called Keyword Spy

Keyword Spy’s services is similar to spyfu, although they offer greater reporting and a little less data than spyfu.

Once you have compiled your keywords, if your looking to go deeper, you can use a keyword combiner like adwords generator

Just a few basic tips for keyword discovery and manipulation.
