Hi Guys, Sorry if this has already been asked but believe me, I've tried to search both the forum and google but struggled. Basically I'm looking for the most comprehensive guide to keyword research. Up until now,I've paid for these services to allow me to create niche sites but it's proving to be quite costly now. I don't mind paying for a guide and software but want something that will produce keywords and show me the low competition keywords and whether people are actually bidding them. Thanks Guys!
