I've been using keyword research pro that really rocks for keyword research & finding niche keywords. This program can search these sites. - Google AdWords Keyword Tool - Keyword Discovery - Wordtracker - 7Search - Miva - YouTube - Ask.com It also shows the pay per click bids & allows you to save the file as a excel spreadsheet. I'm thinking of selling some of these keyword & ppc list by emailing website owners who are down in the serps for their niche. Anyone do this & have success with it. I would be emailing them directly which is considered spam. If I register a domain & email them It would most likely get shut down for spaming. To test the market I was thinking of taking a screen shot of the spreadsheet and post the pic on some web 2.0 site like blogger & email them.
