Keyword research is one of the cornerstone's of starting any good search engine optimization campaign. While I use Wordze for all my keyword research, I started my adventures as an SEO with a fair number of freely available keyword research tools. Each of these are slightly different from the other, and when used in combination, they can provide a potent starting point for your SEO campaign.
