Keyword research is important in choosing your domain name, page and blog titles and content, and in SEO plugins. If I'm looking for keywords for content or titles, I look for popular keywords with little completion, but I don't ignore the rest of the keywords that come up. I place them in source boxes that ask for keywords.

When writing, avoid stuffing of keywords to avoid problems with the search engines. I put the keyword or phrase in the title, the first paragraph and the last paragraph. The old one percent theory doesn't hold anymore.

Suggestion: I use JAAXY which is the best keyword tool for affiliate marketers. I also use ubersuggest.org and Google suggest. Sometimes I look at meta files on competitive sites to see what keywords they are using.
