I found this to be informative. I will use this to refer to when working on SEO for clients: http://bit.ly/m6oVxc
The 7 SEO Myths That Just Won’t Die as paraphrased by me: 1. Linking to Google doesn’t help. 2. Keywords in the meta keyword tag don’t have any bearing on rank for those words. 3. Submitting to search engines isn’t useful. They find pages by following links. 4. Title tag is useful, keywords within a link title attribute, not so much. 5. Keyword domain redirection is not a good idea. 6. Ads don’t help if relied on for links since they are usually JavaScript. 7. Small changes to content is not fresh content.
