Saw this at Code: http://www.business2community.com/seo/googles-over-optimization-penalty-how-to-avoid-it-and-how-to-fix-it-0166538 I am just going to go over a few good and important points here: 1. Excessive keyword density ? A keyword density of 2-3% should help in not raising any flags. 2. Strictly keyword-rich internal links ? Linking to your website internally with your keywords is another issue Google has been targeting. Linking to other authority websites such as Wikipedia with your keywords is advisable. 3. Ugly site design ? A good looking, user-friendly website is recommended rather than using the same theme across all your websites. 4. Weak content ? Wasn't this obvious? 5. Few or zero value propositions ? High bounce rate in other words. Keeping your bounce rate low should help in letting Google know that users like your website 6. Domain name is keyword ? Still looking for EMD's? I guess not! 7. Excessive back-linking ? Using the same anchor text everywhere won't help increase your rankings anymore. In fact, it will get you a penalty. So it is wise to use Google's keyword tool to search for related keywords as well as use click here type backlinks and simply your domain name as an anchor. 8. Excessive H1 tags ? If your website is a static one then using only one H1 tag is advisable. Please add your own points as well. It will make everyone's SEO more simpler.
