Google has again rolled out another Panda update. This makes Version 20, and will apparently effect around 2.4% of all English search queries. The latest Panda update comes around the time of the exact match domain update, so for those negatively impacted by the update, it may be a little difficult to know which update was the cause. As the update focuses around quality, if you feel you've been hit by this update, it's time to review your website and look at ways to improve its quality. A number of factors determine quality. Arguably the number one is content. Content should be unique, well structured and useful to your market. And of course it should be easy to reach to in your site. A lot of other factors come into play to making a quality site for Google (as well as your target market), but providing you have a proper SEO strategyin place this should be no problems.
