People all over the World Wide Web are up in arms over the Google Penguin and Panda updates and the changes people are being forced to their marketing plans because of them. Even if you use pay per click advertising through Google, the updates are going to have an affect on you. The best way to get through the lower level hysteria and keep yourself from freaking out is to track down the right kind of information. From a broader perspective, you will probably be okay if you have been doing the right sorts of things. If your website is in need of revisions, revise things and then keep moving on.
