Google strikes again! However Good SEO practices will always ring true for those who were unaffected. Here’s a handy Audit guide you can go through and make sure the common sense SEO applies to your website:
Web Browser Test
See the way Google see’s your pages. Disable your java script and cookies, and test to see that your content is relevant and not hiding anything… Google webmaster tools also has a handy back-end to assist you determining any such issues.
Do you trust your own website? Look at it from the visitor’s point of view. Check for any duplicitous content, and make sure the first impression counts.
Global Navigation and Broken Links
Are any links broken? How many clicks does a visitor have to engage to find the content they want? Do all navigational menus serve a real purpose or are they in any way put there just to add more H2 headers than necessary ( an example of this would be over optimization by including all zip codes of your service provision).

Optimized Web Content
Make sure you are optimizing each page by the correct meta tags, rich snippets, and micro data where possible. Once again don’t over do it, is it readable to the average user or is it suffering a glut of keywords stuffed into awkward sentences and titles.
Are you being linked to from bad neighborhoods? Do you have authoritative sites linking back to you talking about relevant and useful content? Penguin is really cracking down here in it’s hunt for comment spamming from low quality sites. Make sure you aren’t taken down by this.
