Google algorithm changed and it called penguin update. And it definitely affect on seo. If you violet google webmaster guidelines then it's not good. Now a day google has been really very strict to terms and conditions. If you are doing lots of linking through forum, blog, article submission, directory submission to gain ranking very fast means this update relates to over optimization of sites. Follow google webmaster guidelines for your website.
