First you have to make sure your website does not have poor quality back links. For that you can check your website back links by searching for link:yourdomain.com in Google. Links coming from spam websites and parked domains should be removed. To remove such back links you can directly contact their administrator. Once you remove all such back links submit reconsideration request for your website. Thanks.
