Take Care of Keyword Density & External Links
Keyword density is now very important in order to be on safe side from Penguin, you'll need to have a maximum of 3% keyword density for your articles. Means if you wrote an article of 500 words then make sure you use the main keyword just 15 times, else use synchronous. Moreover, take care of your links which are going outside from your website, those links should always be added a rel=nofollow or rel=external nofollowattribute, so that Google Penguin can't affect you.
Work more for the users
