lets assume, I have a article that is ranked well (but not top) in search engine. Now, If I want to modify it a little more optimized, will the modification hurt on existing ranking in any ways? Thanks.
Modifying Article - Effect On SEO

It seems you are asking about putting more keywords in the article. We know from the latest Google Panda and Penguin updates, keywords in an article is least important. If due to certain modifications in the article a user spends more time with the article or even if due to some of the links (internal/external) you have put in the article which is relevant to your article and as a result users spend more time than usual, is a plus for you If you have modified the site in such a way that user tends to perform Call To Action on the site, then the Google sees and considers the article helpful to users and so Google will increase the ranking as well as the position of the article.I will again say Keywords in the site is of least importance, now-a-days SEO is all about user experience with the website.
