HI,To all I know about SERP,SEO,SEM but SMM is the new word for me and how can we use SMM for Internet marketing ?
SMM is the optmization of website using social media sites like Twitter, Facebook, Digg, YouTube, StumbleUpon and etc.
Social Media Marketing, is marketing through sites in the above comment, it's nothing to do with SEO because your traffic is coming from social sites not search engines.
