How I can use various social media marketing platforms for promoting my business??
you should try to find people who like your products and then join similar groups. update your social friends about your product and business.
Sorry, but this is far too vague a question, and as you can see from the answers you've received, a simple search would have sufficed to answer the question. Please search (both the forums and via your favorite search engine), and if you've still got SPECIFIC questions, please feel free to repost.
In the meantime, THREAD CLOSED.
