Its good presentation, But it has lot more to explain how all the things are working,
Today, SEO as well SMO are both important for business promotion but the mot important thing is that what we are presenting and what media we are targeting. In more clear words, who are our customers and in what manner we are presenting the things, like it may be a Advertisement banner, a story board, a presentation, an interview, a case study or anything else.
Eg: If i am dealing in heavy miniseries then Facebook and Twitter will not work for me. I have to focus on those media from which i could get interested visitors.
SMO is very helpful in promoting Consumer Goods, because it provide a good platform to express views.
