I need you to write the following three social media relating articles. The style of the articles should be similar to what I would read on Mashable or similar websites. The length for each article should be around 1500 words.
Article 1: Facebook marketing. Why small and medium businesses should have a presence in Facebook, examples of good Facebook campaigns or pages, (examples Facebook campaigns or pages that have gone wrong). Should you buy Facebook likes or shares? (the answer is: no). How to get facebook likes and shares for your business or product? The Do's and Dont's.
Article 2: Twitter marketing. Similar to the first article, but this time about Twitter.
Article 3: Viral marketing. What does it mean when something goes viral on the social media? What are best recent examples of something going viral? Examples of marketing campaigns that have gone viral? What are the common factors in online marketing campaigns that have gone viral, that is, what does it take to have content go viral? Note: try not to mention Youtube too much, we all know about the funny cat videos on Youtube, but lets try to focus on something that has been going viral on Facebook and Twitter, and on things relating to products or businesses, not about funny videos or funny pics.
