Twitter, YouTube, Facebook And Foursquare: Social Media Marketing By The Numbers [INFOGRAPHIC]

If you’re a social media marketer, you’ve got to love numbers. Statistics, growth charts, engagement rates, they’re all great for wow-ing clients.

Some of the best numbers are those that come from the top marketing campaigns online. This infographic made for Mashable tells the tale of some of the most successful social media marketing campaigns to date, and the number of Promoted Trend impressions, clicks and retweets these campaigns have garnered will impress the socks off of any client.

This infographic shows the power of social media, so you can assert its importance to a wary client.

For instance, it illuminates the top Promoted Trend campaign, a Coca-Cola sponsored promoted trend that accumulated an impressive 86.5 million impressions. That’s 86.5 million impressions for a single promoted hashtag on Twitter.

American Airlines also saw some serious success on Twitter. Their “Tweet to win 30k miles” campaign earned them 18,000 clicks. And IBM’s hashtag #LS11 for its “Lotusphere” conference appeared in 35,000 tweets.

Of course, Twitter isn’t the only social network featured in this infographic, and it isn’t the only social network you should focus on when running a social media marketing campaign.
