If you were to sum up marketing in 2013 in a few words, social marketing would most likely feature on your list. And for a good reason, too. Social sites are closely linked to content marketing – another very hot marketing topic – so, naturally, marketers looked to the likes of Facebook, Twitter and Pinterest to help them reach their target audiences.

Let´s take a look at some interesting statistics that show what happened within social media last year. According to an infographic I came across published by Page Traffic Buzz, last year was quite eventful. Google+ tried to make up for its slow start in previous years and succeeded; figures show that it´s now the second-largest network. Over the past 12 months, there was an average of 25,000 new users per day – around eight users per second.

Twitter was busy in 2013, too. It now has more than 230 million active users per month, spending about 170 minutes on the site every month. However, only half of these users actually produce content, while the remainder only read tweets. The best part of last year for Twitter, without any doubt, was the great success of its Vine service. A branded Vine video is four times more likely to be seen that a regular branded video, the infographic noted.

Meanwhile, Facebook continues to dominate the social media world. In 2013, a staggering 95% of its users logged on at least once per day. The social network accounts for around one in every six minutes spent online, statistics showed.

Is there anything you would add to this list, in terms of social media evolvement over the past year?
