AUSTRALIANS are sharing more content online than ever before as their engagement with social networking sites continues to grow, according to a survey.

We are also becoming increasingly engaged with brands, companies and government organisations through social media, according to the Nielsen 2010 Social Media Report, released this week.

According to the survey, 9 million Australians interacted on social networking sites in 2009; more than 7 million created a profile on a social networking site; and more than 8 million read a blog.

Online Australians’ engagement with companies grew significantly: more than 5 million people interacted with brands or organisations though social media sites such as Facebook and Twitter; 9 million watched an online video about a product or service they were considering; and nearly 4 1/2 million discussed products and services online.

The report found that Facebook was the dominant social media platform, with three-quarters of online Australians visiting the site; nearly 60 per cent having a Facebook profile; and more than a third saying they interact with others through social media every day.

An online survey conducted by magazine publisher ACP, released yesterday, confirmed the Nielsen findings. In the survey of nearly 800 women, 38 per cent said they had posted photos of babies or grandchildren on a social networking site. One in four said they had posted an ultrasound image and 4 per cent had used social networking to announce their pregnancy.

The Nielsen report also found a 400 per cent increase in the number of Australians visiting the Twitter site in 2009.
