Women prefer blogs and Facebook to Twitter; they are also losing interest in traditional media according to Jason Lee Miller of WebProNews.

Women keep their personal lives and business lives very separate when it comes to social media, according to the 2009 Women in Social Media Study by BlogHer, iVillage, and Compass Partners. While women consider blogs great sources of information, especially regarding purchases, the vast majority of women use social networks solely for keeping in touch with family and friends.

Over half (55%) of the women surveyed in said they participate in some kind of blog activity (publishing, posting comments, reading), and 53%use social networks.

But here’s the kicker: Women use social networks in the purest sense only; 75% use them to keep in touch with friends and family, and not so much as information sources or for making purchase decisions. That’s a major insight considering this is the half of population making 85% of purchase decisions in the US.

In contrast, women rely more on blogs for the business of life, and are twice as likely to use blogs rather than social networks as an information source (64%), for advice and recommendations (43%), and opinion sharing (55%). Women are 50% more likely to use social networks merely as a means of keeping in touch.

If women prefer blogs and Facebook to Twitter, how does this impact your market strategy?
