Facebook continues to lose traction among teenagers, according to RTT News. The teenage audience has been migrating to other apps, and the the trend continues according to the latest numbers.

A recent survey conducted by Magid Social Media indicates that a large number of teens, between the ages of 13 and 17 years old, have left Facebook and Twitter in favor of other social sites. Instagram, Pinterest and Snapchat have apparently gained these viewers, offering more interactivity in terms of posting pictures and having more avid conversations.

Facebook dropped to 88 percent in teenage use, a drop from last year’s 94 percent. As far as why they may have left the service, some believe it is due to the fact that their parents and relatives can see their posts all too easily, while other sites offer a bit more security.

The real concern for Facebook is that advertisers may begin to look at other social media in order to reach teenagers. The shift may be small in numbers right now, but part of the issue is the cool factor. Is Facebook losing the thought leaders and influencers among teenagers That could be a signal to certain brands that other social media is the right place to be. That’s something both Facebook and different brands will be paying attention to in the future.

Expect leading brands to keep an eye on what teens are getting into as far as social sites go – and where the staff of such sites go in terms of offering features to perhaps bring them back…
