After testing out Twitter-style trending topics since August, Facebook finally rolls out today its own version of the feature, simply named "Trending."

Facebook's engineering manager Chris Stuhar announced the launch of this feature through the site's official blog.

"Today we're announcing Trending, a new product that's designed to surface interesting and relevant conversations in order to help you discover the best content from all across Facebook," Struhar writes.

The section will feature a list of trending topics customized for every Facebook user, and will be shown at the site's web homepage in the U.S., UK, Canada, India and Australia. Each listed trend will include a short description, and users can click on the link to show posts and content related to the topic. However, the user cannot filter the trending topics manually.

But unlike other trend-listing sites, Facebook uses an algorithm which recognizes topics which has recently spiked in popularity. And instead of listing down trends by words or phrases, Facebook's Trending section lists down trends by headlines.

Techcrunch explains the feature this way:

Facebook's version of Trending doesn't just list "24″, it explains that "Fox Sets May 5 Premiere for '24: Live Another Day'". While you might know Cristiano Ronaldo is a famous soccer player, if he trends on Facebook, it'll tell you why, such as "Cristiano Ronaldo wins Fifa Ballon d'Or after stellar year at Real Madrid".

Websites like Techcrunch observe that the move is done following the stiff competition with microblogging site Twitter, along with its desire to become a reputable news source.

Facebook's Trending section does not feature sponsored or promoted trends as of the moment, but Mashable notes that "there seems to be ample opportunity for doing so in the future."

Facebook is currently testing out a version of Trending section for mobile applications, and once it is fully developed, it will be rolled out to different platforms.
