Potential Facebook additions may benefit both users and businesses

Facebook developers are once again tinkering with their site. Search Engine Watch reports that new additions to the site may include an option to view all news feed posts, and certain mood buttons in addition to "Like."

According to the news source, users currently don't see every Facebook post on their news feed. The website only shows content it thinks is the most relevant based on factors such as how recent the post was written and how much activity its seen.

Posts that are typically filtered out include excessively "liked" pages those from users who update too frequently. The modified version would allow more posts to be seen.

"We are currently testing a feature within News Feed that gives people the ability to see what their friends are commenting on and 'liking,'" a Facebook spokesperson told the news source.

The Wall Street Journal adds that many marketers and third-party developers will have a chance to stand out more in the news feed with the possible addition of re-posting. This could act on a similar capcity to Twitter's re-tweet button, and provide companies with more ways to optimize their pages.

A "dislike" button may also be in the works, the news source adds.
