The social networking site is also planning to make it easier for people to have their main news feed in a "chronological" order with the latest posts up first.
This model was ditched back in 2009, with the company preferring to use algorithms to rank the content.
However, Facebook's vice-president Nick Clegg acknowledged a lack of transparency and information which had led to users not trusting the feed.
Now, the 'most recent' option has been moved to a new 'feed filter bar' which can be found at the top of news feeds.
As introduced in October, Facebook will also let people to prioritise friends' posts - up to 30 users - before the algorithm takes over.
Meanwhile, the "Why am I seeing this?" links will now add further transparency by detailing the criteria for recommended posts.
Clegg commented: "Content ranking is a dynamic partnership between people and algorithms.
"Your news feed is shaped heavily by your choices and actions."
