The new service enables users to subscribe to the Facebook feeds of any writer or media source with one click without leaving a third-party website.
They will then receive all the public updates from that page on their Facebook news feed without having to be 'friends' with the publisher, in a service designed to increase the level of interaction between writers and their readers.
The Subscribe plug-in, which works in a similar way to Twitter's 'follow' button, was introduced in September, but is now available to place on any website.
In a blog post, Facebook's Stoyan Stefanov said: "We're launching the Subscribe button for websites, a social plugin any site can add to give visitors the option to subscribe to contributors in one click.
"The Subscribe button for websites works just 'like' the button on Facebook; once clicked the user will begin seeing the public posts of the person they have subscribed to in his or her News Feed.
"The subscribe action is also shared - allowing others to subscribe directly via the News Feed stories, and further increasing viral distribution. Similar to the Like button, the Subscribe button can be easily added using XFBML or an iframe."
Various websites have partnered with Facebook for the service, including Absolute Radio, AllThingsD, ANSA.it, The Daily Beast, Forbes, GQ Italia, The Huffington Post, Mashable, Ministry of Sound, MSN, NME, TechCrunch, TIME and the Washington Post.
Forbes chief product officer Lewis D'Vorkin said in a statement: "Facebook is one more step in our ongoing effort to put authoritative journalism at the centre of social media. Forbes writers display their expertise not just on Forbes, but also in so many social streams.
"The Subscribe plugin allows our readers to stay connected to their favourite Forbes writers directly from their Facebook News Feed."
