How the Facebook Algorithm Works in 2021 and How to Work With It

Good morning to everybody aside from Brian, who simply requested the company-wide Slack channel “wow why do our natural Fb numbers so dangerous?” Nicely, Brian, the brief reply is the Fb algorithm. Learn on, and we’ll clarify.

First, let’s have a look at some benchmarks.

As of the top of 2020, natural attain continues to be on the decline. The common attain for an organic Facebook post is down to 5.2%. (For the report, on the finish of 2019 it was 5.5%, and the 12 months earlier than that it was 7.7%).

In the meantime, the average engagement rate in 2020 for an organic Facebook post was 0.25%. That quantity drops to 0.08% for these of you with greater than 100k followers.

These numbers ought to make everybody really feel a little bit bit higher (everybody aside from Brian, who ought to really feel sorry for being impolite). The algorithm could be fairly robust on branded natural Fb content material.

However each Facebook marketing strategy wants both organic and paid content, which implies it’s time to buckle up and determine what this complicated, mysterious galaxy mind needs us social media managers to do.

Happily, Fb simply dropped a bunch of recent data on the algorithm, so we’re going to fill you in on the most recent particulars.

What is the Facebook algorithm?

The Facebook algorithm decides which posts people see every time they check their Facebook feed, and in what order those posts show up. For its part, Facebook would like to remind us that there is no single algorithm, but rather “multiple layers of machine learning models and rankings,” built to predict which posts will be “most valuable and meaningful to an individual over the long term.”

In other words, instead of presenting every available Facebook post in chronological order, the Facebook algorithm evaluates every post, scores it, and then arranges it in descending order of interest for each individual user. This process happens every time a user—and there are 2.7 billion of them—refreshes their newsfeed.

While we don’t know all the details of how the Facebook algorithm decides what to show people (and what not to show people) we do know that—like all social media recommendation algorithms—one in every of its objectives is to maintain individuals scrolling, in order that they see extra advertisements.

What does this imply for manufacturers? Relating to incomes extra natural attain, the Fb algorithm will reward you for posting content material that individuals have interaction with.

A quick historical past of the Fb algorithm

The Fb algorithm isn’t static; engineers are always tinkering with it.

To make its predictions, the algorithm makes use of 1000’s of information factors, a.okay.a. rating indicators. Over time, rating indicators have been added, eliminated, and had their significance adjusted, relying on what Fb thinks customers wish to see.

Listed below are a few of the extra notable modifications.

facebook algorithm history


First issues first: everyone knows that Fb was born in 2004 when Mark Zuckerberg received dumped for being immodest (or at the least, that’s what I realized from lastly getting round to watching The Social Community).

Non-fictional accounts of Fb’s historical past, nevertheless, affirm that:

  • The Fb newsfeed debuted in 2006.
  • The Like button confirmed up in 2007.
  • In 2009, Fb premiered a sorting order the place the posts with essentially the most Likes received bumped to the highest of the feed.


Quick ahead a number of years to 2015, when Fb turned involved sufficient about person expertise to begin downranking Pages that posted a excessive quantity of overly promotional content material. (i.e., natural posts with content material equivalent to advertisements.)

Additionally in 2015, Fb gave customers the flexibility to nudge the algorithm immediately: the “See First” function let customers point out that they’d like a Web page’s posts to be prioritized of their feed.


In 2016, Fb added a “time spent” rating sign. In different phrases, it began measuring a submit’s worth primarily based on the period of time customers spent with it, even when they didn’t like or share it.

Stay video was additionally prioritized, because it was incomes 3x extra watch time than common video.


This was the 12 months that Fb began prioritizing emotional reactions, by weighing reactions (i.e., hearts or the offended face) greater than traditional Likes.

One other rating sign was additionally added for video: completion charge. In different phrases, movies that hold individuals watching to the top are proven to extra individuals.


In January 2018, Zuckerberg introduced that the Fb algorithm would now prioritize “posts that spark conversations and meaningful interactions.” (This was apparently in response to widespread criticism about Fb’s unfavourable results on, , the material of society as a complete.) The modifications had been meant to extend the standard of the time individuals spend on Fb, and take duty for a way the platform impacts its customers’ psychological well being and general well-being.

Manufacturers had legitimate issues about this shift. Posts from associates, household and Fb teams got new weight, over and above natural content material from organizations and companies. To get traction, manufacturers would now have to earn much more high-value engagement (eg., feedback, reactions, remark replies—and if a submit was shared over Messenger to a good friend, that counted too).


Updates in 2019 included prioritizing “high-quality, unique video” that retains viewers watching longer than 1 minute, and particularly video that holds consideration longer than 3 minutes.

Fb additionally began bumping up posts and content material from “shut associates”: i.e., those who individuals have interaction with essentially the most, whether or not that’s by tagging one another in images or DMing in Messenger.

In the meantime, Fb was receiving a number of criticism on two fronts. First, the algorithm’s function within the unfold of harmful misinformation. According to critics, the 2018 algorithm change elevated outrage and divisiveness, political polarization, and promoted misinformation and borderline content material. And secondly, critics didn’t just like the strategies or amount of private knowledge that Fb was amassing with a purpose to feed mentioned algorithm.


Fb introduced that it was serving to customers perceive the algorithm, and take control of their own data to provide the algorithm higher suggestions. Nonetheless, individuals have been more and more involved about their privateness, and for a lot of, “extra related advertisements” doesn’t look like a worthwhile trade-off.

In the meantime, on the faux information entrance, in 2020 Fb introduced that its algorithm will now consider the credibility and high quality of reports articles with a purpose to promote substantiated information reasonably than misinformation.

So the place does that go away us in the present day?

How the Fb algorithm works in 2021

In January 2021, Facebook released new details about its algorithm.

Supply: Facebook

You may learn the technical explanation over here, however right here’s the easy model.

How does the Fb algorithm work?

  1. First, Fb takes each submit accessible in a person’s community (a.okay.a. the “stock”), and it scores these posts in keeping with predetermined rating indicators, like sort of submit, recency, et cetera.
  2. Subsequent, it discards posts {that a} person is unlikely to interact with, primarily based on that person’s previous behaviour. It additionally demotes content material that customers don’t wish to see (i.e., clickbait, misinformation, or content material that they’ve indicated they don’t like).
  3. Then, it runs a “extra highly effective neural community” over the remaining posts to attain them in a personalised means. (For instance: Mona is 20% prone to watch tutorial movies from her chess Group, however 95% prone to submit a coronary heart response to a photograph of her sister’s new pet) and ranks them so as of worth.
  4. And eventually, it arranges a pleasant cross-section of media sorts and sources so {that a} person has an fascinating number of posts to scroll by.

So, what does this inform us about which components get a submit to the highest of the feed? The reply is that it will depend on whose feed we’re speaking about.

Fb says that it makes use of 1000’s of rating indicators. The whole lot from the velocity of a person’s web connection to whether or not they desire to interact by liking or commenting.

Nonetheless, over time Facebook has consistently talked about the identical 4 rating indicators as crucial in the case of how excessive up within the information feed a submit seems.

4 Fb algorithm rating indicators to think about:

  • Relationship: Is the submit from an individual, enterprise, information supply or public determine that the person typically engages with? (i.e., messages, tags, engages with, follows, and so forth.)
  • Content material sort: What sort of media is within the submit, and which kind of media does the person work together with most? (i.e., video, photograph, hyperlink, and so forth.)
  • Recognition: How are individuals who have already seen the submit reacting to it? (Particularly your folks). Are they sharing it, commenting on it, ignoring it, smashing that offended face?
  • Recency: How new is the submit? Newer posts are positioned increased.

After all, most of those indicators require that Fb monitor its customers’ behaviour. Which is the place the privateness vs. personalization debate comes up. (Once more.)

Lastly, in 2021, Fb continues to make an effort to be clear with customers about their data. As an example, the Access Your Information instrument is meant to assist individuals determine why they hold seeing advertisements for Moon Boots. (Maybe you set your location to … the moon?).

It stays to be seen how the privateness vs. personalization debate will play out. At Hootsuite, we’re optimistic: no good marketer needs to be creepy or annoying, anyway. And even when the overwhelming majority of Fb customers elect to return to pre-targeting days, each natural and paid content material on Fb will nonetheless should be compelling, informative, entertaining, and galvanizing.

So, within the meantime, let’s check out how manufacturers can work with the algorithm to optimize their natural attain.

11 suggestions for working with the Fb algorithm

Reply to your viewers

Whereas your branded content material won’t ever really have the ability to compete with anybody’s sister’s new pet, it’s nonetheless essential to prioritize constructing connections with every individual in your viewers.

Why? As a result of the algorithm prioritizes posts from Pages {that a} person has interacted with previously. Because of this bumping up your reply sport is vital, whether or not that’s in Messenger or the feedback.

If an individual has taken the time to speak to your model, don’t waste the chance: make them really feel heard, make them smile, or encourage them to screencap it and ship it to their groupchat with the single-tear smile emoji.

Professional tip: Whether or not you’re a solopreneur or you could have a complete staff of neighborhood managers in place, Hootsuite Inbox makes managing these conversations at scale lots simpler.

Get your viewers replying to one another

This tip comes from Facebook itself. Apparently, if a submit has triggered a number of dialog amongst a person’s associates, the algorithm applies “action-bumping logic” to indicate that submit to the person once more.

That signifies that essentially the most fascinating conversation-starters get extra attain, within the type of second probabilities.

The algorithm values content material that individuals wish to share and focus on with their associates. (Notice that this doesn’t imply that the algorithm needs you to encourage strangers to get into flame wars.)

Purpose for love greater than likes

For the previous couple of years the algorithm has weighed response buttons extra closely than a easy Like. So goal emotional reactions in your posts: love, caring, laughter, disappointment, anger.

In case you’re undecided what’s going to resonate together with your viewers, a social media sentiment analysis is a good place to begin.

Publish when your viewers is on-line

You’ve heard this one a thousand instances, however we have now to emphasize it once more, as a result of Fb retains stressing it.

Recency is a key sign. The most recent posts go to the highest of the information feed.

After all, all shouldn’t be misplaced if a person misses a submit (as an example, in the event that they load their newsfeed, however then their boss walks by in order that they shut it) there’s nonetheless an opportunity that they’ll see that submit after they log in subsequent: the algorithm’s “unread bumping logic” signifies that unseen posts will likely be “added to eligible stock for this session.”

That mentioned, the simplest win on this checklist is to schedule your posts to go up at the best time for your Facebook audience.

Skip the algorithm utilizing Fb Tales

The factor about Facebook Stories is that they aren’t a part of the newsfeed. They float above it (actually and figuratively) they usually aren’t ruled by the algorithm. In accordance with Fb, they’re additionally efficient at driving site visitors: 58% of individuals say they’ve visited a model’s web site for extra data after watching a Story.

What sort of Fb Tales must you submit? In accordance with a study by Facebook, individuals say they need the next from branded Tales:

  • 52% need Tales which can be straightforward to grasp
  • 50% wish to see new merchandise
  • 46% need suggestions or recommendation

Are likely to your branded Fb Group

The benefit of operating a business Facebook Group is that, whereas it does take some care and feeding, it opens one other channel so that you can join together with your prospects, followers, and neighborhood.

It’s additionally a second channel for vital content material to succeed in your viewers’s eyes. The Fb algorithm prioritizes posts from Teams customers care about, so a submit that will get amplified in a preferred Group by fans and followers is likelier to earn extra attain.

Go Stay on Fb

In 2020 everybody was caught at residence and Live video on Facebook within the U.S. jumped by 50%.

As a result of Stay video receives 6x more engagement than common video, the algorithm actually, actually likes it. For manufacturers, it takes a little bit of know-how, however given the truth that virtual events don’t appear to be going away anytime quickly, Stay video successfully feeds two birds with one scone.

Grow to be a favorite

Do you know that each Fb person has thirty slots for his or her favorite Pages and other people? These thirty fortunate geese get an computerized free cross from the algorithm.

That is a part of Fb’s push to let individuals have extra management over what they see. Let your followers know that they can prioritize your content in their own timelines, in the event that they wish to.

list of favourite pages and people

Professional Tip: That is what is named a “large freaking ask,” so strategy it with sensitivity. There needs to be a stable motive for individuals to prioritize your content material, whether or not that’s as a result of it’s actually entertaining, or as a result of it’s really vital they keep knowledgeable.

Make longform video that individuals wish to watch

Watch time and completion charge are each essential rating indicators for video as a result of they point out that the viewer loved the video sufficient to observe the entire thing.

Briefly, the longer you retain individuals , the upper your video submit will likely be scored by the algorithm, and the upper up within the Fb newsfeed it should seem.

As of 2019, Fb additionally scores and prioritizes the next indicators for video:

  • Loyalty and intent: movies that individuals seek for and return to;
  • Video size and examine period: movies that individuals watch previous the 1-minute mark, and which can be longer than 3 minutes;
  • Originality: movies that aren’t repurposed from different sources and which have loads of added worth.

Which brings us to our subsequent level:

Don’t submit clickbait or misinformation or different evil issues

Don’t do it!! Don’t do any of these items, or the algorithm will spite you, and in addition we at Hootsuite will likely be actually disillusioned in you.

  • Hyperlinks to websites that use scraped or stolen content material with no added worth
  • Borderline content material (a.okay.a content material that isn’t fairly prohibited however most likely needs to be)
  • Misinformation and fake news
  • Misleading health information and harmful “cures”
  • “Deepfake videos” or manipulated movies flagged as false by third-party fact-checkers

Develop your attain by way of your finest advocates

Your workers have extra credibility and authority with the Fb algorithm than your model web page does. It’s because they’ve extra credibility and authority with their very own followers and associates.

Plus, they know the within scoop in your model, so what they are saying could be a lot extra significant than something your copywriter comes up with. (Sorry, fellow copywriters.)
