How the Facebook Algorithm Works in 2026 (What Meta Says)

The Facebook algorithm doesn't show you everything. It shows you what it predicts you'll care about. With more than 3 billion monthly active users and a huge volume of posts every minute, the system's job is to rank content by how much it will matter to you, not by how recent it is.

PostEverywhere schedules your Facebook posts at the times your audience is online, so you can put this guide into practice. See how it works.

The system has changed a lot in the past year. All videos are now Reels. Recommended posts from accounts you don't follow make up the biggest single share of Feed views in the US.

And Meta has started asking people directly whether Reels match their interests, to improve recommendations beyond likes and watch time.

This guide explains how Facebook's algorithm works across every surface in 2026 (Feed, Reels, Groups, Marketplace), the ranking factors that matter, the myths that don't, and the tactics that move organic reach. It also includes our own data on when Facebook posts did best.

TL;DR#

• Facebook ranks your Feed in four steps: gather inventory, leverage signals, make predictions, rank by score
• Recommended posts are the biggest source of Feed views. In Meta's latest US data, 36.6% of Feed views came from accounts people don't follow
• All videos are now Reels (rolled out from mid-2025), with no length or format limits
• Shares and conversation are strong signals; Meta says sharing a post is "often an indicator" of interest
• Only 1.1% of US Feed views were of posts with a link, so keep people on Facebook where you can
• Groups and Marketplace are their own surfaces with their own ranking
• Post on a steady rhythm. Use a dedicated Facebook scheduler to stay consistent

How Facebook's Algorithm Actually Works#

Every time you open Facebook, the algorithm runs a four-step ranking process to decide what you see and in what order. Meta has documented this process in its Transparency Center.

The Four-Step Process#

1. Gather inventory. The system gathers all the posts that could appear: posts shared by friends, Pages you follow and groups you've joined
2. Leverage signals. A lightweight model picks about 500 of the most relevant posts, using signals such as who posted, how you've interacted with them, and the type of post
3. Make predictions. Several machine learning models predict how valuable each post will be to you, for example how likely you are to scroll past it, open it full screen, or interact with friends or groups about it
4. Rank by score. Posts predicted to be most valuable are shown higher in your Feed

How Facebook ranks your Feed

Meta describes four steps. A light model first cuts everything that could appear down to about 500 posts, then more models predict how much each one will matter to you.

1. Gather inventoryPosts from friends, Pages you follow and groups you've joined.
2. Leverage signalsA light model picks about 500 of the most relevant posts.
3. Make predictionsSeveral models predict how valuable each post will be to you.
4. Rank by scorePosts predicted to be most valuable go higher in your Feed.

Two Types of Feed Content#

The Feed blends two kinds of posts:

• Connected content: posts from friends, Pages and people you follow, and Groups you've joined
• Recommended content: posts from accounts you don't follow, picked for your interests. In Meta's Widely Viewed Content Report for April to June 2026, these made up 36.6% of US Feed views, more than posts from friends (20.2%)

Where Facebook Feed views come from

Share of US Feed content views by where the post came from, April to June 2026. Only 1.1% of views were of posts with a link.

Where the post came from	Share of US Feed views
Recommended (not followed)	36.6%
Friends	20.2%
Pages and people you follow	14.8%
Groups you joined	14.6%
Other	13.8%

So Facebook is no longer just a "friends and family" app. It's increasingly a discovery engine, similar to how Instagram's Explore and Reels algorithms work.

The Ranking Factors That Matter#

Meta's Transparency Center publishes system cards that describe the predictions and signals the algorithm uses. It doesn't publish weights, and it says the models change often.

Signal Categories#

Explicit signals: actions you take, such as liking, commenting, sharing and reacting.

Implicit signals: how you behave without clicking, such as whether you scroll past a post or stop to look, and whether you open it full screen.

Relationship signals: how often you interact with a person, Page or group.

Content-type signals: whether the post is a photo, video, link or text, matched to what you tend to engage with.

Engagement prediction: how likely you are to engage with a post, or to click "Interested" or skip it.

Recency: newer posts can matter more, and Meta said in October 2025 it would show more Reels uploaded the same day.

High-Value Engagement Signals#

Meta doesn't publish a ranked list, and as it says in its explainer on how AI ranks content, "no single prediction is a perfect gauge of whether a post is valuable to you." These are the kinds of engagement that most clearly show interest:

1. Shares. Meta says sharing a post is "often an indicator" of interest (Facebook only shows share counts and public reshares to Page admins; see how to see who shared your post on Facebook)
2. Comments, especially conversations between people who know each other
3. Saves, which show someone wants to come back to a post
4. Reactions
5. Opening a post or profile, such as tapping into full screen or visiting the poster's profile
6. Time spent, including watching a video rather than scrolling past

What Gets Penalized#

• Engagement bait ("Like if you agree!", "Tag a friend who...")
• Repeat reposts of other people's content, which Meta has moved to limit
• Clickbait and misleading content: sensational headlines that don't deliver
• Spammy link patterns, especially to low-quality sites

How the Feed Algorithm Works#

The Facebook Feed is where connected and recommended posts meet. Its goal is to show you posts you'll find worthwhile, not just posts that get clicks.

What Drives Feed Ranking#

Interactions between people are at the core. Meta's predictions include how likely you are to interact with friends or groups about a post. A post that starts a real conversation gives Facebook much more to work with than one that collects a few passive likes.

Format preferences also play a part. The algorithm learns which types of posts you engage with. If you watch videos, you'll see more video; if you engage with photos, more photos. That's why results vary so much between accounts.

Posting time matters for the first responses. Publishing when your audience is online gives a post its best start. Our own data from posts scheduled with PostEverywhere, below, shows which days did best; see our best time to post on Facebook guide for the full picture.

A post's first responses help decide how widely Facebook shows it. PostEverywhere schedules your Facebook Page posts and Reels for the exact times you choose, and suggests times from your own results where the platform shares them. See the Facebook scheduler.

How the Reels Algorithm Works#

Since mid-2025, all videos posted to Facebook are shared as Reels, with no length or format restrictions, and the Video tab became the Reels tab. It's one of the biggest changes to the app in years.

How Facebook Reels Distribution Works#

Reels are Facebook's main way of showing your videos to people who don't follow you. The signals that matter most:

• Watch time. Whether people watch your Reel or scroll past it
• Shares. Sending a Reel to a friend is a strong sign of interest
• Same-day uploads. In October 2025, Meta said it would show 50% more Reels uploaded the same day people are scrolling
• Feedback. People can mark a Reel "Not Interested", and recommendations adjust
• Original content. Reposted or watermarked content is less likely to be recommended

Optimal Reels Specs#

• Length: as long as it needs to be. Facebook Reels have no length limit, so keep them tight enough that people watch to the end
• Format: vertical (9:16)
• Hook: the first seconds decide whether people stay
• Audio: your own sound or voiceover keeps the Reel clearly original

If you're already creating Instagram Reels, you can share the same vertical video to Facebook Reels. See our walkthrough on cross-posting Instagram Reels to Facebook Reels.

The UTIS Model (January 2026)#

Meta's engineers described a User True Interest Survey (UTIS) model for Reels recommendations in January 2026. Instead of relying only on engagement, Meta asks people in their feed how well a video matches their interests, and trains a model on the answers.

The results Meta reported:

• In offline tests, accuracy at spotting people's real interests rose from 59.5% to 71.5%
• In an online test with more than 10 million users, high survey ratings rose 5.4%, low ratings fell 6.84%, and total engagement rose 5.2%

This means Facebook is getting better at telling apart videos people scroll through and videos they genuinely value.

For scheduling Reels across Facebook and Instagram at once, use our social media scheduler. Instagram-first creators can start from Instagram Reels scheduling in PostEverywhere and add Facebook as a second destination.

How the Groups Algorithm Works#

Facebook Groups remain one of the best places for organic reach. In Meta's latest US data, posts from Groups people have joined made up 14.6% of Feed views, almost as much as posts from Pages and people they follow.

Why Groups Work Well for Reach#

Groups are built around shared interests, so members are more likely to comment and reply to each other. Meta's Feed predictions include whether you have strong intent to engage with a group's posts, so a lively group gives its posts a lot to work with.

How to Leverage Groups#

• Create or take part in niche Groups related to your brand
• Post content that invites discussion, not just announcements
• Reply to comments quickly to keep the conversation going
• Share your best Page posts to relevant Groups, where the rules allow
• Use Groups as a testing ground for ideas before publishing to your Page

How Facebook Marketplace Ranking Works#

Marketplace is a big part of Facebook: Meta says one in four of its young adult daily users in the US and Canada visit it every day.

Marketplace has its own ranking, described in Meta's Marketplace system card. It predicts the listings, sellers and content you're most likely to be interested in, using signals such as your activity, the product's category, condition and price, and how far away it is, then ranks them by score.

Meta's November 2025 update added collections, eBay and Poshmark listings, reactions and comments on listings, and tests of suggested questions in seller chats.

What Actually Works in 2026#

Here's what the data shows about what works on Facebook now, from Socialinsider's 2026 Facebook benchmarks, Meta's own reports, and our data from posts scheduled with PostEverywhere.

Content Format Performance#

Engagement rates from Socialinsider. Reels rose from 0.13% to 0.18% between 2024 and 2025, while links stayed at the bottom.

Key insight: In Meta's latest report, 98.9% of US Feed views were of posts with no link. Facebook favours content that keeps people on the app. Whichever format you choose, use the right social media image sizes so your posts aren't compressed or cropped.

Posting Frequency#

There's no official number. Socialinsider found the average brand posted about 39 times a month in 2025, 22% fewer than the year before, with the biggest drop in link posts. A sensible starting point:

• Feed posts: a few per week, up to one or two a day if you can keep quality up
• Reels: a couple per week
• Stories: often, to stay visible to your followers
• Group posts: a couple per week in relevant Groups

Posting more than you can keep good tends to lower how each post does. Plan your weekly rhythm with a Facebook content calendar template so you stay consistent without burning out.

Best Times to Post#

Our own early data from more than 500 Facebook Page posts scheduled with PostEverywhere:

• Best days: Sunday (28% better than the Page's usual post) and Saturday (19% better)
• Best time of day: the afternoon, from 3 to 6 PM
• Key principle: a post's first responses help it reach more people, so post when your audience is online

Use PostEverywhere's scheduling tool, or see our complete guide on the best time to post on Facebook for every day of the week.

Video Sharing Advantage#

Video is the format most likely to reach people beyond your existing audience, because all videos are now Reels and Reels are recommended to people who don't follow you. Shares carry them further.

9 Facebook Algorithm Myths Debunked#

Myth 1: "Only Reels and videos work on Facebook now"#

Reality: Reels are the best format for reaching new people, but they aren't the only thing that works. In Socialinsider's 2025 data, text status posts and albums had engagement rates as high as Reels. Use a mix of formats.

Myth 2: "Post more to get more reach"#

Reality: Each post is ranked on its own. More posts mean more chances, but posting more than you can keep good lowers how each post does. Quality over quantity: one post people share beats five they scroll past.

Myth 3: "Hashtags are essential on Facebook"#

Reality: Hashtags matter far less on Facebook than on Instagram or TikTok. Facebook's ranking runs on predictions about engagement and interest, not hashtag discovery. A few relevant tags are enough.

Myth 4: "Engagement bait boosts reach"#

Reality: Posts like "Like if you agree!" or "Tag a friend who..." are engagement bait under Meta's content distribution guidelines, and Meta demotes posts from accounts that repeatedly share it. Genuine questions and polls work. Forced engagement doesn't.

Myth 5: "You must pay for ads to get any organic reach"#

Reality: Organic reach still happens, mostly through Reels, Groups and posts that start conversations. Recommended posts are the biggest source of Feed views, which means people who don't follow you can still find you. Paid boosts help, but organic-only strategies still work.

Myth 6: "Longer videos perform best"#

Reality: Length alone doesn't help. Facebook Reels have no length limit, but watch time and whether people scroll past are what count. Make each video as long as it needs to be and no longer.

Myth 7: "There's a secret list of banned words"#

Reality: There's no published keyword blacklist that automatically suppresses posts. Ranking is based on predictions about each person's interest, and on Meta's community standards and distribution guidelines.

Myth 8: "Scheduling posts hurts your reach"#

Reality: None of the signals in Meta's ranking explainer look at how a post was published. Posts published through approved scheduling tools like PostEverywhere use Meta's official API and are ranked on the same signals as posts made by hand.

What can hurt reach is leaving Instagram's old auto-share-to-Facebook setting on, which posts badly cropped, hashtag-stuffed Instagram posts to your Page. Our guide to posting to Instagram and Facebook at the same time shows how to switch that setting off and use a real cross-posting workflow instead.

Myth 9: "Facebook is dead, only old people use it"#

Reality: Facebook has more than 3 billion monthly users, and Meta says one in four of its young adult daily users in the US and Canada visit Marketplace every day.

Younger people use Facebook differently (more Reels, Groups and Marketplace, fewer status updates), but the audience is huge and active.

Spend your time on posts worth sharing, not on posting them. PostEverywhere publishes to Facebook and every other top platform from one calendar. Start your 7-day free trial. Plans start at $9 a month.

Recent Algorithm Updates (2025-2026 Timeline)#

January 2026: UTIS Model Launch#

Meta's engineers described the User True Interest Survey model for Reels recommendations, which learns from people's answers to "how well does this video match your interests?" In offline tests it raised accuracy at spotting real interests from 59.5% to 71.5%.

December 2025: Facebook Redesign#

A redesign moved Marketplace into the main navigation bar, gave photos a grid and double-tap to like, and added ways to tell Facebook why you don't like a post. It signalled Facebook's direction: friends, photos and commerce.

October 2025: Reels Algorithm Overhaul#

Facebook updated its Reels algorithm to show 50% more Reels uploaded the same day, added "Not Interested" controls, AI search suggestions in Reels, and "friend bubbles" showing which posts friends have liked.

Mid-2025: All Videos Become Reels#

Meta announced in June 2025 that every video on Facebook would be shared as a Reel, with no length or format restrictions.

2025: Friends Tab Launch#

A revamped Friends tab launched in the US and Canada in March 2025, showing only friends' posts, Reels, Stories, birthdays and friend requests.

2025: Anti-Repost Policy#

In July 2025 Meta announced a crackdown on unoriginal content: accounts that repeatedly repost other creators' videos, photos or text without adding anything get reduced distribution and can lose monetization.

Reaction videos and commentary that add something new aren't affected. It matches Instagram's originality push.

2025: AI Content Treatment#

Meta labels AI-generated content and ranks posts on how people respond to them, whatever tools made them. Using AI tools to create content is fine; what matters is whether the result is genuinely interesting to people.

Overall Trend: Links and Referral Traffic#

You may have read that Facebook referral traffic to websites grew about 4x by March 2026. We couldn't find a primary source for that figure, so we no longer repeat it.

What Meta's own data shows is that links remain a small part of what people see: only 1.1% of US Feed views in Q2 2026 were of posts with a link, according to Meta's Widely Viewed Content Report.

If you want traffic from Facebook, earn it with posts people want to click, and don't rely on link posts for reach.

Facebook vs. Instagram: How the Algorithms Differ#

Both are owned by Meta, but they rank content differently.

The key difference: a polished Reel can do well on Instagram on visual appeal alone, but on Facebook it does best when it gets people sharing and talking. Facebook leans on conversation; Instagram on entertainment.

Both use Meta's ranking approach of predicting what each person will value, both discourage engagement bait, and both favour original content over reposts.

Facebook Algorithm Updates in 2026#

The picture from Meta's latest data:

• Recommendations lead. Posts from accounts people don't follow were the biggest source of US Feed views in Q2 2026 (36.6%), according to Meta. Your posts can reach people who've never heard of you.
• Links stay rare. Only 1.1% of US Feed views were of posts with a link in Q2 2026, down from 1.3% the quarter before.
• Reels lead discovery. All videos are Reels, and Reels are the main way Facebook recommends video to people who don't follow you.

How PostEverywhere helps with the Facebook algorithm#

Every algorithm in this guide rewards the same habits: posting consistently, posting when your audience is online, and making each post fit the platform. PostEverywhere is built for that:

• Schedule Page posts and Reels, written for Facebook rather than copied from another platform
• Post when your audience is around: best-time suggestions learn your Page's own times once it has about 30 posts with results
• Write and adapt captions with AI Studio, and keep a steady rhythm with the posting queue
• Let your AI agent do it: ask Claude or ChatGPT to draft and schedule a week of posts through PostEverywhere (connect your AI agent)

FAQs#

Does the Facebook algorithm penalize scheduling tools?#

No. Facebook provides an official API that approved scheduling tools use to publish posts. Posts scheduled through tools like PostEverywhere are ranked on the same signals as posts made by hand, because none of the ranking signals Meta lists look at how a post was published.

How often should I post on Facebook in 2026?#

There's no official number. A few Feed posts and a couple of Reels a week is a sensible starting point, and Socialinsider found the average brand posted about 39 times a month in 2025.

Post only as often as you can keep quality up. Use a content calendar to plan ahead.

Why is my Facebook organic reach so low?#

Most Page posts reach only a small share of followers, because every post competes with friends, Groups and recommendations. That's normal, not a penalty. To improve it: post Reels, create posts that get people commenting and sharing, post when your audience is active, and be active in Groups.

Track the right numbers with our Facebook metrics and KPIs guide.

Do hashtags work on Facebook?#

Only a little. Facebook's ranking doesn't rely on hashtag discovery the way Instagram or TikTok can. A few relevant hashtags are fine for context, but focus on posts people want to share.

Is Facebook Reels worth it for businesses?#

Yes. All videos on Facebook are now Reels, and Reels are the main way Facebook recommends video to people who don't follow you. Socialinsider found Reels engagement rose from 0.13% to 0.18% between 2024 and 2025.

If you're not posting Reels, you're missing Facebook's best organic discovery channel.

Are Facebook Groups still worth it in 2026?#

Yes. Posts from Groups made up 14.6% of US Feed views in Q2 2026, according to Meta, almost as much as posts from Pages and people followed. Group members talk to each other, which is exactly the kind of interaction Facebook's predictions look for.

Create or take part in niche Groups relevant to your brand.

How does Facebook treat AI-generated content?#

Meta labels AI-generated content, and its ranking is based on how people respond to each post, not on which tools made it. Using AI tools is fine. What matters is whether the content is genuinely relevant and interesting to people.

What's the best content format for Facebook in 2026?#

It depends on your goal. Reels reach the most new people. Text posts and albums had the highest engagement rates in Socialinsider's 2025 data. Links perform worst. The best strategy uses a mix: Reels for growth, posts that start conversations for engagement, albums for storytelling.
