Nobody outside Meta knows the ranking function. Facebook is, however, the best-documented feed in the industry at the level of process. Meta’s Transparency Center describes the pipeline, names the signal categories, and publishes a list of what it demotes. That is more than most platforms offer, and it is still not a formula.
The short answer: Facebook Feed ranking is a prediction problem. Meta predicts what you will do with each candidate post, scores it, and sorts.
What Meta says it optimises for
Meta describes four stages: inventory (all eligible new posts or posts with new activity, minus policy-violating content), signals (thousands of them, from your actions and inferred behaviour), predictions (how likely you are to comment, share, hide, or report), and ranking by score. Meta states it combines over 100 different prediction models to produce the final order, and that it balances for content diversity on top of the score.
The prediction targets are the important detail. Meta does not only predict positive actions. It predicts angry reactions, reports, and hides, and demotes accordingly.
Note: Figures here were verified against Meta’s Transparency Center pages on ranking and content, approach to ranking, and types of content we demote, as of September 2026. Platforms change these without notice.
What signals does Facebook rank on?
Meta groups signals into four categories. Ordered as Meta presents them.
| Signal category | What Meta includes |
|---|---|
| Who you are and what you do | Account information, activity patterns, device, interaction history with the poster |
| The post itself | Privacy setting, media type, content analysis, predicted policy violations |
| Who posted it | Account history, posting volume, engagement metrics |
| Aggregate social interaction | Views, likes, comments and shares the post has received |
And the demotion list, which Meta publishes explicitly:
| Demoted category | Meta’s description |
|---|---|
| Clickbait links | Headlines or descriptions designed to deceive people into clicking |
| Engagement bait | Posts that artificially solicit likes, comments, shares or tags |
| Fact-checked misinformation | Content rated false by third-party fact-checkers |
| Likely policy violations | Content predicted to violate Community Standards |
| Borderline content | Sexually suggestive, near-hate-speech, graphic imagery, demoted per-person |
What changed most recently
Stated by Meta: the four-stage description and the demotion categories are the live published position on the Transparency Center.
Widely reported, not confirmed: the shift toward recommended (unconnected) content in Feed. Meta has discussed increasing recommendations from accounts you do not follow in earnings commentary and product announcements, but there is no published share-of-feed figure to quote, so we are not quoting one.
Practitioner heuristic: the idea that Facebook Pages get “5 percent organic reach.” No such figure comes from Meta. Organic Page reach varies enormously by page, audience and format, and every widely-cited number traces back to third-party samples, not to Facebook.
Myths this kills
Shadowbans. Facebook is the clearest case anywhere that the underlying worry is real and the word is wrong. Meta publishes exactly what it demotes and why. If your reach dropped and you posted a “tag three friends” caption, that is engagement bait, which is on the published list, and no secret ban is required to explain it. Read what a shadowban actually is before assuming anything hidden.
Engagement pods. Unfounded, and specifically counterproductive on Facebook. Meta predicts negative actions too. Coordinated inauthentic engagement is a policy problem, not a growth tactic.
“The algorithm hates links.” Meta demotes clickbait links. It does not publish a penalty for links as such. A link post that accurately describes its destination is not in a demoted category.
Posting time is decisive. No. Facebook Feed is not chronological, and posts with new activity re-enter inventory. Timing sets the initial conditions and little else. Our best time to post on Facebook guide and the Facebook posting time tool give you windows to test against, and how often to post on Facebook covers cadence, which matters more.
What actually moves distribution, in priority order
- Not being in a demoted category. This is free and most accounts get it wrong at least occasionally. Check your captions against the engagement-bait definition.
- Predicted meaningful interaction. Comments and shares from people with real prior connections to you.
- Format fit. Video, and particularly Reels, is a different inventory pool from a link post. Choose deliberately.
- Whether people hide, report, or react angrily. Negative predictions are ranking inputs, and they are the fastest way to lose reach.
- Poster history. Meta names account history and posting volume as signals.
- Consistency. Not a signal. It is how you accumulate the history that is one.
What to do
Read Meta’s demotion list once, properly, and audit your last twenty posts against it. Then write posts that a person would comment on because they have something to say, not because you asked them to. Pick one format per goal rather than posting everything everywhere in the same shape.
Scheduling Facebook alongside everything else
Facebook Pages, Instagram, and 13 other platforms sit in one calendar in BulkPublish, and per-platform text means a Facebook post is not forced to be a copy of the Instagram caption. That distinction matters here, because the demotion categories are about wording. The scheduling feature page has the detail.
The parts you control
Format, hook, consistency, and one Facebook-specific extra: whether you are quietly sitting in a published demotion category. You cannot see the score. You can read the rules, and most people never do.
