How the Threads Algorithm Works
Threads has two feeds that work in opposite ways, and one small posting rule, a single topic tag, that most people carry over wrong from other apps.
The Threads algorithm is the AI ranking system Meta uses to order the For You feed. It mixes posts from accounts you follow with recommended posts from accounts you don't, and orders them by predictions of what you'll interact with. Threads also has a Following feed that shows only accounts you follow, newest first, with no ranking at all.
So yes, Threads has an algorithm, but only one of its two feeds uses it. For posters, the lever that works differently from other apps is the topic tag: Threads allows one topic per post, not a string of hashtags, and that single tag is how a post signals which conversation it belongs to. In a March 2025 announcement, Meta said posts with a topic tag generally get more views than posts without one.
Meta publishes an explanation of the Threads feed on its Transparency Center, in its series on how AI systems rank content. It describes three stages. First, the system gathers an inventory: public Threads posts plus posts from accounts you follow. Second, it evaluates signals about you and about each post. Third, it ranks the candidates, putting first the posts it predicts you'll find most valuable.
The predictions it lists are about specific actions: how likely you are to like a post, reply to it, click into it, click the author's profile, spend time on the post, or scroll past it. The signals behind them include what you've recently liked and replied to, how long you've looked at similar posts, and how you've interacted with the author, measured over windows that Meta describes as ranging from an hour to many weeks.
The second feed is the other half of the design. Following shows posts only from accounts you follow, in time order. Meta lists it among the controls you have, alongside unfollowing, muting and hiding posts. That split matters for anyone posting: your followers can see your posts in time order if they choose Following, but most distribution to strangers happens in For You, where the ranking decides. For a new account with few followers, For You is almost the only place new readers come from.
Does Threads have an algorithm?
Yes, for the For You feed. Meta calls it an AI system rather than an algorithm, and it's the same kind of machine-learned ranking that orders Instagram's feed, built for text-first posts. The Following feed has no ranking: it's reverse-chronological.
The practical effect is that the same post can travel very differently depending on who's looking. In Following, it appears to your followers when they scroll to that moment. In For You, it can reach people who've never heard of you, if the ranking predicts they'll reply, like or linger. The public counts under a post, likes, replies and reposts, are what those strangers see at a glance, which is why accounts pay attention to them, and why some use Threads likes on a post they want to look alive when it lands in For You. That changes the visible count; the ranking itself runs on predictions about each viewer.
How does the Threads algorithm work?
In the terms Meta publishes, it predicts how each viewer will interact with each candidate post and ranks by those predictions. The actions it models include:
- Liking the post.
- Replying to it.
- Clicking into the post, and then liking or continuing to engage.
- Clicking the author's profile.
- Spending time on the post or on its page.
- Scrolling past it, which counts against it.
Why replies matter so much on Threads
Threads is built around conversation, and several of the modeled actions are about going deeper into a post: replying, opening it, reading the replies, visiting the author. A post that starts a real exchange produces all of those at once. That's why posts that ask something specific, or take a clear position people want to answer, tend to outperform posts that only announce something. It's the same reason how the X algorithm ranks posts weights replies heavily there too, though the two systems are built differently.
How does Instagram Threads algorithm work with Instagram?
Threads is Meta's app and was launched connected to Instagram accounts, and Meta describes the Threads feed in the same framework it uses for Instagram's feeds. What it doesn't publish is a precise list of which Instagram signals feed Threads ranking, so be wary of guides that claim to know. What's documented is that the ranking uses your activity on Threads, and that you can steer it with the controls Threads gives you.
What does a topic tag do on Threads?
It files the post under a topic. Instagram's help center, which covers Threads, says you can add one topic per post. The tag appears as a link on the post, without a hash sign, and it can contain spaces. Tapping it opens the topic's search view, where people browse posts about that subject.
This is the part people get wrong when they arrive from other apps. On Instagram or TikTok, a caption can carry a pile of hashtags. On Threads, only one topic tag is attached to a post, so choosing it is a decision about which conversation to enter, not a keyword list. A narrow, accurate topic puts the post in front of people browsing that subject; a broad one puts it in a crowded stream. The same logic is behind the question of whether hashtags still help on other networks, which do hashtags still work on X answers for X.
How to reset Threads algorithm
Threads doesn't document a single reset button for the whole feed in the way it documents its other controls, and the settings menus have moved between app versions. What you can do reliably is change the signals:
- Tap the menu on posts you don't want and choose Not interested, or hide them. Repeating this teaches the ranking faster than anything else.
- Mute or unfollow accounts whose posts crowd your feed.
- Switch to the Following feed when you want only accounts you follow, in time order.
- Look in Settings for content preferences, where some versions of the app offer options to refresh suggested content.
- Interact deliberately with the posts you do want: replies and time spent are the signals the ranking weighs.
How to change algorithm on Threads with Dear Algo
In February 2026 Threads launched a feature called Dear Algo. You write a public post starting with Dear Algo and say what you want to see more or less of, and your feed is adjusted for three days. Because the request is a public post, others can see it and repost it to apply it to their own feeds. At launch Threads said it was available in the U.S., the U.K., Australia and New Zealand, with more countries planned.
How does the Threads algorithm treat a new account?
With few followers, Following does little for you, because few people have you in it. Distribution to strangers comes from For You, where each post is judged by predicted interaction from each viewer. That's good news in one way: the ranking isn't a follower count, so a new account's post can travel if it gets the kinds of responses the model rewards.
The practical moves follow from that. Reply to other people's posts in your subject; a good reply is seen by everyone reading the thread and brings profile clicks. Pick one accurate topic tag per post. Post things people can answer. And don't read too much into one quiet post: the ranking predicts per viewer, and a single post can simply miss.
When reach drops across everything at once, check your account status before blaming the ranking. Meta's apps can limit recommendations for accounts that break recommendation guidelines, which is what most people mean by a shadowban, a term what shadowban means untangles platform by platform.
What the visible numbers do on Threads
The ranking works on predictions nobody else sees. What a stranger sees is simpler: the like, reply and repost counts under the post, and the follower count on the profile. Those public figures are what people read in the second before deciding to stop, and they're what Threads likes, Threads followers and Threads reposts change. None of them makes the ranking predict anything different for a given viewer, and none replaces a post that invites a reply. For every Threads service in one place, see the Threads hub.
Questions people ask about the Threads algorithm
Does Threads have an algorithm?
Yes. The For You feed is ranked by an AI system Meta describes on its Transparency Center. The Following feed isn't ranked; it shows accounts you follow in time order.
How does the Threads algorithm work?
It gathers public posts and posts from accounts you follow, then ranks them by predictions of whether you'll like, reply, click, visit the author or spend time on each post.
How many topic tags can you add on Threads?
One per post. The tag appears as a link without a hash sign, can include spaces, and opens a view of posts on that topic.
How do I reset my Threads algorithm?
Mark posts Not interested, mute or unfollow accounts, use the Following feed, check Settings for content preferences, and interact with the posts you want. Where available, Dear Algo adjusts the feed for three days.
What is Dear Algo on Threads?
A feature launched in February 2026: a public post starting with Dear Algo that asks for more or less of a subject adjusts your feed for three days. It launched in the U.S., U.K., Australia and New Zealand.
Does follower count matter for the Threads algorithm?
Less than on some apps. For You ranks each post by predicted interaction for each viewer, so a new account's post can travel. Followers matter most in the Following feed.
