The Threads app is Meta’s text-first social platform. You sign in with an Instagram account, post up to 500 characters with photos or video, and join public conversations. An AI-ranked For You feed and a chronological Following feed decide what you see, and replies drive reach more than likes.
Instagram Threads has changed considerably since launch, and most guides still describe the 2023 version. This one covers how Meta’s Threads actually works in 2026: the ranking signals, ghost posts, topic tags, communities, and the link myth that costs creators reach.

What Is the Threads App?
The Threads app is a text-based social network owned by Meta Platforms and built by the Instagram team. It launched on July 5, 2023, as a direct competitor to X, and reached 500 million monthly active users in June 2026 according to Meta’s own announcement.
Instagram is a photo and video platform where conversation happens underneath the content. Instagram Threads flips that arrangement, making the conversation the product itself. Meta’s stated aim was to take what Instagram does well and extend it into text, building a separate space for real-time updates and public discussion.
That separation runs deeper than branding. Meta’s Threads operates its own feed, ranking system, and norms, even while sharing an account graph with Instagram. Your followers there do not automatically become your followers here, and a post that performs well on one platform can sink on the other.
How Do You Sign Up for the Threads App?
You sign up by logging in with an Instagram account. Your username and any verification status carry over automatically, and you can then customise a separate Threads profile.
Three things happen behind the scenes at that moment. Anyone you blocked on Instagram is blocked on Threads from day one, so you never have to rebuild that list. Instagram’s Community Guidelines also govern your content and interactions here. Accounts belonging to under-16s default to a private profile, and in some countries that threshold rises to 18.
People in the EU get an additional option. They can browse Meta’s Threads without creating a profile at all, viewing content, searching for accounts, sharing links, and reporting posts. That mode does not allow posting, replying, or liking.
How Does Posting Work on the Threads App?
A standard Threads post holds up to 500 characters. Text attachments extend that to 10,000 characters, which turned the platform into a workable home for long-form writing rather than short updates alone.
The practical use of that pairing is simple. Write a tight hook in the visible post, then attach the depth for readers who want to go further. Anyone skimming the feed sees a short post, while anyone genuinely interested taps through to the full piece.
What media can you attach?
| Format | Limit or behavior |
| Photos | Multiple images per post, reorderable before publishing |
| Video | Up to 5 minutes per clip |
| GIFs | Built-in searchable library in the composer |
| Links | Supported with automatic preview cards |
| Polls | Up to 4 options, running for 24 hours |
| Music stickers | Available to all users |
What post types exist?
Four formats behave differently from a standard post:
- Ghost post — a text-only post that archives after 24 hours
- Quote post — wraps someone else’s post inside your own commentary
- Repost — shares a post to your followers unchanged
- Spoiler tag — hides a word, phrase, or sentence behind a tap
Does the Threads App Have Hashtags?
No. Meta’s Threads uses topic tags instead, and the platform allows one clickable tag per post rather than a block of hashtags at the bottom.
This trips up nearly everyone arriving from Instagram. Dumping fifteen hashtags into a Threads post does not work the way it does elsewhere, and Threads has been reported to hide hashtags on posts cross-posted from Instagram.
Adding a topic tag connects your post to a broader conversation and makes it eligible to appear when people browse that topic. Meta has said posts carrying a topic typically collect more views than posts without one. Tap Add a topic in the composer, pick one specific and relevant tag, and move on.
Treat it as a small lever rather than a growth hack. One well-chosen tag helps distribution. Fifteen recycled tags on every post now work against you.
Can You Edit or Schedule a Threads Post?
Yes to both, and both are free.
Editing is available for 15 minutes after publishing, and it costs nothing. That contrasts with X, where post editing sits behind a paid subscription tier. You cannot add or remove media once a post is live, so the edit window covers text corrections rather than reworking the post.
Native scheduling lets you queue posts in advance, scheduled up to 75 days out. Third-party schedulers work through the Threads API, which supports publishing, reply management, and performance data.
One caution on editing: making changes during the first hour, while your post is being tested for distribution, can disrupt its momentum. Fix typos quickly or leave them alone.
How Do Ghost Posts Work on Threads?
Ghost posts are text-only Threads posts that archive automatically 24 hours after publishing. Meta shipped the feature on October 27, 2025.
Toggle the ghost icon in the composer and your post appears in other people’s feeds wrapped in a dotted conversation bubble, marking it as temporary. Two mechanics separate it from everything else on the platform:
- Replies go to your DMs rather than appearing publicly under the post
- Only you can see who liked and who replied
Moving engagement into private view removes the pressure of a visible reply count, which is precisely why people use ghost posts for half-formed thoughts, questions they would rather not leave permanently attached to their profile, and anything they want off the record.
Two constraints matter before you rely on them. Ghost posts do not support photos or video, so they are text only. And because replies arrive as direct messages, Meta’s default DM settings shape who can actually respond to you.
What Are the For You and Following Feeds?
Threads gives you two feeds. For You is AI-ranked and mixes recommendations with people you follow, while Following is reverse-chronological and shows only the accounts you follow.
| Feature | For You | Following |
| Ordering | AI-ranked by predicted value | Reverse chronological |
| Source | Followed accounts plus recommendations | Only accounts you follow |
| Reach potential | Can expose you to non-followers | Limited to your existing audience |
| Best for | Discovery | Keeping up with specific people |
The Threads app is not chronological by default. Because the For You feed pulls in recommended posts from accounts a person has never encountered, a brand-new account with almost no followers can still land a post that travels widely. That single design decision is what makes Meta’s Threads worth posting on for anyone starting from zero.
How Does the Threads Algorithm Work?
The Threads algorithm is an AI ranking system that scores every eligible post against signals about your behavior, then orders your feed by the value it predicts each post will deliver. Meta documents this architecture in its Transparency Center.
How ranking actually happens
Every post starts in front of a small test audience. The system watches how that group responds, predicts how a wider audience would react based on those early signals, and then decides whether to push the post further.
This is why the first 30 to 60 minutes after publishing matter more than the following 23 hours. A post collecting fast, substantive engagement gets escalated. A post collecting slow engagement gets shelved, regardless of how good it is.
Why replies outrank likes
Most new users optimise for the wrong signal. A like registers passive approval and tells the ranking system very little. A reply shows that someone stopped scrolling and invested effort, which predicts far more reliably that a post deserves a wider audience.
The signals that move reach, in rough order of weight:
- Reply engagement — how many people respond, and how substantive those responses are
- Engagement velocity — how quickly that interaction arrives
- Follow probability — whether viewers act on a post by following you
- Profile clicks — curiosity strong enough to leave the feed
- Scroll-past rate — how many people skip without engaging
Adam Mosseri, head of Instagram, has told creators that the sum of their replies carries roughly the value of the sum of their posts. Replying to other people is a growth mechanic on Threads rather than a courtesy, and treating it as optional is the most common reason accounts stall.
Meta has also confirmed it actively down-ranks engagement bait. Posts openly farming replies and low-effort responses such as “nice post” or a lone emoji now cost reach instead of earning it.
Do links hurt your reach on Threads?
Not in the way most people believe, and the real answer is more useful than the myth.
In November 2024, Mosseri stated that Threads does not down-rank posts containing links, but explained that the system placed little value on click probability because people rarely like or comment on link posts. Those are two different things, and conflating them produced years of bad advice about hiding links in the replies.
Mosseri’s most recent public statement on this came in mid-2025, when he said link ranking had been fixed and link posts were performing considerably better. Meta has not updated that guidance since, and some creators report link reach softening again through 2026.
The practical takeaway is simple. Links were never actively suppressed; they were undervalued, and Meta has worked on closing that gap. Put the link in the post itself rather than hiding it in a reply, then give people a reason to engage with the post, because the engagement is what carries the link.
Can you control your own feed?
Meta has shipped two tools that let users steer recommendations directly:
- Dear Algo (February 2026) — post publicly telling the algorithm what you want more or less of
- Your Algo (June 2026) — set the same preference privately, lasting one, three or seven days
Availability matters here. Meta’s announcement confirms Your Algo rolled out in the US, Canada, the UK, Australia, and New Zealand. If you are outside those markets, the feature will not appear in your app yet.
Mosseri also announced in November 2024 that Threads rebalanced ranking toward accounts you follow, reducing recommended content from accounts you do not. Unconnected reach is harder to win now than it was in the platform’s first year.
How Do Replies, Reposts and Quotes Work?
Replies join a threaded conversation underneath the original post, appear publicly by default, and show up in the replies tab on your profile.
Reposting pushes a post to your followers unchanged and adds no commentary of your own. Quoting builds a new post around the original, giving you a distribution opportunity while still crediting the source. Strategically, the difference is worth understanding, because a repost hands someone else reach while a quote earns reach for both of you.
How Do Direct Messages Work on Threads?
Threads DMs launched in July 2025 after sustained user demand, and now cover most of what people expect:
- One-to-one messages
- Group chats holding up to 50 people who follow you, for users aged 18 and over
- Web and desktop messaging
- Message requests, which filter people you do not follow
- Inline translation inside conversations
Your default settings determine who can reach you, and those settings also govern who can reply to your ghost posts, since those replies arrive here rather than in the public timeline.
What Are Threads Communities?
Threads Communities are interest-based spaces organised around a shared topic instead of a follow graph. Meta launched them in beta in October 2025 and brought them out of beta in June 2026.
Each community carries its own custom icon and a custom emoji that replaces the standard like button, so posts inside a basketball community get liked with a basketball. Communities also support Live Chats, real-time conversations that now include co-hosting, alongside flair tags for organising discussion by subtopic and recognition badges for active contributors.
Meta credited communities with driving its recent daily-user growth. For a new account, they solve a problem the follow graph cannot: reaching a relevant audience before you have built any audience at all.
How Does Search and Trending Work?
Keyword search covers post content rather than usernames alone, and profile search supports username filtering to pull posts from a specific account.
Trending Now surfaces active topics on the search page and in the For You feed. Meta’s AI systems identify candidates using signals such as post volume and engagement, after which human content specialists review the list to remove anything misleading, duplicative or in breach of guidelines.
Can You Download Threads Videos?
Not through the Threads app itself. Meta has never shipped a download button, and the built-in Save option is a bookmark that points back to the original post rather than a file on your device.
That distinction catches people out constantly. A saved post disappears the moment the creator deletes it, or the account goes away. A downloaded file stays on your phone permanently and plays offline.
Saving a Threads video means copying the post link and running it through a browser-based tool. We built Clipzuno for exactly this: paste a public post URL and the original MP4 comes through at the resolution the creator uploaded, with no re-encoding on the way to your device. Photos arrive as JPEG, and carousels list each item separately.
Our full guide to downloading Threads videos covers the device-specific steps, including where iOS hides the file afterwards and which link formats work.
What Do Threads Insights Show?
Threads Insights is the platform’s built-in analytics panel, reached by tapping the chart icon on your profile.
It reports views, interactions, follower growth, and audience demographics, along with data on where your content was discovered. Link-click analytics arrived separately, letting you see whether link posts actually drive traffic.
Use it to identify which topics and formats generate replies rather than likes, since replies are what the ranking system rewards. Keep one thing in mind: Threads reach is noisy at small scale, so judge patterns across ten to fifteen posts instead of concluding a single result.
What Privacy Controls Does the Threads App Offer?
Meta’s Threads inherits Instagram’s control set and adds several of its own:
- Private profile — only approved followers see your posts
- Reply controls — decide who can respond to each post
- Reply approvals — review responses before they appear publicly
- Hidden Words — filter replies containing specific words or phrases
- Mention controls — limit who can tag you
- Time Management — built-in usage limits
If you decide the platform is not for you, Threads can now be deleted independently of Instagram. Our guide to deleting a Threads account walks through both menu paths and the 30-day reversal window.
How Does the Threads App Connect to the Fediverse?
Threads supports ActivityPub, the open protocol behind Mastodon and other decentralised platforms. Turning on fediverse sharing makes your posts visible to people on independent servers, who can follow and interact with you without holding a Threads account.
Meta restricts the feature to users aged 18 and over with public profiles.
The trade-off is permanence, and it deserves thought before you enable it. Content shared to the fediverse lives on servers Meta does not operate. If you later delete your Threads account, Meta asks those servers to remove your content but has no power to compel them.
Threads vs Instagram vs X
| Feature | Threads | X | |
| Primary format | Text | Photo and video | Text |
| Post length | 500 chars (10,000 attached) | 2,200-char captions | 280 chars free, longer paid |
| Video length | 5 minutes | 3-minute Reels | Varies by tier |
| Post editing | Free | Free | Paid subscription |
| Top ranking signal | Replies | Watch time, DM shares | Engagement |
| Login | Instagram account | Standalone | Standalone |
| Tags | One topic tag per post | Multiple hashtags | Multiple hashtags |
| Open protocol | ActivityPub | None | None |
On the X comparison, the honest picture is mixed. Similarweb data reported in January 2026 put Threads ahead of X in mobile daily active users, roughly 141.5 million against 125 million. X still reports a larger total user base at around 550 million, and its web traffic dwarfs Threads’ at approximately 145 million daily web visits versus single-digit millions. Threads leads on mobile habit, and X leads on overall scale.
Threads also has not yet turned into a meaningful business. Meta rolled out Threads ads across 200 countries during 2026, while the company’s finance chief said in April that Threads would not be a meaningful revenue driver this year.
How to Get Traction in Your First Week
Understanding the mechanics is one thing. Here is what the ranking system rewards, translated into actions:
- Reply far more than you post. Mosseri’s advice is to reply much more than you publish, so make replying the bulk of your time while you build history
- Publish when you can stay online for an hour. Early engagement decides distribution, so be present to answer
- Ask something answerable. A question people can respond to in one line outperforms a polished statement
- Add one topic tag, chosen for the post rather than recycled across every post
- Skip the engagement bait. “Comment below” and “tag a friend” now cost reach
- Give it 15 posts before judging. Reach is noisy at small scale, and new accounts start with a deliberately small test audience
Common mistakes worth avoiding: hiding links in replies based on outdated advice, editing a post during its first hour, and treating Threads like Instagram with fifteen hashtags.
Frequently Asked Questions
Do I need Instagram to use the Threads app?
Yes. Threads runs on Instagram authentication, and your username plus verification status transfer across at sign-up. People in the EU are the exception, since they can browse without a profile, though that mode does not permit posting, replying, or liking.
Is the Threads feed chronological?
Only if you choose it. The default For You feed is AI-ranked and includes recommended posts from accounts you do not follow. The Following feed gives you a purely reverse-chronological view of accounts you follow, with no recommendations mixed in.
Does the Threads app have hashtags?
No. Threads uses topic tags and allows one clickable tag per post rather than a block of hashtags. Meta has said posts carrying a topic typically earn more views than posts without one, so pick a single relevant tag instead of importing Instagram habits.
How long can a Threads video be?
Up to five minutes per clip. The Threads app provides no built-in way to download those videos, so saving one means copying the post link and running it through a browser-based downloader.
What is the difference between a ghost post and a normal post?
A ghost post is text-only, archives automatically after 24 hours, routes replies to your DMs instead of the public timeline, and hides likes and replies from everyone except you. A normal post stays on your profile permanently with engagement visible to all.
Why does my Threads post get no reach?
Reach depends on replies and how quickly they arrive rather than on likes. New accounts also begin with a small test audience because the system has no history to predict from. Building a consistent reply rate across your first weeks raises the default distribution for everything you publish afterwards.
Do links reduce your reach on Threads?
No. Mosseri confirmed in November 2024 that Threads does not down-rank link posts, though the system placed little value on clicks at the time. By mid-2025, he reported that link ranking had been fixed and link posts were performing considerably better. That remains his most recent public update, so test link posts on your own account rather than assuming.
Can people on Mastodon see my Threads posts?
Only with fediverse sharing enabled, which requires a public profile and an account holder aged 18 or over. Once active, people on ActivityPub servers can follow you, read your posts, and reply without ever creating a Threads account.
