Meta publishes the nine things the Threads feed measures before it decides what to show a reader. Buffer has measured 128,000 Threads posts to find which of those nine you can actually move. This article pairs those two with a study of 39,762,999 posts, a study of 2.5 million Threads posts, and three academic papers, and it names every tactic that has no evidence behind it.
The short version: Reply to the comments on your own posts, because that raised engagement 42% on Threads, the biggest lift of any platform measured. Reply to other people far more than you post, because the head of Instagram says all your replies together are worth about as much as all your posts. Post in the morning, because evenings lost on every day of the week. Post a video or a photo, because only 2.79% of the people who see a plain text post react to it, against 5.55% for a video. Keep links out of the post itself, because a link post is shown to fewer people. Post about more than one subject, because switching topics beat repeating the same subject in a study of 4.7 million posts. And just start, because 46.47% of early Threads accounts never posted once.

Learn the nine things Threads measures about a post, because every rule below comes from them
Meta publishes a document it calls a system card for the Threads feed. It lists the nine guesses Threads makes about you before it decides which post to put at the top of your screen. It is worth two minutes, because the rest of this article is just those nine turned into actions.
- Threads guesses how likely you are to like a post, to reply to it, to click it, to click the author's profile, and to keep reading after either click.
- Threads also guesses how long you will look at a post, and it counts that time as a good sign.
- Threads guesses how likely you are to scroll straight past a post, and that guess counts against the post. A post nobody stops on is punished, not ignored.
- "Likelihood to create a reply" is one of the nine, which is why every measured tactic on this page is about starting conversations rather than collecting likes.
- Meta gathers a portion of all public Threads posts plus everything from accounts you follow, then ranks that pile with the nine guesses.
- Meta has never published what the nine guesses are worth relative to each other, and it has never published what gets pushed down.

Reply to the comments on your own posts, because that raised engagement 42% on Threads
Buffer analysed nearly 2 million posts from more than 220,000 accounts across six platforms, of which 128,000 posts were on Threads. It compared each account against itself over time, so a big account's normal advantage cannot explain the result.
- Posts where the author replied to the comments got 42% more engagement on Threads than posts by the same author where they did not.
- Threads had the largest lift of the six platforms, ahead of LinkedIn at 30%, Instagram at 21%, Facebook at 9%, X at 8% and Bluesky at 5%.
- About two thirds of Threads accounts in the study did better on posts where they replied, so this is not a handful of big accounts skewing an average.
- Buffer says plainly it cannot prove replying causes the lift, because posts that do well attract more comments to reply to in the first place.
- Meta will not let you schedule a reply, and said in December 2024 that this was deliberate, to keep replying live.
| Platform | Extra engagement when the author replies to comments | Worth doing |
|---|---|---|
| Threads | 42% | Yes, the best of any platform measured |
| 30% | Yes | |
| 21% | Worth the time | |
| 9% | Small effect | |
| X | 8% | Small effect |
| Bluesky | 5% | Barely measurable |

Reply to other people far more than you post, because the head of Instagram says to
Adam Mosseri ran Threads until July 2025 and said this in an interview with Casey Newton of Platformer on 3 July 2024. It is the clearest growth instruction anyone at Meta has given about Threads.
- Mosseri said that if you are trying to grow, you should reply much more than you post.
- He said the sum of all your replies is worth about as much as the sum of all your posts.
- He gave the reason as well, saying replies help other people discover you through the conversations they create.
- Meta's Japan office said in July 2026 that replies account for more than half of everything people are shown on Threads worldwide.
- Nobody has measured whether replying to strangers grows your own account, so treat replying to strangers as Meta's advice and not as proof.

Reply even with no followers, because a Threads reply is judged on the post not the account
Researchers at the Polytechnic University of Marche built a map of every public reply in the European Union between 14 December 2023 and 21 February 2024. The map has 45,349 people in it and 72,333 reply connections between them.
- The most connected 2.59% of Threads accounts receive replies at nearly twelve times the rate of everybody else.
- Whether an account is already popular has almost no effect on who replies to it, because the study measured that link at effectively zero.
- That means a reply from a stranger on Threads is earned by the post, not by the follower count above it.
- The most connected accounts talk to each other about 56 times more densely than the network as a whole.
- Becoming one of those most connected accounts matters most, because their replies are what carry a post into other people's feeds.

Post in the morning between 6am and 11am, because evening posts did worse on every day
Buffer measured 2.5 million Threads posts and ranked every hour of every day by how much engagement the middle post got. Read all times as the reader's own local time.
- Weekday mornings from 6am to 11am were the best window on Threads.
- The single best slot was Thursday at 9am, followed by Wednesday at midday and Wednesday at 9am.
- The 6pm to 11pm window underperformed on every single day of the week, with no exceptions.
- Wednesday, Thursday and Tuesday were the best three days, and Saturday was the worst.
- Buffer's own earlier study said Wednesday at 7am, so even the same company gets a different answer ten months apart.
- Monday at 10am is when the most brands post to Threads, which makes it the busiest hour rather than the best one.

Do not spend long picking a posting time, because what you post matters far more than when
The company that published the best-time-to-post study also published the sentence that undercuts it. It is worth reading before you build a schedule around a single hour.
- Buffer's own conclusion from 52 million posts is that what you post matters most, how often you post matters a lot, and when you post matters least.
- Buffer says the best time is a window rather than a slot, and the difference between the top few windows is smaller than people expect.
- Buffer describes timing as something that helps a good post get its first push and cannot rescue an average one.
- Threads users are in the app for about five minutes a day, so a post has a short life whatever hour you send it.
Use Repeat Recorder to rehearse the line before you film a Threads video
The section below says video is the best performing format on Threads, and the reason most people avoid it is that the first take always sounds wrong. Repeat Recorder, one of my own apps, is built for that: it records what you say, then plays it back on a loop, so you can listen to the same fifteen seconds again and again and fix the one word that is off.
- Repeat Recorder loops your recording hands free, so you can rehearse with the phone face down on a table.
- 5.55% of the people who see a video post on Threads react to it against 2.79% for a plain text post, so the rehearsal is worth doing.
- Recordings stay on your phone and are never uploaded, shared or used to train anything.

Add a video or a photo, because plain text gets about half the reaction that video does
Threads is sold as a text app, and text is the format that performs worst on it. Buffer measured this across part of a set of more than 52 million posts collected through December 2025. Every percentage below is the share of the people who saw the post who then did something with it, meaning they liked it, replied to it, reposted it or quoted it.
- 5.55% of the people who see a video post on Threads react to it, against 4.55% for a photo post, 2.79% for a plain text post and 2.34% for a link post.
- Video beats plain text by 99% and a photo beats plain text by 63%.
- Buffer's own earlier study put photos ahead of video, so which of the two is best is genuinely unsettled and the gap between them is small.
- Both Buffer studies agree that plain text is well behind and that link posts finish last.
- Buffer warns that a good text post easily beats a mediocre video, so the format is a nudge and not a rule.
- Nobody has published figures for a Threads carousel, which is a post holding several pictures you swipe through, and the 21.77% figure people quote for one is Buffer's LinkedIn result.

Show one identifiable person in the photo, because crowd shots get almost no replies
Researchers took 62,321 Threads posts and 21,572 images through Meta's own research tool and modelled what actually predicted the likes each one got. The study covers a single protest movement in Taiwan, so read it as a strong hint rather than a universal law.
- What the post is about predicted its likes better than any other single feature the researchers measured.
- Photographs containing people took the largest share of views, likes and reposts, a repost being when a reader passes your post on to their own followers.
- A photograph of one identifiable person drew far more replies than a photograph of a crowd.
- A crowd photograph spread widely and started almost no conversation, which is the wrong trade on a platform that ranks replies.
- Formal wording raised likes and so did negative feeling, which is the opposite of the cheerful tone most brands write in.
- Drawings and computer generated pictures were passed on to other people's followers more often, without getting more likes.

Keep links out of the post itself, because link posts reach fewer people despite Meta's denial
First, clear up what this rule is not. Threads does not block links. You can put a web address in a post or in a reply, it becomes a normal clickable link, and anyone can tap it. The problem is that a post carrying a link is shown to fewer people, so fewer people ever reach the link.
- Links work normally on Threads, in the post itself and in replies, and Meta blocks nothing.
- Meta denies that it pushes link posts down, and Adam Mosseri said so directly in November 2024.
- Mosseri's stated reason for link posts doing badly is that people rarely like or comment on a link, and the feed ranks a post on how likely you are to do exactly those two things.
- Mosseri then said in June 2025 that Meta had been "working on making sure links are ranked properly", which is hard to square with nothing having been wrong.
- Buffer's data from six months after that fix still puts link posts last, with only 2.34% of the people who see one reacting to it.
- Write the post so it stands on its own without the link, and put the link in your first reply underneath it.
One hard limit does exist. The Threads posting tool rejects a post containing more than five links outright.

Post in most weeks of the year, because steady posting got 450% more reaction per post
Buffer followed more than 100,000 accounts across ten platforms including Threads for 26 weeks, and grouped them by how many of those weeks they posted in at all.
- Accounts that posted in 20 or more of the 26 weeks got 450% more engagement per post than accounts that posted in four weeks or fewer.
- Accounts that posted in 5 to 19 of the weeks got 340% more than the occasional group, so most of the gain arrives early.
- The gain per extra week shrinks fast, from 58% at week three down to 16% by week seven.
- Engagement peaked at week 21 and then flattened out, so this is not a reason to post forever without thinking.
- The average Threads account posts 6.46 times a week, measured across 1,059,949 accounts.
- Threads accounts with 100,000 to 1 million followers post more than 53 times a week, which is eight times the average.
Use Camera to Clipboard to add a photo to a Threads post you wrote on a computer
Posting six times a week gets slow if every picture has to be emailed from your phone to yourself first. Camera to Clipboard, another of my own apps, removes that step: you take the photo on your phone and it arrives on your computer's clipboard, ready to paste straight into the Threads box you are already typing in.
- Camera to Clipboard puts the photo on your computer's clipboard, so writing on a keyboard no longer costs you the picture.
- 4.55% of the people who see a photo post on Threads react to it against 2.79% for a plain text post, so the picture pays for the extra step.
- You can attach up to 20 photos or videos to one Threads post.

Post about more than one subject, because switching topics beat repeating the same one
Every growth guide tells you to pick one subject and never leave it. Two separate academic datasets point the other way on Threads, and this is the most surprising finding in the whole article.
- Researchers analysed 4,716,626 Threads posts and found that a post on a different subject to the author's last post did better than one on the same subject.
- Only 8.93% of Threads posts share a subject with the author's previous post, against 28.25% on Instagram, so subject switching is normal behaviour on Threads.
- A separate study found that people who post across more than one subject are 17.9 times more likely to be among the platform's most connected accounts.
- The topic switching finding and the multiple subject finding come from different research teams and different datasets, and they agree.
- The reason is that Threads ranks each post on its own merits and keeps no running score for your account, so a change of subject costs you nothing.

Tag exactly one topic per post, because Threads allows one and Meta says tagged posts get more views
Threads did not copy hashtags from Twitter. It built a different thing with a deliberate limit, and the limit has not moved since December 2023.
- Threads allows exactly one topic tag per post, and Meta said the reason is to make it easier for people who care about that topic to find the post.
- Meta said in 2025 that posts with a tagged topic generally receive more views than posts without one, and published no number alongside that claim.
- You can put up to ten topics in your profile bio, which is a separate limit from the one tag per post.
- Nobody outside Meta has ever measured whether a Threads topic tag helps, so this rests entirely on Meta's own word.
- Ignore any article claiming a specific percentage lift from Threads tags, because no study behind those numbers exists.

Ask a real question but never ask for likes, because Meta demotes posts that beg for likes
Meta calls asking for engagement "engagement bait" and publishes both the definition and the punishment. It also publishes a carve out that most people writing about this leave out.
- Meta defines engagement bait as a post that explicitly asks for votes, shares, comments, tags or likes for no reason other than to get them.
- The punishment is that Meta pushes the post down in the feed rather than removing it, and the demotion gets worse if you keep doing it.
- Meta says it has trained its systems specifically to avoid demoting posts that ask for help, advice or recommendations.
- So "what should I do about this" is protected and "comment YES if you agree" is not, even though both end in a question.
- Adam Mosseri said in October 2024 that engagement bait had increased on Threads and that Meta was working to get it under control.
- Nobody has measured whether question posts actually get more replies on Threads, so ask questions because they start conversations, not because a study says so.

Never trade follows with anyone, because Meta's spam rules ban exchanging engagement
Meta's Community Standards name Threads directly, so the Spam policy genuinely applies here rather than being borrowed from Instagram. The word that catches most people is "exchanging".
- Meta bans selling, buying or exchanging engagement such as likes, shares, views, follows and clicks.
- No money has to change hands, so a follow-for-follow arrangement and an engagement pod are both banned by the word "exchanging".
- Meta bans posting or engaging at very high frequencies, whether you do it by hand or with software.
- Meta bans making people like, share or follow you before they can see something, which it calls like-gating and share-gating.
- Meta's nearest official name for an engagement pod is a "coordinated comment network", and content from one is not eligible to be recommended.
- Buying Threads followers is the same rule, and 260 people a month search for how to do it anyway.

Try an idea as a ghost post, because it disappears after 24 hours and the replies go to your inbox
Ghost posts launched on 27 October 2025 and are the most searched Threads feature that nobody explains properly. About 720 people a month search for what one is.
- A ghost post is a normal Threads post that files itself away automatically 24 hours after you send it.
- Replies to a ghost post go into your direct message inbox instead of appearing publicly under the post.
- Only you can see who liked a ghost post and who replied to it.
- You turn a post into a ghost post by tapping the ghost icon while you are writing it.
- Meta's stated purpose is to let people post spontaneous thoughts without them sitting on the profile forever.
- A ghost post is the cheapest way to find out whether an idea gets a reaction before you commit to it as a normal post.

Retrain your own feed with "Dear Algo", because Meta shipped it as a real control in 2026
People kept posting messages addressed to the Threads ranking system as a joke. In February 2026 Meta shipped it as a working control, and it matters for growth because your own feed is where you find people to reply to.
- Writing a public post that starts with the words "Dear Algo" adjusts your own Threads feed for three days.
- You can pass somebody else's "Dear Algo" request on to your own followers to apply the same adjustment to your own feed.
- "Your Algo" arrived in June 2026 and does the same thing privately, for one, three or seven days, with nothing posted publicly.
- "Dear Algo" and "Your Algo" work only in the United States, Canada, Britain, Australia and New Zealand.
- Point your own feed at the subject you post about, because you cannot reply to conversations you never see.

Join a Community, because Meta credited them for taking Threads to 500 million users
Communities launched as a test on 2 October 2025 and became a finished feature on 16 June 2026, the same day Meta announced 500 million monthly users and said Communities were part of the reason.
- A Threads Community is a public group built around one subject, and Meta created the first hundred rather than letting users make them.
- Threads passed 200 Communities by December 2025 and added a Community Champion badge and small labels members can put next to their name.
- Community Champions are chosen for being highly followed inside the community and for actually talking in it.
- A Community Champion can host a Live Chat, which is a public group conversation with up to 150 active participants.
- Your community membership shows on your profile, so it doubles as a signal of what you post about.

Just start posting, because 46.47% of early Threads accounts never posted once
Researchers collected 1,253,438 Threads accounts in the month after launch and counted how many posts each one had written. The answer explains why the bar on Threads is lower than it looks.
- 582,459 of those 1,253,438 accounts, which is 46.47%, had never posted anything at all.
- A further 43.36% had written fewer than 25 posts, so nearly nine accounts in ten were barely active.
- An account with under 2,000 followers averages 761.31 views per post on Threads against 128.82 on X, so the reward for starting is real.
- Threads accounts average 1.65 posts a day, slightly more than Instagram accounts at 1.19.
- Reposts make up 20.83% of everything on Threads, so a fifth of the feed is people passing on somebody else's post.

Every Threads growth tactic ranked by the evidence behind it
Green means a measured study with a sample size, amber means Meta says so without publishing a number, and red means nobody has measured it at all.
| Tactic | What the evidence is | Size of the effect | How strong the evidence is |
|---|---|---|---|
| Reply to comments on your own posts | 128,000 Threads posts, each account compared to itself | 42% more engagement | Strongest on this page |
| Post in most weeks rather than occasionally | 100,000 accounts over 26 weeks | 450% more engagement per post | Large sample, Threads included |
| Post a video instead of plain text | Part of 52 million posts | 5.55% against 2.79% | Buffer's two studies disagree on the top format |
| Post a photo instead of plain text | Part of 52 million posts | 4.55% against 2.79% | Buffer's two studies disagree on the top format |
| Post about more than one subject | 4,716,626 posts, plus a second study | Better than staying on one subject | Two teams agree independently |
| Show one identifiable person in a photo | 62,321 posts, one movement, one language | Far more replies than a crowd photo | Narrow sample, strong method |
| Post on a weekday morning | 2.5 million Threads posts | Best window of the week | Buffer says timing matters least |
| Keep links out of the post itself | Part of 52 million posts | 2.34% react against 2.79% for text | Where to put the link instead is unmeasured |
| Reply to other people more than you post | Adam Mosseri said so in an interview | Replies worth about as much as posts | Meta's own advice, never measured |
| Tag one topic on the post | Meta's own newsroom statement | Generally more views, no number given | No independent measurement exists |
| Ask a question in the post | Nobody has measured it | Unknown | Do it to start a conversation, not for reach |
| Cross-post from Instagram to Threads | Nobody has measured it | Unknown | Meta has never said whether it helps |
| Write a post of a particular length | Nobody has measured it | Unknown | Every number in circulation is invented |
| Buy followers or trade follows | Meta's published Spam policy | Against the rules | Banned by the word "exchanging" |

Ignore these six popular Threads tips, because none of them has a study behind it
Every claim below is repeated across dozens of Threads growth articles. Each one was traced back to its source and the source does not exist.
- "Posts of 100 to 200 characters get 3.2 times the engagement" comes from one marketing page with no named author and no method.
- "Threads carousels get a 21.77% engagement rate" is Buffer's LinkedIn figure with the wrong platform name on it, and it is about six times too high for Threads.
- "Native Threads posts get 3 to 5 times the follower growth of cross-posted ones, per Meta's own data" is invented, because Meta has never published anything on cross-posting.
- "Links now perform 17% better than text-only posts, per Meta" contradicts the only real measurement, which puts links 19% below text.
- "Threads grades the speed of your first 100 reactions" appears on a dozen sites and traces back to nobody.
- Nobody has published a credible figure for how fast a typical Threads account gains followers, so treat "200 to 500 new followers a month" as fiction.

Conclusion: how to grow on Threads and get more followers, in one glance
Threads ranks each post on how likely a reader is to reply to it, so write to be replied to. These six are ordered by how large the measured effect is, and the table above holds the rest.
- Post in most weeks of the year, because that beat occasional posting by 450% per post.
- Reply to the comments on your own posts, because that raised engagement 42%, the biggest lift of any platform measured.
- Post a video or a photo rather than plain text, because 5.55% of viewers react to a video and only 2.79% react to plain text.
- Post about more than one subject, because two research teams found switching topics beats repeating the same one.
- Post on a weekday morning and keep the link out of the post, because evenings and links both lose.
- Start now, because 46.47% of early Threads accounts never posted anything at all.
