Bluesky vs Threads for Business: The 2026 Data

If you're weighing Bluesky vs Threads for business, the raw size comparison isn't a contest. Threads passed 500 million monthly active users in June 2026. Bluesky is somewhere north of 43 million registered accounts, with daily actives in the low millions. Threads is more than ten times the size and it has Instagram's entire install base feeding it.

Then you look at what the traffic does after it arrives. When the Boston Globe compared referral sources, Bluesky sent 3x the traffic of Threads and drove 4.5x more conversions to paying digital subscribers. Same publisher, same content, wildly different outcomes.

That gap is the whole decision. If you have time for one text platform, "which is bigger" is the wrong question, because you're not going to reach 500 million people either way. The right question is which platform's users do the thing you need them to do.

This post compares both on the things that change your results: audience size, engagement, link traffic, and how reach actually gets allocated. Then a verdict on which business should pick which. Where a number is old or contested, we say so.

The size gap is real, and it's not close

Start with what isn't in dispute.

A few things worth flagging in that table before we go further.

Bluesky's registered-account number is not an audience. Registered accounts include everyone who signed up during a news-cycle spike and never came back. The daily-active figure is the honest one, and even that varies by source depending on how it's measured — you'll see 1.5 million and you'll see 4 million, both published in 2026. Treat any precise Bluesky DAU number with suspicion, including ours.

Threads' number has the opposite problem. It's a real 500 million, but a chunk of it arrived through Instagram prompts rather than intent, and Meta counts a monthly active generously.

Why every "engagement rate" comparison you'll read is guesswork

Search "Bluesky vs Threads engagement rate" and you'll get confident percentages for both. Most of them are made up, and here's the specific reason why.

Bluesky's API does not expose impressions. There is no reach number, no view count, no native analytics at all. Engagement rate is interactions divided by impressions, and one of those two numbers does not exist on Bluesky. So nobody can calculate it. Anyone quoting you "Bluesky's engagement rate is X%" either got it from a tool that estimated the denominator or invented it.

Buffer handles this correctly in its 2026 State of Social Media Engagement report, which analysed nearly 2 million posts across 220,000+ accounts. For Threads it reports a median engagement rate of about 3.6% in 2025, down from roughly 4.4% the year before. For Bluesky it reports raw interactions instead — a median of about 4 per post, down from about 5 — precisely because the rate can't be computed.

We went looking for a cleaner number and found a widely-cited post claiming Threads sits at 6.25%. That figure appears nowhere in Buffer's report. The closest match is LinkedIn at 6.2%. Somebody copied a row from the wrong platform, and it's been repeated since.

So the honest summary is: Threads has a measurable and slowly declining engagement rate. Bluesky's is unmeasurable by definition, which means the case for Bluesky can't rest on engagement percentages. It has to rest on what happens after the engagement — which is where the picture changes sharply.

Links: the difference that shows up in your analytics

For most businesses, social isn't the destination. The post is a means of getting someone onto your site, into your trial, or onto your list. So the metric that matters is not likes. It's clicks that leave the platform.

This is the widest gap between the two, and it isn't subtle.

Chartbeat's data, reported by Engadget in July 2025, found Threads accounted for less than one tenth of one percent of publisher referral traffic, sustained across an eighteen-month window. For scale, Facebook sits at 2–3% and Google Discover at 13–14%. Threads was sending about 28.4 million outbound referrals a month at that point — a big-sounding number that is close to nothing spread across the whole web and 115 million daily users.

Bluesky, with a fraction of the users, punched far above it. A Similarweb analysis found Bluesky drove 5x more referrals to nytimes.com than Threads did (1.5 million visits versus 300,000), 6.8x more to bostonglobe.com, and 2.6x more to theguardian.com.

The honest caveat: that Similarweb analysis covers November 2024, and the Boston Globe numbers are from the same period. They're the most detailed public side-by-side that exists, and no one has published an equivalent since, but they're old enough that you should treat them as directional rather than current. Adam Mosseri has said Threads fixed how it ranks link posts and that links have performed better since. That's a genuine improvement, and it also hasn't yet moved Threads' publisher referral share off the floor.

The structural reason behind the gap hasn't changed, which is why the direction probably holds. Bluesky's COO has said plainly that the platform welcomes publishers and doesn't demote links. Meta's business model is built on keeping attention inside Meta. One of those is a policy choice that could flip tomorrow; the other is the reason the company exists.

Reach: one of these you can buy

Until recently, both platforms were purely organic. That changed. Meta completed its global rollout of Threads ads in early 2026, covering image, video, carousel, Advantage+ catalog, and app formats. Threads is now a default-on placement in Meta Ads Manager — if you run Meta campaigns, you have to actively deselect it to stay off.

That cuts both ways for a business.

If you have budget and an existing Meta ads operation, Threads just became the easier platform. You can buy reach today, target with Meta's data, and measure it in a dashboard your team already knows. Inventory is new, so CPMs are still soft.

If you don't have budget, Threads just got harder. Organic reach on any ad-supported feed competes with paid inventory, and that competition only goes one direction over time. We've watched this movie on Facebook and Instagram.

Bluesky has no ads at all — no promoted posts, no boost button, no targeting. Everything is earned. That's a real constraint, and it's also the reason a one-person business can outperform a brand with a media budget there: nobody can buy the position ahead of you. Reach goes to whoever is most useful in the conversation, and distribution runs through custom feeds people opt into rather than a single algorithm you have to appease.

The verdict: Bluesky vs Threads for your business

The pattern: Threads is the better awareness channel, Bluesky is the better acquisition channel. If your goal is impressions in front of a broad consumer audience, size wins and Threads has it. If your goal is qualified people arriving on your site, the referral data says Bluesky punches far above its weight.

And if you can only do one properly, do one properly. A neglected presence on both beats nothing, but it loses to a good presence on one. These platforms don't reward cross-posted duplicates — Bluesky in particular treats recycled ad copy as exactly what it is.

Where X fits

Worth being straight about this since it's the third option most people are weighing. X is still substantially bigger than both and still sends more raw referral traffic than either. The Similarweb analysis found X drove only about 1.7x the traffic to nytimes.com that Bluesky did, despite having roughly 33 times more total web traffic — so its efficiency per user is poor, but the absolute number is still larger.

If you have an established X audience that converts, don't torch it to make a point. Keep it and add whichever of the two above fits your model. The migration decision and the "which new platform" decision are separate, and treating them as one is how businesses end up with three half-dead accounts.

If you pick Bluesky, here's what actually works

The Bluesky advantage in that referral data isn't magic. It comes from a culture where replies drive more profile visits than broadcasts, and where being useful in someone else's thread is the primary growth mechanism. That has practical consequences for how you run the account:

• Search is your targeting. You can't buy an audience, but you can find every person who typed your problem out loud this week. That's what replaces ad targeting.
• Reply more than you post. Roughly four helpful replies for every promotional one. This is the 80/20 rule everyone repeats, and it's repeated because it works.
• Speed matters. "Can anyone recommend a…" posts have a shelf life of hours. First helpful reply wins; a reply a week later is talking to an empty room.
• Use your domain as your handle. Free, and it's the platform's real trust signal. Our custom domain guide covers the setup.
• Ship links without fear. The one platform that doesn't punish you for it.

The hard part is the third bullet. Running fifteen keyword searches every morning before the threads go cold is a job nobody sustains for more than a fortnight. That's the piece SkyGrow automates: you set your keywords once, it scans Bluesky continuously and scores what it finds by relevance, engagement, and recency, and you open one feed instead of hunting. For the full workflow, tool or no tool, the 5-step system for finding customers on Bluesky walks through it end to end.

Bottom line

Threads wins on size and now sells you reach directly. Bluesky wins on what the traffic does once it gets to you, and it's the only one of the two where a small business can't be outspent.

Pick based on your model, not the follower count: awareness at volume, go Threads; qualified visitors and conversations that convert, go Bluesky. Then commit to one for ninety days before judging it, because both of these channels pay out on a slower clock than paid search.
