Threads Ads: What Hong Kong Advertisers Need to Know (2026)

Threads crossed 300 million monthly users faster than almost any consumer app in history — and through 2025, Meta quietly switched on the part advertisers care about: ads. For Hong Kong businesses already running Facebook and Instagram campaigns, Threads is now a placement you can reach with the tools you already use. The honest question isn't "can I advertise on Threads?" — it's "should I, yet?" Here's what we tell clients.

How big is Threads, really?

Meta reported that Threads passed 300 million monthly active users in late 2024, and the app has kept growing since. That makes it one of the fastest-growing social platforms ever launched.

Two things Hong Kong advertisers should keep in mind:

• Hong Kong is no longer a data blank. Per DataReportal's Digital 2026: Hong Kong, citing Meta's own advertising tools (as of Q4 2025), Threads reaches roughly 1.55 million people in Hong Kong — about 21% of the total population and around 23% of adults aged 18 and over. Hong Kong and Taiwan are in fact the two highest adult-reach markets for Threads globally, with HK penetration sitting above the worldwide average.
• But be precise about what that means: 1.55 million is ad reach, not daily active users. Threads accounts are created off the back of Instagram, so the figure reflects how many people Meta can serve ads to — it overstates real daily usage. The active base is still smaller than Facebook and Instagram, but it's large enough for Hong Kong brands to test properly. As for what it actually delivers, we've verified that with our own data (see the placement comparison below).

How Threads ads actually work

The most important thing to understand: Threads is a placement, not a separate ad platform. You don't open a "Threads Ads Manager" — there isn't one.

• Ads are bought through the same Meta Ads Manager you already use for Facebook and Instagram.
• Meta began testing ads on Threads in early 2025 and opened the placement to advertisers globally over the course of the year. Image ads in the Threads home feed came first; expect the format list to keep evolving.
• Targeting, audiences, the Pixel and the Conversions API all carry over — Threads inherits the whole Meta stack. There is no separate "Threads audience" to build.
• If you run Advantage+ placements (Meta's automatic placement setting), your ads may already be appearing on Threads without you having chosen it. Check your placement breakdown before assuming you've never run a Threads ad.

Should Hong Kong advertisers put money into Threads now?

Our honest take, based on how early placements usually behave:

The case for trying it:

• Early inventory on a new placement is usually cheap. Fewer advertisers competing means lower CPMs than the equivalent Facebook or Instagram feed impression.
• It's nearly zero extra work. Because it's a placement inside campaigns you already run, testing Threads costs you a checkbox, not a new campaign build.
• Early-mover brand presence: if your audience skews younger and content-native, being visible on a platform before your competitors has real value.

The case for caution:

• Cheap reach is not the same as buying intent. Threads usage is conversational and interest-led; nobody is searching for a plumber or comparing clinics there. Treat it as awareness inventory, not demand capture.
• Measurement is placement-level, not platform-level. You'll see how Threads impressions performed inside a campaign, but building a Threads-only funnel doesn't really exist yet.
• Formats are still maturing. What's available today may look different in six months — don't over-invest in creative built for one specific unit.

Our house view: for most Hong Kong SMBs, Threads is a bonus, not a pillar. Get your Facebook and Instagram fundamentals right first — creative testing rhythm, proper tracking, a landing page that converts. Then let Threads ride along via Advantage+ placements and judge it from the data. It is not a substitute for Search when you need enquiries this month.

How to turn it on

1. In Ads Manager, create or edit a campaign as usual.
2. At the ad set level, go to Placements. With Advantage+ placements on, Threads is included automatically where eligible. For manual placements, tick Threads in the placement list.
3. Use creative that stands alone: Threads is a text-first feed, so overlays and captions carry more weight than polished key visuals.
4. Keep the destination consistent — the click still lands on your website or WhatsApp flow, so the message match rules that apply to IG apply here too.

How to measure it

Don't judge Threads with a feeling — segment it out:

• In Ads Manager reporting, use Breakdown → Placement to isolate Threads impressions, clicks and conversions.
• Compare cost per result against your Facebook feed and Instagram feed placements, not against Search — different jobs.
• Give it enough volume before deciding. A few hundred impressions tells you nothing; revisit after a full campaign cycle.

Here are the relative numbers from our own test, indexed to Facebook = 100 (relative comparison, not absolute cost):

Threads swept all three — cheapest CPM, cheapest CPC, highest CTR — the low-competition dividend of a new placement. But remember this is awareness data: cheap reach is not purchase intent, still a top-of-funnel signal.

If Threads consistently delivers cheaper results at acceptable quality, let it keep its budget share. If it soaks spend with no results, exclude the placement — one checkbox again.

FAQ

Can Hong Kong businesses run Threads ads? Yes. Threads ads are bought as a placement through Meta Ads Manager, which is fully available to Hong Kong advertisers — there is no separate platform or approval process beyond normal Meta ad policies.

How much do Threads ads cost? There is no fixed price — Threads inventory is bought in the same auction as your other Meta placements. Early placements typically clear at lower CPMs than Facebook or Instagram feeds because fewer advertisers compete for them, but costs vary by audience and season.

What's the difference between Threads ads and Instagram ads? Same buying system, different surface. Threads is a text-first conversational feed, so ads lean on copy and standalone visuals; Instagram is visual-first. Targeting, tracking and reporting are shared through Meta Ads Manager.

Do I need a Threads account to advertise there? You run ads from your existing Meta business assets. Having an active Threads presence helps context and credibility, but the ads themselves are served through Ads Manager placements.

Is Threads worth it for lead generation in Hong Kong? Not as a primary channel. Threads reaches people in a browsing mindset, not a searching one. Use it for low-cost awareness alongside Facebook and Instagram, and keep demand capture on Search.
