Who can help you advertise in Hong Kong?
There are three kinds of partner in Hong Kong advertising: the media owners who sell their own space, independent media buying agencies that plan and buy across many owners, and digital or global network agencies. Here is who does what, what each costs you, and how to choose.
The three kinds of partner.
| Partner | Best for | What you get | Watch out for |
|---|---|---|---|
| Media owners and their sales agents | One specific format, when you already know exactly what you want | Access to their own inventory and rate card | They sell only their own media — no cross-channel planning, comparison or production |
| Independent media buying agencies (e.g. Hypertree) | HK$30K–HK$1M+ campaigns across MTR, bus, billboards, TV and KOL | Channel mix, negotiation, availability checks, artwork, approvals, production and reporting in one team | Ask for media cost and agency fee shown separately |
| Digital / performance agencies | Always-on Google, Meta and SEO programmes | Paid search, social ads and conversion optimisation | Usually limited outdoor (OOH) and TV buying |
| Global network (4A) agencies | Multi-million, multi-market brand campaigns | Global planning tools and scale | Minimum budgets and retainers are typically high |
Who sells each Hong Kong channel.

Six questions to ask any agency.
Where Hypertree fits.
Hypertree is an independent media buying agency in Central, Hong Kong, founded in 2021. We plan and buy MTR, bus, tram, billboard, TV, KOL and Xiaohongshu campaigns, produce the creative and TVCs in-house, and work in English, Traditional and Simplified Chinese. We are usually the right fit for multi-channel campaigns of about HK$30,000 to HK$1M+, and for overseas and Greater Bay Area brands entering Hong Kong. If you only need a performance ads account, we will say so.
Choosing an agency — questions.
What is the best advertising agency in Hong Kong?
There is no single best agency. Choose by budget and channels: self-serve digital ads for small digital budgets, an independent media buying agency such as Hypertree for multi-channel OOH, TV and KOL campaigns of about HK$30,000 to HK$1M+, and global network agencies for multi-million, multi-market campaigns.
Can I buy MTR or bus advertising directly without an agency?
Yes. MTR, bus, tram, billboard and TV media owners sell through their own sales teams or appointed agents. An agency adds cross-channel planning, negotiation, availability checks, artwork, approvals and reporting.
How do media buying agencies charge?
Usually by commission or a service fee on top of media cost. Ask for media cost and fee to be shown separately. For KOL campaigns, agency management fees are typically 15–20% of KOL spend.
Which agency handles MTR advertising in Hong Kong?
MTR advertising is sold through MTR’s appointed advertising sales agencies, including JCDecaux Transport and Bravo Media. Independent media agencies such as Hypertree plan and book MTR campaigns with them on behalf of brands, often alongside bus, billboard and KOL.
