KOL platforms in Hong Kong come down to six: Instagram, Facebook, Threads, TikTok, YouTube and Xiaohongshu. Instagram is the main platform for brand collaborations. Facebook reaches older and community audiences, Threads drives conversation, YouTube suits in-depth reviews, TikTok suits short-video trends, and Xiaohongshu reaches mainland visitors. Pick the platform where your customers already spend time and where your product is easiest to explain, not simply the biggest one.

"Official API data" means creators link their accounts through the platform's official authorization, so brands on Connector Club see data supplied directly by the platform. "Practical know-how" means we share what we have learned about collaborating there, but we don't provide data, tracking or verification on that platform.
Audience size by platform in Hong Kong
According to DataReportal's Digital 2026: Hong Kong report, Meta's advertising tools showed an ad audience of about 4.70 million for Facebook in Hong Kong at the end of 2025, about 4.05 million for Instagram and about 1.55 million for Threads. YouTube's ad audience was about 6.24 million. These are ad reach figures, not monthly active users, but they show the relative scale: Facebook and Instagram reach the most people, while Threads is smaller but conversation-heavy.
How to choose a KOL platform
Five questions to answer first
- Who is your audience? Younger women lean to Instagram, older audiences to Facebook, mainland visitors to Xiaohongshu.
- How long does your product take to explain? If one picture says it, use an Instagram post. If it needs a demo or comparison, use Reels, YouTube or Facebook video.
- Is the goal reach, conversation or sales? Reach: Instagram and Facebook. Conversation: Threads. Search-led buying decisions: YouTube and Xiaohongshu.
- Do you need reliable data? If you must track results and report on them, favour platforms with official API data.
- What is your budget? Rates vary widely by platform and format. Try the KOL rate estimator.
Most brands use more than one platform. A common mix is Instagram for core reach plus Threads to get people talking, or YouTube for in-depth reviews. When the main platform has official data, your report rests on a solid base.
