The Question Everyone Googles
"How much should I spend on marketing?" is one of the most searched marketing questions in Hong Kong. The generic answer — "5–10% of revenue" — is useless because it doesn't account for business stage, industry margins, or growth goals.
Here's a practical framework based on real HK market data.
Budget by Revenue Stage
Pre-revenue or under HK$500K annual revenue
Marketing budget: HK$5,000–15,000/month. Focus 100% on one paid channel (usually Meta Ads). Don't split budget across channels at this stage — you don't have enough spend to generate statistically meaningful data on multiple platforms.
Minimum viable spend for Meta Ads in Hong Kong: HK$200/day (HK$6,000/month). Below this, the algorithm doesn't receive enough conversion data to optimise effectively.
HK$500K–2M annual revenue
Marketing budget: HK$15,000–50,000/month (roughly 8–12% of revenue). Add a second channel — Google Search Ads if you have search demand, SEO if you're playing the long game. The split should be 60–70% on your primary channel and 30–40% on the secondary.
HK$2–5M annual revenue
Marketing budget: HK$40,000–120,000/month (6–8% of revenue). Three or more channels become viable. Add SEO and content marketing as a long-term play. Invest in email marketing infrastructure. Consider hiring a junior marketing hire to manage day-to-day execution.
Above HK$5M annual revenue
Marketing budget: HK$80,000–250,000+/month (5–7% of revenue). Full-channel strategy: Meta, Google, SEO, email, WhatsApp, potentially YouTube. At this scale, the marginal cost of adding channels decreases and the compounding effects of multi-channel presence kick in.
Minimum Viable Spend by Channel
Meta Ads: HK$6,000/month minimum. Below this, you won't exit learning phase or get meaningful conversion data.
Google Search Ads: HK$5,000/month minimum. Depends on keyword CPCs in your industry — legal and finance verticals may need HK$15,000+ minimum.
SEO: HK$8,000/month minimum for agency services. Below this, the scope is too limited to move rankings meaningfully.
Email marketing: HK$500–2,000/month for platform costs. The real investment is time spent on list building and content creation.
WhatsApp Business API: HK$500–2,000/month for the API platform plus per-conversation costs of HK$0.20–0.50.
The Payback Period Reality
Most HK businesses expect instant returns from marketing spend. Here's the realistic timeline:
Meta Ads: 2–4 weeks to exit learning phase. 30–60 days to optimise for profitable ROAS.
Google Search Ads: 1–2 weeks for initial results. 30 days for meaningful optimisation data.
SEO: 4–8 months for first page rankings. 6–12 months for meaningful organic traffic.
Email: Immediate ROI if you have a quality list. 3–6 months to build a list from scratch.
The rule of thumb: budget for at least 90 days of spend before evaluating whether a channel is working. Killing a campaign after two weeks because "it's not working" is the most expensive mistake HK business owners make.
Bottom Line
There is no universal answer to "how much should I spend." But there is a framework: start with 8–12% of revenue, concentrate on one or two channels, track CAC and ROAS monthly, and scale what's profitable. The businesses that treat marketing as a measurable investment — not a cost — are the ones that grow.
