No matter if you are in a product-centric business or a service-oriented business, as long as your target audience resides in Hong Kong, you have to act smartly to keep in touch with them and serve them efficiently. Since there are hundreds of other businesses offering the exact same services as you do, unless you opt for SEO HK, there is no way you can outrank them and grow your business. This is how most profit-making ventures in Hong Kong keep their leading positions intact. You should do the same to achieve the desired outcomes.
The problem with the traditional offline marketing is that you have to deploy all of your resources, and still there is no guarantee of reaching out to all of your target customers. On the other hand, when you use SEO properly, you can reach out to most of them in a short period. The best thing about online marketing and SEO is that even a single person or agency can help you connect with tens of thousands of potential customers. This is something traditional marketing can never do. So, keep your doubts aside and start using SEO immediately.
