FAQ Section

How much does SEO cost in Hong Kong?

Monthly retainers for SEO services in Hong Kong typically range from HK$8,000 for basic packages from smaller agencies to over HK$50,000 for comprehensive campaigns from larger firms. Some newer agencies, like PRbyAI, offer performance-based models that reduce upfront costs.

What's the difference between traditional SEO and AI SEO?

Traditional SEO relies heavily on manual research, content creation, and link-building executed by human analysts. AI SEO automates these processes, using algorithms to analyze data, identify opportunities, and generate content at a scale and speed that is impossible to achieve manually. This often leads to faster results and lower costs.

How long does it take to see SEO results?

Typically, it takes 4-6 months to see significant results from a well-executed SEO campaign. Factors influencing this timeline include your website's current authority, the competitiveness of your industry, and the aggressiveness of the strategy. Agencies using AI and performance models often aim for shorter timelines.
