The cost of SEO services varies depending on the scope of the work. Because SEO is such a specialized field, requiring an expert level of skill and expertise to be effective, the average monthly retainer for an agency can range from HK$15,000 to HK$80,000.

However, these figures aren’t precise because any SEO agency quote will be incumbent upon the extent and nature of the work your website needs to reach your SEO goals and outcomes.
