The cost of international SEO can vary widely depending on the complexity of the project, the number of countries and languages you’re targeting, the current state of your website, and the agency or professional you choose to work with. Some SEO agencies might charge an hourly rate, which can range from $50 to $200 per hour or more. Others might charge a monthly retainer, which could range from a few hundred dollars to several thousand dollars per month. Remember that international SEO is a significant investment that involves not just translation, but also localization of content, keyword research for each target market, technical SEO setup for each language version of your site, and building local links. All of these tasks require a significant amount of time and expertise, which is reflected in the cost.
