The cost to improve technical SEO can vary depending on the scope of work and the complexity of the website. Simple technical SEO improvements, such as fixing broken links, optimizing images, and improving site speed, may cost a few hundred dollars to a few thousand dollars, depending on the size of the website and the level of optimization needed. More complex technical improvements, such as site migration, information architecture overhaul, or advanced schema markup, may cost several thousand dollars to tens of thousands of dollars. The cost of technical SEO improvements can also depend on whether the work is being performed in-house or by an external agency. It’s important to assess the value and potential return on investment of technical SEO improvements before committing to a provider and to ensure that the provider uses ethical and effective SEO techniques that comply with search engine guidelines.
