What are the three types of SEO services?

The three types of SEO services are on-page SEO, off-page SEO, and technical SEO. On-page SEO focuses on optimizing the content and structure of a website, such as keywords, headings, and meta tags. Off-page SEO builds authority through backlinks and external signals. Technical SEO ensures that search engines can crawl, index, and understand a site by improving speed, mobile usability, and security. Together, these services form the foundation of optimization, with subcategories such as local SEO, ecommerce SEO, and enterprise SEO addressing specialized needs.
