There are three main types of SEO: Technical SEO, Content Creation, and Link Building. On-page SEO focuses on ensuring your website’s content is high quality, original, and well-written to rank well on search engine results pages. Off-page SEO involves building links to your site from high-quality websites, which helps it rank higher in search engine results. Mixed SEO combines both on-page and off-page strategies to create the best possible results for a website.
