There are generally three types of SEO (Search Engine Optimization):
On-page SEO: This refers to the optimization of the elements on a website itself, such as the content, title tags, meta descriptions, images, headers, and internal links. The purpose of on-page SEO is to make the website more attractive to search engines and improve its ranking in search engine results pages (SERPs).
Off-page SEO: This refers to the optimization of external factors that affect the website's ranking, such as backlinks from other websites, social media engagement, and local business listings. Off-page SEO focuses on building the website's authority and reputation through external factors.
Technical SEO: This refers to the optimization of technical elements that affect the website's performance and indexing by search engines, such as site structure, mobile-friendliness, page speed, and security. Technical SEO aims to ensure that search engines can easily crawl and index the website's pages, and that the website is optimized for user experience.
