There are three core types of SEO—on-page, off-page, and technical SEO.
On-page SEO refers to the process of optimising website pages through content placement, images, title tags, meta data, and more, to improve visibility and traffic.
Off-page SEO involves taking steps outside of the website, such as improving popularity, relevance, and authority, as well as establishing high-quality backlinks to increasing search engine rankings.
Technical SEO requires you to optimise both your website and your server through improving page speed, site structure and core web vitals, as well as incorporating mobile-friendly fea- tures to make it easier for search engine spiders to crawl and index your site, thus improving your performance.
