The four main types of SEO are on-page SEO, off-page SEO, technical SEO, and local SEO.
On-page SEO involves optimising the content and HTML elements of your website pages. Things like keyword placement, headers, meta tags, and internal linking.
Off-page SEO focuses on building your website’s authority through external signals, most importantly backlinks from other reputable websites.
Technical SEO covers the behind-the-scenes health of your website, including site speed, mobile-friendliness, crawlability, Core Web Vitals, and structured data.
Local SEO is specifically aimed at businesses serving a geographic area, and involves optimising your Google Business Profile, building local citations, and targeting location-specific search terms.
A well-rounded SEO strategy addresses all four types, though the emphasis will differ depending on your business model and goals.
