What Are the Main Types of SEO?

There are four main types, and a complete strategy uses all of them. On-page SEO covers the content and structure of each page, including titles, headings, keywords, and internal links. Technical SEO makes sure Google can crawl, index, and load your site quickly. Off-page SEO builds authority through backlinks and mentions from other trusted websites. Local SEO helps you appear in Google Maps and near-me searches for customers in your area. Some people add content SEO as a fifth, though I treat it as part of on-page. The point is that these are not separate services competing with each other. They are layers, and weakness in one limits the results of the others.
