Search engine optimisation is often presented as a collection of separate techniques, from using the right keywords to improving page speed. In practice, successful SEO depends on several interconnected elements working together.
Search Engine Land’s Periodic Table of SEO Elements provides a useful framework for understanding these foundations. It groups the most important elements into seven areas: content, architecture, code, credibility, links, user experience and performance.
High-quality, relevant content remains central, but content alone is not enough. A website must also be easy for search engines to crawl and understand, with clear titles, headings, descriptions and structure. Credibility matters too: demonstrating genuine experience, expertise, and trustworthiness can strengthen both reputation and visibility.
Links help users and search engines discover related information, while factors such as accessibility, search intent and task completion contribute to a better user experience. Technical performance—including speed, responsiveness and mobile-friendly design—ensures that visitors can access and use the content effectively.
The key lesson is that no single SEO technique guarantees success. Sustainable visibility comes from creating useful content, organising it clearly, building trust and offering a consistently good experience.
