What is SEO?
Search engine optimisation: the work of helping the right people find you in search, by making your site fast, clear, well-structured and genuinely useful.
SEO stands for search engine optimisation: the practice of improving how easily people find your website through search engines like Google, and increasingly through AI answers and assistants.
The three sides of it
- Technical SEO. The foundations: a site that loads fast, can be crawled and indexed, works on mobile, and uses structured data so machines understand it.
- On-page SEO. The content: clear, helpful pages that answer real questions, with sensible titles, headings and internal links.
- Off-page SEO. The reputation: other credible sites referencing and linking to yours.
It’s not tricks
Good SEO isn’t keyword-stuffing or gaming an algorithm. Search engines are trying to reward pages that genuinely help the person searching. The most durable SEO strategy is to be the most useful answer to a question your customers actually ask, then make sure the site is fast and structured enough for that usefulness to be found.
SEO and AI search
The same fundamentals of clarity and real expertise are what help AI assistants surface and cite your business too. A glossary like this one is a long-term play: every article answers one question, building a body of work that both people and machines can draw on.
