Search Engine Optimisation (SEO)

Search engine optimisation (SEO) is the process of improving the visibility of a website or a web page in search engines.

Search engines aim to provide users with a list of links to web pages that contain content relevant to the users' search terms. To do this, search engine software analyses web page content to determine how it should be indexed (for example, words are extracted from the page titles, headings and body content) in relation to likely search terms.

Websites that are well-structured, accessible and use valid HTML are ranked higher in search results.
