What is Search Engine Optimisation?
Search engine optimisation (often called SEO) is a frequently mentioned phrase when talking about website design. In simple terms, SEO is making sure that your website is structured and written in a way that helps the search engines categorise your web pages to then return them to people searching for related content online.
Google's own Webmaster Guidelines offer a straight forward message - design your website for visitors, not for search engines. If your website pages are full of relevant and engaging content, and are well structured with use of good navigation, then this is the best way to improve how well your website performs in search results.
