Search Engine Optimisation (SEO), or optimization in the USA, are the techniques used to help a website rank near the top, or best of all number 1, in the organic search engine results for a particular search term.

Organic results are the results listed and ranked by search engines as opposed to the sponsored listings paid for by advertisers - most search engines display these above or at the side of the organic search results.

The good news is you can get to the top of the organic results for free if you are prepared to put a bit of work in and do your own SEO.
