Search engine optimisation (SEO also spelt search engine optimization) is the process of editing and organizing and revising the words and content on the web pages throughout a website to maximise the relevancy of specific keywords and key phrases on the major search. The reason this is carried out is to achieve a higher organic search listing which in turn increases the volume of traffic from search engines due to more visibility and exposure to people searching for you.
SEO is one of the most integral website marketing activities to increase the performance of a website.
SEO also involves a consideration for how search engines rank websites and also what people search for.
Optimising a website involves editing the content and also the HTML code of a website to make the pages highly relevant to what people search for but also so it is easily searchable by search engines themselves. It is very important that the webpages are structucted using efficient and accurate code to ensure search engines can easily move right throughout the website. Badly coded websites present obstacles and barriers that search engines do not like.
SEO is often taken too far to the detriment of website rankings. Some techniques, known as black hat SEO or Spamdexing, use methods such as link farms and keyword stuffing that actually degrade both the relevance of search results and the user-experience of search engines. Search engines look for sites that employ these techniques in order to remove them from listings.
It is critical that your website is search engine friendly. The term 'Search engine friendly' refers to a website that has been search optimised.
