Once SEO is explained to you, you will see that search engine optimisation (SEO also search optimisation) is the process of editing and organising the content on a webpage or across a website to increase its potential relevance to specific keywords on specific search engines. This is done with the aim of achieving a higher organic search listing and thus increasing the volume of traffic from search engines.
SEO is one of the key Web Marketing activities and can target different kinds of searches, including image search, local search, and industry-specific vertical search engines.
SEO considers how search engines work and what people search for. Optimising a website primarily involves editing its content and HTML coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Sometimes a site’s structure (the relationships between its content) must be altered too.
Because of this it is, from a client’s perspective, always better to incorporate Search Engine Optimisation when a website is being developed than to try and retroactively apply it.
Another class of techniques, known as black hat SEO or spamdexing, use methods such as link farms and keyword stuffing that 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 their indices.
The term ‘Search engine friendly’ refers to a website that has been search optimised. Now you should never need to have SEO explained to you again!
