The term “ search engine optimization ” means making a web site easy and  properly read and indexed by search engines such as Google,Yahoo,MSN, etc. ‘True’ Search Engines send computer programs known as “spiders” or “robots” to scan your website.The SEO specialist’s task is to understand how to present these spiders with the information they are looking for in order for the search engines to determine the value of your web site.Search engine optimisation success is largely dependant upon the keywords required. Only intelligent keyword choices, well written source code and relevant content presented clearly to both the user and search engine alike will achieve good, long term results.
