The content is formatted and written in such a way that the reference word search would make the website appear in the top most results. This does not involve stuffing the site with important words as the entire search engines have mechanism to deal with these kinds of fake exercises. The other part revolves around the web development of a website and the program that is included in the back end and the data base. Usually the web programmers write the code in such a way that the link to the site from the search engine is the fastest to be accessed and to appear on the search page. Different codes use various kinds of ranking algorithms in their code in order to match with the search engine's sorting techniques. These algorithms are not revealed for unbiased monitoring and quality purposes. Theoretical and practical developments are taking place every day in this field.
