To have a website at the top of the results into a search engine and keep it well positioned it is essential to optimize
and understand, first, a search engine is something that is alive. Obviously this does not mean that search engines have a brain, I leave those tales to Orson Scott Card and other writers of science fiction, however, their true nature lies in human behavior with much more capacity storage. If one considers a moment how a search engine, he sailed around the world, following the signs and the roads to go where it has to do and it collects all
information on its way. From there, information is returned on a group of servers or
algorithms are applied to determine the importance of specific documents. How do these algorithms have been generated? They were created by people who have great experience in understanding the fundamentals of the Internet and its contents and also have the ability to learn from their mistakes and then to update the algorithms accordingly. Essentially we have an entity that collects data, stores, and then sorted in order to determine what is important, which is happy to share with others and what is not important and should be rejected.
