Operational mechanisms of search engines

A first basic facts you need to know that the Google search engine is not human. Therefore, there will be differences between humans and search engines in assessing the content of a web page. Unlike humans, search engines content oriented. Although search engines are equipped with very modern technology but it still was not smart enough to be able to feel the beauty of a design, enjoying the sound or see the movement of a video dirty.
