In olden days, users started to practise keyword stuffing by adding too many keywords in the web page and in the blank space inorder to obtain high rank. Later google introduced link specific that means those who have more links in the page achieve high ranks so, users tried to add maximum number of links to raise the ranking. Due to this, the quality of the website decreased. Thus google put forward quality link specific . 

 Here ,quality content is the important driver to the search engine and ranking is based on quantity and quality of links to the website and it is valued based on the scale 0-10 .  Only few website  have rank 10 for instance , US govt site.
