Every existing web page is ranked by Google on their search engine. The rank is given depending on page’s authority. The most important factor when it comes to ranking a page are the links connected to it. Both their quality and amount are taken into account. Other factors influencing the page ranking include traffic, site’s age and other data concerning the site.
When a new web page is linked to an existing one, it inherits the Page Rank. This process is known as passing link juice. If you do not want a site to pass its Page Rank to a newly created one, the ‘nofollow’ tag can be used.
