How is Page Rank calculated?
Page Rank is calculated by the number/quality of links going to a site. Page Rank was the first algorithm at Google used to determine the search results. As it was widely abused by some SEOs to manipulate the results, Google have added many more intelligent algorithms. Link building is still a sound SEO technique though, and as long as you’re adding and gaining relevant, quality links, your Page Rank will go up and your organic listing will improve. Good content marketing and content amplification is one of the best ways to achieve this.
