What is PageRank? Google PageRank Explained
PageRank is a numerical value that Google uses to determine how important a page is on the web. In other words, it is a link analysis algorithm that evaluates and measures the importance of your website and along with Search Engine Optimization, is one of many factors used by web marketing in determining where a webpage appears in search results.
Named after Google co-founder Larry Page, PageRank is largely based upon the number and quality of backlinks a webpage has. According to the Google founders, the most important pages on the internet are the ones with the highest number of links leading to them. Think of this as a voting scenario. Each link is a vote and by linking to a site, you are casting a vote. Although each link counts as a vote, pages with a higher PageRank value have more weight when “voting” compared to pages with lower PageRank. Another factor determined in PageRank is the number of links on the page casting the “vote.” Pages with more links have less weight.
PageRank is measured on a scale of zero to ten. Each individual page within a website is assigned a number, which means that an internal page have a high PageRank than your homepage. A page with a higher PageRank is considered more important in search results and is more likely to be listed above a page with a lower PageRank. Many online services contribute to great position in web searches and PageRank can only help your website increase in rank.
