What Is PageRank Alogrithm ?
PR Alogrithm is a calculation, famously invented by Google founders Larry Page and Sergey Brin, which evaluates the quality and quantity of links to a webpage to determine a relative score of that page’s importance and authority on a 0 to 10 scale.
how can backlinks help or hurtThe handful of PageRank 10 domains, including USA.gov, Twitter.com and Adobe Reader Download, have the highest volume of inbound links of any sites on the web.
The top sites set the bar, so to speak, and the 10-point scale plummets exponentially down from there.
PageRank 5 websites have a good number of inbound links, PR 3 and PR 4 sites have a fair amount, and brand new websites without any inbound links pointing to them start at PageRank 0.
NOTE: You may be curious what your site’s or your competitor’s PR score is. But Google no longer reveals the PageRank score for websites. It used to display at the top of web browsers right in the Google Toolbar, but no more. And PR data is no longer available to developers through APIs, either. Even though it’s now hidden from public view, however, PageRank remains an important ingredient in Google’s secret ranking algorithms.
Since Google wants to return page one results that are high quality, relevant, and trustworthy, it may return webpages with better PageRank scores higher up in the SERPs, although PageRank is only one of many ranking factors taken into consideration.
Since PageRank is only one factor in the Google ranking algorithm, it’s important to remember that a high PageRank does not guarantee high rankings — but it can significantly help.
