What is Google PageRank?

The PageRank system is a set of algorithms used by Google to determine the web popularity of each of the pages that it adds to its index. In its search for objectivity, the PageRank system uses a complex secret equation of hundreds of millions of variables, the result of which is expressed as a numerical value on a scale of 1 to 10, an indicator that is automatically reassigned daily. This data is essential when determining the position of a page in the ranking of results of a query in Google .

To calculate it, Google assesses, among other data, the quantity and quality of incoming links; those that come from pages with a high PR will be better valued, while those tagged with the noFollow attribute are automatically discarded.

PageRank ceased to be public in 2016, but it does continue to update internally for Google and is losing weight in the algorithm.
