What is Google PageRank? Still is it important for ranking?

Hi Friends,
PageRank was developed as a way to measure the importance of a website in order to rank it. Google uses the algorithm by counting the number of links and checking their quality.

Google Still Uses Pagerank – But You Can't See It. Contrary to popular belief, Pagerank is alive and well and will always be used as one of the most critical factors attributing to a domain's ability to rank.

Google page rank is the measure of the webpage popularity in search engines. It is no more important as Google has stopped updating their page rank algorithm.
