This is a metric developed by Google to measure the importance of website pages. It gives to websites a score between 0 and 10. A high PageRank score helps websites to rank higher in search results. This score is calculated based on the number and quality of backlinks on a website. Getting backlinks from websites with high PageRank scores is especially important for receiving a high PageRank score. Because of this, after the introduction of the PageRank algorithm, some webmasters resorted to Black Hat SEO methods. After an increasing number of webmasters manipulated the algorithm and started selling links, Google stopped rolling out updates for the PageRank algorithm. Therefore, today, webmasters take into account the estimated scores that different tools give to their websites.
