What is Google PageRank, and is it still relevant?

PageRank is an algorithm developed by Google founders Larry Page and Sergey Brin to measure the importance or relevance of web pages. It assigns a numerical value to each webpage based on the quantity and quality of links pointing to it. The idea is that pages with higher PageRank scores are more likely to appear at the top of search engine results, indicating their authority and credibility.

While Google's ranking algorithms have evolved over time, PageRank still plays a significant role in determining search results. However, the exact workings of PageRank are no longer publicly disclosed, and Google now uses numerous other factors in combination with PageRank to deliver more relevant search results.

Additionally, Google has stated that they no longer update or publicly display the PageRank score for web pages, making it less visible to website owners and marketers. Nevertheless, the essence of PageRank, which is assessing the importance of a page based on its link profile, continues to be relevant as one of many aspects affecting ranking and visibility in search engine results.
