Pagerank

Definition

PageRank is an algorithm used by search engines to rank web pages in their search results. It assesses the importance of a page based on the number and quality of links pointing to it, with the idea that more important pages are likely to receive more links from other websites. This approach helps enhance information retrieval by prioritizing higher-quality sources in search results.
