Curious about what is my Google PageRank? PageRank is one of the most recognized concepts in the history of search engine optimization. Originally developed by Google to help evaluate the importance of web pages, it used the relationship between links to estimate the authority of pages across the web. While the old public PageRank score is no longer provided as a live Google metric, checking PageRank-related information can still be useful for understanding the history of a domain and the development of link-based SEO.
