Check Any Domain's Open PageRank

Open PageRank is a metric that measures the authority and importance of a domain based on the quantity and quality of links pointing to it. It uses an open-source implementation of Google's original PageRank algorithm, which was developed by Larry Page and Sergey Brin. The score ranges from 0 to 10, with higher scores indicating greater authority. The calculation considers factors such as the number of inbound links, the quality of linking domains, and the overall link structure of the web. Unlike proprietary metrics, Open PageRank's methodology is transparent and based on publicly available data from Common Crawl.

Our domain ranking database is updated regularly to reflect changes in the web's link structure. The Open PageRank dataset is recalculated periodically using the latest Common Crawl data, which captures billions of web pages. While exact update frequencies may vary, you can typically expect fresh data every few months. The "Last Updated" indicator on our statistics section shows when our current dataset was generated. For the most time-sensitive analyses, we recommend checking back periodically to track changes in domain rankings over time.

There are several reasons why a domain might not appear in our database. First, very new domains that haven't been indexed by Common Crawl yet won't have PageRank data available. Second, domains with extremely low traffic or very few inbound links may not meet the threshold for inclusion in the top 10 million domains. Third, some domains may have been recently registered or changed ownership, and the new data hasn't been captured yet. If you're checking your own domain and it doesn't appear, focus on building quality backlinks and ensuring your site is properly crawlable by search engines.
