There is no official API for Google PageRank, but you can estimate it using various tools and libraries such as:

  1. Using a PageRank checking tool: There are various websites that offer PageRank checking services. You can use these tools by passing the URL of the website as a parameter and the tool will return the PageRank.
  2. Using a PageRank API: Some websites offer PageRank APIs that can be used to programmatically retrieve the PageRank of a website.
  3. Implementing PageRank algorithm: You can also implement the PageRank algorithm yourself and calculate the PageRank of a website. The algorithm involves a large matrix computation and requires a lot of processing power.


Please note that Google no longer updates PageRank scores and it is not a reliable metric to measure the importance of a website. Alternative metrics such as Domain Authority (DA) and Page Authority (PA) offered by Moz, Alexa Rank, and the number of backlinks can be used as a substitute.

As of this response's timestamp in May 2022, Google has officially discontinued the PageRank metric. It is no longer publicly available and cannot be retrieved programmatically.


However, if you are specifically looking for the PageRank algorithm implementation, you can refer to academic papers and research studies that explain the algorithm. One such paper is "The Anatomy of a Large-Scale Hypertextual Web Search Engine" by Sergey Brin and Lawrence Page, the creators of the PageRank algorithm.


To implement the algorithm, you will need to build a web graph representing the connectivity between web pages and perform iterative calculations to estimate the PageRank scores. This involves matrix operations and updating the scores based on incoming links. Libraries like NetworkX in Python can be helpful for graph-based computations.


Keep in mind that implementing the PageRank algorithm may not provide the same results as the original Google PageRank, as Google utilized many additional factors and signals, beyond the basic algorithm, to determine the ranking of web pages.

That's correct! Thank you for the clarification. As of May 2022, PageRank is no longer publicly available or accessible programmatically from Google. It is no longer considered a reliable metric for evaluating the importance or ranking of websites.


Instead, you can consider alternative metrics provided by other services, such as the aforementioned Moz's Domain Authority (DA) and Page Authority (PA), Alexa Rank, or other backlink-based analysis tools. These metrics can give you an idea of a website's relative authority and popularity.


It's worth noting that, while these alternative metrics can provide some insights, they are not direct replacements for Google's PageRank algorithm, which considered various factors and signals to determine rankings.
