PageRank is a system developed by Google’s co-founders, Larry Page and Sergey Brin, to rank web pages in search engine results. It was one of the original algorithms that helped determine the importance of a page based on the number and quality of links pointing to it. Though PageRank is no longer the sole or even primary factor in Google's ranking algorithm today, understanding it can still be useful for grasping the fundamentals of SEO and link evaluation.
How PageRank Works
Link Analysis: PageRank works on the principle that a link from a high-quality or authoritative page is more valuable than a link from a low-quality or less authoritative page. Essentially, it measures the quantity and quality of inbound links to a page.
Link Voting: Each link to a page is considered a "vote" for that page. A page with many high-quality votes will generally rank higher than a page with fewer votes or votes from less authoritative sources.
Rank Distribution: PageRank is calculated iteratively. It distributes the rank of each page to the pages it links to, with the rank being proportional to the rank of the linking page.
Tools to Check PageRank Online
**PageRank Checker Tools: While Google has officially retired the public PageRank score, some third-party tools and services offer estimations or historical data related to PageRank. Examples include:

Ahrefs and SEMrush: These tools provide insights into the strength and quality of backlinks, which can be correlated with PageRank concepts.

Google Search Console: Although it doesn’t provide PageRank directly, Google Search Console can help you understand how your site is performing in search results, which indirectly reflects your site’s authority and link profile.
Current Relevance
PageRank is now just one of many factors in Google's ranking algorithm. Today, Google’s ranking system incorporates hundreds of signals, including content relevance, user experience, mobile-friendliness, and more. While PageRank gave a good foundation, modern SEO requires a more holistic approach.
If you're interested in monitoring your website's authority or performance, consider focusing on metrics like:
Backlink Profile: The quality and quantity of links pointing to your site.
Content Quality: Relevance and value of the content on your site.
User Engagement Metrics: Metrics like bounce rate, average session duration, and click-through rate (CTR).
Understanding these factors will give you a better grasp of how well your site is likely to perform in search results today.
