PageRank,
PageRank is a system for ranking websites that Google founders Larry Page and Sergey Brin developed at Stanford University. And it's important to understand that PageRank is all about links.

The more PageRank a link has, the more authority it has.

We can simplify the PageRank algorithm by describing it as a way of measuring the importance of a website by analyzing the quantity and quality of the links pointing to it.

The PageRank index
As you might expect, PageRank is a complex algorithm that assigns an importance score to a website page.

But as far as day-to-day SEO is concerned, PageRank was a linear representation of an algorithmic scale between 0 and 10 that was previously displayed in the PageRank toolbar.

A PageRank score of 0 is typically attributed to a low-quality kazakhstan mobile database website. On the other hand, a score of 10 would represent only the most authoritative websites on the entire Internet.

The key to understanding PageRank scores is that it uses a logarithmic scale. Not sure what this means?

A logarithmic scale is a way of displaying numerical data over a large range of values ​​in a compact form, typically with the largest numbers being hundreds or even thousands of times larger than the smallest numbers.

As Search Engine Watch reported , "It has an estimated base of 4-5." In other words, assuming a base of 5, PR2 links are comparable to 5 PR1 links; a PR6 link is comparable to 5 PR5 links, and so on."

Clearly, we can see that a PR10 link is comparable to thousands of PR1 links.
