The ranking algorithm of Google and other search engines is based on the authority of the site, which is calculated using different formulas. In most cases, the metric is related to the quality of the link links.

Many years ago, webmasters evaluated donors based on PR. They checked Google PageRank and made decisions about link placement based on one indicator. The approach cannot be called optimal, but at least the optimizers had some official data that could be trusted.
1. What is Google PageRank
PageRank is an algorithm for determining the value of a page based on link connections. When Google's founders were just launching the search engine, they decided to focus on creating a quality content ranking algorithm and created PR.
Google PageRank has become the core of the content ranking algorithm. The model for calculating the metric is based on the approach used in the scientific world. When a scientist publishes a study and their work gets a lot of mentions in a short time, it confirms its quality.
A similar approach is used to content writing service
determine the weight of a page. If it has no links, then the algorithms evaluate only the content. Another page with minimal link connections can win the fight for high positions thanks to backlinks.
PageRank worked perfectly until webmasters started to inflate links everywhere. They realized that content ranking largely depends on the link mass and focused on buying links. Google had to make changes to the algorithm for determining the quality of backlinks.
1.1 Basics of the algorithm
The idea of calculating the importance of a page based on link connections looks promising even more than 20 years after Google was created. If you exclude any artificial boosts from the equation, it is enough to check the PageRank of a site to decide whether it is advisable to place links.
Google distributes link weight according to a specific algorithm, the details of which are not disclosed. PageRank is calculated using scores from 0 to 10 on a logarithmic scale. This means that there is a huge difference between pages scoring 8 and 10.
If you analyze the specifics of PageRank and do not delve into mathematical formulas, it becomes clear that everything is based on links. For example, if 20 donors link to page A of site #1, then the PR value will be calculated based on the quality of the sites with which the recipient has built link connections.
In such a situation, the project becomes dependent on other resources. If they lose authority over time, the weight of each link will decrease and this will affect the final PageRank value of the main site.
Currently, PR is not publicly displayed. You can only see historical values for old sites that some checkers have saved. But the information means nothing, since the value may have already changed and is known only to Google.
SEOs who want to increase their site's authority need to focus on getting links from high-quality donors. It's no longer useful to rely on PageRank, but each site needs to be carefully analyzed before integrating backlinks.
1.2. Brief history
In 1996, Google founders Sergey Brin and Larry Page were working on a research project that was the prototype of today's Google. They based their ranking algorithm on the idea of evaluating the quality of a page based on link connections.
The researchers realized that the simplest and most effective way to determine the importance of a page is the number and quality of links. If many authoritative sites link to it, then the content is useful and should be given high authority.
Using Google PageRank Checker, any optimizer could check the PR value until 2016. That's when the search engine removed the page quality value from public access, and stopped updating the indicator back in 2013.
Since then, Google representatives have repeatedly confirmed the webmasters' theory that Google PR is still one of the main components of the ranking algorithm. PageRank cannot be checked using the toolbar or extensions, but you can look at historical data for old sites.
There is no point in spending a lot of time searching for tools that will show the PR value. The data has not been publicly updated since 2013. There is no doubt that Google uses PageRank to evaluate the quality of a page, but the components of the formula may have changed long ago.
SEO services have developed alternative metrics, which in most cases are also tied to the quality of the link mass. They can be used to check potential donors and select the most authoritative sites from the list.
2. What influences the indicator
The PageRank of a page depends on the weight of the donors who link to it. The more trust they have in the eyes of Google, the higher the PR value will be. It is not possible to see the value of the metric now, but you can analyze the links and the quality of the donors to understand whether the page has a chance of good ranking.
It can be said that each link has a "voice", and it is desirable to get backlinks with the maximum level of "volume". Google is against link spam, so it is better to place 5 backlinks from authoritative sites than 500 from spammed resources.
Google PR has many alternatives, but they cannot be considered as ideal analogues. Since 2013, the search engine may have changed its approach to calculating the metric, and SEO services have their own methodology for determining the quality of sites.
A page's Google PageRank score is influenced by a large number of factors related to backlinks. When the values could still be viewed using the toolbar, they were updated periodically. Data on pages changes, and the PR value should not be constant.
It is worth considering that in the original formula, the PR value of a page depended on the number of links. If the content contained 20 hyperlinks, the total weight was distributed between them in equal proportions.
