Google PageRank
The PageRank is a value between 0 and 10 (0=bad, 10=very good), which, in simple terms, expresses the degree of interconnectedness of a website or how well it is integrated into the web. PageRank is calculated using an algorithm that was patented by Google co-founder Larry Page back in 1997.
PageRank became publicly available in 2000, enabling website operators to determine their PageRank.
In the following years, SEO optimisers pounced on this PageRank. Everything was done to improve / increase it. As a rule, the PageRank could be influenced by a high number of external links pointing to a website. The higher the "quality" of the page linking, the more significant the backlink. The more good quality links pointing to a website, the higher the PageRank of the page being linked to.
The Google PageRank is no longer publicly visible
For some years now, the PageRank of a website is no longer publicly visible.
However, this does not mean that PageRank no longer plays a role. PageRank should still play an important role. However, as before, other important SEO factors are added. In my opinion, "Content is King" still applies (This quote originally comes from an essay by Microsoft founder Bill Gates, which he wrote back in 1996).
Personally, I find the abolition of the public visibility of PageRank positive, especially since a good positioning of a website in the search engines requires more than just a high PageRank. All in all, all website operators should care less about PageRank and more about producing useful content.
