In the world of SEO, you earn respect and authority by getting good content on your site and getting links from sites with high authority and good quality content.
As of now, PR ( Page Rank) does not matter for Google and has become obsolete. What does matter is DA(Domain Authority) and PA(Page Authority).
DA and PA are calculated based on the content that you have on your site. If you have good quality content, then you will see a boost in traffic to your site soon enough. And once people like your content, you will get good DA and PA.
If you have good quality content, then other sites are more likely to provide links to your site, and this is known as links. And if you get these links from good quality sites who have high DA and PA, then this is known as Quality links.
Hope it helps
