Do follow link example: <a href="https://www.newexample.com/url">Other Webpage</a>

By default hypertext links are do follow links. 

From do follow link, crawlers from search engine assume both the webpage (the webpage which contains hypertext link and the url of the linked webpage) are related.

Which is the top factor in 2019 that Google notices first to rank a website?

The top factor that Google notices first to rank a website is the bounce rate. 100% bounce rate means the website is not user friendly and is not beneficial to user in a broader sense. 0% bounce rate means the website is super beneficial for users.
