Referrer or Referrals in web analysis

In web analysis, Referrer or Referral(s) is the web page through which a visitor came to the current page.

An Example: A visitor is on a blog post with the URL "https://365-sunflower-competition.com/blog/21.competition/" and clicks on a link to our page https://tracking-garden.com .
Then we measure the Pageview of this visitor on our site (tracking-garden.com). The reference of this Pageview on our site is then "https://365-sunflower-competition.com/blog/21.competition/".

In Google Analytics, the References report can be found under [ Acquisition / All Traffic / Referrals ]:
