By checking the referrer, the server providing the new web page can see where the request originated.

PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites.
- Currently, PageRank is not the only algorithm used by Google to order search results, but it is the first algorithm that was used by the company, and it is the best known. As of September 24, 2019, all patents associated with PageRank have expired.
Notes
From the point of view of a given web resource (referent), a backlink is a regular hyperlink on another web resource (the referrer) that points to the referent. A web resource may be (for example) a website, web page, or web directory.
A backlink is a reference comparable to a citation. The quantity, quality, and relevance of backlinks for a web page are among the factors that search engines like Google evaluate to estimate how important the page is. PageRank calculates the score for each web page based on how all the web pages are connected among themselves, and is one of the variables that Google Search uses to determine how high a web page should go in search results. This weighting of backlinks is analogous to citation analysis of books, scholarly papers, and academic journals.
Search engines often use the number of backlinks that a website has as one of the most important factors for determining that website's search engine ranking, popularity, and importance. Blog commenting, guest blogging, article submission, press release distribution, social media engagements, and forum posting can be used to increase backlinks.
Websites often employ SEO techniques to increase the number of backlinks pointing to their website. Some methods are free for use by everyone whereas some methods, like linkbaiting require quite a bit of planning and marketing to work. There are also paid techniques to increase the number of backlinks to a target site.
There are several factors that determine the value of a backlink. Backlinks from authoritative sites on a given topic are highly valuable. If both sites and pages have content geared toward the topic, the backlink is considered relevant and believed to have strong influence on the search engine rankings of the web page granted the backlink. Another important factor is the anchor text of the backlink. Search engine bots examine the anchor text to evaluate how relevant it is to the content on a web page.
What are Backlinks?
Backlinks are links to your website from other websites, and they're important because they can send traffic to your site and influence its organic (unpaid) visibility in search engines. This means they play a role in search engine optimization (SEO).
Google looks at the quantity and quality of backlinks to help gauge a site/page's authoritativeness. PageRank is a measure of page authority. And pages pass authority to each other through links.
The follow status affects the link:
rel="nofollow": This tells Google that the linking site doesn't want to endorse the target siterel="sponsored": This shows that the target site paid for the link to be placedrel="ugc": This indicates that the link appears within user-generated content (like forum comments)
The more authoritative the referring domain and page, the more valuable a backlink can be for your SEO. Topical relevance refers to how closely related the referring page/site and the target's page/site are. Links that are likelier to be clicked may pass more SEO value, because this signals that the link is more important to users. Search engines use the anchor text to better understand what the linked page is about.
