Most popular search algorithms establish a "page rank" based on how many other pages link to it. There is a more complex process of crawling and indexing that is not in the scope of this page.

PageRank (a search algorithm used by google) 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.<ref>https://en.wikipedia.org/wiki/PageRank</ref>

HITS (Hyperlink-Induced Topic Search) assigns two scores for each page: its authority, which estimates the value of the content of the page, and its hub value, which estimates the value of its links to other pages.
