A link in its simplest form is a connection from one web site to another. Before there was a Google people primarily considered links as a means to get people to find their web site. Though links can still be used to drive visitors, the advent of Google in 1996 made links important also for search engine rankings. Google’s basic algorithm looks at the links pointing to a site as a measure of its importance then using this in conjunction with relevancy ranks a site. The Google algorithm gives a score for the importance of each link from a range of 0 to 10 called page rank (PR), named after the co-founder Larry Page. The score is almost logarithmic, so a PR3 is approximately 10 times more powerful than a PR2. Links are as varied as the sites which are doing the linking below are many of the common and not so common types of links.
