If enough people link to a certain page on the Internet, it becomes a trusted source on a given topic—a truth, set in stone.
Presently, the Google search engine treats the number of incoming links to a webpage as an index of its quality. Therefore, a page that many other pages link to is ranked higher.
But what’s popular may not be authoritative. The result is that the Internet has way too much trash in it, masquerading as “truth.”
Google wants to change that.
It’s working on a new model that will rank websites not on the basis of how many incoming links they have, but on the accuracy of their content. A page that has few false “facts” will be considered trustworthy, and its ranking will rise.
