That intent is for the websites that rank high in the Google search engine to be useful to all of us. They also need to actually be seen as usful to other people. For a long time people have been paying for links from other websites to theirs instead of getting them naturally. You see, Google looks at those links as recommendations and a paid recommendation isn't respected by most people.
