  协助断定页面在成果中应该排名多少
  
  一旦查找引擎在Web上抓取页面,它们就能够提取这些页面的内容并将其添加到索引中。经过这种办法,他们能够判别他们是否觉得页面质量足够好,能够很好地排在相关关键词上(谷歌创立了一个短片来解说这个进程)。当他们决议这一点时,查找引擎不只是检查页面的内容,还检查从外部网站指向该页面的链接数量以及这些外部网站的质量。一般来说,链接到你的网站越高,你在查找成果中的排名就越有可能。

  它之所以如此有用,是由于它根据一个观念,即一个链接能够被看作是对一个页面的信任投票,也就是说,假如它不值得链接,它就不会获得链接。该理论以为,当有人链接到另一个网站,他们实际上说这是一个很好的资源。不然,他们不会链接到它,就像你不会把朋友送到一家糟糕的饭馆相同。
