外部链接对SEO的影响

相关性及锚文本

相关性是搜索结果质量的最重要指标。搜索引擎刚出现时，判断页面与关键词的相关性主要以页面上的元素为基础，也就是页面标题、可见文字等。在意义上说，也就是根据页面自己说与什么相关进行判断的。你说这个页面是什么就是什么。后来很多站长用这种行为作弊得到搜索流量，用户来到网站后，用户体验怎么样作弊者就不管了。　看页面自己怎么说的方法很快被证实不可靠，搜索引擎转而看别人怎么说，也就是通过外部链接及锚文字判断相关性。导入链接内容相关性及锚文字成为判断相关性及排名算法最重要的因素之一，尤其是来自其他网站的导入链接。

权重及信任度

外部链接使被链接的页面及整个域名权重提高，信任度增加。外部链接越多，发出链接的网站本身权重越高，说明被链接的页面受更多人的信任和尊重。投向一个页面的权重和信任度，也会累计在整个域名上。　权重是搜索引擎排名中非常重要的因素之一。形成权重中的最重要的因素就是外部链接。如果你的网站有来自权重极高网站的链接，你的网站的权重会有一定的提升，不管网站目标关键词是什么，排名都会有帮助。
