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。

如何布局外链才能有明显的效果？

怎样的外链策略才能有明显的效果。推荐方法如下：1、友情链接交换。2、现在的网站SEO人员或多或少都使用付费链接这种手段，毕竟花费少、见效快，搜索引擎也比较难以分辨，从目前看，这种方法性价比还是比较高的。3、拥有大量的导航站的链接，这些链接不是通常的直链，是网站购买了大量的导航站链接，后面的参数是跟踪订单来源的，目前搜索引擎对于cps链接对网站的加权作用并没有说得很明确，不过从实践上来看，这种外链的

健康的外部链接构成（下）

接健康的外部链接构成（上）连到网站内页的链接很多网站把外部链接建设的大部分精力、时间，都放在首页上了，造成绝大部分外部链接都是连向首页。这也是搜索引擎很容易判断的不健康的标志之一。使用雅虎链接指令，轻易就能查出连到首页的外部链接占整个网站外链的比例。如果绝大部分外部链接都是连到首页，就可能被判断过多使用友情链接，甚至链接工厂。我觉得这也是为什么很多博客排名不错的原因之一，因为博客的外部链接构成自
