掌握外链周期 做好网站优化
谈起外链,各SEOer众说纷纭。就各大搜索引擎对外宣称的算法而言,外链的作用已是鸡肋——作之无用,舍之可惜,连笔者小丹都觉得它已经成为了网站优化中可有可无的存在。

  然,事实真是如此吗?虽然笔者也多次强调外链为皇的时代已经过去,网站内容才是排名制胜的关键。而就近几次搜索引擎更新和笔者网站的排名来看,外链的作用远远不是我们所说无用功,相反一些外链在整个优化过程中的比重还是很高的,初步数据计算大约可以占到网站运营中的30%—40%左右。

  这个数据就是外链向我们宣告它重要性的力证,就此笔者小丹今天要分享于大家网站优化经验之谈就是关于搜索引擎针对外链的标准。

  像所有的东东一样,外链在搜索引擎中也存在一个生命周期,这个周期可以根据它的作用力度分为新生期、作用期、失效期。

  第一,外链新生期。处于外链新生期就是最初外链在制作后的一段时间,这个时间大概是15天左右。其中,第一周可以被看成是外链的发现期,这段时间主要是spider要对外链进行爬行抓取;第二周就是对于外链的规整期及被收录外链的权重打分期,看看这些外链对于网站的作用及传递的权重。

  第二,外链作用期。这个时期是我们所做的外链真正发挥其效益的时候。我们可以站长统计类的网页上根据网站的浏览量来判断外链的价值,通过其稳定性、传递着、时效性来获得外链对于网站的作用力度,从而获得相关的优化数据来完善网站优化的各个步骤。

  第三,外链失效期。任何事物都是盛极必衰,外链也是一样的,在过度到这个时期后外链对于网站就不会再有传递权重和引导作用,再或者这些外链会在其网站数据更新中被删除。这也是大多网站管理者会不定期增加修补外链的原因,为了一个相对稳定的数值,不会给搜索引擎带来大起大落不稳定的印象。

  对于外链的认知和作用笔者小丹还会继续针对数据进行总结,就现阶段的数据分析,搜索引擎对于外链的判断标准集中在外链的数量、外链平台作用周期和外链发布的相关性三方面上。由此笔者认为,我们在制作外链时要尽量选择匹配度高的、作用周期比较长的平台网站上。
