站点流量异常追查文档-相关因素之外链爆增

#### 一、外链爆增原因分析对于站点的流量异常，通常可以分析出是通过相关因素使站点受到影响，也可能是外链爆增造成的，以下是分析外链爆增的一些原因： 1. 因为有新的品牌和产品加入，建立了与站点有关的外链； 2. 其他站点、门户网站等有重要消息和链接指向该站点； 3. 网站以搜索引擎推广会增加链接数量； 4. 站点被推广到论坛或博客，增加第三方外链； 5. 有新内容发布其他站点转发； 6. 站点在社交媒体和论坛上受到普及，影响力扩大； 7. 站点被其他站点和搜索引擎标记为主题页或链接收录导致外链爆增等等。 #### 二、外链爆增追查方法 1. 对站点外链进行详细剖析并比较：可以通过站点外链指数系统收集站点外链状况，然后找出新增的外链，进而分析源头； 2. 通过百度和搜狗等搜索引擎检查该站点的外部链接质量的升降； 3. 查询流量：分析外链可以帮助我们溯查流量波动的源头，通过外链分析系统可以分析每个外链的贡献量； 4. 查看站点新增的外链是否有来自潜在的竞争对手或有害站点，做出正确的应对； 5. 查看站点是否被搜索引擎标记为不良链接，及时删除被判定为不良链接的垃圾外链； 6. 及时查看新增外链的数量变化，并做出相应的应急措施，以降低外链的数量。

站点流量异常追查文档-特征页分析

特征页分析是站点流量异常追查中的一项重要步骤，通过分析站点的特征页可以发现异常流量的特征和规律，并据此进一步追查异常流量的来源和原因。下面是一份站点流量异常追查的特征页分析文档示例： 1. 异常流量起始时间：记录异常流量的起始时间，用于后续的时间段分析。 2. 特征页URL：列出异常流量的特征页URL，即被异常流量访问频率较高的页面。 3. 访问频率统计：统计每个特征页的访问次数以及占总访问
